Abstract：Pectin from pumpkin(Cucurbita moschata)pulp was extracted using an acid hydrolysis method.A T single factor test was conducted by selecting three factors:acidity,extraction temperature and extraction time.Based on the results of single-factor test,the optimum conditions for extracting pectin from pumpkin pulp were obtained using an orthogonal test.The results showed that under the conditions of a pH value of 1.35,an extraction time of 55 minutes,and an extraction temperature of 95℃,the yield of pumpkin pulp pectin was 6.81％.The color,texture,dry weight loss and acid insoluble ash of pumpkin pulp pectin met national standards.
