摘要
报道了以籽瓜瓜皮为原料提取果胶的工艺,通过正文实验[L9(33)]筛选出了提取及脱色的最佳条件是:在pH=2,温度85~90℃条件下提取60min效果最佳。还探讨了双氧水对果胶质量的影响,适宜条件是:15℃每100mL提取液加入6mL30%的双氧水,静置48h,即可获得色泽很好的果胶产品。
This article studies technological processes for extracting pectin from used seed watermelon and detemines the optimum conditions by orthogonal tests[L9(3^3].The exoerimental results show that optimum extacting conditions were: add 6% hydrogen peroxide(30Wt,%) into extract and settle for 48 hours,
