Embodiment 1

[0013] A method for extracting ganoderma polysaccharides, comprising the following steps:

[0014] (1) Raw material processing: removing impurities and cleaning the ganoderma lucidum, then soaking it in citric acid water for 24 hours, draining it for later use after soaking; wherein the concentration of the citric acid water is 1.2% (mass percentage), the ratio of ganoderma lucidum to citric acid water 4-5g: 10ml; put the Ganoderma lucidum pulp into the container, add 2-3 times the weight of distilled water, then add 0.1-0.2% high-temperature liquefied enzyme and mix well, boil for 30 minutes, cool to room temperature; then put it in 38-42℃ In a constant temperature water bath, adjust the pH to 5.5, add 0.6-0.8% ganoderma lucidum compound enzyme by weight, stir and keep warm for 100-120min to obtain saccharified syrup; the high-temperature liquefying enzyme activity is 100,000 U / ml.

Abstract

The invention relates to an extraction method of ganoderma lucidum polysaccharide. The extraction method comprises the steps of cleaning and crushing ganoderma lucidum or ganoderma lucidum stems, performing extraction with complex enzymes, performing refining, performing concentration, and performing spray drying so as to obtain the ganoderma lucidum polysaccharide. The extraction method disclosedby the invention is simple in technology, has the notable characteristics of being high in polysaccharide extraction rate, high in polysaccharide content and low in extraction temperature, and besides, an extraction process is free from pollution of organic solvents, environmentally friendly, low in energy consumption and economically feasible.

Description

technical field [0001] The invention belongs to the technical field of food, and in particular relates to a method for extracting ganoderma polysaccharides. Background technique [0002] Ganoderma lucidum, also known as Lin Zhongling and Qiongzhen (scientific name: Ganoderma Lucidum Karst), is the fruiting body of the polyporaceae fungus Ganoderma lucidum. It has the effects of invigorating qi and calming the nerves, relieving cough and asthma, and prolonging life. As a traditional Chinese medicinal material with thousands of years of medicinal history, Ganoderma lucidum has high medicinal and edible value. After decades of modern pharmacological research by scientific research institutions, it has been confirmed that Ganoderma lucidum can enhance human immunity, regulate blood sugar, and control blood pressure. Liver protection and detoxification, anti-tumor, anti-aging, anti-allergic, anti-neurasthenia, sleep promotion and other effects; in addition, Ganoderma lucidum has...
