it has been unexpectedly discovered that glucosylation of steviol glycosides beyond a certain number of glucose units effectively reduces sweetness . it has also been discovered that with the reduction of sweetness , the glucosylated steviol glycosides can contribute to the modification of flavor and sweetness profiles . therefore , while sweetness decreases with glucosylation , flavor modification increases . the steviol glycosides mixture provides a certain amount of sweetness , but the present invention shows that the glucosylated steviol glycosides ( hereinafter “ gsg ”) enhance the flavor and sweetness profile in a wide range of applications , such as those listed in , but not limited by , the categories shown below in table 2 . similar taste and flavor improvements were found in other categories of products , including , but not limited to , table top sweeteners , sauces and gravies , confectionery products , baked goods , cereals , snacks , and fruit and vegetable preparations . in the following examples , the percentages in the formulas refer to percentages by weight . to evaluate the iso - sweetness of steviol glycosides ( sg ) and glucosylated steviol glycosides ( gsg ), a series of samples were selected as shown below in table 3 . the gsg was produced by treating the raw materials , steviol glycosides extracted from the stevia plant , and starch extracted from tapioca , with a natural enzyme . the enzyme transfers glucose units from starch to the steviol glycosides . the enzyme used to facilitate this transfer is produced by means of fermentation using non - gmo ( non - genetically modified organism ) bacteria . fig2 is an illustration of an example of glucosylation . specifically , fig2 illustrates the single glucosylation ( g1 ) of a stevioside molecule . this process can yield multiple glucosylation ( g2 , g3 , etc .) of different steviol glycosides ( mainly stevioside and rebaudioside a ) present in stevia extract . to evaluate the sweetness potency of various concentrations of stevia products in aqueous solutions , aqueous solutions of sugar , stevioside , rebaudioside a ( reb a ), rebaudioside d ( reb d ), gsg - s ( contains mainly smaller gsgs with 1 or 2 glucose units added to sg ), gsg - m and gsg - l at various concentrations were prepared using bottled water . samples were evaluated by the judges at room temperature ( 70 - 72 ° f .). the judges were 11 panelists that have been previously qualified for their taste acuity and trained in the use of a sweetness intensity rating scale . the evaluations were done in duplicate using the same panelists so that a total of 22 values were generated for each average data point . prior to the conduct of the study , judges were trained with sugar solutions and the use of the ballot . samples were given to the judges sequentially and coded with triple digit numbers . the order of sample presentation was randomized to avoid order of presentation bias . a rest period of five minutes was provided between samples . water and unsalted crackers were provided in order to cleanse the palate . results were statistically analyzed to generate a standard error value for each solution as well as a confidence level at a 95 % level . by comparing the sweetness of each test ingredient to the sweetness of several sucrose solutions , the sweetness potency of different stevia ingredients was estimated as shown in fig3 . fig3 is a graph of the sweetness potency , or sucrose equivalent value ( sev ), of different stevia ingredients at a 5 % sugar sweetness level ( i . e . at a concentration equivalent to 5 % sucrose ). this figure shows the effect of glucosylation on the sev of steviol glycosides . as the number of glucose units on steviol glycosides increases , the sweetness increases from stevioside to reb a and then starts decreasing with additional glucose units . a mango - passion fruit flavored water formula was developed to evaluate the effect of different stevia ingredients on the sweetness and flavor profile of the beverage . a total of 9 - 10 panel members participated in this sensory test , where they assigned relative values to sweetness , onset of sweetness , mango fruit flavor , passion fruit flavor , acidity , overall taste , etc . table 4 shows the no - sugar added beverage formula that used mainly reb a , reb d , gsg - s , or gsg - l . the amount of each ingredient ( reb a : 150 ppm ; reb d : 165 ppm ; gsg - s : 190 ppm ; and gsg - l : 300 ppm ) was selected to have around 50 ppm of steviol in each formula . fig4 a - 4 b show the modification of flavor and sweetness profiles caused by glucosylation . the sweetness intensity decreased and sweet onset delayed with glucosylation . mango flavor was enhanced and the passion fruit flavor reduced with glucosylation . table 5 shows the same mango - passion fruit flavored beverage formula with 4 % sugar and stevia ingredients that contribute an additional 4 % sugar - equivalent sweetness . the formula used reb a , reb d , gsg - s , or gsg - l in the amount of 50 , 55 , 73 , and 200 ppm respectively as outlined in the formula below . as the number of glucose units increased more flavor modification ( whether enhancement or suppression ) was observed as shown in fig5 a - 5 b . fig5 a - 5 b show the effect of glucosylation of sg on the modification of flavor and sweetness profiles of a beverage sweetened with sugar and stevia ( sg ). the sweetness intensity decreased and sweet onset delayed with glucosylation . both mango and passion fruit flavors were somewhat suppressed with glucosylation . a key point is that gsg modified the flavor profile . in this and the following examples , the gsg may be any glucosyl steviol glycoside composition , such as , but not limited to , a combination of gsg - s , gsg - m , and gsg - l . to evaluate the flavor modification in a juice drink , a range of gsg concentrations ( 0 to 1000 ppm ) was used with a typical apple blueberry juice drink formula . the objective was to assess whether the addition of gsg has an effect on key flavor attributes in various beverage applications . specifically , the objective was to determine whether the flavor profile and overall acceptance of a control sample of apple blueberry juice ( containing no gsg ) differs from a 30 % reduced sugar test sample of the same beverage ( containing gsg ). after preliminary sensory tests , it was apparent that gsg modified the flavor and sweetness profile at all concentrations . the gsg concentration is preferably in the range of about 0 to 1000 ppm , more preferably in the range of about 50 to 750 ppm , and most preferably in the range of about 50 to 500 ppm . for detailed sensory tests , two samples were selected to test against the control sample . the methodology of the detailed sensory tests is set forth below in table 6 . the formulas of the control and test samples are set forth below in table 7 . in this study , twenty consumer panel members evaluated three samples of apple blueberry flavored juice drink for overall acceptance and attribute intensities of apple and berry flavors , onset of flavor , sweetness , and aftertaste ( includes tartness , bitterness and lingering sweet aftertaste intensity ). the three samples included a full sugar control sample containing no glucosyl steviol glycosides ( gsg ) and two test samples containing low ( 0 . 025 %) and high ( 0 . 05 %) levels of gsg . the objective of the test was to determine if the addition of glucosyl steviol glycosides affects the flavor profile of a juice drink . the results indicated : the test samples had significantly higher overall acceptability and more apple flavor intensity than the control sample ( at & gt ; 90 % confidence ). the sweetness intensity of the test sample with low gsg was not significantly different from the control . gsg enhances sweetness and flavor at high level of usage ( p = 0 . 047 ). there was no significant difference in aftertaste intensities between the test and control samples ( at 90 % confidence ). to evaluate the flavor modification in a carbonated soft drink , a range of gsg concentrations ( 0 to 1000 ppm ) was used with an orange -

like as well as promoted the vanilla flavor . to evaluate the flavor modification in snacks and cereal / nut products , a range of gsg concentration ( 0 to 0 . 5 %) was used with cinnamon flavored coated almonds sweetened with sugar and / or high fructose corn syrup ( hfcs ). though the test was conducted with full sugar coated nuts , the findings are also pertinent with all other coatings used for snacks , cereal , confectionery with different level of moisture and fat ( or no - fat ) and different flavors ( chocolate , cinnamon , hazelnut , maple , brown - sugar , strawberry , blueberry , mango , etc .) with different levels of sugar including no - sugar - added products . after preliminary sensory tests , it was apparent that gsg modified the flavor and sweetness profile at all concentrations . the gsg concentration is preferably in the range of about 0 to 0 . 5 %, more preferably in the range of about 0 . 05 to 0 . 4 %, and most preferably in the range of about 0 . 1 to 0 . 3 %. as an example , two coated almond snacks were prepared where the test sample had reduced sugar . gsg was added in the amount of 0 . 19 % to the test sample . the gsg provided the rounded sweetness and enhanced cinnamon flavor to the test sample . gsg may also be added to confectionery formulations in order modify the flavor of confectionery , such as , but not limited to , hard boiled candy , soft textured confectionery , and chocolates . to evaluate the sweetness detection of gsg , a series of samples was made with nsf - 02 ( natural sweet flavor # 2 ) in acidified water ( ph = 3 . 3 , ph was adjusted using citric acid ). nsf - 02 contains gsg and about 15 % to 20 % dextrin , and is available from purecircle , 915 harger road , suite 250 , oak brook , ill . 60523 , usa . aqueous solutions of nsf - 02 at various concentrations were prepared using bottled water that was acidified to a ph of about 3 . 5 . the ph was adjusted using 1 % citric acid solution within a narrow range . the concentrations of nsf - 02 ranged between 0 to 1000 ppm . samples were evaluated by the judges at room temperature ( 70 - 72 ° f .). the judges were 10 panelists that have been previously qualified for their taste acuity and trained in the use of a sweetness intensity rating scale . the evaluations were done in duplicate using the same panelists ( n = 20 ). prior to the conduct of the study , judges were presented with sugar controls prepared with the acidified water for the intensity rating on the ballot referencing 2 , 4 , 6 and 8 on the evaluation scale . these solutions were provided to the judges in order to refresh the judge &# 39 ; s memory with the intensity ratings . samples were given to the judges sequentially and coded with triple digit numbers . the order of sample presentation was randomized to avoid order of presentation bias . a rest period of five minutes was provided between samples . water and unsalted crackers were provided in order to cleanse the palate . the judges could not detect any sweetness below 150 ppm of nsf - 02 . the sweetness equivalence value ( sev ) of different solutions of nsf - 02 is shown in fig6 . similarly , to quantify the synergy between nsf - 02 and sugar at 8 % sucrose equivalent sweetness in acidified water ( about 3 . 5 ph ) at various sugar reduction levels , a sensory test was conducted . the ph was adjusted using 1 % citric acid solution within a narrow range . sugar was reduced by adding the required level of nsf - 02 to attain 8 % sugar equivalent sweetness . as shown in fig6 , the sensory evaluation shows that the addition of nsf - 02 contributes additional sweetness in the presence of sugar , even though at a lower level of nsf - 02 ( 0 to 150 ppm of nsf - 02 in acidified water , without sugar ), it did not contribute any detectable level of sweetness . the synergy between sugar and nsf - 02 is the difference in sev contribution of nsf - 02 with and without sugar . the nsf - 02 concentration is preferably greater than about 25 ppm , more preferably greater than about 100 ppm , and most preferably in the range of about 500 ppm to 1 , 000 ppm . accordingly , the present invention shows that gsg not only modifies flavor , but it can also enhance sweetness in the presence of other sweeteners . this enhancement of sweetness is caused by the synergy between gsg and other sweeteners . the objective of this experiment was to develop the same sweetness and mouthfeel of high fructose corn syrup ( hfcs ) 55 in water solution using an equal amount of hfcs 42 plus gsg . hfcs 55 contains a total of 77 % dry solid , and 55 % of the dry solid is fructose . hfcs 42 contains 71 % dry solid , and 42 % of the dry solid is fructose . the sweetness equivalence values ( sevs ) of hfcs 55 and hfcs 42 are 0 . 99 and 0 . 91 , respectively . to match a similar sweetness profile and mouthfeel of hfcs 55 , samples were tested including different amounts of gsg from 0 to 500 ppm and different biogums ( xanthan , gum arabic , cmc , guar , locust bean gum , pectin ), or polysaccharides ( maltodextrin , oligosaccharides , resistant maltodextrin ), or polyols . all combinations of gsg and bulking agent ( to aid mouthfeel ) provided the desired sweetness and mouthfeel that matched hfcs 55 . the gsg concentration is preferably in the range of about 0 to 500 ppm , more preferably in the range of about 25 to 300 ppm , and most preferably in the range of about 50 ppm to 200 ppm . however , the best solution was the combination of xanthan gum and gsg ( shown in table 16 ). a similar analysis was carried out in a lemon - lime csd application , which had a combination of gsg and xanthan gum to provide the similar sweetness and mouthfeel with hfcs 42 as found in the formulation with hfcs 55 . it was noticed that when xanthan gum was added together with gsg the mouth feel perception was improved as well as the overall flavor profile . the addition of gsg made the sample taste more like a sugar - based product . sensory analysis ( discrimination test ) was conducted to determine the difference between the beverage samples with hfcs 55 and hfcs 42 . a triangle test was conducted with 19 panelists . only 4 identified the correct sample , two of whom were guessing . the two that correctly identified the odd sample indicated the differences were due to the hfcs 42 being less acidic and more flavorful ; they both also mentioned that hfcs 55 was slightly less sweet than hfcs 42 . although the tests were conducted using high fructose corn syrups , the results are not limited to high fructose syrups made from corn . the results are also applicable to high fructose syrups made from other carbohydrate sources , such as , but not limited to , wheat , barley , tapioca , rice , and potatoes . gsg was tested with several natural ( reb a , sg95 and purecircle alpha derived from stevia extract ) and synthetic sweeteners ( sucralose , acesulfame - k , cyclamate and aspartame ) to investigate the synergy between gsg and high intensity sweeteners . while gsg modifies the flavor profile , it also shows a different degree of synergy with high intensity sweeteners . as an example , to estimate the synergy between gsg and stevia sweeteners , nsf - 02 ( gsg + dextrin ) was mixed with a required quantity of purecircle alpha or reb a 97 in acidic solution ( ph = 3 . 8 ) to attain 8 % sugar equivalent sweetness as shown in table 17 . alpha is a blend of selected steviol glycosides , as described in international patent application no . pct / us2012 / 024722 filed feb . 10 , 2012 , entitled “ stevia composition ,” and is available from purecircle , 915 harger road , suite 250 , oak brook , ill . 60523 , usa . reb a 97 is also available from purecircle . synergy was calculated as the reduction of stevia sweeteners ( alpha or reb a ) for the addition of different levels of nsf - 02 as shown fig7 . it was discovered that alpha shows enhanced sweetness in the presence of a very small amount of nsf - 02 ( 25 ppm or less ), whereas more than 100 ppm nsf - 02 had to be added to attain any synergy with reb a as shown in fig7 . note that the detection level of nsf - 02 is around 150 ppm as shown in fig6 . in a solution with alpha , the nsf - 02 concentration is preferably greater than about 10 ppm , more preferably greater than about 25 ppm , and most preferably greater than about 100 ppm . in a solution with reb a , the nsf - 02 concentration is preferably greater than about 100 ppm , more preferably greater than about 150 ppm , and most preferably greater than about 200 ppm . gsg works with sugar , hfcs and other natural sweeteners to provide a better mouthfeel and sweetness profile in beverages . erythritol is used with stevia in beverages to provide some sweetness , but mainly to contribute mouthfeel that is lacking when a high amount of sugar is replaced with high intensity sweetener . a study was conducted to investigate the amount of erythritol that can be replaced with gsg in still beverages . a number of acidified beverage samples were targeted to 8 brix sweetness level with 200 ppm of reb a and the combination of erythritol and gsg as shown in table 18 . 1 . in a comparison of e , e6 and e7 samples , e6 was found to be very close to control ( e ) on flavor and overall mouthfeel , and slightly less sweet than control . e7 was very watery . 2 . a triangle test with e and e6 samples was conducted over two days with a total of 12 panel members . five of them detected the correct sample . the conclusion was that panel members could detect the difference ; thus the test failed . 3 . a preliminary test with e , e8 , e9 was then conducted , a triangle test with e and e9 was run . three out of ten panel members could identify the correct sample . gsg can reduce erythritol usage by 20 - 30 % ( from 3 . 5 % to 2 . 75 - 3 %) in beverages without any sacrifice of taste or mouthfeel . in the flavor system studied , the gsg concentration is preferably greater than about 10 ppm , more preferably greater than about 20 ppm , and most preferably in the range of about 30 ppm to about 200 ppm . in some flavor systems , gsg may replace more erythritol to provide a balanced , rounded sweetness flavor . although the present invention and its advantages have been described in detail , it should be understood that various changes , substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims . moreover , the scope of the present application is not intended to be limited to the particular embodiments of the invention described in the specification . as one of ordinary skill in the art will readily appreciate from the disclosure of the present invention , the compositions , devices , processes , methods , and steps , presently existing or later to be developed that perform substantially the same function or achieve substantially the same result as the corresponding embodiments described herein may be utilized according to the present invention .
