摘　　要：用盐酸提取八月瓜果皮的果胶,考察了p H值、提取时间和提取温度对果胶得率的影响。结果表明,p H值、温度对果胶得率有显著影响,八月瓜果皮果胶提取的最佳工艺条件为:p H=1,提取时间156 min,提取温度91℃,果胶得率为7.11%。With StauNtONia latifOlia as experimental raw material,extraction technology of pectin in StauN-tONia latifOlia pericarp was studied. Influence of pH,extraction time and extraction temperature on extrac-tion ratio of pectin were investigated by response surface methodology. Experimental results show that the best process condition of extraction ratio of pectin is 7. 11% at pH=1 and 91 ℃,extraction 156 min.
