通过测定南方地区常用的花生油、玉米油、菜籽油、大豆油、葵花油、茶籽油、橄榄油等植物油以及地沟油和过期植物油的A3005（代表不饱和度）、A985（代表共轭脂肪酸含量）、A960＋ A985（代表反式脂肪酸含量）三个指标值，得到了合格植物油三个指标值设定范围。在此基础上，建立快速筛查不合格植物油（过期、添加低价油、添加地沟油）的方法，有效地提高了植物油的监控效率。利用该法筛查出的若干疑不合格油，通过脂肪酸构成法和11，12，13，17脂肪酸含量判定法等，均证实它们是掺杂油或过期油，几种检测方法的结合应用，可进一步推断植物油不合格的原因。

In the present study ,by measuring the A3 005 (representing unsaturation) ,A985 (representing conjugated fatty acids ) , A960 + A985 (representing trans‐fatty acid ) of southern common vegetable oils (peanut oil ,corn oil ,canola oil ,soybean oil ,sun‐flower oil ,tea seed oil and olive oil) ,“waste oil”and overdue vegetable oils ,the pass‐setting‐range of these three index values for the vegetable oils was obtained .On this basis ,a method for rapid screening unqualified vegetable oil (expired ,adding low‐cost oil ,adding “waste oil”) was established .The method effectively improved the monitoring efficiency of vegetable oil .With this method of screening a number of suspected substandard oils were proved unqualified by determination of fatty acid composi‐tion and 11 ,12 ,13 ,17 fatty acid content .Through the combination of several detection methods ,the causes for disqualification of vegetable oils can be further inferred .
