Progress on oxidation stability of Antarctic krill (Euphausia superba) oil

南极磷虾油是一种富含n-3多不饱和脂肪酸的功能性油脂。为提升南极磷虾油的氧化稳定性,首先简要介绍了影响南极磷虾油氧化稳定性的脂质组成要素,概括了不同加工方式对南极磷虾油氧化稳定性的影响,在此基础上详述以传统脂质氧化指标、微量成分含量变化、挥发性成分、脂质组学评估南极磷虾油氧化稳定性的现状。南极磷虾油的脂质劣变机制复杂,氧化状况评估困难,未来应筛选出合理化评估南极磷虾油氧化稳定性的方法,并系统研究其脂质组成与氧化稳定性之间的量效关系。

Antarctic krill oil is a functional oil rich in n-3 polyunsaturated fatty acids. In order to improve the oxidation stability of Antarctic krill oil, lipid composition elements influencing the oxidation stability of Antarctic krill oil were introduced firstly in brief, and then the effects of different processing methods on the oxidation stability of Antarctic krill oil were summarized. On this basis, the current situation of evaluating the oxidative stability of Antarctic krill oil by traditional lipid oxidation indexes, changes of trace component content, volatile components and lipidomics was described in detail. The lipid deterioration mechanism of Antarctic krill oil is complex and it is difficult to evaluate the oxidation status.In the future, a reasonable method to evaluate the oxidation stability of Antarctic krill oil should be screened out, and the dose-response relationship between its lipid composition and oxidation stability should be studied systematically.
