橙皮果胶的提取毕业论文

In this paper, the Orange had the advantage of the research, design a more reasonable process line, from the Orange have been extracted pectin. The use of orthogonal, the extraction of pectin and the pectin precipitation test conditions, come to the best of conditions. The results show that immobilized the most appropriate response to the PH value of , the optimum temperature to 60 ℃, while the original enzyme were PH and 55 ℃; The results also showed that the immobilized enzyme on the PH, temperature stability Than the original enzyme increased. This is immobilized to repeat the recovery of the use and storage of more favorable. Gelatin as a vector of fixed-pectinase study compared the amount of the vector, enzymes, produced by PH, the results show that under the conditions of PH Preparation of immobilized pectinase, to repeat the use of recovery after the 5th, activity may also retain more than 80%, immobilized pectinase is a better way.
