中文摘要: 优化腰果脂肪提取工艺。先对提取腰果脂肪的方法进行选择,然后在单因素试验的基础上,应用响应面法对腰果脂肪提取条件进行优化。结果表明,腰果脂肪提取工艺最优条件为料液比1∶27(g/mL),提取时间4.44h,温度60.60℃,提取溶剂为纯石油醚。腰果脂肪实际平均得率为47.76%,所得腰果脂肪提取回归模型高度显著(相关系数R2=0.984 7),拟合性好(修正后的相关系数R2Adj=0.965 0)。
Abstract:To optimize the extraction conditions of cashew nuts fat,chossing a method of fat extraction of cashew nuts firstly,then based on the single factor experiments,the response surface methodology(RSM)was employed to optimize the extraction conditions of cashew nuts fat.The optimum extraction conditions were as follow:solid-to-liquid(S/L)ratio of 1 ∶27(g/mL),extraction time of 4.44 h,extraction temperature of 60.60 ℃,and the solvent of petroleum ether.The yield of fat was 47.76%.The cashew nuts fat extraction regression model was highly significant(R2=0.984 7)and with good fitting(R2Adj=0.965 0).
