in the preferred embodiment , the subject antidotal food product is provided generally in the form of a cookie sandwich treat commonly consumed by and quite popular with young children . it generally exhibits the appearance , the texture , the friability , and the sweet flavor which typically characterize such cookie sandwich treats . accordingly , one antidotal food product formed in accordance with the overall invention concept as herein described may comprise a pair of biscuit - like wafers and a creamy , preferably white , filling sandwiched therebetween . the wafers may have a coloring resembling popular cookie or wafer like products commercially sold and easily identified by young children to obviously entice them to eat the antidotal food product of the subject invention . each wafer includes activated charcoal , corn syrup solids , compressible sucrose , chocolate cream flavor , vanilla dry flavor , and sweetener in the approximate weight range proportions indicated in table 1 . table 1______________________________________ approximate weight preferred weightcomposition percentage range percentage______________________________________activated 20 . 0 %- 60 . 0 % 40

flavoradditive 0 . 1 %- 1 . 0 % 0 . 3 % sweetener______________________________________ preferably , a pair of disk - shaped black wafers are formed in accordance with the proportions indicated in table 1 . the wafers exhibit a compressed granular texture and a degree of friability akin to that of a class of cookie treats quite popular with children . the degree of friability is such that the wafers are easily crumbled by the average biting force generated by even a very young child . the degree of friability is also such that the crumbled wafers may thereafter be effectively disintegrated by the subsequent chewing action generated by the given young child . subject to the allowable ranges of their component composition weight percentages , the wafers exhibit a degree of rich , sweet flavor to accompany their graham cracker - like crumbly texture . it is important that the sweet flavor of the wafers be sufficient to encourage substantial chewing prior to ingestion into the user &# 39 ; s gastro - intestinal tract . to enhance both the sweet flavor of the wafers , and to enhance the emulation of that readily identifiable class of cookie treats , a creamy white filling is sandwiched between a pair of wafers . the precise consistency , color , and taste of the filling is not important to the invention ; however , it is preferable that the filling be of a consistency similar to that found in commonly - consumed cookie sandwich treats , that its color is not one that is non - existent in a commonly consumed cookie sandwich treat , and that its flavor exhibit a sufficient sweet component to supplement or augment the sweet flavor of the wafers . the component compositions and their corresponding proportional weights of one suitable filling composition exhibiting such attributes are indicated in table 2 . table 2______________________________________ approximate weight preferred weightcomposition percentage range

______________________________________ turning now to each of the component compositions shown in table 1 for each wafer , the preferred sorbent composition is activated charcoal , a black , powdery substance characterized by an extraordinary porosity which gives its particles a high internal surface area . a medicinal grade of this activated charcoal is commercially available from a limited number of manufacturers worldwide in forms respectively exhibiting various levels of internal surface area . one line of medicinal grade activated charcoals is manufactured by american norit company having designations a supra , b supra , and usp xxii , respectively with characteristic surface areas of 2 , 000 , 1 , 400 , and 900 m 2 / g . medicinal grade activated charcoal characterized by even greater internal surface areas have been available in the past in the united states but are currently not available commercially . any medicinal activated charcoal may be used in the subject composition . a supra was chosen in the preferred embodiment since it represents the largest surface area charcoal currently commercially available in the united states . this may translate into a lesser quantity of charcoal product required . lab tests verify that activated charcoal of greater surface area exhibits greater adsorptivity per unit gram thereof . to the extent possible , therefore , it is preferable that activated charcoal of maximum surface area be incorporated into the subject wafer . this would not only tend to decrease the minimum weight percentage necessary in each wafer to enable the incorporation in greater proportional quantities of the other flavor - enhancing compositions , but would also quite simply lessen the dosage that must be ingested for decontamination of a given quantity of ingested toxin . referring to the other compositions accompanying activated charcoal in the subject wafer , several factors are of paramount importance in their selection . first , the accompanying compositions must provide for the otherwise tasteless , gritty activated charcoal , a friable , yet chewable texture and a pleasant degree of sweet flavor reminiscent of , if not identical to , a sweet cookie treat . the accompanying compositions must provide such attributes without substantially abating the adsorptivity of the activated charcoal ; that is , without interfering therewith . as will be discussed in following paragraphs , that is no trivial matter , as a number of component compositions incorporated into early prototypes of the subject wafer were found to unexpectedly diminish in significant manner the overall adsorptivity of the activated charcoal . the component compositions shown in table 1 , when combined in the proportional quantities indicated , were found to reduce the overall adsorptivity of activated charcoal in its pure form by only approximately 6 %. this was determined to be an acceptable tradeoff given the exceptional flavor , texture , and friability level attained in the wafer . the corn syrup solids composition is a solid form of a corn or glucose syrup which is generally a mixture of d - glucose , maltose , and maltodextrins derived by hydrolysis of corn starch from the action of various acids and enzymes . the composition serves both as a sweetener and a binding agent for binding the activated charcoal particles together in a compressed solid . the particular type of corn syrup solids composition is not important to the present invention , and any one of various corn syrups commercially available may be utilized . the compressible sucrose composition also serves both as a sweetener and a binding agent . it is preferably of the type commercially - available and known as di - pac . while it is not necessary to include both a compressible sucrose composition and a corn syrup solids composition , as indicated in table 1 , it was found that wafers incorporating only compressible sucrose as its binding agent exhibited an undesirably great degree of friability tending to crumble much too readily to retain the appearance and feel of a cookie or biscuit . wafers incorporating only corn syrup solids as their binding agent were found to exhibit an undesirably low degree of friability , appearing to be much too hard to be comfortably chewed by young children . a mixture , however , in substantially equal amounts of the two compositions proved to exhibit a desirable level of both friability and taste . the resulting wafers incorporating substantially equal amounts of compressible sucrose and corn syrup solids compositions exhibited the richness in flavor characteristic of the compressible sucrose coupled with enough wafer cohesiveness to prevent premature crumbling at the wafer edges . the remaining compositions in table 1 , namely the chocolate cream flavor , the vanilla dry flavor , and the additive sweetener , are commercially available flavor enhancers included to optimize the taste emulation of popular cookie products . although the chocolate cream flavor , the vanilla dry flavor , and the additive sweetener are not therapeutically active , they do provide an important function of the overall antidotal food product in that their combined presence optimizes the probability that the young child will ingest the antidotal food product in emergency conditions and thereby allow the therapeutically active ingredients to take effect . thus , such ingredients are important in the overall concept since they render the therapeutically active ingredients functional in a particular environment . other suitable flavoring composition may be incorporated to serve this purpose ; however , it is important to maintain the proportional quantities of such flavor enhancers at the low levels indicated in table 1 to prevent the occurrence of unexpected levels of adsorptivity interference with respect to the activated charcoal . accordingly , care must be taken not to introduce into the wafer in any amount a flavoring composition which , by its inherent properties , exhibits an inordinate tendency to interfere with activated charcoal adsorptivity . it was found in an early prototype of the subject wafer , for instance , that the incorporation of melted chocolate as a flavor enhancer caused a noticeable decrease in the activated charcoal &# 39 ; s adsorptivity . this was likely due to the inherent tendency of the melted chocolate to adhere to the charcoal particles and plug their pores to thereby measurably reduce the available adsorption surface area . regarding the component compositions of the filling composition shown in table 2 , such is important in that they combine in the indicated proportions to form a sweet , creamy filling which complements the dry , somewhat diluted sweetness of the wafers , tending thereby to prompt the user to chew the wafers over a longer period of time . this increased chewing time is important , for the more the wafer is chewed , the more the activated charcoal is dispersed . kinetics tests performed with various wafer prototypes , as discussed in following paragraphs , indicate that greater dispersement of the activated charcoal effects measurably faster rates of toxin adsorption . observations from numerous other tests indicate that the component compositions of the filling present no significant threat to adsorptivity of the activated charcoal contained in the wafers . accordingly , the choice of component compositions and their respective weight percentages are important to the present invention to the extent that they affect the consistency , color , and taste of the resulting filling . the particular choice of component compositions and their corresponding weight percentages are determined primarily by these considerations . the component compositions shown in table 2 are each devoid of a fat component , a feature desirable in light of interference tests . interference tests for various component compositions indicate that fat - containing compositions observably interfere with the activated charcoal contained in the wafers . referring now to the tests performed for the subject decontaminant food product , extensive tests were performed on each of the more than forty prototypes developed in the process of realizing a workable decontaminant food product that overcomes the shortcomings of the prior art . comparative kinetics tests to determine the rate at which a given prototype adsorbed a . toxin , equilibrium adsorption tests to determine the adsorption capacity of the given prototype , and , where necessary , interference tests to determine the degree by which isolated component compositions tend to diminish the adsorptivity of the activated charcoal in the given prototype were performed for each prototype under simulated conditions . the tested prototypes varied widely in their component compositions and the corresponding proportional quantities , and the most instructive of the test results obtained are discussed in following paragraphs . all tests were conducted in vitro by mixing a predetermined amount of a test substance into a stock solution . the in vitro stock solution used in each test consisted of 1 g / l of sodium salicylate dissolved in a simulated gastric fluid solution containing 2 . 0 g / l of nacl , 7 . 0 ml / l of 12 n strength concentrated hcl , and distilled water . the simulated gastric fluid was characterized in this form by a ph level of 1 . 2 , the salicylate at this ph level being more than 99 . 99 % in the form of undissociated salicylic acid , which is very similar in its properties to aspirin , or acetylsalicylic acid . equilibrium adsorption tests for determining the total amount of salicylate that a given test substance may potentially adsorb if allowed to attain equilibrium conditions was conducted with the following procedures . first , a predetermined amount of the substance to be tested was placed in a glass vial , and 20 ml of the stock solution was added to that vial . the vial was thereafter continuously shaken by placement on a shaking table for approximately 15 hours . this caused the test substance to fully disintegrate such that the activated charcoal contained therein attained virtually perfect adsorption equilibrium with the salicylate in the stock solution . the kinetics tests were conducted generally by performing the following steps . approximately 500 ml of the stock solution was poured into a one liter glass container . a predetermined quantity of the given test substance was then introduced into the solution in the glass container . the container was then placed on a shaking table and shaken thereby at a 60 cycles per minute oscillation frequency . samples were taken at various times . activated charcoal was filtered from each sample and the solution analyzed colorimetrically to determine the salicylate concentration corresponding to the given sample time . comparative kinetics test results for a cookie product formed by sandwiching a pair of wafers formulated in accordance with the preferred combination indicated in table 1 sandwiched about a filling formulated in accordance with table 2 are shown in fig1 . for this test , a cookie weighing 6 . 80 g ( 5 . 15 g wafers and 1 . 65 g filling ) was chewed vigorously by the individual conducting the test , then introduced into a given volume of the stock solution . at 40 % of the wafer weight , approximately 2 . 06 g of a supra activated charcoal was thereby introduced into the solution . as shown by curve 10 , the concentration of salicylate in the solution decreased from 1 . 0 g / l to under 0 . 2 g / l within 2 . 5 minutes after the cookie &# 39 ; s introduction into the solution . after this dramatic initial decrease , the rate of salicylate concentration decrease gradually declined until equilibrium conditions were reached ( not shown ). the superior adsorption performance of the subject decontaminant food product is apparent when curve 10 is compared with curve 20 plotting the decrease in salicylate concentration upon introduction therein of a commonly available prior art activated charcoal liquid suspension . curve 20 was obtained by introducing 11 g of actidose aqua , a liquid suspension commercially marketed by paddock labs , inc ., minneapolis , mn . that amount of actidose aqua was determined to contain approximately the equivalent amount of activated charcoal as contained in the cookie sample from which curve 10 was derived . comparison of the two curves indicates that the cookie formed in accordance with the present invention not only reduced the salicylate concentration in the simulated gastric fluid solution at a significantly faster rate , but also yielded a significantly greater overall reduction in that concentration than a comparable amount of actidose aqua suspension . at the five minute point , for instance , the salicylate concentration , upon introduction of the subject cookie , was slightly below 0 . 1 g / l , whereas the salicylate concentration upon introduction of actidose aqua into the solution was observed to be slightly below 0 . 5 g / l at that time . after 30 minutes , the salicylate concentration had diminished to approximately 0 . 03 g / l with the subject cookie , whereas it had begun to level off at approximately 0 . 15 g / l with actidose aqua . the degree of interference with the adsorptivity of the activated charcoal in the cookie sample corresponding to curve 10 may be determined by comparison with the adsorption performance of an appropriate quantity of the same activated charcoal alone . that adsorption performance is indicated by curve 30 , derived by introducing into the stock solution approximately 2 . 0 g of pure a supra activated charcoal powder . comparison of curves 10 and 30 does indicate a measure of interference with the charcoal &# 39 ; s adsorptivity ; and , while the resolution of the curves in fig1 is not sufficient to quantifiably represent that measure of interference , separately conducted equilibrium adsorption tests show that the interference is not at a significant level . those equilibrium adsorption tests conducted with pure a supra activated charcoal yielded an approximate 75 % adsorption compared to the 68 . 5 % adsorption obtained with a sample of the subject cookie . that equates to a reduction of approximately 6 . 5 % in the resulting adsorption of salicylate . in light of the vital benefits derived from the enticing flavor and friability of the subject decontaminant food product , the cost in adsorptivity would be found by most toxicological treatment professionals to be quite insignificant . the pleasant flavor introduced into each wafer by the additional component compositions not only encourage thorough and complete chewing which enhances the adsorption kinetics by dispersing the activated charcoal contained in the wafer , it also has a more direct effect on the charcoal dispersion . the pleasant flavor induces the user &# 39 ; s salivary glands to produce more saliva than it would otherwise produce in the absence of such a pleasant flavor . the additional saliva , in turn , serves as a vehicle for more efficient dispersion of the charcoal particles . referring now back to table 1 , it is preferable that a supra activated charcoal be incorporated into each wafer at a 40 % weight percentage . a reduction in the weight percentage of a supra activated charcoal leads to a corresponding reduction in the adsorptivity of the resulting cookie . this was borne out in equilibrium adsorption tests conducted with a 30 weight percent a supra powdered wafer wherein adsorption values in the range of 61 . 1 % to 64 . 9 % were observed . in tests with a 20 weight percent a supra powdered wafer sample , the range of adsorption values observed decreased to 44 . 9 % to 46 . 3 %. an increase in the weight percentage of a supra beyond 40 %, while possible without excessively detrimental effects on the resulting wafer &# 39 ; s flavor and friability , would nevertheless tend to reduce the wafer &# 39 ; s palatability to younger children who are more inclined than older consumers to reject a food product for lack of sweetness . other than the activated charcoal component , the other primary components of each wafer , the corn syrup solids ( css ) and the dipac compositions may be varied in their proportional quantities . those two compositions combine to form the main components of the flavored binding composition , and variations in their relative proportional quantities in that binding composition notably affect the flavor and friability of the resulting wafer . as shown in table 3 , the relative proportions of the css and dipac compositions , however , do not appear to affect the adsorptivity of the activated charcoal . table 3______________________________________relative proportions percent salicylate adsorbed______________________________________100 % css , 0 % dipac 68 . 49 % 75 % css , 25 % dipac 68 . 49 % 50 % css 50 % dipac , 68 . 22 % 0 % css , 100 % dipac 68 . 49 % ______________________________________ comparative evaluation of the wafers resulting from each binding composition formulation shown in table 3 indicates that the corn syrup solids component is a stronger binding agent than the dipac component . accordingly , a wafer incorporating the 100 % css -- 0 % dipac formulation was more resistant to finger - abrasion than was a wafer incorporating the 75 % css -- 25 % dipac formulation , which , in turn , was more resistant to finger abrasion than a wafer incorporating the 50 % css -- 50 % dipac formulation , or one incorporating the 0 % css -- 100 % dipac formulation . the resistance to abrasion of wafers incorporating the 50 % css -- 50 % dipac and the 0 % css -- 100 % dipac formulations were qualitatively , at least , indistinguishable . comparative flavor evaluation of wafers incorporating the formulations shown in table 3 indicates that a wafer incorporating the 100 % css -- 0 % dipac formulation had little , if any , sweet flavor . a wafer incorporating the 75 % css -- 25 % dipac formulation had a mildly sweet , subtle chocolate flavor . a wafer incorporating the 50 % css -- 50 % dipac formulation had a more defined sweet chocolate flavor , and a wafer incorporating 0 % css -- 100 % dipac had an even more distinct sweet chocolate flavor . it is thus preferable for the optimal combination of friability level and flavor to incorporate into each wafer a 50 % corn syrup solids -- 50 % dipac binding composition formulation . the filling composition formulated in accordance with table 2 offers a concentrated sugary flavor which supplements and augments the flavor of the wafers . often , however , consumed cookie sandwich treats are consumed in parts by children who first disassemble the sandwich by separating at least one wafer from the filling , then proceed to consume the separated parts in sequence rather than in toto . it is , therefore , preferable that the wafers in and of themselves exhibit substantial flavor to be desirable to the average young child &# 39 ; s palate separate and apart from any filling composition . the combination of component compositions shown in table 1 for each wafer of the subject decontaminant food product was obtained only after extensive testing of numerous formulations incorporating a wide variety of component compositions and in varying proportional quantities . one flavored binding agent considered in place of the corn syrup solids and dipac compositions was a composition commercially marketed as maltrin 700 , a tabletting agent . adsorbance tests conducted by combining the maltrin 700 with a sample of a supra activated charcoal , however , indicated that the maltrin 700 significantly interferes with the adsorptivity of the activated charcoal . in those tests , 0 . 0203 g of a supra activated charcoal was combined with 0 . 0779 g of maltrin 700 and introduced into a predetermined volume of the stock solution . a separate 0 . 0203 g sample of a supra activated charcoal was introduced into a second separate sample of the same stock solution . in a third separate sample of the stock solution , 0 . 0203 g of a supra activated charcoal and 0 . 0779 g of maltrin 700 combined and compressed into a tableted wafer form was introduced after the wafer had been sufficiently crushed . the comparative adsorption results obtained are shown in table 4 . table 4______________________________________ percent salicylate relativetest substance adsorbed

charcoal and maltrin700 in tableted waferform______________________________________ as the results in table 4 show , maltrin 700 , when simply blended with a supra powder interfered with the activated charcoal &# 39 ; s adsorptivity by approximately 11 %. more importantly , the maltrin 700 , when thoroughly blended and tightly compressed with the a supra activated charcoal powder as it would be in the tableted wafer form of the subject decontaminant food product , interfered by more than an alarming 30 %. maltrin 700 was eliminated as a preferable component composition on this basis , as were numerous other possible compositions . among the many prototype wafer formulations tested was that for which the component compositions and their proportional quantities are shown in table 5 . equilibrium adsorption tests conducted for this prototype wafer formulation yielded adsorptivity measures that were significantly less than expected . interference tests were conducted for each of the components outside of activated charcoal to isolate the cause of the reduced adsorptivity . those tests indicated that the reduction in adsorptivity was due primarily to the inordinate levels of interference attributable to the melted chocolate and the emulsifier composition used in the formulation commercially marketed as dur - lo . for comparison purposes , prototype wafers were formulated , as shown respectively in tables 6 and 7 , first without the melted chocolate composition , then without either of the melted chocolate and the dur - lo emulsifier compositions . equilibrium adsorption tests were then performed for each prototype formulation . the isotherms for these prototype wafer formulations ( of table 5 , table 6 , and table 7 ) are shown in fig2 as curves 100 , 110 , and 120 , respectively . the melted chocolate component in table 5 was replaced for the table 6 and 7 prototypes with a cocoa powder composition , as a chocolate flavor is a desirable characteristic of the resulting wafer , regardless of the formulation used . table 5______________________________________component composition quantity ( g ) ______________________________________granulated sugar 0

025______________________________________ referring to fig2 isotherm 110 ( corresponding to table 6 ) clearly shows that the absence of melted chocolate but with the use of dur - lo affords a significant increase in the adsorptivity observed when taken with respect to isotherm 100 ( corresponding to table 5 ). isotherm 120 without dur - lo and melted chocolate shows , further , that the absence of both melted chocolate and the dur - lo emulsifier in the tested wafer affords an even greater increase in the observed adsorptivity over that of isotherm 100 . it is not readily apparent why this marked increase in interference is attributable to the melted chocolate and dur - lo emulsifier compositions in such an inordinate measure relative to the levels of interference attributable to the other component compositions . whatever the specific cause , it is likely that the unique physical properties of the melted chocolate and dur - lo components in some measure cause them to bind with the activated charcoal particles , filling many of the pores that otherwise would give each activated charcoal particle a greater internal surface area . the adsorptivity of the given activated charcoal particle is thus severely curtailed . referring now to fig3 there is shown a preferred method for forming the decontaminant food product of the present invention , in its preferred cookie sandwich form . appropriate quantities of the base wafer ingredients in the approximate weight percentage ranges of table 1 : activated charcoal 210 , corn syrup solids 211 , di - pac 212 , chocolate cream flavor 213 , vanilla dry flavor 214 , and sweetener 215 , are evenly blended at step 220 into a paste . as necessary , a limited quantity of water 216 is mixed into the paste to facilitate the malleability of the paste and thereby enhance the homogeneity obtained in the blend . after sufficient blending , the paste is allowed to dry at step 230 , at room temperature approximating 70 ° f ., for approximately 12 hours resulting in a dry paste composition . the dried paste 240 is then ground at step 250 in a wiley mill , employing preferably a 20 or 40 mesh screen . the ground preparation is then compressed at step 260 in , preferably , a one inch punch and die assembly set to impart at least 15 , 000 psi compression pressure when a 1 . 0 &# 34 ; diameter wafer is compressed and may be set at 40 , 000 psi compression pressure when a larger wafer in the order of 1 . 75 &# 34 ; diameter is used . a plurality of wafers are formed by the aforementioned steps . the wafer may then be sprayed with an anti - dusting spray film in step 262 in order to cover the activated charcoal particulates in order to minimize the smearing of the activated charcoal when being grasped by a user . the spray film is a sugar film formed of sucrose or dextrose or some like composition to form an encapsulation . the filling is then prepared by mixing and evenly blending at step 280 appropriate quantities of powdered sugar 270 , preferably having a 6x granularity , high fructose corn syrup 271 , vanilla flavor 272 , and salt 273 . an appropriate quantity of the resulting creamy mixture is then placed between a pair of wafers to assemble at step 300 a cookie sandwich decontaminant food product . although this invention has been described in connection with specific forms and embodiment thereof , it will be appreciated that various modifications other than those discussed above may be resorted to without departing from the spirit or scope of the invention . for example , functionally equivalent elements may be substituted for those specifically shown and described , proportional quantities of the elements shown and described may be varied , and in the formation method steps described , particular steps may be reversed or interposed , all without departing from the spirit or scope of the invention as defined in the appended claims .
