摘　　要：膳食纤维被称为“第七大营养素”,具有调节肠道、促进维生素和矿物质的吸收等作用。亚麻籽作为一种特色油料作物,主要应用于亚麻籽油的加工,榨油的副产物亚麻籽饼则主要用于饲料生产,饼的利用价值较低。然而亚麻籽饼中总膳食纤维含量高达45.4%(干重)左右,其中水溶性膳食纤维占比1/3,且相较于其他原料来源的水溶性膳食纤维,亚麻籽水溶性膳食纤维具有低黏度特异性优势,在现代食品工业中应用潜力巨大。因此,探究亚麻籽饼中膳食纤维的赋存形态、建立高效的膳食纤维提取方法并明确其结构特征和功能特性,对丰富市场化膳食纤维资源、提高亚麻籽饼利用率、实现其高值化应用具有重要意义。该文简述了膳食纤维的特性、提取方法及其在食品研究中的的应用,为膳食纤维的开发和利用提供理论支持和思路借鉴。Dietary fiber(DF)is known as the“seventh largest nutrient”and has the function of regulating the intestines and promoting the absorption of vitamins and minerals.Flaxseed,as a characteristic oilseed crop,is mainly used for the processing of flaxseed oil,while the by-product of oil extraction,flaxseed cake,is mainly used for feed production,with a low cake utilization value.However,the total dietary fiber content in flaxseed cake is as high as 45.4%(dry weight),with water-soluble dietary fiber(SDF)accounting for one-third.Compared to SDF from other raw materials,flaxseed SDF has the advantage of low viscosity specificity and great potential for application in the modern food industry.Therefore,exploring the occurrence forms of dietary fiber in flaxseed cake,establishing efficient methods for extracting dietary fiber,and clarifying its structural and functional characteristics are of great significance for enriching market-oriented dietary fiber resources,improving the utilization rate of flaxseed cake,and achieving its high-value application.Based on this,this article briefly described the characteristics,extraction methods,and applications of dietary fiber in food research.It offers theoretical support and ideas for the development and utilization of dietary fiber.
