| Summary: | The regioselective acylation of fructose with various fatty acids catalyzed by immobilized Upases from Mucor miehei and Candida antarctica in tert-butanol was investigated. The reaction parameters affecting the catalytic activity as well as the regioselectivity of the reaction, such as the nature and the concentration of the acyl-donor and the water activity (aw) of the system, were studied. Yields above 50 % of ester were obtained after 72h of incubation when the reaction was carried out with an excess of fatty acid. © 1998 Elsevier B.V. All rights reserved. |
