利用油茶籽油及其他植物油在紫外波长200~360 nm间吸收光谱的差异性，通过判别分析和回归分析，对掺伪油茶籽油实现定性和定量检测。结果表明：通过判别分析建立的判别函数可以对掺伪油茶籽油的掺伪种类进行鉴别，准确率为100%；通过回归分析可对掺伪油茶籽油进行掺伪量的定量检测，掺杂菜籽油、大豆油和米糠油掺伪量的最佳检测范围为12%~100%，掺杂玉米油和棕榈油掺伪量的最佳检测范围为15%~100%。

Based on the differences in the UV absorption spectrum between 200 nm and 360 nm of oil-tea camellia seed oil and other vegetable oils,qualitative and quantitative detections of adulterated oil-tea camellia seed oil were carried out by discriminant analysis and regression analysis. The results showed that the adulteration types of adulterated oil-tea camellia seed oil could be identified using discriminant function established by discriminant analysis,and the accuracy rate was 100%;the adulteration amount of adulterated oil-tea camellia seed oil could be detected quantitatively by regression analysis;the optimal detection ranges of adulteration amounts of rapeseed oil,soybean oil and rice bran oil adulterated in oil-tea camellia seed oil were 12% -100%;and the optimal detection ranges of adulteration amounts of corn oil and palm oil adulterated in oil-tea camellia seed oil were 15% -100%.
