绵羊奶组成和营养特性

The Composition and Nutrition Characteristics in Sheep Milk

绵羊奶是我国乳制品工业的"新增量",养殖规模和产奶量快速上升,然而,我国目前的绵羊奶产业水平还处于初级阶段,规模化加工制品几乎为零。绵羊奶营养价值高,总固形物在各种乳源中含量最高,除了具有较高含量的蛋白质、脂肪、矿物质和维生素以外,绵羊奶的活性功能因子丰富,乳铁蛋白、活性肽、乳脂肪球膜及低聚糖的组成、含量和生物活性与牛奶、山羊奶不尽相同。基于绵羊奶的组成和营养特性,开发功能性乳制品的市场前景广阔。本文综述绵羊奶的研究现状,重点剖析绵羊乳中生物学活性功能因子的组成特点,为绵羊奶的研究和产业化提供参考,以期推动我国绵羊奶的产业发展。

The sheep milk is the ’special industry’ of goat milk industry in China,and the breeding scale and milk production is rising rapidly.But,at present,the level of sheep milk industry in China is basically zero,and the field of sheep dairy product processing is still blank.Sheep milk has high nutritional value.The content of total solid is the highest among various milk sources.Sheep milk is characterized with high amounts of protein,fat,minerals and vitamins,and the composition and biological activity of sheep milk lactoferrin,active peptides,milk fat globule membranes and oligosaccharides are different with cow milk and goat milk.The development of functional dairy products based on the composition and nutritional characteristics of sheep milk has broad market prospects.In this article,the current research of sheep milk was reviewed,and its nutritional and bioactive composition were also focused on.This review can provide the scientific basis for the research and industrialization of sheep milk to guide and promote the development of sheep milk industry in China.
