磷脂改性现状

该文简要介绍磷脂基本加工过程和化学改性方法,着重介绍磷脂酶改性及其工业化生产现状,用于磷脂改性的酶主要包括磷脂酶和脂肪酶。在工业化设计时,除考虑反应基本参数,如酶的种类、水分、溶剂等因素外,工艺方案确定也是一个关键问题;对几种反应器进行比较,填充床反应器被认为是最适于大规模工业化生产,溶血磷脂的酶法生产代表着酶技术在油脂行业中应用开始。

General Evaluation of Modified Lecithins

This work gives a brief introduction of the processing and chemical modification of lecithins. Highlights cover the enzymatic modification of phospholipids and general evaluation of the industrial production. The enzymes used to modify phospholipids, including phospholipase and lipase. When come to the industrial design, the bioreasctors and processes are critical issues as well as the fundamental reaction parameters, such as enzymes, water, and solvents, et al. Comparing to several bioreactors, packed bed reactors are selected for the most large-scale processes.
