摘　　要：以野生火棘果渣为原料,采用酸水解法提取其中的果胶,通过正交试验得到最佳提取条件。试验结果表明,酸水解法提取野生火棘果果胶的最佳提取条件是:料液比1:9,提取温度90℃,提取时间60min,pH2,提取2次。在此条件下果胶产率为7.23%。采用活性炭作脱色剂,通过研究得到最佳脱色条件:活性炭用量1.0g/100mL,脱色时间15min,脱色温度65℃。The pectin in Pyracantha fortuneana residue was extracted with acid hydrolysis method.The optimal extraction condition was obtained by orthogonal test L9 （34）.The results showed that the optimal conditions of acid hydrolysis were：pH 2 hydrochloric acid at 90 ℃ for 60 minutes,twice of extraction with solid-liquid ratio 1：9 and its yield was 7.23%.The active carbons were used for the pectin decoloration.The optimal decoloring conditions were：1.0 g active carbon per 100 mL extract and treat 15min at 65 ℃.
