Extract dietary fiber from the soy pods by chemistry-enzymatic methods

摘要

The aim of this work was that pod as raw materials, study the effect of cellulase on extraction rate of soluble diet fiber(SDF) and insoluble diet fiber(IDF),and optimize the effects of the cellulase that included four sides: the time of cellulase action, the temperature of cellulase action, the pH of the cellulase and the rate of cellulase. As a result of the work maximum yield of SDF (6.72%) was obtained with the time of cellulase action of 72.83min, the temperature of cellulase action of 57.37°C,the pH of the cellulase 8.4 and the rate of cellulase of 0.33%.On the other hand the maximum of IDF(66.51%) was obtained with the time of cellulase action ofl 10.38min,the temperature of cellulase action of 65°C,the pH of the cellulase 8.8 and the rate of cellulase of 0.55%.
