摘要:

褐藻寡糖是一种功能性海洋寡糖,由褐藻胶经酶解得到,由β-1,4-甘露糖醛酸(M)和α-1,4-古洛糖醛酸(G)链接起来的不规则低分子聚合物。褐藻寡糖粘度较低、水溶性强;此外,它还具有抗氧化、免疫调节、抗细菌和炎症等多种生物学活性,在医学科学、功能食品、绿色农业等领域有着广泛的应用。虽然我们对褐藻寡糖的研究相对缺乏,但它作为一种新型生物饲料添加剂应用于畜牧业生产中,前景广阔。本文综述了褐藻胶的来源、褐藻寡糖的化学组成、制备方法与生物学活性,以及在畜禽上的应用,为后续褐藻寡糖的深入研究和未来在产业上的应用奠定基础。


Abstract: Alginate oligosaccharides (AOS), belonging to the class of functional marine oligosaccharides, are low-molecular polymers linked by β-1,4-mannuronic acid (M) and α-1,4-guluronic acid (G), which could be classically obtained by enzymatic hydrolysis of alginate. With low viscosity and good water solubility, as well as anti-oxidant, immune regulation, anti-bacterial and anti-inflammatory activities, AOS have been widely used in medical science and functional food, green agriculture and other fields. As new bio-feed additives, AOS have broad potential applications in animal husbandry. In this review, the sources of alginate, chemical structure and preparation methods of AOS, and their biological activities and application in livestock and poultry are summarized. We expect this review could contribute to lay a foundation of application and further research for AOS in livestock and poultry.
