Abstract

The invention discloses a method for extracting agaricus lentinan. The method comprises the following steps: pulping agaricus bisporus; adjusting pH value of the pulp; carrying out composite hydrolysis on the pulp; passivating enzyme; carrying out microwave treatment on the pulp; preserving temperature of the pulp; filtering the pulp; centrifuging the pulp; concentrating the pulp under reduced pressure; removing protein of the pulp by an Sevage method; precipitating alcohol; centrifuging the pulp; filtering the pulp by a membrane; adsorbing the pulp by resin; desorbing the pulp; concentrating the pulp in vacuum; and drying the pulp in vacuum to obtain the agaricus lentinan. The method has the characteristics of high extraction rate and high extracting purity of the agaricus lentinan, and has no emission of pollutant in a technical process, low energy consumption and reasonable design of the process method.

Description

technical field [0001] The invention relates to a method for extracting Agaricus bisporus polysaccharide, which belongs to the separation technology of microbial chemical macromolecular compounds. Background technique [0002] Agaricus burnnescens peck, scientific name mushroom, white mushroom or mushroom, belongs to Fungiphylum, Basidiomycotina, Laminomycetes, Agaricaceae, and Mushroomaceae; it is a wild edible fungus with both food and medicine. It has the characteristics of high protein, low fat, and a complete range of amino acids. It also has the effects of benefiting the spleen, clearing the heart and calming the nerves, helping food, and curing hemorrhoids. It also has the effect of regulating human metabolism and enhancing human physique; It is an important component and energy substance, and also has various physiological functions such as immunity and anti-cancer. [0003] Chinese Patent Application No. 200810222270.1 discloses "a Agaricus bisporus extract and its...
