油茶籽油甘三酯在优化条件下得到良好分离,在14种甘三酯中含量水平前三的分别为OOO + SLO(74. 21 % )、OOP( 10. 64% )和OOL + SLL( 5. 19% )。方差分析表明来自不同产地的油茶籽油甘三酯分布情况存在差异。油茶籽油在深层煎炸过程(180 ℃)中甘三酯的总体损失率为47. 85%,ECN_(40)、ECN_(42)、ECN_(44)、ECN_(46)、ECN_(48)和 ECN_(50)区的甘三酯损失率分别为86. 73% 、91. 52% 、75. 97%、45. 01% 和55. 30%。LLL和PPL历经40 h煎炸后完全降解。与深层煎炸油样相比,加热(180 ℃)样品中甘三酯的降解程度相对降低。偏相关分析表明油茶籽油甘三酯在深层煎炸过程中的降解速率与极性组分的生成速率呈...

The camellia oleosa seed oil triacylglycerol was separated completely under optimistic condition, in which OOO+SLO (74.21%), OOP (10.64%) and OOL+SLL (5.19%) were top three compounds among 14 triacylglycerol triacylglycerols. The analysis of variance showed that the difference happened to camellia oleosa seed oil triacylglycerols from different production areas. The overall loss ratio of camellia oleosa seed oil during deep frying (180℃) were 47.85%, and the loss ratio of triacylglycerols in each partition (ECN40, ECN42, ECN44, ECN46, ECN48 an...
