Abstract

The invention relates to a brassica campestris polysaccharide extract and a preparation method thereof, wherein the preparation method comprises the following steps: choosing dry brassica campestris thin sheets, crushing to obtain brassica campestris powder, adding water to the brassica campestris powder, stirring evenly, to obtain a mixed liquid A, carrying out reflux extraction, filtering to obtain filtrate and a filtrate residue after each time of reflux extraction, merging the filtrates, and concentrating to obtain a concentrated liquid A; adding the filter residues to cellulase, to obtaina mixed liquid B, adjusting the pH of the mixed liquid B, carrying out enzymatic hydrolysis, carrying out enzyme deactivation, and filtering, to obtain a hydrolytic filtrate; and mixing the filtrateand the hydrolytic filtrate to obtain mixed filtrate, then adding an ethanol aqueous solution, mixing evenly, carrying out alcohol precipitation, carrying out centrifugal separation by a centrifugal machine, to obtain a precipitate, and drying. The brassica campestris polysaccharide prepared under the conditions does not destroy a molecular structure of the brassica campestris polysaccharide. By addition of cellulase, hydrolysis reaction is carried out, and the percentage content of the polysaccharide in the brassica campestris polysaccharide extract cannot be reduced in the premise of shortening of the reflux extraction time.

Description

technical field [0001] The invention belongs to the technical field of food, and in particular relates to an extract of Qiamagu polysaccharide and a preparation method thereof. Background technique [0002] Chamagu is an alkali-rich plant that has been eaten by Uyghurs in Xinjiang for more than 2,000 years. The medicinal name of Qiamagu is turnip, which is a biennial cruciferous herb, rich in calcium, iron, zinc, potassium and other healthy alkaline mineral elements and organic alkaloids, and also rich in protein, crude Fiber, linoleic acid, flavonoids, polysaccharides, saponins and nineteen kinds of amino acids and other substances. It mainly grows in the southern Tianshan Mountains, the northwest of the Tarim Basin, and the Changshou area of ​​the Red Desert. [0003] Long-term consumption of Qiamagu can prevent and alleviate arteriosclerosis, prevent and treat cardiovascular and cerebrovascular diseases, relieve cough, eliminate phlegm, freshen the lungs, prevent varico...
