Embodiment 1

[0018] A method for extracting and purifying jujube polysaccharide, comprising the following steps: extracting 300 g of pulverized dry jujube with 1800 ml of diethyl ether Soxhlet for 2 hours to remove grease, and volatilizing the residue to dryness. The residue after volatilization was extracted 3 times with 750ml of boiling water, the boiling water extracts obtained for 3 times were combined, concentrated, centrifuged, the supernatant was taken, added with 3 times the volume of absolute ethanol for alcohol precipitation, and allowed to stand overnight (12h), again. 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 1‰ of the precipitate was added and placed in a 50°C water bath for 2h, and the protein was removed by the Sevage method. Add 8g of activated carbon and place it in a 70°C water bath and heat for 3h, filter to remove the activated carbon, concentrate under reduced pr...

Embodiment 2

[0021] A method for extracting and purifying jujube polysaccharide, comprising the following steps: extracting 300 g of pulverized dry jujube with 2000 ml of diethyl ether Soxhlet for 4 hours to remove grease, and volatilizing the residue to dryness. The residue after volatilization was extracted three times with 750ml of boiling water, and the boiling water extracts obtained from the three times were combined, concentrated, centrifuged, the supernatant was taken, and the supernatant was added with 3 times the volume of absolute ethanol for alcohol precipitation, and allowed to stand for 12h. , and centrifuge again to collect the precipitate. The precipitate was washed three times with 300ml ethanol and 300ml acetone in turn, dissolved in distilled water, and then added papain with a weight of 2‰ of the precipitate and placed in a 50°C water bath for 4h, and the protein was removed by the Sevage method. Add 8g of activated carbon and place it in a 70°C water bath for 4 hours, ...

Abstract

The invention relates to Chinese date polysaccharide and a method for extracting and purifying the Chinese date polysaccharide. The method for extracting and purifying the Chinese date polysaccharide comprises the following concrete steps: carrying out Soxhlet extraction on smashed dried Chinese date, volatilizing and drying residue and then extracting with boiled water, carrying out concentration and centrifugation on a boiling water extracting solution, taking supernate and carrying out alcohol precipitation, standing, centrifuging again, collecting precipitate, dissolving with distilled water after washing, then adding 0.1-0.2% of papain, placing in water bath at the temperature of 50 minus or plus 5 DEG C for 2-4 hours, removing protein by adopting a Sevage method, decolorizing with activated carbon and then carrying out reduced pressure concentration, cooling, carrying out dialysis with running water, carrying out alcohol precipitation and standing again after dialysis is finished, and drying precipitate at the temperature of 60-70 DEG C, so that the Chinese date polysaccharide is obtained. Tests prove that the Chinese date polysaccharide has good physical and sensory organ moisture retaining effects on cigarette, can be used for reducing the irritation and offensive odour of the cigarette and improving the mellow and full sense and comfort of smoke of the cigarette and can serve as a tobacco humectant with excellent performance.

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...
