[0005] Chinese patent document CN1765935A (application number: 200510017261.5) discloses a new method for separating lentinan and lentinan, and Chinese patent document CN101736055A (application number: 200810162120.6) discloses a method for extracting black fungus polysaccharides. The preparation of the above polysaccharides The processes are all proposed for a single polysaccharide product, and the extraction of edible fungus polysaccharides alone is time-consuming and labor-intensive, and the activity of edible polysaccharides is not strong
But this method adopts microwave method combined with condensation reflux extraction, and this patent has the following disadvantages: 1) the steps are loaded down with trivial details, and extraction time is relatively long, time-consuming and labor-intensive, 2) microwave combined with condensation reflux extraction time is long, and microwave radiation reaches a certain level, It will destroy the components of the target extract, and the activity of the prepared edible fungus complex polysaccharide will be greatly reduced

Abstract

The invention discloses a preparation process for edible fungus compound polysaccharide. The preparation process comprises the following steps: respectively cleaning and drying fruiting bodies of mushroom, tremella and hericium erinaceus as raw materials until the water content is 5 to 10 percent; crushing the raw materials and sieving to obtain edible fungus powder; mixing the edible fungus powder of the mushroom, the tremella and the hericium erinaceus according to the weight ratio of 1:1:1; and carrying out degreasing, ultrasonic water extraction, filtering, secondary ultrasonic water extraction, condensing, washing and drying on the mixed edible fungus powder to obtain the edible fungus compound polysaccharide. The edible fungus compound polysaccharide prepared by adopting the preparation process disclosed by the invention has the advantages of strong activity, over 10 percent addition of removal rate of free group (O<2->.) compared with single extraction of polysaccharide, high efficacy, simpleness in preparation process and strong operability.

Description

technical field [0001] The invention relates to a preparation process of edible fungus compound polysaccharides, in particular to a preparation process of mushrooms, white fungus and Hericium erinaceus compound polysaccharides. Background technique [0002] Edible fungi, also known as edible (medicinal) fungi, are a type of large edible (medicinal) fungi with high edible and medicinal value. The common types of edible fungi used for health care and disease prevention in my country mainly include: Hericium erinaceus There are more than 20 kinds of mushrooms, shiitake mushrooms, maitake frondosa, tremella, Coprinus comatus, black fungus, northern Chinese caterpillar fungus and Ganoderma lucidum, etc. These edible fungi are rich in biologically active substances, such as polysaccharides, polypeptides, nucleosides and triterpenes It has been proved by scientific experiments that these biologically active substances have various functions such as anti-oxidation, anti-tumor, lowerin...
