响应面法优化麦麸膳食纤维提取条件
Response surface methodology for extraction optimization of dietary fiber from wheat bran
摘要
Abstract
In order to research the effects of the enzymatic and chemical method on the extraction of the dietary fiber from wheat bran,four parameters (i.e.enzyme concentration,enzyme digestion time,alkali concentration and alkali hydrolysis time) were identified to be main variables to analyze their effects on extraction efficiency of dietary fiber.Furthermore,on the basis of the single-factor experiment,the response surface test was designed and Design Expert software was used to make quadratic regression analysis to determine the optimal process conditions for preparing dietary fiber of wheat bran.The optimum extracting conditions for extracting dietary fiber from wheat bran were found as follows:mixed enzyme 1.5 ％,digestion time 45 min,alkali 4％,hydrolysis time 35 min.Under these conditions,the extraction yield of dietary fiber was up to 87.84％,which was very close to the theoretical prediction value(relative error was 0.02％).Results showed that the regression equation of this experiment had certain application value.关键词
