Abstract
Official abstract text for this publication.
Methods of preparing highly purified steviol glycosides, particularly rebaudiosides A, D and M are described. The methods include utilizing recombinant microorganisms for converting various staring compositions to target steviol glycosides. In addition, novel steviol glycosides reb D2 and reb M2 are disclosed, as are methods of preparing the same. The highly purified rebaudiosides are useful as non-caloric sweetener in edible and chewable compositions such as any beverages, confectioneries, bakery products, cookies, and chewing gums.
First claim
Opening claim text (preview).
We claim: 1. A method for preparing reb D2 comprising: a. contacting a starting composition comprising reb A with UDP-glucosyltransferase, to produce a composition comprising reb D2; and b. isolating the composition comprising reb D2. 2. The method of claim 1 , further comprising purifying the composition comprising reb D2 to provide reb D2 having a purity greater than about 95% by weight on an anhydrous basis. 3. A method for preparing reb M2 comprising: a. contacting a starting composition comprising reb D2 with UDP-glucosyltransferase to produce a composition comprising reb M2; and b. isolating the composition comprising reb M2. 4. The method of claim 3 , further comprising purifying the composition comprising reb M2 to provide reb M2 having a purity greater than about 95% by weight on an anhydrous basis.
