Embodiment 1

[0020] 1. Pretreatment of Agaricus Blazei

[0021] Rinse the fresh Agaricus blazei gently with running water at 15°C-20°C, remove inedible impurities, drain, and carry out centrifugal dehydration at 2000 rpm to keep the water content in a natural state, and then dry it at 60°C- Drying with hot air at 80°C to make the water content less than 8%, and crushing the dried Agaricus blazei powder to obtain Agaricus blazei powder with a particle size of less than 1mm.

[0022] 2. Degreasing and deodorizing treatment

[0023] Supercritical CO 2 Fluid extraction, extraction pressure 8MPa, temperature 32°C, time 60 minutes, CO 2 The flow rate is 20L / h. The extracted agaricus blazei powder is light yellow in color, has a pure almond flavor, has no foreign smell, and has a lipid content of less than 0.2%. The extract is a golden yellow lipid substance, and the main component is linoleic acid.

Abstract

A method for preparing pine mushroom active polysaccharides, which belong to health food process technology. The process comprising removing the foreign matter in the pine mushroom, drying and disintegrating; supercritical extracting the powder with carbon dioxide, which can remove most of the lipid matter and odorant; adding proportional drinking water and extracting water-solubility active polysaccharides under certain temperature and for a certain long time; filtering to get the active polysaccharides solvent; then carrying out the process of vacuum concentration, sediment with alcohol, separation, drying and getting the product, filter residue can be used to prepare high-fiber food if treated properly. The invention is characterized by the increase of the extraction rate and biological active, no denaturation of the raw material in extraction process and no pollution in whole production process, and the full utilization of the raw material.

Description

technical field [0001] The invention belongs to health food processing technology. Background technique [0002] Active polysaccharides refer to polysaccharide compounds with certain special physiological activities, including dietary fiber and edible fungus polysaccharides. Edible fungus polysaccharide has a variety of physiological functions, such as antibacterial, anti-inflammatory, improving the body's immunity; promoting the recovery of the sick body; lowering blood sugar, preventing and treating diabetes caused by elevated blood sugar; and having a good therapeutic effect on gastrointestinal tumors. In addition, medical and nutritional studies have proved that adequate intake of polysaccharides from edible fungi can protect the body from some diseases. Edible fungus polysaccharide is a general term for polysaccharide carbohydrates with similar structures, and the chemical composition of various edible fungus polysaccharide products varies greatly. Therefore, the phys...
