摘要:
The present invention provides methods to treat mixtures containing natural rebaudioside A (Reb A), rebaudioside B (Reb B), and rebaudioside D (Reb D), synthetic counterparts of these, and/or derivatives of the natural or synthetic embodiments obtain one or more of these glycosides in more pure form. In many embodiments, the invention can be used to process glycoside mixtures obtained at least in part from natural sources such as the Stevia plant. This allows, for instance, the recovery of a product including Reb A material in more pure form relative to Reb B material or Reb D material. As an alternative or in addition to recovery of the purified Reb A material, a product including Reb B material and/or Reb D material in more pure form relative to Reb A material can be obtained.

摘要:
A process for production of crystalline rebaudioside B from rebaudioside A is described. Additionally, four distinct crystal polymorphic forms of rebaudioside B are described, as well as methods for converting from one crystal polymorphic form of rebaudioside B to another crystal polymorphic form of rebaudioside B.
摘要:
The invention relates to the use of adsorb/desorb chromatography to prepare enriched compositions comprising rebaudioside B and/or rebaudioside D. Compositions with enriched rebaudioside-B and/or rebaudioside-D components may be prepared from Stevia-derived glycoside compositions using an adsorb-desorb chromatography process where the stationary phase of the chromatography bed comprises a macroporous neutral adsorbent resin.

摘要:
Disclosed are sweetener compositions comprising rebaudioside A and methods of making the sweetener compositions. The sweetener compositions comprise a highly soluble crystal form of rebaudioside A that displays, in some embodiments, a solubility at 24° C. in water of about 25 (grams rebaudioside A/per 100 grams water) or greater. The high solubility of the sweetener composition of the invention allows it to be used in applications such as syrups and concentrates.
摘要:
This disclosure pertains to a sweetener containing a high intensity sweetener and a taste modifying composition. In another aspect of the invention is a sweetener containing a high intensity sweetener, a taste modifying composition and a bulking material. Also disclosed are methods of making a sweetener of the present invention and methods of using the sweetener.
