β-葡聚糖的营养健康功能研究进展

Advances in Nutrition and Health Function ofβ-glucan

近年来,β-葡聚糖因其显著的生理学活性和健康特性,受到了各相关领域的广泛研究。β-葡聚糖存在于青稞、大麦、燕麦等天然植物及酵母、细菌、真菌等微生物中,是一种高营养价值的可再生多糖。因其来源广泛而具有的不同物理性质,也影响着β-葡聚糖在多种生物活性功能领域的开发应用。从不同来源的β-葡聚糖及构效关系入手,归纳了其在消化系统、神经系统、免疫系统等方面的研究现状,发现β-葡聚糖具有调控糖脂代谢紊乱、提高机体免疫力、改善脑功能、调节肠道菌群等特殊生理活性,可作为膳食补充剂与功能因子干预调节机体健康,在保健品研发等领域具有广阔的应用价值和前景,为β-葡聚糖的进一步开发利用提供理论参考和科学依据。

In recent years,β-glucan has been widely researched in various related fields due to its significant physiological activity and health characteristics.β-glucan exists in highland barley,barley,oats,and microorganisms such as yeast,bacteria fungi and other natural plants,and is a kind of renewable polysaccharide with high nutritional values.Different physical properties due to its extensive sources also affect the development and application ofβ-glucan in various bioactive functional fields.We have reviewed different sources ofβ-glucan and its structure-activity relationship,and summarized its research status in digestive system,nervous system,immune system and other aspects,indicating thatβ-glucan has special physiological activities such as regulating glucose and lipid metabolism disorders,improving immunity and brain function,regulating intestinal microenvironment.It can be used as a dietary supplement and functional factor to intervene and regulate body health,and also has broad application value and prospects in the field of health product research and development.This review will provide theoretical reference and scientific basis for the further development and utilization ofβ-glucan.
