乳制品中的脂质,作为最重要的生物过程中的关键组成部分,是提供给婴儿和成人的众多营养素之一。脂质的结构不仅错综复杂,而且多种多样,这使得整体和系统分析具有挑战性。近年来,脂质组学,作为脂质组学在组学时代的新推动者,已成为食品科学研究中发展最快的科学学科之一。此外,脂质组学也是近年来研究乳制品中脂质动态变化和化学组成的主要方法之一。这是分子间相互作用研究的一个相对较新的前沿,采用先进的液相色谱-质谱技术探讨脂类。在本文中,综述了基于液相色谱-质谱联用技术的脂质组学研究的最新进展,重点介绍了脂质组学和代谢性疾病风险在乳品研究中的应用。这包括常规脂质组学分析的详细工作流程,以及应用乳制品成分的例子,质量,安全,并揭示乳制品脂质的健康益处。先进有效的MS方法促进了肠道菌群和人体代谢性疾病风险的深入研究,为该领域的进一步研究提供了切实的解决方案。
Lipids in dairy products, as the crucial components in the most essential biological processes, were among the many nutrients delivered to the infants and adults. The structures of lipids are not only intricate but also varied, which makes the holistic and systematic analyses challenging. In recent years, lipidomics, as the new promoter of lipomics in the omics era, has become one of the fastest growing scientific disciplines in food science research. In addition, lipidomics is also one of the major methods to explore the dynamic changes and chemical compositions of lipids in dairy products in recent years. It is a relatively new frontier of intermolecular interactions research, using advanced liquid chromatography mass spectrometry technology to explore lipids. In this paper, the latest progress of liquid chromatography mass spectrometry based lipidomics was reviewed, with emphasis on the application of lipidomics and metabolic disease risk in dairy research. This includes a detailed workflow for routine lipidomics analysis, as well as examples of applications devoted dairy foods components, quality, safety, and revealing the health benefits of dairy products lipids. Advanced and effective methods of MS promote the in-depth study of gut microbiota and human metabolic disease risk and provide tangible solutions for further research in this field.
