目的：了解碳原子当量在食用植物油掺伪中的应用价值。方法采用气相色谱法和高效液相色谱法分别对8种常见食用植物油的碳原子当量42(ECN42)和44(ECN44)甘油三酸酯含量进行了计算和比较。结果花生油与菜籽油各指标较接近，大豆油、玉米油和葵花籽油各指标较接近，而高品质的橄榄油与山茶油各指标较接近。但橄榄油和山茶油的ECN42和ECN44值远低于高亚油酸的大豆油、玉米油等种籽油类，且差异具有显著性(P<0.05)；而山茶油与橄榄油之间，只有实际和理论甘油三酸酯含量最大差值(ΔECN42、ΔECN44)有显著性差异(P<0.001)。结论本文首次对国内市场中常见食用植物油的 ECN42和 ECN44甘油三酸酯含量进行检测和总结，此结果为进一步开展食用植物油掺伪鉴别研究奠定了基础。

ObjectiveTo evaluate the Equivalent carbon numbers’ value in adulteration of edible vegeta-ble oils.Methods The values of triacyglycerols with equivalent carbon number 42(ECN42) and 44(ECN44) for 8 edible vegetable oils were calculated and compared by gas chromatography and high performance liquid chromatography.Results Most parameters were similar between peanut and rapeseed oils, soybean, maize and sunflower oils, as well as high quality olive and camellia oils. While for olive and camellia oils, their ECN42 and ECN44 values were significantly lower(P<0.05) than those of high linoleic vegetable seed oils(soybean, corn,etc). But for camellia oils, onlyΔECN42 andΔECN44 were significantly different from olive oils. Conclusion In this paper, we firstly analyzed and summerized the values of triacyglycerols with ECN42 and ECN44 for edible vegetable oils in domestic market. The results will facilitate future adulterate authentication studies for these edible vegetable oils.
