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.

The invention describes compositions that include a stevia sweetener and a salt of a steviol glycoside, wherein the concentration of the components provide an improved taste profile where bitterness, after taste and/or lingering of the stevia sweetener is decreased or eliminated.

Disclosed is a steviol glycoside referred to as rebaudioside D2. Rebaudioside D2 has five β-D-glucosyl units connected to the aglycone steviol. Also disclosed are methods for producing rebaudioside D2, a UDP-glycosyltransferase fusion enzyme, and methods for producing rebaudioside D and rebaudioside E.

The present invention relates to the novel use of saponins having acetyl residues on one of their sugar residues. These saponins are able to enhance the transfection efficiency to a surprisingly much higher extent than already known saponins and even than Lipofectamin.
