The invention relates to a method for the separation of two hydrophilic neutral oligosaccharides from each other with a chromatography on a bromine functionalized polystyrene cross-linked with divinylbenzene (BPS-DVB) stationary medium.

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, reb M2, and reb I 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.

Described herein is a method of adjusting the composition of a chromatography product to achieve a target enriched proportion of a desired component from an input feed having a lower proportion of the desired component using simulated moving bed (“SMB”) chromatography wherein the eluent for the SMB apparatus may comprise the very input feed being enriched. The method is exemplified by enriching a high fructose corn syrup from a 42% fructose syrup to a 55% fructose syrup without substantially reducing the dissolved solids concentration of the 55% syrup relative to the input 42% syrup. The 42% syrup is also used as the eluent for the SMB apparatus and may be reconstituted from the raffinate stream by passing the raffinate stream over a glucose isomerase column alone or in combination with a dextrose feed. The method reduces water usage and saves energy by minimizing the need for evaporation to obtain a 55% fructose syrup with a high dissolved solids content.

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

The present invention relates to the use of one or more glycosidases in the process for the production and/or purification of a produced desired oligosaccharide. The process is preferably a microbial fermentation process using a host microorganism, which may also comprise nucleic acids expressing sugar catabolic pathway proteins suitable for the degradation of saccharides otherwise hindering the purification of the desired oligosaccharide.
