| Abstract: | Pectin was extracted from orange peel using tartaric acid aqueous as extraction system. The best technical conditions were obtained through orthogonal experiment, as follows： weight ratio of tartaric acid aqueous solution and orange peel was 25 ： 1, pH of extraction solution was 1.5, extraction temperature was 90 ℃, and extraction time was 90 min. Under the best conditions, the average yield rate of pectin was up to 17.08 %. |
