Embodiment 1

[0014] This example provides a method for extracting and purifying Pueraria polysaccharides and its application in tobacco humectants. The Pueraria polysaccharides are obtained through the following steps, as follows: (1) Pueraria medicinal materials are dried in an oven at 70°C to a constant mass and then pulverized , passed through a 40-mesh sieve, put it in a dry dish and sealed it for storage, accurately weighed 30g of kudzu root powder into a round-bottomed flask; (2) Added 300mL of 80% ethanol to the round-bottomed flask and soaked it for 1h, treated it with 200W ultrasonic power for 30min, and extracted it by ultrasonic The frequency is once, centrifuged at 5000r / min for 20min, and the supernatant a is recovered; (3) The obtained residue is washed twice with 80% ethanol, absolute ethanol, acetone, ether, and then treated at a certain ultrasonic power for 30 min, and the number of times of ultrasonic extraction is 1 time to obtain the supernatant b; (4) decolorize the sup...

Embodiment 2

[0018] This example provides a method for extracting and purifying Pueraria polysaccharides and its application in tobacco humectants. Pueraria polysaccharides are obtained through the following steps. The steps are as follows: (1) Pueraria medicinal materials are dried in an oven at 80°C to a constant mass and then pulverized , pass through a 50-mesh sieve, put it in a dry dish and store it sealed, accurately weigh 40g of kudzu root medicinal powder and put it in a round bottom flask; (2) Add 800mL80% ethanol to the round bottom flask for 1-3h, and treat it with 300W ultrasonic power for 40 min , the number of ultrasonic extraction is 2 times, centrifuged at 6000r / min for 30min, and the supernatant a is recovered; (3) The obtained residue is washed 3 times with 85% ethanol, absolute ethanol, acetone, ether, and then After treatment for 40 min, the number of times of ultrasonic extraction was 2 times to obtain supernatant b; (4) dewhiten the supernatant a and supernatant b obta...

Embodiment 3

[0023] This example provides a method for extracting and purifying Pueraria polysaccharides and its application in tobacco humectants. The Pueraria polysaccharides are obtained through the following steps. , pass through a 60-mesh sieve, put it in a dry dish and seal it for storage, accurately weigh 50g of kudzu root medicinal powder and put it in a round-bottomed flask; (2) add 1000mL of 95% ethanol to the round-bottomed flask to soak for 3h, treat with ultrasonic power 500W for 60min, and ultrasonically The number of extractions is 3 times, centrifuged at 8000r / min for 40min, and the supernatant a is recovered; (3) The obtained residue is washed 5 times with 95% ethanol, absolute ethanol, acetone, ether, and then treated at a certain ultrasonic power 60 min, the number of times of ultrasonic extraction was 3 times, and the supernatant b was obtained; (4) the supernatant a and supernatant b obtained above were dewhitened by the Sevag method for several times, and then decolori...

Abstract

The purpose of the invention is to provide an extraction and purification method of Radix Puerariae polysaccharides and an application of the Radix Puerariae polysaccharides in a tobacco humectant. The polysaccharides are obtained by adopting ultrasonic extraction and other technical schemes in order to achieve the purpose. The Radix Puerariae polysaccharides are rich in hydroxyl groups and hydrogen bonds, and can form hydrogen bonds with water molecules to reduce volatilization of moisture or trap moisture in air, so that the stability of the moisture content is kept; and test results show that when the addition amount of the Radix Puerariae polysaccharides in tobacco shreds is 0.1%, the obtained tobacco shreds has a lower water loss rate than a group of tobacco shreds added with propylene glycol and a group of tobacco shreds added with glycerol, and have a good moisture retention effect. Radix Puerariae contains various trace elements, can enhance the immunity function of human bodies, and has a good health-care effect. Radix Puerariae resources in China are rich, and the Radix Puerariae polysaccharides used as the humectant has the advantages of low extraction cost, good performances and safety, and are expected to be used as a novel humectant for tobacco processing.

Description

technical field [0001] The invention belongs to the technical field of humectants, and in particular relates to a kudzu root 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 polymerized from a large number of monosaccharides. A large number of hydroxyl groups form hydrogen bonds with water molecules, which can make them have a strong water holding capacity. Plant polysaccharides are rich in hydroxyl grou...
