Study on Acidolysis Extraction of Pectin from Chinese Water Chestnut Peel

Abstract:

In order to improve the value of Chinese water chestnut and to reduce the potential pollution,acidolysis extraction of Pectin from Chinese water chestnut peel was investigated in this study.Back-Propagation neural network was used to optimize the extraction process.And the optimum conditions listed as follows:hydrochloric acid concentration was 0.81 mol/L, temperature was 78℃,ratios solvent to material was 19.5:1(mL:g),extracting time was 1.53 h.Under the optimum conditions,the yield of pectin reached at 11.76%.
