  Enzymatic production and functional characterization of d-sorbitol monoesters with various fatty acids

  摘要：

  Sugar fatty acid esters are surfactants that are widely used in food, cosmetics, and pharmaceutical industries. In this study, enzymatic production of o-sorbitol monoesters with various fatty acids (C10-C18) was assessed. Reactions were performed in tert-butanol at 40 degrees C, catalyzed by Candida sp. 99-125 lipase. Dissolution of the substrates was found to be the limiting step of the reaction, and hence preheating was performed to increase the solubility of D-sorbitol. Thus, the yield of D-sorbitol palmitate was increased from 734 to 31.6 mM. The results demonstrated that the specific lipase preferred long-chain fatty acids. The surface-active properties. of the products were also determined. (C) 2015 Published by Elsevier B.V.
