| Abstract: | In order to make use of aloe peel discarded from processing of aloe stalk meat，aloe peel dry powder was as raw material，acid extraction and alcohol precipitation method was used for extraction of aloe pectin.On this basis，single factor test and response surface optimization experiment were carried out to extract pectin.Test showed that acid extraction and alcohol extraction of aloe pectin precipitation method was feasible.Optimum extraction technology was ratio of liquid to material 30∶1，the pH value of solution 3.5，the acid hydrolysis time 120 min and acidolysis temperature 75 ℃，and extraction rate of pectin was 22.593%. |
