Abstract

The invention relates to a technique combination for extracting polysaccharide in glossy ganoderma mycelium cell. According to the mass ratio, the solid-liquid ratio is 1:10-1:60, the adding quantity of complex enzyme is 0.5-5.0% of the mass of raw materials, the range of ultrasonic wave power is within 100-500W, the range of enzymolysis time is 40-100min, the range of enzymolysis temperature is 30-60 DEG C, and the pH value range of enzymolysis is 4.0-8.0. The technique for extracting polysaccharide in glossy ganoderma mycelium cell and the method thereof comprise: high quality mycelium is selected for submerged fermentation to obtain mycelium dry powder; the solid-liquid ratio is determined; the adding quantity of the complex enzyme is determined; and the optimum extraction technique combination for extracting the mycelium dry powder polysaccharide by using an ultrasonic wave-composite enzymolysis method is determined.

Description

technical field [0001] The invention relates to biopharmaceutical production technology, in particular to a process for extracting intracellular polysaccharides from Ganoderma lucidum mycelia and a method for determining the same Background technique [0002] Ganoderma lucidum is a traditional Chinese medicine in my country. In traditional Chinese medicine, it has the functions of nourishing and strengthening, strengthening the body and strengthening the body. It has been used for more than 2,000 years. Scientific research believes that Ganoderma lucidum has multiple functions such as two-way immune regulation, lowering blood fat, anti-aging and anti-tumor. These functions come from a variety of biologically active substances in Ganoderma lucidum, and Ganoderma lucidum polysaccharide is the main component. [0003] Ganoderma lucidum polysaccharides are widely used in medicine, food and other fields, and the market demand is increasing day by day. However, at present, the pro...
