Abstract: Masking compositions are provided comprising at least one unpleasant tasting amino acid other than arginine, protein hydrolysate and/or protein component wherein the taste Of the unpleasant tasting component is masked with the addition of sucralose to provide organoleptically acceptable compositions. Masking compositions in accordance with the invention may then be incorporated in beverages, foods, bars, or candies to provide nutrient products.

Abstract: An immobilized isozyme of Lipase MY or AY from Candida rugosa is used for stereoselectively hydrolyzing racemic mixtures of esters of 2-substituted acids, other than 2-halo propionic acids, transesterifying esters or acids or esterify acids or alcohols, at high enantiomeric excess, in an organic solvent. Immobilization of the isozyme may be carried out in the presence of an organic acid such as stearic acid. The immobilized isozyme may be used with a fatty acid or fatty acid ester that increases stereoselectivity or rate of hydrolysis of a mixture of racemic esters.
