湖南省自然科学基金重点项目“橡实淀粉主要理化功能特性的研究”；

本校为第一机构

采用曲线回归法、正交试验法和方差分析法等对橡实淀粉的漂白工艺进行了较为详细的研究.结果表明:各因素对橡实淀粉白度的影响程度大小依次为:H2O2浓度＞反应pH值＞反应时间＞淀粉乳浓度＞反应温度;漂白工艺的最佳条件为:液固比5:1、H2O2浓度1.0%、反应温度40℃、反应时间5h和反应pH值11.在此最佳工艺条件下,经漂白后橡实淀粉的白度均超过标准玉米淀粉的白度.

The bleaching technics has been studied by using curve estimation,orthogonal experiment,and analysis of variance.The results show that the influencing extent of various factors is H 2O 2 consistency,pH value,reaction time,starch emulsion consistency,and reaction temperature in turn.The optimum conditions for bleaching acorn starch obtained are as follows:water to starch 5∶1(v/w),H 2O 2 1.0%,40℃,pH 11,and reaction time 5h.On these conditions,the whiteness values of ...
