摘　　要：研究了从菜籽粕中水提菜籽多糖的工艺。在单因素试验的基础上,以提取温度、提取时间与料液比为因素,以菜籽多糖得率为指标,采用响应面法优化菜籽多糖的提取工艺。结果表明:在提取温度80℃、提取时间3.4 h、料液比1∶34、提取1次的条件下,菜籽多糖得率为2.09%。The polysaccharides were extracted from rapeseed meal by water. On the basis of single factor experiment, the extraction of polysaccharides was optimized by response surface methodology with extrac- tion temperature, extraction time and ratio of solid to liquid as factors and polysaccharides yield as indica- tor. The results showed that under the conditions of extraction temperature 80 ℃, extraction time 3.4 h, ratio of solid to liquid 1 ： 34 and extraction times once, the polysaccharides yield was 2.09%.
