Abstract

The invention discloses a preparation method of pleurotus eryngii dietary fiber, and belongs to the technical field of deep processing of agricultural products. The preparation method of the pleurotus eryngii dietary fiber comprises the following steps: soaking pleurotus eryngii residues separated out after polysaccharide extraction into edible alcohol, filtering to remove proteins, washing the pleurotus eryngii residues with water, adding inorganic alkali, heating for hydrolysis, washing the pleurotus eryngii residues to be neutral after alkaline hydrolysis, adding inorganic acid, heating for hydrolysis, washing the pleurotus eryngii residues with water and filtering after acid hydrolysis, drying, crushing, adding a well-cultured probiotic culture solution, and performing low-temperature spray drying to obtain the probiotic-rich pleurotus eryngii dietary fiber. In the preparation method, the pleurotus eryngii residues separated out after polysaccharide extraction are made full use for preparing the probiotic-rich pleurotus eryngii dietary fiber; the preparation method is simple and reasonable in process route; an acid method and an alkali method are combined, so that the environment is not polluted; the preparation method is convenient in operation and low in production cost.

Description

technical field [0001] The invention belongs to the technical field of intensive processing of agricultural products, and relates to a preparation method of Pleurotus eryngii dietary fiber health food rich in probiotics. Background technique [0002] Dietary fiber (dietary fiber, DF) usually refers to the sum of edible plant ingredients, carbohydrates and similar substances that can resist digestion and absorption in the small intestine of the human body and can be partially or completely fermented in the large intestine of the human body, including some indigestible Polysaccharides, oligosaccharides, lignin and other plant associations. According to the solubility characteristics of DF, it can be divided into water-soluble dietary fiber (soluble dietary fiber, SDF) and water-insoluble dietary fiber (insoluble dietary fiber, IDF). DF mainly includes cellulose, hemicellulose, lignin and so on. Although DF cannot be digested and absorbed by the human body, a large number of s...
