菊粉生物活性的研究进展

菊粉是一种不易被人体消化的碳水化合物,可从3600多种植物中提取。美国食品药品监督管理局批准菊粉用于提高食品的营养价值,因而菊粉已用于脂肪替代品、质地调节剂和功能性食品的开发。菊粉具有益生元特性,即促进双歧杆菌和乳酸杆菌等有益菌增殖,同时对宿主基因、肠道局部和全身代谢产生影响。目前研究发现菊粉在养生保健和治疗疾病方面具有多种生物活性,已经开发有相关的人类保健食品和动物饲料添加剂产品。本研究综述了菊粉抗氧化、抗疲劳、延缓衰老、降低炎症、刺激免疫应答、改善糖脂代谢紊乱等生物活性以及作用机制,提出现有研究的不足,并对菊粉未来研究方向进行了展望,为更深入地研究菊粉生物活性提供思路,为菊粉后续开发和利用提供理论依据。

Research progress on biological activities of inulin

Inulin is a carbohydrate that is not easily digested by the human body and can be extracted from more than 3600 plants. The United States Food and Drug Administration approved inulin to improve the nutritional value of food, so inulin has been used in the development of fat substitutes, texture regulators, and functional foods. Inulin has prebiotic characteristics, that is, it can promote the multiplication of bifidobacteria and lactobacillus, and it can also affect the host gene, local and systemic metabolism. At present, research has found that inulin has a variety of biological activities in health care and disease treatment, and relevant human health food and animal feed additive products have been developed. This study further summarizes the antioxidant, anti-aging, anti-fatigue, immune regulation, and other activities of inulin, and analyzes the product development of inulin in new healthy food and feed additives, to provide a new way to further study the biological activity of inulin and product deep processing and provide a deep theoretical basis for the subsequent development and utilization of inulin.
