Problems solved by technology

[0002] The active ingredient of white fungus extract is white fungus polysaccharide, which has moisturizing and anti-oxidant activities. Hot water immersion method is generally used, but the extraction rate of this method is very low, the extraction rate is only 1-3%, the white fungus spore wall is thick and solid, and the white fungus extraction must be broken.

Abstract

The invention discloses a preparation method of a Tremelle fuciformis extract. The method comprises the following steps of: a. soaking Tremelle fuciformis with hot water, adjusting pH to 2.5-3.5, and carrying out a constant-temperature reaction at 85-95 DEG C, wherein the weight ratio of Tremelle fuciformis to water is 1:(5-20); b. treating with an enzyme after the constant-temperature reaction, and controlling pH to 3-6 and the temperature to 40-55 DEG C, wherein the enzyme is one of cellulase, pectinase, and dextranase; c. filtering after the enzyme treatment reaction: firstly performing pumping filtration by using a gauze with 300-400 meshes at 40-50 DEG C to obtain a filtrate; d. concentrating the filtrate, and preforming heat preservation and sterilization at 85-95 DEG C for 0.5-1 hour. According to the method provided by the invention, Tremelle fuciformis is soaked by using hot water and then treated by using the enzyme to remove spore wall of Tremelle fuciformis, which is convenient for the deep extraction, and then treated Tremelle fuciformis is filtrated to obtain the final Tremelle fuciformis extract with an extraction rate as high as 85%.

Description

technical field [0001] The invention relates to a preparation method of white fungus extract. Background technique [0002] The active ingredient of white fungus extract is white fungus polysaccharide, which has moisturizing and anti-oxidant activities. Generally adopt the hot water immersion method, but the extraction rate of this method is very low, and the extraction rate is only 1-3%. Therefore, it is necessary to provide a new technical solution to solve the above problems. Contents of the invention [0003] The purpose of the present invention is to provide a preparation method of white fungus extract, which has high extraction rate and simple reaction steps. [0004] The technical scheme adopted in the present invention: [0005] The preparation method of white fungus extract, comprises the following steps: [0006] a. After soaking white fungus in hot water, adjust the pH value to 2.5-3.5, and react at a constant temperature at 85-95°C. The weight ratio of ...
