采用气质联用（GC—MS）技术获取茶油、花生油、大豆油、菜籽油的纯油脂及茶油掺假后的油脂掺假模型的脂肪酸含量组成，在对脂肪酸含量变化进行分析的基础上，通过绘制以顺式油酸甲酯面积百分含量为x轴，花生酸甲酯面积百分含量为l，轴与茶油、大豆油、花生油、菜籽油油脂含量的等值线图，直观地呈现出茶油掺假油中茶油、花生油、大豆油、菜籽油的分布，可以定性且定量的鉴别茶油掺假油情况。研究结果可以为食用植物油脂的产品质量控制和掺假检测提供理论依据。

Based on the gas chromatography-mass spectrometry （GC-MS） technology, we obtained the Fatty acid content of the adulterate model of camellia oil. The model consists of peanut oil, soybean oil, rapeseed oil as a single grease and two kinds of oil adulterated into camellia oil. The content of fatty acids were analyzed and the contour map by the content of fatty acids and fat content were drew. Their can intuitively showing the distribution of each oil in the adulterated model.The research results of this paper were useful for the qua...
