Embodiment 1

[0021] A method for extracting and purifying Morinda officinalis polysaccharides, comprising the following steps: extract 300 g of dried Morinda officinalis 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 b...

Embodiment 2

[0024] A method for extracting and purifying Morinda officinalis polysaccharides, comprising the following steps: extract 300 g of dried Morinda officinalis 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 ho...

Abstract

The invention relates to a Morinda officinalis polysaccharide and its extraction and purification method, specifically: extracting the crushed and dried Morinda officinalis with ether Soxhlet, volatilizing the residue to dryness and then extracting it with boiling water, concentrating and centrifuging the boiling water extract, and taking The supernatant was left to stand for alcohol precipitation, centrifuged again to collect the precipitate, washed and dissolved in distilled water, then added 1-2‰ papain, placed in a water bath at 50±5°C for 2-4 hours, and the protein was removed by Sevage method, after activated carbon decolorization Concentrate under reduced pressure, and then conduct running water dialysis after cooling. After the dialysis, set aside again for alcohol precipitation, and dry the precipitate at 60-70°C to obtain crude polysaccharide. Tests have proved that the Morinda officinalis 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 product 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 Morinda officinalis polysaccharide, an extraction and purification method and its application as a tobacco humectant. 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 are no relevant report...
