| 摘 要： | 以米糠固脂为原料、甲醇钠为催化剂，在不同条件下进行自身酯交换，试样经甘三酯结构及熔点分析，结果表明，酯交换后的米糠固脂不但改变了原有脂肪酸在甘三酯位置的分布，而且熔点明显下降，产品达到米糠色拉油的冷冻试验要求.为了扩大米糠固脂的应用范围，又以米糖固脂和高熔点棕榈油为原料，用不同的比例进行酯交换，经分析酯交换产品可作为煎炸油应用.

| Abstract: | The transesterification of rice bran solid fat at various conditions with sodium methylate as a catalyst was studied in this paper.The samples were analyzed on the structures of triglycerides and melting points.The result of measurements has been expressed that rice bran solid fat which has been transesterificated has been changed on the positions of the former fatty acids distributed on the triglycerides,and the melting points were also decreased obviously.The product can meet the demand of refrigeration experiment.In order to extend the range of rice bran solid fat for other use,we performed a number of transesterification reactions with rice bran solid fat and palm oil which has high melting point at various ratios and conditions,The products of transesterification can be used as frying oil by analysis. |
