Problems solved by technology

In recent years, there have been many studies on the extraction and preparation of Poria cocos polysaccharides. The preparation methods mainly include acid degradation, alkali degradation, Smith degradation, ultrasonic degradation, enzymatic hydrolysis, carboxymethylation and sulfate esterification, etc. The extraction rate and quality of the finished product are uneven. , and most of the operation steps are too cumbersome, and need to introduce organic solvents such as ethyl acetate, acetone, acetic acid, absolute ethanol, etc., and undergo inorganic salts such as NaCl, NaOH, acetic acid, acid-base treatment, high cost, impact on the environment, organic Solvent residues cause low product quality and are not suitable for industrial production

Abstract

The invention relates to a pachymaran extraction method, a pachymaran extract and a poria cocos product combined production process. The pachymaran extraction method comprises the following steps: providing a poria cocos crude product; performing superfine grinding on the poria cocos crude product to obtain poria cocos wall-broken powder; mixing the poria cocos wall-broken powder with water, and grinding to prepare a poria cocos emulsion; carrying out enzymolysis on the poria cocos emulsion by adopting glucanohydrolase to prepare enzymatic hydrolysate; and inactivating the enzymatic hydrolysate, carrying out solid-liquid separation, and collecting the filtrate to obtain the pachymaran extract. According to the pachymaran extraction method, on the basis of ensuring the extraction rate, theuse of an organic solvent can be effectively avoided, and the product safety is improved.

Description

technical field [0001] The invention relates to the technical field of natural product extraction, in particular to a method for extracting polysaccharides from poria cocos, a joint production process of polysaccharide extract from poria cocos and poria cocos products. Background technique [0002] Poria cocos is the dry sclerotia of Polyporaceae fungus Poriacocos (Schw.) Wolf, sweet in taste, light in taste, flat in nature, has the functions of diuresis and dampness, invigorating the spleen, calming the heart, etc. Spleen deficiency, lack of food, loose stools and diarrhea, restlessness, palpitations and insomnia embolism. Poria cocos is one of the "four monarchs and eight treasures" in traditional Chinese medicine in my country. It was first recorded in the classical medical work "Shen Nong's Materia Medica", and it was listed as the top grade. It is a large variety of traditional Chinese medicine commonly used in my country for both medicine and food. It is an important t...
