In triacylglycerols (TAGs), position differences of fatty acids on the glycerol skeleton produce various TAG isomers. These TAG isomers have different pathways of digestion, absorption, and utilization in infants, thereby affecting TAG nutritional properties of TAGs. Here, we review the progress of research on methods for detecting TAG isomers, and identify direction and thought for improving these methods, including novel chromatographic combinations, perfect algorithm, and improved equipment. The ensuing optimization of these methods is expected to provide robust guarantee for the gradual improvement of milk-derived TAG isomer detection, and is an important prerequisite for infant formula to mimic the structured lipids of human milk.
在三酰甘油（TAGs）中，脂肪酸在甘油骨架上的位置差异会产生各种TAG异构体。这些TAG异构体在婴儿体内具有不同的消化、吸收和利用途径，从而影响TAGs的TAG营养特性。在此，我们综述了TAG异构体检测方法的研究进展，并确定了改进这些方法的方向和思路，包括新型色谱组合、完善的算法和改进的设备。对这些方法的后续优化有望为逐步改进乳源性TAG异构体检测提供有力保障，并且是婴儿配方奶粉模拟人乳结构化脂质的重要前提。
