| 摘 要： | 以盐酸对小麦面筋蛋白的脱酰胺作用效果为参比,选取氯溶指数、脱酰胺程度为表征指标,利用SDS-PAGE、FTIR和SEM研究柠檬酸脱酰胺改性过程中小麦面筋蛋白分子构象和功能特性的内在关系.试验结果表明:在相同的脱酰氨程度下,柠檬酸脱酰胺改性明显改善小麦面筋蛋白的起泡性,其改性蛋白的起泡性是盐酸脱酰胺改性样品的4倍;当脱酰... |

| Abstract: | To study the effect of deamidation on wheat gluten with citric acid,wheat gluten deamidated with hydrochloric acid(HDWG) was selected as samples based on the evaluation from deamidation degree,nitrogen soluble index,SDS-PAGE,FTIR,and SEM of the modified samples.At the similar deamidation degree of 60%,foaming capacity of citric acid deamidated samples(CDWG) was about 4 times more than that of HDWG.CDWG exhibited the higher emulsification properties compared with HDWG.HDWG was observed to have the distinctiv... |
