摘要

Abstract

Modification process of glycosylation of zein by water-heating was preliminarily studied.Effects of different glycosyl donor,temperature,concentration of substrate on the conjugation degrees and the solubility and free amino of the conjugates were investigated.Results showed that under these conditions(temperature 90℃,weight ratio of protein to glucose 1:2) with glucose as glycosyl donor,conjugation degrees achieved 38.34% and content of soluble protein was 1.22mg/mL which rised 1.84 times than original zein.
