The invention provides a high throughput, high purity, high yield system and method of isolating and purifying rebaudioside A (“Reb A”), with acceptable water solubility for all commercial uses, from commercially available Stevia rebaudiana starting material. The invention also provides a means of maximizing yields of 99+% purity Reb A based on the attributes of a given batch of Stevia starting material. The Reb A produced by the invention is water soluble, devoid of bitterness heretofore associated with rebaudioside sweeteners, non-caloric, and suitable for use as a reagent and as an ingredient in orally consumed products, e.g., as a sweetener, flavor enhancer, and flavor modifier.

The invention disclosed relates to a method for the extraction of sweet glycosides from the Stevia rebaudiana Bertoni plant and recovery of individual rebaudioside A and stevioside. The extraction is developed in the presence of pectinase, and the extract is purified using cyclodextrin and bentonite. High purity rebaudioside A is obtained by crystallization and recrystallization from ethanol. High purity stevioside is prepared from the filtrate by purification with cyclodextrin, bentonit, and ion exchange resins. The enzymatic modification of the rebaudioside A, stevioside and the purified extract is carried out using the transferring enzymes derived from Thermoactinomyces vilgaris and Bacillus halophilus.

Highly purified Stevioside and Rebaudioside A were prepared from sweet glycoside extracts obtained from Stevia rebaudiana Bertoni leaves. The resulting sweeteners are suitable as non-calorie, non-cariogenic, non-bitter, non-lingering sweeteners, which may be advantageously applied in foods, beverages, and milk products.

A process for the production of steviosides from Stevia rebaudiana Bertoni includes extraction of comminuted plant material by directly injecting steam into the extractor followed by filtration to get aqueous extract and alkali treatment to remove unwanted compounds in the form of precipitate. The treated aqueous extracted was filtered and the filtrate was first treated with gel or macroporous strong acid cation exchange resin and then with gel or macroporous weak base anion exchange resin. The aqueous eluant containing steviosides was concentrated to obtain purified steviosides.

Sweeteners on the basis of a simultaneously transglucosylated sweet glycoside mixture of Stevia rebaudiana Bertoni are prepared. The transglycosylation was developed in the presence of starch under the action of cyclodextrin glucanotransferase. The remaining maltodextrins are transferred to the fructose-terminated oligosaccharides. The sweeteners are purified to not less than 98% content of sweet glycosides and derivatives. The preparations are almost non-caloric, non-cariogenic, non-bitter, non-lingering sweeteners, which may be advantageously applied in foods, beverages, cosmetics and milk products.

The invention provides methods of purifying Rebaudioside D from the Stevia rebaudiana Bertoni plant extract along with Rebaudioside A. The methods are useful for producing high purity Rebaudioside D and Rebaudioside A. The high purity Rebaudiosides are useful as non-caloric sweeteners in edible and chewable compositions such as any beverages, confectionaries, bakeries, cookies, chewing gums, and alike.

Sweeteners on the basis of a simultaneously transglucosylated sweet glycoside mixture of Stevia rebaudiana Bertoni are prepared. The transglucosylation was developed in the presence of starch under the action of cyclodextrin glucanotransferase. The remaining maltodextrins are transformed to the fructose-terminated oligosaccharides by the addition of sucrose. The sweeteners are purified to not less than 98% content of sweet glycosides and derivatives. The preparations are almost non-caloric, non-cariogenic, non-bitter, non-lingering sweeteners, which may be advantageously applied in foods, beverages, cosmetics and milk products.

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.
