[0001] This Application claims priority to US Provisional Patent Application Number 62/814734, filed March 6, 2019, which is incorporated herein in its entirety.

[0002] Disclosed herein are steviol glycoside compositions containing steviol glycoside blends that synergistically increase the solubility of rebaudioside D and rebaudioside M. These new compositions have a clean taste and may be used as sweeteners or sweetness enhancers in reduced sugar foods and beverages.

[0003] Steviol glycosides are a class of compounds that are capable of imparting a sweet taste to food and beverage products. These compounds are found in the leaves of Stevia rebaudiana (Bertoni), a perennial shrub that is native to certain regions of South America, e.g., Brazil and Paraguay, and they are characterized structurally by a common single base, steviol. Within the class of steviol glycoside molecules, species differ by the identity and number of carbohydrate residues at positions C13 and C19 of their base.

[0004] Researchers and food scientists are interested in steviol glycoside compounds because these compounds offer a potential solution to the problem of the increasing consumer demand for sweet foods and beverages that are non-caloric or are low caloric. However, these naturally occurring compounds cannot simply be substituted into products that contain glucose or other sugars. Among the challenges that one faces when using many steviol glycosides is the undesirable taste properties that they can impart, including one or more of a licorice taste, bitterness, astringency, sweet aftertaste, and bitter aftertaste.

[0005] Next generation steviol glycosides such as rebaudioside D (“Reb D”) and rebaudioside M (“Reb M”) offer better taste properties than the more commonly used steviol glycoside rebaudiosides, such as rebaudioside A (“Reb A”), offer. However, currently uses of Reb D and Reb M are limited due to their undesirably low solubilities.

[0006] The challenges of using Reb D and Reb M are particularly noticeable when one wishes to incorporate sweeteners that contain them into beverages. Beverage manufacturing processes often involve the production of an intermediate concentrated beverage syrup that is diluted with water to make a finished beverage. Typically, these processes require that the sweeteners that one uses stay dissolved in the concentrated beverage syrup for at least twenty-four hours. For example, many carbonated soft drink manufacturing processes involve the production of 5 + 1 throw syrup, which is then diluted with five times the volume of carbonated water to make a finished cola beverage. Additionally, because many beverages have a shelf life of from four weeks to one year, using a sweetener that has long term solubility is often desirable.

[0007] When used by itself and in common applications, Reb D has a water solubility of 350 - 400 ppm at 21°C. When Reb M is used by itself and in common

applications, it has a water solubility of 1300 - 1500 ppm at 21°C. By contrast, when Reb A is used by itself and in common applications, it has a water solubility of 4000 - 8000 ppm at 21°C.

[0008] Unfortunately, many beverages require a higher amount of Reb D than its aforementioned solubility would allow in order to replace a desirable amount, if not all, of the sugar typically found in e.g., colas. Similarly, concentrated cola syrup requires a higher amount of Reb M than its aforementioned solubility would allow for producing low sugar and no-sugar added beverages.

[0009] Known methods for improving solubility include spray drying, heating to certain temperatures for certain amounts of time, co-crystallizing, adding a stabilizer, and adding a solubilizing enhancer. However, these methods can be cumbersome and ineffective when trying to incorporate Reb D and Reb M into products in sufficient amounts to impart a desired taste and to remain soluble for a sufficient amount of time.

[0010] Thus, there is a need to develop sweetener compositions in which Reb D and Reb M each have sufficiently high solubility that these steviol glycosides can perceptively, effectively, and satisfactorily contribute to the total sweetness of the target end product. The steviol glycoside compositions described herein address this need.

[0011] Disclosed herein are steviol glycoside compositions and methods for making and using these compositions. Various embodiments of the steviol glycoside compositions described herein provide a high solubility sweetener composition that contains Reb D and Reb M and that can be used to create food, beverage, and other products without undesirable taste characteristics. [0012] One embodiment is directed to a dry blend of steviol glycosides comprising:

(a) Reb A, wherein the Reb A is 35-80% by weight of the dry blend; (b) Reb D, wherein the Reb D is 4-8% by weight of the dry blend; and (c) Reb M, wherein the Reb M is 15-22% by weight of the dry blend, wherein the steviol glycosides of the dry blend have a combined water solubility of at least 10,000 ppm at 21°C. In another embodiment, these dry blends may be used in the preparation of a food product, a beverage product, or other products in which one finds sweeteners.

[0013] Another embodiment is directed to a method for producing a high solubility sweetener composition comprising dry blending a set of steviol glycosides, wherein the set of steviol glycosides comprises Reb A, Reb D, and Reb M to form a dry blend, wherein none of the steviol glycosides nor the dry blend have been co-processed, freeze-dried or co-spray dried, the Reb D is 4-8% by weight of the dry blend, the Reb M is 15-22% by weight of the dry blend and the Reb A is 40-75% by weight of the dry blend, and the steviol glycosides of the dry blend have a combined water solubility of at least 10,000 ppm at 21°C.

[0014] Through various embodiments described herein, one may produce and use dry blends of sweeteners that impart desirable levels of sweetness and have desirable water solubility. These dry blends may be used as sweeteners in many applications, including but not limited to food products, confections, condiments, baked goods, tabletop sweetener compositions, beverages, and beverage products.

EXAMPLES

Example 1

Solubility Testing Methodology

[0046] Double column systems were used to determine the predictive versus actual concentration of comparative steviol glycoside formulations. Dry blend analyses (in this and all subsequent examples) were conducted using high-performance liquid chromatography, a variable wavelength detector @ 210 nm, and two columns in tandem, both of which were 250 mm x. 4.6 mm Phenomenex Synergi 4pm Hydro-RP

80A.

[0047] Measurements were taken weekly for a period of two weeks. Table I shows both the measured total solubility of steviol glycosides and the theoretical solubility.

[0048] Comparison Product A contains 56% Reb A and 40% Reb M.

[0049] Comparison Product B contains 37% Reb A and 60% Reb D.

[0050] Comparison Product C contains 28% Reb A, 45 % Reb D, and 24% Reb M.

[0051] This table shows that the testing methods for solubility that were employed are consistent with the predicted theoretical solubility, and that in these compositions high purity ingredients are additive in terms of solubility.

[0053] The normalized percentages of Reb A, Reb D, and Reb M were 73.8%, 6.4% and 19.8%, respectively. The solubility of DB lis significantly higher than the solubility of the products identified in Table I.

Example 3

Solubility of Dry Blends 2-4

[0054] Empirical solubility measurements of three dry blends according to the present invention were taken and are shown in Table III with a comparison to the theoretical solubility.

Table IV shows the composition of DB 2.

Table V shows the composition of DB 3.

Table VI shows the composition of DB 4.

Example 4

Solubility of Dry Blends 5-10

[0055] Table VII contains Reb A, Reb D, Reb M wt.% for dry blends 5 -10 and the observed system solubilities for all steviol glucosides.

[0056] The data in Table VII show the consistency of the increased solubility of dry blends of the present invention.

Example 5

Absence effect of other Steviol Glycosides

[0057] Four dry blends of the present invention were tested for water solubility. In these dry blends, the amount of each of the components other than Reb A, Reb D, and Reb M were varied. Table VIII shows that an increase in the other components did not affect solubility.

Table IX shows the composition of DB 11.

Table X shows the composition of DB 12.

Table XI shows the composition of DB 13.

Table XII shows the composition of DB 14.

[0058] Figure 1 shows a comparison of the components of data contained in Tables VIII to XII. All of the total solubilities are greater than 10,000 ppm. Additionally, the variation in amount of stevioside, Reb A and other steviol glycosides did not decrease solubility below 10,000 ppm.
