The invention provides methods for making steviol glycosides, including RebM and glycosylation products that are minor products in stevia leaves, and provides enzymes, encoding polynucleotides, and host cells for use in these methods. The invention provides engineered enzymes and engineered host cells for producing steviol glycosylation products, such as RebM, at high purity and/or yield. The invention further provides methods of making products containing steviol glycosides, such as RebM, including food products, beverages, oral care products, sweeteners, and flavoring products.

This disclosure provides aqueous steviol glycoside compositions as well as syrups and beverages comprising these compositions. In certain embodiments, the aqueous steviol glycoside composition comprises water and a sweetening composition, wherein the sweetening composition is solubilized in the water and comprises a stevioside composition and rebaudioside D.

The present invention relates to a food or beverage having enhanced sweetness exhibited by a sugar and a sweetener, a sweetening composition for producing the food or beverage, and a method for producing the food or beverage.

Provided is a method for preparing rebaudioside M by using an enzyme method. In the method, rebaudioside A or rebaudioside D is used as a substrate; and in the existence of a glucosyl donor, rebaudioside M is generated by means of reaction of the substrate under the catalysis of UDP-glucosyl transferase and/or recombinant cells containing the UDP-glucosyl transferase.

Glucosyl stevia compositions are prepared from steviol glycosides of Stevia rebaudiana Bertoni. The glucosylation was performed by cyclodextrin glucanotransferase using the starch as source of glucose residues. The short-chain glucosyl stevia compositions were purified to >95% content of total steviol glycosides. The compositions can be used as sweetness enhancers, flavor enhancers and sweeteners in foods, beverages, cosmetics and pharmaceuticals.

The present invention relates to a method for producing articles impregnated with at least one plant substance from at least one plant, characterized in that it comprises the following steps: a) Extraction and/or pressing of at least one plant (V1), or at least one part of said plant, producing a liquid plant extract (E1) and a solid fibrous residue (R1), then b) Separation of said plant extract (E1) from said fibrous residue (R1), and c) Destructuring of said fibrous residue (R1), d) Production of a fibrous web or of an article made from the fibrous residue (R1) obtained in step c), and e) Impregnation of said fibrous residue (R1) with (i) at least said plant extract (E1), which is optionally concentrated, purified, flavored and/or fragranced, with (ii) at least one water-soluble or liposoluble plant substance isolated from said plant extract (E1), with (iii) at least one composition comprising at least one optionally concentrated, purified, flavored and/or fragranced water-soluble or liposoluble substance of said plant extract (E1), or with (iv) at least one plant extract (E2) or at least one composition comprising at least one optionally concentrated, purified, flavored and/or fragranced water-soluble or liposoluble substance of said plant extract (E2), resulting from an extraction or pressing of a plant (V2) different from said plant (V1).

Consumables comprising a sweetener and at least one compound of the formulae described are provided herein, wherein the sweetener comprises a sweetening amount of rebaudioside M and/or a sweetening amount of at least one mogroside. The at least one compound of the formulae described herein enhances the sweetness of the consumable and/or modulates one or more taste attributes to make the consumable taste more like a sucrose-sweetened consumable. Methods of enhancing the sweetness of a consumable, methods of making a consumable taste more like a sucrose-sweetened consumable and methods of preparing consumables are also detailed herein.

The invention describes stevia compositions that are devoid of or have minimal concentrations of rebaudioside C and/or dulcoside A to decrease the aftertaste associated with stevia compositions.

The present application relates to a technique for extracting mogroside V. Provided is a method for extracting high-purity mogroside V from Siraitia grosvenorii. The specific steps comprise: pre-treatment of a raw material, extraction, centrifugation, enzymolysis, ultrafiltration, nanofiltration, decolorization, concentration, microwave drying, and pulverization. The invention utilizes a membrane-based technique for separation and purification, and only uses pure water as a solvent to eliminate usage of an organic solvent. The method can be easily performed, has a simple process, and provides a safe, environment-friendly, high quality, and low-cost product. The method can be used to realize continuous large-scale industrial production.

Steviol glycosides compositions are prepared from Stevia rebaudiana extracts. The compositions are able to provide a superior taste profile and can be used as sweeteners, sweetness enhancers, flavors, and flavor enhancers in foods, beverages, cosmetics and pharmaceuticals.
