The technology for extracting insoluble dietary fiber from prickly ash seed by a enzymatic-chemical method was studied.On the basis of single factor tests,the Box-Behnken design test was used to study the effects of the concentration of NaOH,alkali extraction temperature,alkali extraction time,dosage of trypsin on the yield of insoluble dietary fiber(IDF).The results indicated that the obtained regression model represented the relationship between the independent variables and the responses well;the optimum... |
