Methods for purifying steviol glycosides, including Rebaudioside X, are provided herein. Sweetener and sweetened containing Rebaudioside X are also provided herein. Methods of improving the flavor and/or temporal profile of sweetenable compositions, such as beverages, are also provided.

A food or beverage product is provided comprising a steviol glycoside composition, said composition comprising 5-30 wt % rebaudioside M (reb M), 15-35 wt % rebaudioside AM (reb AM), and 10-25 wt % rebaudioside N2 (reb N2) based on the total amount of steviol glycosides in the product, wherein the steviol glycoside composition is present in an amount below its sweetness threshold. It is found that the food or beverage product has a modified or enhanced flavor compared to a food or beverage product not comprising the steviol glycoside composition.

Methods of preparing highly purified steviol glycosides are described. The methods include utilizing enzyme preparations and recombinant microorganisms for converting various starting compositions to target steviol glycosides. The highly purified steviol glycosides are useful as non-caloric sweetener, flavor enhancer, sweetness enhancer, flavor stabilizer, flavoring with modifying properties (FMP), foaming suppressor and solubility enhancing agent in consumable products such as any food, beverages, pharmaceutical compositions, tobacco products, nutraceutical compositions, and oral hygiene compositions.

A method for making a granulated Stevia sweetener is described. The resulting sweetener has a desirably high solubility level.

A method is described for purifying Rebaudioside X using a plurality of adsorbent columns packed with an adsorbent resin, passing a solution containing Rebaudioside X through the columns to adsorb Rebaudioside X onto the adsorbent resin, and eluting the Rebaudioside X from the adsorbent resin to result in purified Rebaudioside X.

Glucosylated chlorogenic acid (GCGA) compounds, particularly compounds selected from those having structural formulae (A), (B), (C), (D), (E), (F), salts thereof, and combinations thereof, and methods of preparing same are described. The GCGA compounds are useful in beverage products, food products, and home care products.

Methods for purifying steviol glycosides, including Rebaudioside X, are provided herein. Sweetener and sweetened containing Rebaudioside X are also provided herein. Methods of improving the flavor and/or temporal profile of sweetenable compositions, such as beverages, are also provided.

Rebaudioside M compositions with improved aqueous solubility and methods for preparing the same are provided herein. The rebaudioside M compositions include (i) disordered crystalline compositions comprising rebaudioside M and rebaudioside D, (ii) spray-dried compositions comprising rebaudioside M, rebaudioside D and steviol glycoside mixtures and/or rebaudioside B and/or NSF-02, (iii) spray-dried compositions comprising rebaudioside M, rebaudioside D and at least one surfactant, polymer, saponin, carbohydrate, polyol, preservative or a combination thereof. Sweetened compositions, such a beverages, containing the rebaudioside M compositions with improved water solubility are also provided herein.

The present invention provides a process for preparation of highly purified mogrosides mixture from low purity mogrosides mixture. The process comprises providing a mixture of low purity mogrosides, dissolving the low purity mogrosides mixture in water or an aqueous alcohol solution to form an initial solution of mogrosides, passing the initial solution through a column system, wherein the column system comprises a plurality of columns, and each column is packed with a sorbent having different affinities to impurities and mogrosides so that one or more columns retains more mogrosides than other columns, washing the columns to remove impurities with an acidic aqueous solution, a basic aqueous solution, and an aqueous alcoholic solution successively, eluting the columns with an aqueous alcohol solution that contains higher alcohol content than the aqueous alcohol solution used in the washing step, wherein the eluate from the columns with high content of mogrosides are combined, and drying the combined eluate to obtain high purity mogrosides with the content of the total mogrosides are more than 70% (w/w). The present invention also provides a sweetener mixture and product comprising high purity mogrosides.

A taste and flavor profile modifying composition is described. The composition includes a blend of glucosylated steviol glycosides and residual steviol glycosides which can modify the intensity of a taste and/or flavor in a food or beverage product.
