Embodiment 1

[0017] A method for extracting and purifying fig polysaccharides, comprising the steps of: extracting 300 g of crushed dried figs 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), 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 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 activ...

Embodiment 2

[0020] A method for extracting and purifying fig polysaccharides, comprising the following steps: 300 g of crushed dried figs are 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 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, remove t...

Abstract

The invention relates to a ficus carica polysaccharide, and an extraction and purification method thereof. The method concretely comprises the following steps: carrying out soxhlet extraction on the crushed dry ficus carica by using diethyl ether, drying residues and extracting by using boiling water; concentrating and centrifuging a boiling water extracting liquid; taking supernate, carry outing alcohol precipitation and standing, centrifugally collecting sediments again, and dissolving by using distilled water after washing; adding 0.1-0.2% of papain, and placing in a water bath at 50+ / -5 DEG C for 2-4 hours; removing proteins by adopting a Sevage method, carrying out vacuum concentration after decoloring by activated carbon, carrying out flow dialysis after cooling, and carrying out alcohol precipitation and standing again after dialysis is ended; and drying the sediments at 60-70 DEG C to obtain crude polysaccharide. The experiment proves that the ficus carica polysaccharide disclosed by the invention has good physical and sensory embellishing effects on cigarettes, the thrill and offensive odors of the cigarettes can be reduced, the roundness and the comfort of cigarette smoke are improved, and the ficus carica polysaccharide can be applied to the cigarettes 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 fig 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 reports on the applica...
