Rebaudioside A and stevioside with improved solubilities
The invention describes sweetening compositions and methods to prepare sweetening compositions containing steviol glycosides, salts, and other natural or synthetic sweeteners with improved solubilities and sensory profiles.
1. A method for improving sensory profile of a steviol glycoside (SG) composition comprising rebaudioside A (RA), comprising:
introducing one or more salts and one or more non-SG sweeteners into the SG composition to produce a final product comprising:
RA in an amount between 70-85 wt % of the final product,
RB in an amount between 10-25 wt % of the final product,
the one or more salts in an amount between 0.1-5% wt. % of the final product, and
one or more non-SG sweeteners in an amount between 1-10 wt. % of the final product,
wherein the one or more salts are selected from the group consisting of a metal or metal alkali halide, a metal or metal alkali carbonate or bicarbonate, a metal or metal alkali sulfate or metabisulfate, and any combination thereof, and
wherein the one or more non-SG sweeteners are selected from the group consisting of sucrose, fructose, maltose, lactose, xylitol, sorbitol, dextrose, glucose, mannitol, aspartame, inulin, sucralose, acesulfame-K, sodium cyclamate, erythritol, thaumatin, arabinose, galactose, mannose, rhamnose, xylose, trehalose, raffinose, cellobiose, tagatose, allulose, mogroside, and any combination thereof.
2. The method of claim 1 , wherein the one or more salts are selected from the group consisting of sodium chloride, potassium chloride, magnesium chloride, sodium sulfate, magnesium sulfate, potassium sulfate, sodium carbonate, potassium carbonate, magnesium carbonate, sodium bicarbonate, potassium bicarbonate, calcium chloride and any combination thereof.
3. The method of claim 1 , wherein the one or more salts are selected from the group consisting of sodium chloride, potassium chloride, sodium carbonate, and any combination thereof.
4. The method of claim 1 , wherein the one or more non-SG sweeteners are selected from the group consisting of fructose, glucose and sucralose.
5. The method of claim 1 , wherein the final product comprises an additional SG in an amount less than about 2 wt %.
6. The method of claim 5 , wherein the additional SG is rebaudioside C, stevioside, or steviolbioside.
7. The method of claim 1 , wherein the final product has increased solubility compared to the SG composition.
8. The method of claim 1 , wherein the final product has an improved sensory profile compared to the SG composition.
9. The method of claim 1 , wherein the final product comprises one or more non-SG sweeteners in an amount between 1-5 wt. % of the final product.
10. The method of claim 1 , wherein the final product comprises one or more non-SG sweeteners in an amount between 5-10 wt. % of the final product.
11. The method of claim 1 , wherein the final product comprises:
RA in an amount between 70-80 wt % of the final product,
RB in an amount between 10-20 wt % of the final product,
the one or more salts in an amount between 0.1-5% wt. % of the final product, and
one or more non-SG sweeteners in an amount between 1-10 wt. % of the final product.
12. A method for improving sensory profile of a steviol glycoside (SG) composition comprising rebaudioside A (RA), comprising:
(a) adding rebaudioside B (RB) to the SG composition, hydrolyzing at least some of the RA in the SG composition to form RB, or both; and
(b) adding one or more salts and one or more non-SG sweeteners into the SG composition,
wherein the one or more salts are selected from the group consisting of a metal or metal alkali halide, a metal or metal alkali carbonate or bicarbonate, a metal or metal alkali sulfate or metabisulfate, and any combination thereof, and
wherein the one or more non-SG sweeteners are selected from the group consisting of sucrose, fructose, maltose, lactose, xylitol, sorbitol, dextrose, glucose, mannitol, aspartame, inulin, sucralose, acesulfame-K, sodium cyclamate, erythritol, thaumatin, arabinose, galactose, mannose, rhamnose, xylose, trehalose, raffinose, cellobiose, tagatose, allulose, mogroside, and any combination thereof,
wherein steps (a) and (b) are carried out so that a modified composition resulting thereof comprises:
RA in an amount between 70-85 wt % of the modified SG composition,
RB in an amount between 10-25 wt % of the modified SG composition,
the one or more salts in an amount between 0.1-5% wt. % of modified SG composition, and
the one or more non-SG sweeteners in an amount between 1-10 wt. % of the modified SG composition.
13. The method of claim 12 , wherein RB is added to the SG composition.
14. The method of claim 12 , wherein at least some of the RA in the SG composition is hydrolyzed to form RB by adding an alkali to the SG composition.
15. The method of claim 14 , wherein the alkali is sodium hydroxide.
