Study on extraction technology of orange peel pectin
Abstract：With orange peel as raw material was extracted with acid hydrolysis of pectin, the weight determined by extraction of pectin content of different factors on rate of pectin extraction, combined with orthogonal test to determine the optimum extraction conditions. The main conclusions: extracting pectin from citrus peel the optimum conditions for the solid to liquid ratio 1:20, temperature 70℃, pH1.5, time 90min, pectin extraction rate was 19.35%.
