【Abstract】 In this article, we introduce a new technology which use ethanol dissolve edible pigment, and then extract pectin with hydrochloric acid deposit pectin with ethanol from dry orange waste. The best condition was obtained by L9(34) experiment, and the yield was determined by pectin yield and jelly untits, i.e. Pectin X Viscosity of Pection solution.The best condition was. pH1.5, Time 2h, temperature 80℃. Pectin yields 13.88%.更多还原
