以燕麦为原料,采用逐层碾磨测定脂肪的方法,揭示出燕麦脂肪大部分存在于胚乳中,占到燕麦总脂肪的80%以上;通过对不同破碎粒度燕麦的脱脂效果测定,分析出中碎燕麦脱脂效果较好,并在此基础上采用乙醚、正己烷对物料进行浸出脱脂,分析出以正己烷为溶剂较乙醚效果好,在最佳工艺参数下,即料液比1:2. 5,时间6 h,温度60℃,脱脂燕麦残油率为0. 60%. 气相色谱分析表明,燕麦脂肪中不饱和脂肪酸的相对含量达到80. 04%,油酸、亚油酸含量分别为43. 40%和 34.70%

The method of layer - by - layer milling and then testing the fat content revealed that the oat fat mainly existed in endosperm. The fat in endosperm was more than 80% of the total oat fat. The test of defatting effects of different broken oat sizes showed that the material of mid - broken oat size had better effect in defatting. Ether and n - hexane were used to extract the fat from the material of mid - broken oat size, and the result was that n - hexane was better than ether. The optimal parameters of n - hexane extraction were as follows ：...
