US Patent:

20120289687, Nov 15, 2012

Filed:

Jan 27, 2011

Appl. No.:

13/575751

Inventors:

Aron Broman Erickson - Albertville MN, US
John Joseph Hahn - Maple Grove MN, US
Allan S. Myerson - Chicago IL, US
Andrew Keith Ohmes - Jordan MN, US
Troy Allen Rhonemus - Plymouth MN, US
Kern M. Storo - Burnsville MN, US
Christopher Austin Tyler - Minnetonka MN, US

Assignee:

CARGILL, INCORPORATED - Wayzata MN

International Classification:

C07H 1/06

US Classification:

536 181

Abstract:

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 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.

Assignee:

CARGILL, INCORPORATED - Wayzata MN

International Classification:

C07H 15/24

US Classification:

536 181

Abstract:

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.

International Classification:

C07H 15/24
C07H 1/08

US Classification:

536 181

Abstract:

Disclosed are methods for the chromatographic separation of rebaudioside A from stevioside in glycoside solutions that are derived from stevia. The chromatographic separation may be an adsorb/desorb type of chromatographic separation or a fractionation type of chromatographic separation.

International Classification:

C07H 1/06
C07H 15/256
C07H 15/24
C07H 1/08

Abstract:

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.
