Embodiment 1

[0023] Each group selects 3kg of whole white fungus raw materials without mildew and puts them into the extraction pot, the ratio of material to water is 1:60, add 0.2% defoamer and enzymolysis accelerator polyoxypropylene polyoxyethylene glyceryl ether, and steam first The jacket is heated up, and after the temperature rises to 95°C, steam is passed into the tank for boiling extraction. The temperature of the material liquid for boiling extraction is maintained at 110°C-121°C. The tank pressure and pressure-holding boiling extraction time of each group are shown in the following table 1 :

[0024]After the feed liquid after boiling extraction is discharged, the colloid mill is used for wet pulverization, and the particle size of suspended solids after pulverization is 80 μm. The feed liquid after wet pulverization is extracted with a high-efficiency enzyme activity accelerator combined with a compound enzyme, and 2% sodium acetate and 0.2% magnesium sulfate are added to the f...

Embodiment 2

[0029] In order to more intuitively demonstrate the technological advantages of the compound enzymolysis of the present invention, the new process technology of the present invention, which can be customized to prepare high-purity Tremella polysaccharides with a full range of molecular weights, different enzymes, different enzymatic hydrolysis, and different enzymatic hydrolysis accelerators Carry out the comparative example of Tremella polysaccharide preparation, grouping and experimental results are shown in the following table 2, including the following steps:

[0030] Each group selects 3 kg of whole white fungus raw materials without mildew and puts them into the extraction pot, the ratio of material to water is 1:70, with or without adding 0.2% defoamer and enzymolysis accelerator polyoxypropylene polyoxyethylene glyceryl ether, First pass the steam jacket to heat up the temperature. After the temperature rises to 95°C, pass steam into the tank for boiling extraction. The...

Embodiment 3

[0035] In order to more intuitively demonstrate the technological advantages of steam pressure-preserved boiling extraction of the present invention, each group selects 3 kg of whole white fungus raw materials without mildew and puts them into the extraction pot. The ratio of material to water is 1:40, according to the grouping in Table 3 below, Add or not add 0.2% defoamer, first pass the steam jacket to heat up the temperature, after the temperature rises to 95°C, pass steam into the tank for boiling extraction, the temperature of the liquid extracted by boiling is maintained at 110°C-121°C, each The tank pressure of the group is 0.06MPa, and the pressure-holding boiling extraction time is 1h; after the boiling extraction is discharged, the colloid mill is used for wet pulverization, and the particle size of the suspended solids after pulverization is 50 μm. Add 2% sodium acetate and 0.02% magnesium sulfate to the feed liquid after wet pulverization as enzymolysis accelerator...

Abstract

The invention discloses a preparation process of tremella polysaccharides with a full range of molecular weight, including extraction, impurity removal and decolorization, coarse filtration, fine filtration, concentration, precipitation, suction filtration and drying processes, characterized in that the extraction process includes steam pressure holding The two-step extraction steps of boiling extraction and high-efficiency enzyme activity accelerator combined with compound enzyme extraction have the beneficial effect of the present invention: the polyoxypropylene polyoxyethylene glyceryl ether added in the steam pressure-preserved boiling extraction effectively solves the problem of foaming and at the same time , which can significantly promote the enzymatic hydrolysis efficiency of subsequent acid protease, cellulase and pectinase. A high-efficiency enzyme activity accelerator was unexpectedly found in the compound enzyme extraction. The auxiliary agent in the coarse filtration process can not only improve the state of the precipitated material , so that the precipitated material is uniformly dispersed fine particles, and it also improves the distillation speed in the next membrane distillation process.

Description

Technical field: [0001] The invention belongs to the technical field of cosmetic material production equipment, and more specifically relates to a preparation process of tremella polysaccharides with a full range of molecular weights. Background technique: [0002] Tremella fuciforms (Tremellla fuciforms), also known as white fungus, white fungus, chrysanthemum ear, is a high economic value, nutrient-rich colloidal edible fungi and medicinal fungi. Traditional Chinese medicine believes that it has the functions of nourishing the lungs and promoting body fluid, nourishing yin and nourishing the stomach, nourishing qi and blood, nourishing the brain and strengthening the heart. Tremella polysaccharide is the main active ingredient in Tremella, and its main chain is mannan composed of α-(1-3)-glucosidic bonds, and the 2,4,6 positions of the main chain are connected with glucose, xylose, rock The side chain composed of residues such as algalose and common uronic acid, and its a...
