Novel steviol glycoside compounds characterized by a first group of four glucopyranose residues attached via the number 13 carbon (C13) of the steviol moiety and a second group of two or three glucopyranose residues attached via the number 19 carbon (C19) of the steviol moiety are described, and exemplified by compounds 1-4. These compounds can be present in a composition with other steviol glycosides (e.g., Reb D and Reb M) to enhance their solubilities. Accordingly, the novel compounds can facilitate the preparation of aqueous compositions having a higher concentration of steviol glycosides. A steviol glycoside composition including one or more of compounds 1-4 can be used as a sweetener composition to sweeten other compositions (sweetenable compositions) such as foods, beverages, medicines, oral hygiene compositions, nutraceuticals, and the like.
Compound 1, 2, 3, or 4 according to the following structures:
A method of enhancing the solubility of a steviol glycoside in an aqueous composition comprising a step of adding first and second steviol glycosides to an aqueous composition, wherein the first steviol glycoside has a branched chain of four glucose units attached to an atom of a cyclooctane group of a steviol moiety of the first steviol glycoside, wherein the second steviol glycoside is different than the first steviol glycoside, and wherein the second steviol glycoside has a solubility in an aqueous composition that lacks the first steviol glycoside that is lower than a solubility of the second steviol glycoside in an aqueous composition that includes the first steviol glycoside.
27-36. (canceled)
A method of enhancing the solubility of a steviol glycoside in an aqueous composition comprising a step of providing an aqueous composition comprising first and second steviol glycosides, wherein the second steviol glycoside is selected from the group consisting of rebaudioside A, rebaudioside B, rebaudioside M, rebaudioside D, rebaudioside I, rebaudioside Q, rebaudioside N, and stevioside, wherein the first steviol glycoside is different from the second steviol glycoside, and has an equal or higher molecular weight than rebaudioside M, and wherein the second steviol glycoside has a solubility in an aqueous composition that lacks the first steviol glycoside that is lower than a solubility of the second steviol glycoside in an aqueous composition that includes the first steviol glycoside.
