Embodiment 1

[0027] A method for preparing black fungus polysaccharides extracted by microwave and ultrasonic waves, characterized in that: the main process is: pretreatment of black fungus, water bath infiltration, microwave and ultrasonic extraction of black fungus polysaccharides, concentration, purification, polysaccharide precipitation, specific operation method Follow these steps in order:

[0028] 1. Pretreatment of black fungus:

[0029] Select black fungus with plump and plump flesh, no mildew, no incompleteness, and no insect erosion, dry it with a dryer until the water content is less than 5%, pulverize it with a pulverizer, pass through a 40-100 mesh sieve, and prepare black fungus powder for later use;

[0030] 2. Water bath infiltration:

[0031] Add an appropriate amount of water to the black fungus powder prepared above according to the ratio of solid to liquid of 1:10-1:30, and soak in a water bath at 50°C-70°C for 20-30 minutes;

[0032] 3. Microwave and ult...

Abstract

The invention discloses a preparation method of black fungus polysaccharide by microwave assisted ultrasonic extraction. According to the invention, black fungus polysaccharide is prepared through the process steps of raw material black fungus pretreatment, water bath infiltration, black fungus polysaccharide microwave assisted ultrasonic extraction, concentration, purification, polysaccharide precipitation and the like. According to the invention, extraction is carried out with cooperation of microwave and ultrasonic wave, such that black fungus polysaccharide can be fully released. Therefore, extraction time is shortened, and polysaccharide extraction rate is improved.

Description

Technical field: [0001] The invention relates to the technical field of extracting black fungus polysaccharides, in particular to a preparation method for extracting black fungus polysaccharides with microwave and ultrasonic waves. Background technique [0002] Black fungus belongs to the fungus Basidiomycetes Auricularia and is a favorite food for people. Its texture is tender, crisp and smooth. In addition to rich in protein, vitamins, calcium, phosphorus, copper and other substances, the fruiting body also contains a large amount of Biologically active polysaccharide is an important medicinal and edible fungus. Black fungus not only has high nutritional value, it also has high medicinal value. Medical research has proved that black fungus has the functions of nourishing qi and strengthening the body, nourishing the kidney and nourishing the stomach, and promoting blood circulation. It is an edible fungus with high medicinal value. [0003] my country is the main fungus...
