摘　　要：以胡麻粕为试验材料,以胡麻胶得率为指标,在单因素试验基础上,应用响应面法优化胡麻胶的水浸提条件。结果表明,在试验范围内各因素对胡麻胶得率的影响程度从大到小依次为:浸提温度>p H>醇沉浓度>料液比。胡麻胶的最佳提取工艺为:浸提温度81℃, pH 3,醇沉浓度72%,料液比1︰27 (g/mL)。在该工艺条件下胡麻胶的得率达到7.602%。The extraction process of flaxseed gum from flaxseed flake was optimized by the response surface method on the basis of single factor tests. The results showed that the degree of influence of the yield of flaxseed gum in the test range of each factor from large to small was as follows: pH>extraction temperature>alcohol concentration>solid-liquid radio. The optimum extraction parameters of flaxseed gum were that the extraction temperature 81 ℃, pH 3, alcohol concentration 72%, and solid-liquid ratio 1︰27(g/m L). Under this condition, the yield of flaxseed gum was 7.602%.
