Embodiment 1

[0018] A method for extracting and purifying Agaricus blazei polysaccharides, comprising the following steps: extract 300 g of dried Agaricus blazei with 1800 ml of ether Soxhlet for 2 hours to remove oil, and evaporate the residue to dryness. The residue after evaporating to dryness was extracted three times with 750ml boiling water, combined the boiling water extracts obtained three times, concentrated, centrifuged, and the supernatant was taken, and the supernatant was added with absolute ethanol 3 times the volume of the clear liquid for alcohol precipitation, and stood overnight (12h), again. The precipitate was washed three times with ethanol and acetone in turn, then dissolved in distilled water, then papain with a weight of 1‰ of the precipitate was added and placed in a water bath at 50°C for 2 hours, and the protein was removed by the Sevage method. Add 8g of activated carbon and place it in a 70°C water bath to heat for 3 hours, remove the activated carbon by filtra...

Embodiment 2

[0021] A method for extracting and purifying Agaricus blazei polysaccharides, comprising the following steps: extract 300 g of dried Agaricus blazei with 2000 ml of ether Soxhlet for 4 hours to remove oil, and evaporate the residue to dryness. The residue after evaporating to dryness was extracted with 750ml of boiling water for 3 times, and the boiling water extracts obtained three times were combined, concentrated, centrifuged, and the supernatant was taken, and anhydrous ethanol with 3 times the volume of the clear liquid was added for alcohol precipitation, and stood for 12 hours , and centrifuge again to collect the precipitate. The precipitate was washed three times with ethanol and acetone in turn, then dissolved in distilled water, then papain with a weight of 2‰ of the precipitate was added, placed in a water bath at 50°C for 4 hours, and the protein was removed by the Sevage method. Add 8g of activated carbon and place it in a 70°C water bath to heat for 4 hours, rem...

Abstract

The invention relates to an agaricus blazei polysaccharide and an extraction-purification method thereof. The method comprises the following steps: performing Soxhlet extraction on crushed dry agaricus blazei by ethyl ether, evaporatively drying residues, performing extraction by boiling water to obtain a boiling water extract, concentrating and centrifuging the boiling water extract, performing ethanol-precipitation standing on a supernatant, centrifuging again to collect precipitates, washing the precipitates, dissolving the precipitates in distilled water, adding 1 per mill-2 per mill of papain to obtain a solution, placing the solution in a water bath of 50+ / -5 DEG C for 2-4 hours, removing protein by a Sewage process, decoloring with active carbon, performing vacuum concentration, cooling, performing running water dialysis, performing ethanol-precipitation standing again, and drying the precipitates at the temperature of 60-70 DEG C, thereby obtaining coarse polysaccharide. Experiments prove that the agaricus blazei polysaccharide not only plays a very good role in physically and sensually preserving humidity of cigarettes, but also can reduce the irritation and the offensive odor of the cigarettes, enhance the mellow feel and the comfort of the cigarettes and can serve as an excellent-performance tobacco humectant applied to cigarettes.

Description

Technical field [0001] The present invention is a preparatory agent technology field, which involves a kind of ju Matsato polysaccharide, extraction method of extract, and its application as a tobacco foorist. Background technique [0002] At present, my country's cigarette industry mainly uses polycarbly hydroxyl substances such as glycerin, proply glycol, and coserol as a predator. The main purpose of using such predators is to maintain the water content of the tobacco in the process of processing and improve the processed resistance of the tobacco wire, but The above -mentioned predictor's maintenance of the water content of finished cigarettes and the improvement of the comfort of absorbing comfort is not satisfactory. [0003] Polysaccharides are made of a large amount of sugar, and a large amount of hydroxyl groups form hydrogen bonds with water molecules, which can make it have a strong water holding ability.At present, there are no relevant reports of the application of j...
