甘薯多糖的性质与开发利用

甘薯是我国主要的粮食作物之一，其不仅具有食用价值，还具有预防心脑血管疾病、糖尿病和降低癌症风险等药用价值。多糖是一类复杂的高分子碳水化合物，与蛋白质、核酸和脂类构成生命体的四大基本物质。甘薯多糖是由甘薯果实中分离出的一类有特殊生物活性的多糖，具有抗肿瘤、抗氧化、降血糖、调节免疫等生物活性。食用含甘薯多糖的制品有利于提高我国居民健康水平，然而目前，我国对于甘薯多糖的开发利用率不高，造成大量的功能性成分浪费，限制了甘薯多糖产业的发展。本文综述了近年来国内外甘薯多糖的性质及对其发展前景进行展望和提供理论依据。从而提高甘薯的综合利用价值，为我国未被充分利用的大量甘薯提供其他可发展利用的可能性。

Properties and exploitation of sweet potato polysaccharide

Sweet potato is one of the main food crops in China, which not only has edible value but also has medicinal value for preventing cardiovascular diseases, diabetes and reducing cancer risk. Polysaccharides are a type of complex high molecular carbohydrates, it is one of four basic substances composed of life with proteins, nucleic acids. Sweet potato polysaccharide is a kind of polysaccharide with special biological activity isolated from sweet potato fruit. It has biological activities such as anti-tumor, anti-oxidation, lowering blood sugar, and regulating immunity. It is benefit to eat products that containing sweet potato polysaccharides, and improve the basic health level of Chinese residents. However, development and utilization of sweet potato polysaccharides are poor at present, resulting in huge waste of functional ingredients, it leads to limited development of the sweet potato polysaccharide in industry. This article reviews the properties of sweet potato polysaccharides at home and abroad in recent years, also prospects application and provides a theoretical basis of sweet potato polysaccharides. It aims to improve the comprehensive utilization value of sweet potatoes, also provide other application possibilities for a large number of underutilized sweet potatoes in China.
