Abstract:An efficient procedure for the lipase-catalyzed synthesis of Starch Ferulate has been established in non-aqueous system. Corn starch was used as the acyl acceptor and ethyl ferulate was used as the acyl donor. The trans-esterification of starch with ethyl ferulate was carried out in a few kinds of solvent at different temperatures and different times. The amount of lipase and the ratio of starch to ethyl ferulate also had been studied. The maximum degree of substitution of Starch Ferulate 0.031 was obtained by the presented method under the optimum reaction conditions: Novozym435 lipase as catalyst, isooctane as reaction medium, molar ratio of ethyl ferulate to starch was 3:1, amount of Lipase was 10%, 65 ℃ for18 h. The structure of Starch Ferulate was analyzed by FT-IR and 1H NMB.
