Abstract

The invention discloses a method for preparing edible burdock soluble dietary fiber powder by taking burdock roots as raw materials, and belongs to the field of the extraction and separation of natural components of plants. Edible burdock soluble dietary fiber powder can be prepared through steps and technologies of pretreating, extracting, separating, concentrating and drying fresh burdock roots.The yield of the prepared edible burdock soluble dietary fiber powder can reach 25.3%, and the total sugar content can reach 97.2%, so that the edible burdock soluble dietary fiber powder can be usedas the efficacy components of health products and functional food; and the method simplifies the steps of the raw material pretreatment, extraction and separating of edible burdock soluble dietary fibers, the using of ethanol and other organic solvents can be avoided, so that production costs can be significantly reduced, and therefore, the method is an energy-saving and efficient preparation method of the edible burdock soluble dietary fiber powder.

Description

technical field [0001] The invention relates to a method for extracting and separating natural components in burdock root, belonging to the technical field of extraction and separation of natural components of plants, in particular to a method for preparing burdock soluble dietary fiber micropowder by using burdock root as a raw material. Background technique [0002] Soluble dietary fiber, also known as soluble viscous fiber, is a special nutrient whose essence is a type of polysaccharide in carbohydrates that cannot be digested and absorbed by the human body. Soluble dietary fiber can be dissolved in water and swelled by water absorption, and can be digested by microorganisms in the human intestinal tract. Such polysaccharides often exist in plant cytosol and intercellular substance, mainly including polysaccharides such as viscose, vegetable gum and pectin. Soluble dietary fiber can stimulate human intestinal peristalsis, which is conducive to the excretion of feces, and...
