尿素包合法从葡萄籽油中富集高纯度亚油酸甲酯及包合Enrichment of high purity methyl linoleate from grape seed oil by urea adduction and characterization of adduction complexes物表征分析

尿素包合法从葡萄籽油中富集高纯度亚油酸甲酯及包合Enrichment of high purity methyl linoleate from grape seed oil by urea adduction and characterization of adduction complexes物表征分析

为提升葡萄籽的使用价值，以葡萄籽油为原料，采用尿素包合法富集高纯度亚油酸甲酯。研究了脂肪酸甲酯与尿素质量比、尿素与95%乙醇质量比、包合时间和包合温度对包合效果的影响，并采用傅里叶变换红外光谱（FTIR）、X射线衍射（XRD）和扫描电子显微镜（SEM）对空白尿素结晶物和包合固形物进行表征。结果表明：制备高纯度亚油酸甲酯的最佳工艺条件为脂肪酸甲酯与尿素质量比1∶ 2、尿素与95%乙醇质量比1∶ 4、包合温度5 ℃、包合时间10 h，在此条件下得到的亚油酸甲酯含量为94.83%，收率为40.41%；FTIR和XRD分析表明，尿素包合反应没有新的官能团生成，且脂肪酸甲酯的包合降低了尿素的结晶度；SE...
