刺梨果渣膳食纤维提取改性及生物活性研究进展

Research progress of dietary fiber extraction modification and bioactivity of Rosa roxburghii Tratt pomace

刺梨主要分布于我国西南山区和丘陵地带,因刺梨富含多种氨基酸、碳水化合物、维生素、黄酮、多酚和膳食纤维,具有解毒、健胃消食和降低血糖血脂等生物活性,成为贵州省推动“精准扶贫”、实施“乡村振兴战略”的重要支柱产业之一。目前,刺梨主要以开发饮料为主。刺梨果渣是刺梨榨汁后的副产物,含有丰富的膳食纤维,是一种优质膳食纤维原料。膳食纤维素有“第七大营养素”之称,分为可溶性膳食纤维和不可溶性膳食纤维,两者均具有重要的生理功能。本文综述了国内外刺梨果渣膳食纤维的提取、改性及生物活性的研究进展,并对刺梨果渣膳食纤维提取改性研究中存在的问题及发展趋势进行总结展望,以期为刺梨果渣膳食纤维的利用提供理论依据。

Rosa roxburghii Tratt is mainly distributed in the mountainous and hilly areas of southwest China,because the Rosa roxburghii Tratt is rich in a variety of amino acids,carbohydrates,vitamins,flavonoids,polyphenols and dietary fiber,with detoxification,stomach strengthening and digestion,blood glucose and lipids reduction,and other biological activities,has become one of the important pillar industries in Guizhou Province to promote“targeted poverty alleviation”and implement the“rural revitalization strategy”.At present,the Rosa roxburghii Tratt is mainly to develop beverage.Rosa roxburghii Tratt pomace is the by-product of Rosa roxburghii Tratt juice extraction,rich in dietary fiber,is a high-quality dietary fiber raw materials.Dietary fiber has the name of“seventh major nutrient”,and is divided into soluble dietary fiber and insoluble dietary fiber,both of which have important physiological functions.This paper reviewed the progress of extraction,modification and bioactivity of Rosa roxburghii Tratt pomace dietary fiber at home and abroad,and summarized the problems and development trend of Rosa roxburghii Tratt pomace dietary fiber extraction and modification research,in order to provide theoretical basis for the utilization of Rosa roxburghii Tratt pomace dietary fiber.
