Compositions and methods using rebaudioside X to provide sweetness enhancement
Sweetened compositions comprising at least one sweetener and rebaudioside X are provided herein. Rebaudioside X is present in the sweetened compositions in a concentration at or below the sweetness recognition threshold, while the at least one sweetener is present in a concentration above its sweetness recognition threshold. Rebaudioside X acts to enhance the sweetness of the sweetened compositions, e.g. beverages and concentrate compositions, thereby allowing for preparation of sweetened compositions with reduced calorie content. Methods of enhancing the sweetness of a sweetened composition with rebaudioside X are also provided herein.
1. A beverage comprising a beverage matrix, at least one carbohydrate sweetener and rebaudioside X, wherein
the at least one carbohydrate sweetener is selected from the group consisting of sucrose and high fructose corn syrup, and the at least one carbohydrate sweetener is present in a concentration above its sweetness recognition threshold;
rebaudioside X has a purity from about 80% to about 99% and is present in a concentration from about 20 to about 30 ppm, and
rebaudioside X enhances the sweetness of the beverage by an amount more than the detectable sweetness of a solution containing the same concentration of rebaudioside X in the absence of the at least one carbohydrate sweetener and/or the rebaudioside X enhances the sweetness of the beverage by at least about 1.0 unit of sucrose equivalence on a percentage (w/v) basis.
2. The beverage of claim 1 , wherein rebaudioside X enhances the sweetness of the beverage by at least about 1.5 units of sucrose equivalence on a percentage (w/v) basis.
3. The beverage of claim 1 , wherein rebaudioside X enhances the sweetness of the beverage from at least 1.0 to about 3.0 units of sucrose equivalence on a percentage (w/v) basis.
4. The beverage of claim 1 , further comprising one or more functional ingredient selected from the group consisting of antioxidants, dietary fiber sources, fatty acids, vitamins, glucosamine, minerals, preservatives, hydration agents, probiotics, prebiotics, weight management agents, osteoporosis management agents, phytoestrogens, long chain primary aliphatic saturated alcohols, phytosterols and combinations thereof.
5. The beverage of claim 1 , further comprising one or more additives selected from the group consisting of carbohydrates, polyols, amino acids and their corresponding salts, poly-amino acids and their corresponding salts, sugar acids and their corresponding salts, nucleotides, organic acids, inorganic acids, organic salts including organic acid salts and organic base salts, inorganic salts, bitter compounds, flavorants and flavoring ingredients, astringent compounds, proteins or protein hydrolysates, emulsifiers, weighing agents, gums, antioxidants, colorants, flavonoids, alcohols, polymers, essential oils, anti-fungal agents and combinations thereof.
6. The beverage of claim 1 , wherein the rebaudioside X has a purity greater than about 95%.
7. The beverage of claim 1 , wherein the beverage is selected from a cola, lemon-lime flavored sparkling beverage, orange flavored sparkling beverage, grape flavored sparkling beverage, strawberry flavored sparkling beverage, pineapple flavored sparkling beverage, enhanced beverage with vitamins and/or minerals, ginger-ale, soft drink, root beer, malt beverage, fruit juice, fruit-flavored juice, juice drink, nectar, vegetable juice, vegetable-flavored juice, sports drink, energy drink, protein drink, enhanced water with vitamin, near water drink, coconut water, tea, coffee, cocoa drink, beverage containing milk components, beverage containing cereal extracts and smoothie.
