中文摘要:
      采用超高效合相色谱串联四级杆飞行时间质谱(UPC2-Q-TOF-MS)技术分析了11种植物油的甘油三酯组成。这些植物油中,O-L-L为葵花籽油(22.27%±1.87%)、菜籽油(21.07%±1.76%)、玉米油(19.84%±1.35%)、米糠油(19.37%±0.87%)、芝麻油(17.55%±0.82%)中含量最高的甘油三酯;O-O-O在花生油(18.25%±0.69%)和橄榄油(39.37%±0.10%)中的含量最高;大豆油中含量最高的甘油三酯是L-L-L(22.16%±1.71%),亚麻籽油中是O-Ln-Ln(21.85%±0.18%),稻米油中是O-L-P(18.58%±1.02%),以及棕榈油中是O-P-P(25.05%±0.73%)。O-O-L与S-L-L等ECN值相同的甘油三酯实现了分离,且含量微少的甘油三酯组成也得到了鉴定。
英文摘要:
      The compositions of triglycerides in eleven kinds of vegetable oils were analyzed by ultra performance convergence chromatography with quadrupole time-of-flight mass spectrometry (UPC2-Q-TOF-MS). Among these vegetable oils, O-L-L contents were the highest in sunflower seed oil (22.27%±1.87%), rapeseed oil (21.07%±1.76%), corn oil (19.84%±1.35%), rice bran oil (19.37%±0.87%) and sesame oil (17.55%±0.82%), while O-O-O content was the highest in peanut oil (18.25%±0.69%) and olive oil (39.37%±0.10%). The triglyceride with the highest content in soybean oil, linseed oil, rice oil and palm oil were L-L-L (22.16%±1.71%), O-Ln-Ln(21.85%±0.18%), O-L-P (18.58%±1.02%) and O-P-P (25.05%±0.73%), respectively. Triglycerides with the same ECN value, such as O-O-L and S-L-L, were isolated. The contents of trace triglyceride were also identified.
