Yeast cell wall (YCW) polysaccharides, including β-glucans, mannans, chitins, and glycogens, can be extracted from the waste of beer industry. They are environmentally friendly, abundant, inexpensive raw materials, and have shown broad biological activities and application potentials. The exploitation of yeast polysaccharides is of great importance for environmental protection and resource utilization. This paper reviews the structural features and preparation of YCW polysaccharides. The solubility and emulsification of yeast polysaccharides and the properties of binding metal ions are presented. In addition, biological activities such as blood glucose and lipid lowering, immune regulation, antioxidant, promotion of intestinal health, and promotion of wound healing are proposed, highlighting the beneficial effects of yeast polysaccharides on human health. Through modification, the physical and chemical properties of yeast polysaccharides are changed, which emphasizes the promotion of their biological activities and properties. In addition, the food applications of yeast polysaccharides, including the food packaging film, emulsifier, thickening agent, and fat alternatives, are focused and discussed.
酵母细胞壁（YCW）多糖，包括β-葡聚糖、甘露聚糖、几丁质和糖原，可从啤酒工业的废料中提取。它们是环保、丰富、廉价的原材料，具有广泛的生物活性和应用潜力。酵母多糖的开发对于环境保护和资源利用具有重要意义。本文综述了 YCW 多糖的结构特征和制备方法。介绍了酵母多糖的溶解性和乳化性以及结合金属离子的特性。此外，还提出了降血糖、降血脂、免疫调节、抗氧化、促进肠道健康和促进伤口愈合等生物活性，突出了酵母多糖对人体健康的有益作用。通过修饰，可以改变酵母多糖的物理和化学性质，从而强调促进其生物活性和特性。此外，还重点讨论了酵母多糖在食品中的应用，包括食品包装膜、乳化剂、增稠剂和脂肪替代品。
