Title: Study on preparation of soluble dietary fiber of sweet potato with cellulase
Abstract: To obtain the soluble dietary fiber of sweet potato,cellulase was used to modify the residues of sweet potato which was pretreated by amylase and protease before.The effects of cellulase amount,pH value,enzymolysis time and temperature on the yield of soluble dietary fiber were studied respectively.Based on the results,the orthogonal experiment was designed to obtain the optimum process conditions of extracting soluble dietary fiber.The optimum enzymolysis conditions were:cellulase addition amount 1.00%,pH4.8,enzymolysis temperature 50℃ and enzymolysis time 1.5h.The maximum yield of soluble dietary fiber reached 15.33%.After the enzymolysis,the water holding capacity of soluble dietary fiber increased 48.35%.
