摘要
驼乳脂肪以脂肪球的形式存在,乳脂肪球膜(milk fat globule membrane,MFGM)是包裹在脂肪球外部的三层膜结构。这种具有生物活性功能的三层膜主要由蛋白质、酶、三酰基甘油和极性脂类(胆固醇、鞘脂等)组成。MFGM蛋白因其优异的生物活性功能和营养价值而受到广泛关注。笔者重点综述了驼乳MFGM蛋白的组成分布与核心功能特性,包括其抗菌、免疫调节、乳化稳定及肿瘤干预等作用;从蛋白质组学方面简述了驼乳与牛乳、羊乳等其他乳源的主要MFGM蛋白的组成及功能特性的差异;分析了不同加工工艺对驼乳MFGM蛋白的影响。深入解析驼乳MFGM蛋白的功能特性与差异机制,不仅有助于揭示驼乳的营养价值,且能为驼乳MFGM蛋白产品的开发提供理论基础。
Camel milk fat exists in the form of fat globules.The milk fat globule membrane(MFGM)is a three-layer membrane structure wrapped around the exterior of fat globules.This three-layer membrane with biologically active functions is mainly composed of proteins,enzymes,triacylglycerol and polar lipids(cholesterol,sphingolipids,etc.).MFGM protein has received extensive attention due to its excellent biological activity functions and nutritional value.The author mainly reviewed the composition distribution and core functional characteristics of MFGM protein in camel milk,including its antibacterial,immunomodulatory,emulsifying stabilizing and tumor intervention effects.And from the perspective of proteomics,the differences in the composition and functional characteristics of the main MFGM proteins between camel milk and other milk sources such as cow milk and goat milk were briefly described.The influence of different processing techniques on the MFGM protein in camel milk was analyzed.An in-depth analysis of the functional properties and differential mechanisms of camel milk MFGM proteins will not only help elucidate the nutritional value of camel milk but also provide a theoretical foundation for the development of camel milk MFGM protein-based products.
