摘要:

长链脂肪酸淀粉酯作为改性淀粉的一种重要类型具有广泛的应用前景。酶作为生物催化剂在非水相中可对淀粉和长链脂肪酸进行酯化,该反应具有底物选择性高、产物专一性强、条件温和、产物可生物降解等优点。本文从酶催化合成反应的机理、酶法催化长链脂肪酸淀粉酯的制备方法、取代度的测定方面进行综述。

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
