Embodiment 1

[0018] A method for extracting and purifying jujube polysaccharides, comprising the steps of: extracting 300 g of crushed dried jujube with 1800 ml of ether Soxhlet for 2 hours to remove oil, and evaporating 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 300ml ethanol and 300ml acetone in turn, and 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 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 jujube polysaccharides, comprising the following steps: 300 g of crushed dried jujube is extracted with 2000 ml of ether Soxhlet for 4 hours to remove oil, and the residue is evaporated 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 3 times with 300ml ethanol and 300ml acetone in turn, and then dissolved in distilled water, then papain with a weight of 2‰ of the precipitate was added and 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 fo...

Abstract

The invention relates to a jujube polysaccharide and a method for extracting and purifying the same. Specifically, the crushed and dried jujube is extracted with ether Soxhlet, the residue is evaporated to dryness and then extracted with boiling water, the boiling water extract is concentrated and centrifuged, and the supernatant is taken Let the liquid alcohol settle down, collect the precipitate by centrifugation again, dissolve it with distilled water after washing, then add 1-2‰ papain, place it in a water bath at 50±5°C for 2-4 hours, use the Sevage method to remove the protein, decompress with activated carbon Concentrate, cool down, and dialyze with running water. After the dialyzing is over, let it stand for alcohol precipitation again, and dry the precipitate at 60-70°C to obtain crude polysaccharide. Tests have proved that the jujube polysaccharide of the present invention has a good physical and sensory moisturizing effect on cigarettes, and can reduce the irritation and miscellaneous gas of cigarettes, improve the roundness and comfort of cigarette smoke, and can be used as a kind of cigarette with excellent performance Tobacco humectants are used in cigarettes.

Description

technical field [0001] The invention belongs to the technical field of humectants, and in particular relates to a jujube polysaccharide, an extraction and purification method and its application as a humectant for tobacco. Background technique [0002] At present, glycerin, propylene glycol, sorbitol and other polyhydroxy substances are mainly used as humectants in the cigarette industry in my country. The main purpose of using such humectants is to maintain the moisture content of shredded tobacco during processing and improve the processing resistance of shredded tobacco. The above-mentioned humectant has unsatisfactory effects on maintaining the moisture content of finished cigarettes and improving smoking comfort. [0003] Polysaccharides are composed of a large number of monosaccharides, and a large number of hydroxyl groups form hydrogen bonds with water molecules, which can make them have strong water holding capacity. At present, there is no relevant report on the ap...
