Abstract:

Long-chain fatty acid starch esters, an important kind of modified starch products, have attractive application
prospects. It is well known that the application of non-aqueous enzymatic catalysis in esterification of starch with long-chain
fatty acids has the advantages of higher substrate selectivity, suppression of unwanted water-dependent side reactions, mild
reaction conditions and biodegradability. In this review, the reaction mechanism and the currently available methods for
lipase-catalyzed synthesis of starch esters with long-chain fatty acids in non-aqueous phase and the recent progress in the
determination of degree of substitution are discussed.

Key words: long-chain fatty acid starch esters, enzymatic catalysis, non-aqueous phase, degree of substitution
