     BACKGROUND OF THE INVENTION 
     This invention relates to the use of novel methyl substituted pinyl oxopentenes defined according to the generic structure: ##STR1## and the generic structure: ##STR2## wherein Z represents methylidene defined according to the structure: ##STR3## ethylidene defined according to the structure: ##STR4## or ethylenyl defined according to the structure: ##STR5## wherein one of the dashed lines represents a carbon-carbon single bond and the other of the dashed lines represents no bond; wherein n is 0 or 1 and m is 0 or 1 with the sum of n+m being equal to 1; wherein X represents carbinol having the structure: ##STR6## or ketone having the structure: ##STR7## wherein R 1 , R 2 , R 3  and R 4  represent hydrogen or methyl; wherein one of the lines: 
     
         ++++ 
    
     represents a carbon-carbon single bond and the other of the lines: 
     
         ++++ 
    
     represents a carbon-carbon single bond or a carbon-carbon double bond; wherein one of the lines: 
     
         /+/+/+/+/+/ 
    
     represents a carbon-carbon single bond and the other of the lines: 
     
         /+/+/+/+/+/ 
    
     represents a carbon-carbon single bond or a carbon-carbon double bond; with the provisos that: 
     (i) when R 3  and R 4  are each hydrogen, the dashed line at the 7-5 position is a carbon-carbon single bond; n=0 and m is 1; Z represents ethylidene having the structure: ##STR8##  or ethylenyl having the structure: ##STR9## (ii) when one of R 3  or R 4  is methyl, then either the dashed line at the 7-5 position or the dashed line at the 7-4 position is a carbon-carbon single bond; and Z represents methylidene defined according to the structure: ##STR10## (iii) when R 3  is methyl, then n is 1 and m is 0 and R 4  is hydrogen; and 
     (iv) when R 4  is methyl, then R 3  is hydrogen, n is 0 and m is 1; 
     and wherein one of the lines: ##STR11## represents a carbon-carbon double bond and the other of the line: ##STR12## represents a carbon-carbon single bond; and uses thereof in augmenting or enhancing the aroma or taste of consumable materials. 
     Materials which can provide sandalwood-like, urine-like and musky aromas with floral and muguet undertones are desirable and are known in the art of perfumery. Many of the natural materials which provide such fragrances and such desired nuances to perfumery compositions and perfumed articles are high in cost, vary in quality from one batch to another and/or are generally subject to the usual variations of natural products. 
     By the same token, materials which can provide ionone-like, raspberry-like, oriental, floral, violet, musky and fruity aromas with sweet, ionone-like, raspberry, fruity and lactonic tastes are desirable and are well known in the art of flavoring for foodstuffs, toothpastes, chewing gums, medicinal products and chewing tobaccos. Many of the natural materials which provide such flavor notes and contribute such desired nuances to flavor and to compositions are high in cost, vary in quality from one batch to another and/or are generally subject to the usual variations of natural products. 
     By the same token, materials which can provide sweet, woody, oriental, ionone-like, sandalwood-like, patchouli-like and cigar box-like aroma and taste nuances to smoking tobacco or smoking tobacco article components both prior to smoking and on smoking in the main stream and in the side stream are highly desirable and are well known in the art of flavoring for smoking tobacco and components for smoking tobacco articles such as filters and wrappers. Many of the natural materials which provide such aroma and taste nuances and contribute the desired nuances to tobacco flavoring compositions are high in cost, vary in quality from one batch to another and/or are generally subject to the usual variations of natural products. 
     Artificial flavoring agents for foodstuffs have received increasing attention in recent years. For many years such food flavoring agents have been preferred over natural flavoring agents at least in part due to their diminished cost and their reproducible flavor qualities. For example, natural food flavoring agents such as extracts, concentrates and the like are often subject to wide variations due to changes in quality, type and treatment of the raw materials. Such variations can be reflected in the end products and result in unfavorable flavor characteristics in said end product, for example, blackberry, peach and tropical fruit flavored foodstuffs. Additionally, the presence of the natural product in the ultimate food may be undesirable because of increased tendency to spoil. This is particularly troublesome in food and food uses where such products as dips, soups, chips, sausages, gravies and the like are apt to be stored prior to use. 
     The fundamental problem in creating artificial flavor agents is that the artificial flavor to be achieved be as natural as possible. This generally proves to be a difficult task since the mechanism for flavor development in many foods, medicinal products, chewing gums and toothpastes is not completely known. This is particularly noticeable in products having blackberry, peach and tropical fruit characteristics particularly. 
     Even more desirable are products which can serve to substitute for difficult to obtain natural perfumery oils and, at the same time, substitute for natural flavoring ingredients in foodstuffs, chewing gums, medicinal products, toothpastes, chewing tobaccos, and smoking tobaccos. 
     Pinyl pentenol derivatives are known in the art for having sandalwood aromas. Thus, the compound having the structure: ##STR13## is shown to be prepared according to German Offenlegungsschrift No. 2708048 which, generically, discloses synthesis of compounds defined according to the structure: ##STR14## wherein R 1  and R 2  taken together can represent dimethyl bicyclo[3.1.1] heptyl; R 3  represents alkyl; R 4  represents alkyl and Y represents a divalent aliphatic group with at least four carbon atoms. Thus, German Offenlegungsschrift No. 2708048 discloses the reaction sequence, starting with pinene and ending up with a tertiary pentenol thusly: ##STR15## None of the chemicals produced using the process of our invention are tertiary alcohols and the chemicals produced according to the process of our invention are not considered to be similar from a chemical and organoleptic standpoint to the compounds of German Offenlegungsschrift No. 2708048.

     German Offenlegungsschrift No. 2849742 abstracted in Chem. Abstracts 1981, No. 186613a (Hagen and Bruns) published May 22, 1980  discloses the hydroformylation of monocyclic or bicyclic terpenes with at least one double bond in the presence of a rhodium complex containing triphenylphosphine at 70°-160° C. at 100-400 bar to give the corresponding terpenecarboxaldehydes and alleges that these terpenecarboxaldehydes are useful as perfume ingredients.

     The resulting mixture of aldehydes may then be separated for subsequent reaction or may be used as is and is preferably used as is as a mixture (which is the most economical way to proceed). The mixture or individual aldehydes are then reacted with methyl ethyl ketone according to the reactions: ##STR52## whereby a mixture of ketones is produced. This reaction is carried out under standard &#34;aldol&#34; condensation reaction conditions, that is, using a basic catalyst and reflux conditions with the basic catalyst being sodium hydroxide, potassium hydroxide, lithium hydroxide, barium hydroxide or calcium hydroxide. The reaction can be carried out using a &#34;Soxhlet&#34; apparatus in the laboratory or analogous apparatus in the plant. The reaction temperature may vary from about 40° C. up to about 150° C. and is preferably carried out at reflux conditions at atmospheric pressure. However, the reaction may be carried out at higher pressures and higher temperatures in pressure equipment which preferably is either glass-lined pressure equipment or stainless steel pressure equipment. At the end of the reaction, the reaction mixture is distilled by means of fractional distillation and the resulting products in admixture may be used &#34;as is&#34; for their organoleptic properties or may be used &#34;as is&#34; for further reaction or may be separated by means of commercial chromatographic techniques, e.g. &#34;HPLC&#34; techniques. 
     The resulting reaction product may be reduced using lithium aluminum hydride, sodium borohydride or potassium borohydride reducing agents according to the reactions: ##STR53## taken together with the reaction: ##STR54## These reactions are preferably carried out in a solvent which is inert to the reaction mass such as diethylether or tetrahydrofuran under reflux conditions at atmospheric pressure. The reaction may be carried out at pressures higher than atmospheric at higher temperatures thereby resulting in shorter times of reaction. However, the yield of reaction product is not affected by the higher temperature of reaction. However, higher temperatures will vary the ratio of isomeric products produced without, however, materially affecting the organoleptic properties thereof. At the end of the reaction, the reaction product may be used &#34;as is&#34; for its organoleptic properties after appropriate fractional distillation or the reaction product after fractional distillation may be separated into the individual components of the mixture by standard chromatographic techniques, e.g. HPLC techniques. 
     Examples of mixtures of products and individual products produced according to the foregoing reaction sequence are set forth in Table I, infra:

     When the methyl substituted pinyl oxopentenes of our invention are used as food flavor adjuvants, the nature of the co-ingredients included with the methyl substituted pinyl oxopentenes of our invention used in formulating the product composition will also serve to alter, modify, augment or enhance the organoleptic properties of the ultimate foodstuff treated therewith. 
     As used herein as regards to flavor, the terms &#34;alter&#34;, &#34;modify&#34; and &#34;augment&#34; in their various forms mean &#34;supplying or imparting flavor character or note to otherwise bland, relatively tasteless substances or augmenting the existing flavor characteristic where a natural flavor is deficient in some regard or supplementing the existing flavor impression to modify its quality, character or taste&#34;. 
     The term &#34;enhance&#34; is used herein to mean the intensification of a flavor or aroma characteristic or note without the modification of the quality thereof. Thus, &#34;enhancement&#34; of a flavor or aroma means that the enhancement agent does not add any additional flavor note. 
     As used herein, the term &#34;foodstuff&#34; includes both solid and liquid ingestible materials which usually do, but need not have nutritional value. Thus, foodstuffs include soups, convenience foods, beverages, dairy products, candies, chewing gums, vegetables, cereals, soft drinks, snacks and the like. 
     As used herein, the term &#34;medicinal product&#34; includes both solids and liquids which are ingestible non-toxic materials which have medicinal value such as cough syrups, cough drops, aspirin and chewable medicinal tablets. 
     The term &#34;chewing gum&#34;, is intended herein to mean a composition which comprises a substantially water-insoluble, chewable plastic gum base such as chicle or substitutes therefor, including jelutong, guttakay, rubber or certain cosmetible natural or synthetic resins or waxes. Incorporated with the gum base in admixture therewith may be plasticizers or softening agents, e.g. glycerine, and a flavoring composition which incorporates one or more of the substituted norbornane carboxaldehyde derivatives of our invention, and in addition, sweetening agents which may be sugars, including sucrose or dextrose and/or artificial sweeteners such as cyclamates or saccharin. Other optional ingredients may also be present. 
     Substances suitable for use herein as co-ingredients or flavoring adjuvants are well known in the art for such use, being extensively described in the relevant literature. It is a requirement that any such material be &#34;ingestibly&#34; acceptable and thus non-toxic and otherwise non-deleterious, particularly from an organoleptic standpoint whereby the ultimate flavor and/or aroma of a consumable material used is not caused to have unacceptable aroma and taste nuances. Such materials may in general be characterized as flavoring agents or vehicles comprising broadly stabilizers, thickeners, surface agents, conditioners, other flavorants and flavor intensifiers. 
     Stabilizer compounds include preservatives, e.g. sodium chloride, antioxidants, e.g. calcium and sodium ascorbate, ascorbic acid, butylated hydroxy-anisole (mixture of 2- and 3-tertiary-butyl-4-hydroxy-anisole), butylated hydroxy toluene (2,6-di-tertiary-butyl-4-methyl phenol), propyl gallate and the like and sequestrants, e.g. citric acid. 
     Thickener compounds include carriers, binders, protective colloids, suspending agents, emulsifiers and the like, e.g. agar agar, carrageenan, cellulose and cellulose derivatives such as carboxymethyl cellulose and methyl cellulose; natural and synthetic gums such as gum arabic, gum tragacanth, gelatin, proteinaceous materials, lipids, carbohydrates; starches, pectins and emulsifiers, e.g. mono- and diglycerides of fatty acids, skim milk powder, hexoses, pentoses, disaccharides, e.g. sucrose, corn syrup and the like.

     The specific flavoring adjuvant selected for use may be either solid or liquid depending upon the desired physical form of the ultimate product, i.e. foodstuff, whether simulated or natural, and should, in any event, (i) be organoleptically compatible with the methyl substituted pinyl oxopentenes of our invention by not covering or spoiling the organoleptic properties (aroma and/or taste) thereof; (ii) be non-reactive with the methyl substituted pinyl oxopentenes of our invention and (iii) be capable of providing an environment in which the methyl substituted pinyl oxopentenes of our invention can be dispersed or admixed to provide a homogeneous medium. In addition, selection of one or more flavoring adjuvants, as well as the quantities thereof will depend upon the precise organoleptic character desired in the finished product. Thus, in the case of flavoring compositions, ingredient selection will vary in accordance with the foodstuff, chewing gum, medicinal product or toothpaste to which the flavor and/or aroma are to be imparted, modified, altered or enhanced. In contradistinction, in the preparation of solid products, e.g. simulated foodstuffs, ingredients capable of providing normally solid compositions should be selected such as various cellulose derivatives. 
     As will be appreciated by those skilled in the art, the amount of the methyl substituted pinyl oxopentenes employed in a particular instance can vary over a relatively wide range, depending upon the desired organoleptic effects to be achieved. Thus, correspondingly greater amounts would be necessary in those instances wherein the ultimate food composition to be flavored is relatively bland to the taste, whereas relatively minor quantites may suffice for purposes of enhancing the composition merely deficient in natural flavor or aroma. The primary requirement is that the amount selected be effective, i.e. sufficient to alter, modify or enhance the organoleptic characteristics of the parent composition, whether foodstuff per se, chewing gum per se, medicinal product per se, toothpaste per se, or flavor composition. 
     The use of insufficient quantities of methyl substituted pinyl oxopentenes will, of course, substantially vitiate any possibility of obtaining the desired results while excess quantities prove needlessly costly and in extreme cases, may disrupt the flavor-aroma balance, thus proving self-defeating. Accordingly, the terminology &#34;effective amount&#34; and &#34;sufficient amount&#34; is to be accorded a significance in the context of the present invention consistent with the obtention of desired flavoring effects. 
     Thus, and with respect to ultimate food compositions, chewing gum compositions, medicinal product compositions and toothpaste compositions, it is found that quantities of methyl substituted pinyl oxopentenes ranging from a small but effective amount, e.g. 0.02 parts per million up to about 300 parts per million based on total composition are suitable. Concentrations in excess of the maximum quantity stated are not normally recommended, since they fail to provide commensurate enhancement of organoleptic properties. In those instances wherein methyl substituted pinyl oxopentenes are added to the foodstuff as an integral component of a flavoring composition, it is, of course, essential that the total amount of flavoring composition employed by sufficient to yield an effective concentration of methyl substituted pinyl oxopentenes in the foodstuff product. 
     Food flavoring compositions prepared in accordance with the present invention preferably contain methyl substituted pinyl oxopentenes in concentrations ranging from about 0.1% up to about 15% by weight of the total weight of the said flavoring composition. 
     The composition described herein can be prepared according to conventional techniques well known as typified by cake batters and fruit drinks and can be formulated by merely admixing the involved ingredients within the proportions stated in a suitable blender to obtain the desired consistency, homogeneity of dispersion, etc. Alternatively, flavoring compositions in the form of particulate solids can be conveniently prepared by mixing methyl substituted pinyl oxopentenes with, for example, gum arabic, gum tragacanth, carrageenan and the like, and thereafter spray-drying the resultant mixture whereby to obtain the particulate solid product. Pre-prepared flavor mixes in powder form, e.g. fruit flavored powder mixes, are obtained by mixing the dried solid components e.g. starch, sugar and the like and one or more methyl substituted pinyl oxopentenes in a dry blender until the requisite degree of uniformity is achieved. 
     It is presently preferred to combine with methyl substituted pinyl oxopentenes of our invention, the following adjuvants:

     The methyl substituted pinyl oxopentenes of our invention can be used to contribute sandalwood, urine-like, animal-like aromas with floral and muguet undertones and woody topnotes to perfume compositions, perfumed articles such as solid or liquid anionic, cationic, nonionic or zwitterionic detergents, fabric softener compositions, fabric softener articles, fabric optical brighteners, fabric conditioners, hair preparations and perfumed polymers. As olfactory agents, the methyl substituted pinyl oxopentenes of our invention can be formulated into or used as components of a perfume composition. 
     The term &#34;perfume composition&#34; is used herein to mean a mixture of organic compounds including for example, alcohols, aldehydes, ketones, nitriles, ethers, lactones and frequently hydrocarbons which are admixed so that the combined odors of the individual components produce a pleasant or desired fragrance. Such perfumed compositions usually contain (a) the main note of the &#34;bouquet&#34; or foundation stone of the composition; (b) modifiers which round off and accompany the main note; (c) fixatives which include odorous substances which lend a particular note to the perfume throughout all stages of evaporation, and substances which retard evaporation and (d) topnotes which are usually low-boiling, fresh-smelling materials. 
     In perfume compositions, the individual component will contribute its particular olfactory characteristics, but the overall effect of the perfume composition will be the sum of the effect of each ingredient. Thus, the individual compounds of this invention, or mixtures thereof, can be used to alter the aroma characteristics of a perfume composition, for example, by highlighting or moderating the olfactory reaction contributed by another ingredient in the composition. 
     The amount of methyl substituted pinyl oxopentenes of our invention which will be effective in perfume compositions depends upon many factors including the other ingredients, their amounts and the effects which are desired. It has been found that perfume compositions containing as little as 0.5% of the methyl substituted pinyl oxopentenes of our invention or even less in perfume compositions containing as much as 70% of the methyl substituted pinyl oxopentenes of our invention can be used to impart interesting, sandalwood, animal-like, musky and urine-like aromas with floral and muguet undertones to perfumed articles, perfume compositions and colognes. Such perfumed articles include fabric softener compositions, perfumed polymers (e.g. perfumed microporous polyethylene and microporous polypropylene), drier-added fabric softeners, cosmetic powders, talcs, and solid or liquid anionic, cationic, nonionic or zwitterionic detergents. The amount employed can range up to 70% and will depend on considerations of cost, nature of the end product and the effect desired on the finished product and the particular fragrance sought. 
     Thus the methyl substituted pinyl oxopentenes of our invention can be used alone or in a perfume composition as an olfactory component in solid or liquid anionic, cationic, nonionic or zwitterionic detergents (including soaps), space odorants and deodorants; perfumes; colognes, toilet water, bath salts, hair preparations such as lacquers, brilliantines, pomades and shampoos; cosmetic preparations such as creams, deodorants, hand lotions and sun screens; powders such as talcs, face powders, dusting powders; perfumed polymers such as perfumed microporous thermoplastic polymers, e.g. perfumed polyethylene, perfumed polyrpopylene, perfumed polyesters or perfumed thermoset resins such as cross-linked polyacrylates, cross-linked polyurethanes and the like. 
     When used as an olfactory component of a perfumed article such as a solid or liquid anionic, cationic, nonionic or zwitterionic detergent or of a cosmetic powder or of a plastic polymer, as little as 0.01% of one or more of the methyl substituted pinyl oxopentenes of our invention will suffice to provide interesting musky, woody, animal-like, sandalwood-like aromas with floral and muguet undertones. Generally no more than 0.8% of the methyl substituted pinyl oxopentenes of our invention are required. 
     Thus the range of methyl substituted pinyl oxopentenes in the perfumed article may vary from about 0.01% up to about 0.8% of the overall perfumed article. 
     In addition, the perfume compositions of our invention can contain a vehicle or carrier for the methyl substituted pinyl oxopentenes of our invention alone or with other ingredients. The vehicle can be a liquid such as an alcohol such as ethanol, a glycol such as propylene glycol or the like. The carrier can be an absorbent solid such as a gum (e.g. xanthan gum or guar gum), or components for encapsulating the composition as by coacervation (e.g. gelatin) or as by polymerization around a liquid perfume oil core as by polymerization of a urea formaldehyde polymer. 
     Also contemplated within the scope of this invention are mixtures of the methyl substituted pinyl oxopentenes of our invention taken further together with: 
     (i) 4-methyl-3-cyclohexene-1-carboxylic acid having the structure: ##STR61##  taken alone or taken further together with other compounds which yield sweaty, animal, leathery notes defined according to genera having the structures: 
     (ii) ##STR62##  wherein R represents t-butyl or t-amyl as more specifically described in U.S. Pat. No. 3,702,343 issued on Nov. 7, 1972, the disclosure for which is incorporated by reference herein. 
     In addition to the methyl substituted pinyl oxopentenes of our invention and to the compounds having the structure: ##STR63## and/or the compounds defined according to the structures: ##STR64## it is contemplated that these compounds can also be used in admixture with cedrol alkyl ethers disclosed in U.S. Pat. No. 3,373,208 issued on Mar. 12, 1968, the disclosure of which is incorporated by reference herein. The cedrol alkyl ethers of U.S. Pat. No. 3,373,208 are defined according to the generic structure: ##STR65## wherein R represents methyl, ethyl, propyl, butyl, allyl or methallyl. 
     Contemplated within the scope of our invention are ratios of methyl substituted pinyl oxopentenes:4-methyl-3-cyclohexene-1-carboxylic acid or 2-methyl-2-(t-alkyl cyclohexyl ) pentan-4-one or cedrol alkyl ethers of from 1:30 to 30:1 (mole ratios). 
     The compounds defined according to the structure: ##STR66## may be prepared by methods well known in the art, e.g. according to the reaction: ##STR67## as further disclosed in Example I of application for U.S. patent Ser. No. 391,592 filed on June 24, 1982, now U.S. Pat. No. 4,390,434 issued on June 28, 1983, the disclosure of which is incorporated by reference herein. 
     When using the mixtures of our invention, that is the methyl substituted pinyl oxopentenes and the compounds defined according to the structure: ##STR68## or the compounds defined according to the structures: ##STR69## or the compound defined according to the structure: ##STR70## the additional notes provided to the perfume compositions or perfumed articles as set forth, supra, are cumin-like, sweaty, and cedar-like with castoreum undertones. 
     Furthermore, the methyl substituted pinyl oxopentenes produced according to the processes of our invention are capable of supplying and/or potentiating certain flavor and aroma notes usually lacking in many tobacco flavors heretofore provided. 
     As used herein in regard to tobacco flavors, the terms &#34;alter&#34; and &#34;modify&#34; in their various forms mean &#34;supplying or imparting flavor character or note to otherwise bland tobacco, tobacco substitutes, or tobacco flavor formulations or augmenting the existing flavor characteristic where a natural flavor is deficient in some regard or supplementing the existing flavor impression to modify its quality, character or taste&#34;. 
     As used herein, the term &#34;enhance&#34; is intended to mean the intensification (without change in kind of quality of aroma or taste) of one or more taste and/or aroma nuances present in the organoleptic impression of tobacco or a tobacco substitute or a tobacco flavor. 
     Our invention thus provides an organoleptically improved smoking tobacco product and additives therefor as well as methods of making the same which overcome specific problems heretofore encountered in which specific desired Turkish-type, oriental or Virginia tobacco aroma and taste nuances thereof are created or enhanced and may be readily controlled and maintained at the desired uniform level regardless of variations in the tobacco components of the blend. 
     This invention further provides improved tobacco additives and methods whereby various Virginia-type, oriental-type and Turkish-type tobacco notes may be imparted to smoking tobacco products and may be readily varied and controlled to produce the desired uniform flavor characteristics. 
     In carrying out this aspect of our invention, we add to smoking tobacco materials or a suitable substitute therefor (e.g. dried lettuce leaves) an aroma and flavor additive containing as an active ingredient one or more methyl substituted pinyl oxopentenes produced according to the processes of our invention. 
     In addition to the methyl substituted pinyl oxopentenes produced according to the processes of our invention, other flavoring and aroma additives may be added to the smoking tobacco materials or substitute therefor either separately or in admixture with the methyl substituted pinyl oxopentenes produced according to the processes of our invention as follows: 
     (i) 
     Synthetic Materials: 
     Beta-ethyl-cinnamaldehyde; 
     Beta-cyclohomocitral;

     Beta-damascone; 
     Maltol; 
     Ethyl maltol; 
     Delta-undecalactone; 
     Delta-decalactone; 
     Benzaldehyde; 
     Amyl acetate; 
     Ethyl butyrate;

     Dodecahydro-3a,6,6,9a-tetramethylnaphthol[2,1,b]-furan; 
     4-hydroxy hexanoic acid, gamma lactone and polyisoprenoid hydrocarbons defined in Example V or U.S. Pat. No. 3,589,372, issued on June 29, 1971. 
     (ii) 
     Natural Oils: 
     Celery seed oil; 
     Coffee extract; 
     Bergamot oil; 
     Cocoa extract; 
     Nutmeg oil; 
     Origanum oil. 
     An aroma and flavoring concentrate containing one or more of the methyl substituted pinyl oxopentenes produced according to the processes of our invention and, if desired, one or more of the above indicated additional flavoring additives may be added to the smoking tobacco material, to the filter or to the leaf or paper wrapper. The smoking tobacco material may be shredded, cured, cased and blended tobacco material or reconstituted tobacco material or tobacco substitutes (e.g. lettuce leaves) or mixtures thereof. The proportions of flavoring additives may be varied in accordance with taste but insofar as enhancement or the imparting of natural and/or sweet and/or woody, e.g. sandalwoody, and/or oriental notes, we have found that satisfactory results are obtained if the proportion by weight of the sum total of the methyl substituted pinyl oxopentenes produced according to the processes of our invention to smoking tobacco material is between 200 ppm and 2,000 ppm (0.02%-0.20%) of the active ingredients to the smoking tobacco material. We have further found that satisfactory results are obtained if the proportion by weight of the sum total of the methyl substituted pinyl oxopentenes produced according to the processes of our invention used to flavoring material is between 2,500 and 15,000 ppm (0.25%-1.5%). 
     Any convenient method for incorporating the methyl substituted pinyl oxopentenes produced according to the processes of our invention in the tobacco product may be employed. Thus, the methyl substituted pinyl oxopentenes produced according to the processes of our invention taken alone or along with other flavoring additives may be dissolved in a suitable solvent such as ethanol, n-pentane, diethylether, and/or other volatile organic solvents and the resulting solution may either be sprayed on the cured, cased and blended tobacco material or the tobacco material may be dipped into such solution. Under certain circumstances, a solution of the methyl substituted pinyl oxopentenes produced according to the process of our invention taken alone or further together with other flavoring additives as set forth above, may be applied by means of a suitable applicator such as a brush or roller on the paper or leaf wrapper for the smoking product, or it may be applied to the filter by either spraying, dipping or coating. 
     Furthermore, it will be apparent that only a portion of the tobacco or substitute therefor need be treated and the thus treated tobacco may be blended with other tobaccos before the ultimate tobacco product is formed. In such cases, the tobacco treated may have the methyl substituted pinyl oxopentenes produced according to the process of our invention in excess of our invention in excess of the amounts or concentrations above indicated so that when blended with other tobaccos, the final product will have the percentage within the indicated range. 
     In accordance with one specific example of our invention, an aged, cured and shredded domestic burley tobacco is sprayed with a 20% ethyl alcohol solution of the mixture of alcohols produced according to Example V, infra (bulked fractions 10-20 of the distillation product) defined according to the formula: ##STR71## taken together with the compounds defined according to the structure: ##STR72## (wherein in the mixture, in each of the compounds Z represents methylidene defined according to the structure: ##STR73## ethylidene defined according to the structure: ##STR74## or ethylenyl defined according to the structure: ##STR75## wherein one of the dashed lines represents a carbon-carbon single bond and the other of the dashed lines represents no bond; wherein n is 0 or 1 and m is 0 or 1 with the sum of n+m being equal to 1; wherein R 1 , R 2 , R 3  and R 4  represent hydrogen or methyl; wherein one of the lines: 
     
         ++++ 
    
     represents a carbon-carbon single bond and the other of the lines: 
     
         ++++ 
    
     represents a carbon-carbon single bond or a carbon-carbon double bond; wherein one of the lines: 
     
         /+/+/+/+/+/ 
    
     represents a carbon-carbon single bond and the other of the lines: 
     
         /+/+/+/+/+/ 
    
     represents a carbon-carbon single bond or a carbon-carbon double bond; with the provisos that: 
     (i) when R 3  and R 4  are each hydrogen, the dashed line at the 7-5 position is a carbon-carbon single bond; n=0 and m is 1; Z represents ethylidene having the structure: ##STR76##  or ethylene having the structure: ##STR77## (ii) when one of H 3  or R 4  is methyl, then either the dashed line at the 7-5 position or the dashed line at the 7-4 position is a carbon-carbon single bond; and Z represents methylidene defined according to the structure: ##STR78## (iii) when R 3  is methyl, then n is 1 and m is 0 and R 4  is hydrogen; and 
     (iv) when R 4  is methyl, then R 3  is hydrogen, n is 0 and m is 1 
     and wherein one of the lines: ##STR79## is a carbon-carbon double bond and the other of the lines: ##STR80## is a carbon-carbon single bond) in an amount to provide a tobacco composition containing 800 ppm by weight of the mixture of alcohols of Example V, infra, on a dry basis. Thereafter, the volatile ethyl alcohol is removed by evaporation and the tobacco is manufactured into cigarettes by the usual techniques. The cigarettes, when treated as indicated, have desired and pleasing aromas (increased smoke body sensation in the mouth with enhanced tobacco-like notes and pleasant aromatic nuances) which is detectable in the main and side streams when the cigarette is smoked. This aroma is described as having sweet, woody, sandalwood, patchouli, Havana cigar and burley characteristics. 
     While our invention is particularly useful in the manufacture of smoking tobacco, such as cigarette tobacco, cigar tobacco and pipe tobacco, other tobacco products formed from sheeted tobacco dust or fines may also be used. Likewise, the methyl substituted pinyl oxopentenes produced according to the processes of our invention can be incorporated with materials such as filter tip materials, seam paste, packaging materials and the like which are used along with tobacco to form a product adapted for smoking. Furthermore, the methyl substituted pinyl oxopentenes produced according to the process of our invention can be added alone or in admixture to certain tobacco substitutes of natural or synthetic origin (e.g. dried lettuce leaves) and, accordingly, by the term &#34;tobacco&#34; as used throughout this specification, is meant any composition intended for human consumption by smoking whether composed of tobacco plant parts, substitute materials or both. 
     The following examples serve to illustrate our invention and the invention is to be considered restricted thereto only as indicated in the appended claims. 
     All parts and percentages given herein are by weight unless otherwise specified.

     To a first portion of this basic formulation, a mixture of the ketones of Example IV is added at the rate of 1% (bulked fractions 10-20). To the second portion, nothing is added. 
     To a third portion of this basic formulation, a mixture of the compounds having the structures: ##STR125## (produced according to Example II of U.S. Pat. No. 4,284,824) is added at the rate of 1% and a mixture of the ketones produced according to Example IV supra (bulked fractions 10-20) is added at the rate of 1%. The three flavors are compared at the rate of 100 parts per million by a bench panel of experts. 
     The flavor containing the mixture of ketones produced according to Example IV (bulked fractions 10-20) is considered to have a more raspberry kernel, more seedy, herbaceous and more natural character in both aroma and taste than the flavor without such ketones. The use of the compounds having the structures: ##STR126## further enhances the raspberry kernel, seedy character.

     The ripened raspberry and seedy raspberry kernel note of this raspberry juice is imparted in increased strength by the addition of the mixture of ketones (bulked fractions 10-20) prepared according to Example IV at the rate of from 0.01 ppm up to 10 ppm. 
     EXAMPLE VIII 
     To the raspberry formulation as set forth in Example VI, the mixture of ketones produced according to Example IV (bulked fractions 10-20) is added at the rate of 0.2%. This material is then called the &#34;test composition&#34;. The raspberry formulation without the mixture of ketones is called the &#34;control composition&#34;. 
     The test and control compositions are added to the food products described hereinafter in the proportions shown for 10 kilograms of material to be flavored: 
     Pudding: 5-10 grams (0.05-0.1%) 
     Cooked sugar: 15-20 grams (0.15-0.2%) 
     Cooked sugar--100 ml of sugar syrup (prepared by dissolving 1 kilogram of sucrose in 600 ml of water) and 20 grams of glucose are mixed together and slowly heated to 145° C. The flavor is added and the mass is allowed to cool and harden. 
     Pudding--to 500 ml of warmed milk are added with stirring a mixture of 60 grams sucrose and 3 grams of pectin. The mixture is boiled for a few seconds and the flavor is added. The mixture is allowed to cool. 
     The finished foodstuff samples are tested by a panel of trained persons who express their views about the flavor of the samples. All members of the panel prefer the test samples having a more distinguished ripened raspberry aroma with taste of the ripe raspberries and its seedy kernel note. 
     An improved effect occurs when a mixture of 25:25:50 of 2-(4-hydroxy-4-methylpentyl)-norbornadiene:compound having the structure: ##STR127## mixture of ketones produced according to Example IV (bulked fractions 10-20) at the rate of 0.02 parts per million up to about 10 parts per million.

     The Cab-O-Sil® is dispersed in the liquid raspberry flavor composition of Example VI with vigorous stirring thereby resulting in a viscous liquid. 71 parts by weight of the powder flavor composition of Part A, supra, is then blended into the said viscous liquid with stirring at 25° C. for a period of 30 minutes resulting in a dry, free-flowing, sustained release raspberry flavor powder. 
     EXAMPLE X 
     Ten parts by weight of 5-Bloom pigskin gelatin is added to ninety parts by weight water at a temperature of 150° F. The mixture is agitated until the gelatin is completely dissolved and the solution is cooled to 120° F. Twenty parts by weight of the liquid raspberry flavor composition of Example VI (containing the mixture of ketones produced according to Example IV, bulked fractions 10-20) is added to the solution which is then homogenized to form an emulsion having particle size typically in the range of 2-5 microns. This material is kept at 120° F. under which conditions the gelatin will not gel. 
     Coacervation is induced by adding, slowly and uniformly, 40 parts by weight of a 20% aqueous solution of sodium sulphate. During coacervation, the gelatin molecules are deposited uniformly about each oil droplet as a nucleus. 
     Gelation is effected by pouring the heated coacervate mixture into 1,000 parts by weight of 7% aqueous solution of sodium sulphate at 65° F. The resulting gelled coacervate may be filtered and washed with water at temperatures below the melting point of gelatin, to remove the salt.

     Preliminary tablets are prepared by slugging with flat-faced punches and grinding the slugs to 14 mesh. 13.5 grams dry Vitamin A acetate and 0.6 grams Vitamin D are then added as beadlets. The entire blend is then compressed using concave punches at 0.5 grams each. 
     Chewing of the resultant tablets yields a pleasant, long-lasting, consistently strong raspberry flavor for a period of 12 minutes.

     The resultant product is redried to a moisture content of 20%. On chewing, this tobacco has an excellent substantially consistent, long-lasting, licorice/raspberry flavor profile in conjunction with the tobacco note. 
     EXAMPLE XVI 
     Guava Nectar Flavor 
     At the rate of 0.02 parts per million to natural guava nectar is added a mixture of the alcohols prepared according to Example V (bulked fractions 1-17). The mixture of alcohols adds to the guava aroma and taste profile interesting musky, fruity, ionone and perfumy aroma characteristics with lactonic flavor characteristics causing the guava nectar to be much more natural-like having interesting &#34;peachy&#34; nuances. 
     EXAMPLE XVII 
     Papaya Nectar Composition 
     To natural papaya nectar is added the following materials: 
     i. natural lemon juice: 0.5% 
     ii. mixture of alcohols prepared according to Example V, bulked fractions 5-17: 0.5 ppm 
     The addition of the mixture of alcohols prepared according to Example V adds to this papaya nectar a very natural &#34;fruity&#34; lactonic aroma and taste profile making it much more aesthetically pleasing than the papaya nectar without the addition of the mixture of alcohols.

     The resulting mixture is added to processed mango juice at the rate of 10 ppm. The resulting mango juice has an excellent &#34;natural&#34;, fresh, fruity &#34;unprocessed&#34; flavor and is therefore preferred over &#34;processed mango juice&#34;.
