摘要/Abstract

摘要： 本文对经湿热处理和原橡实淀粉的粘度、透光率、凝沉稳定性进行对比研究,研究表明:湿热处理的温度对淀粉粘度有极显著影响。不同的橡实淀粉粘度的影响差异明显;湿热处理会降低橡实淀粉的粘度,温度越高,粘度降低的幅度越大;湿热处理对淀粉的透光有一定的影响,在低温段的湿热处理对其透光率影响较少,在高温段影响较大,而且其透光率随处理的温度升高而迅速增加;湿热处理的温度对淀粉的凝沉稳定性有极显著影响,湿热处理的温度越高,淀粉的凝沉稳定性就越差。

关键词: 湿热处理, 橡实淀粉, 粘度, 透光率, 凝沉稳定性

Abstract: This paper discussed the results of the contrastive study among the viscosity, the translucent rate and retrogradation properties of acorn starch with respect to moist heat treatment. The results indicated: First, the temperature of moist heat treatment has very distinct effects on the viscosity of the starch, and it has different effects on different species acorn starches as well. Moist heat treatment can reduce the viscosity of acorn starch, so the higher the temperature, the more the viscosity will reduce. Second, moist heat treatment has some effects on the translucent rate of acorn starch. It has less effect on the acorn starch translucent rate in low temperature, but has great effect on the acorn starch translucentrate in high temperature. That is, the translucent rate, rapidly increases with the temperature rising. Thirdly, moist heat treatment has very significant effects on the retrogradation property of acorn starch. The higher the temperature, the worse the retrogradation property of acorn starch will be.

Key words: , moist heat treatment； acorn starches； viscosity； translucent rate； retrogradation property；
