Problems solved by technology

Although these tobacco leaf polysaccharides extracted from natural plants have good moisturizing properties for shredded tobacco, they will bring compounds other than tobacco when used as a humectant for shredded tobacco, which is poorly coordinated with the aroma of cigarettes and affects the natural flavor of cigarettes
[0005] In addition, polysaccharides extracted from natural plants generally have antioxidant activity, but the antioxidant activity of natural polysaccharides that have not been derivatized is usually low. Therefore, how to improve the antioxidant activity of natural polysaccharides is also a hot research issue.

preparation example Construction

[0027] The embodiment of the present invention provides a kind of preparation method of succinylated tobacco polysaccharide, comprising the following steps:

[0028] (1) Extraction of polysaccharides from tobacco leaves;

[0029] (2) Refining of polysaccharides from tobacco leaves;

[0030] (3) Succinylation of polysaccharides from tobacco leaves.

[0031] The extraction of tobacco polysaccharides in step (1) is carried out as follows: grind the tobacco leaves and pass through a 40-mesh sieve, add petroleum ether to soak for 3-5 hours, and then filter to obtain the filter residue; add 300mL 80% ethanol to the filter residue for reflux extraction 2 time, 2h / time, suction filtration, the filter residue is dried and pulverized at 60°C for later use; add distilled water at about 60°C to the dried filter residue, the mass ratio of filter residue to distilled water is 1:35, and then put it into an ultrasonic cleaner, Sonicate at 380-400 W for 8-10 min, then filter, take the filtra...

Embodiment 1

[0049] Embodiment 1 of the present invention provides a kind of preparation method of succinylated tobacco polysaccharide, comprising the following steps:

[0050] (1) Extraction of polysaccharides from tobacco leaves: Grind the tobacco leaves and pass through a 40-mesh sieve, soak in petroleum ether for 3 hours, and then extract the filter residue by suction; add 300mL 80% ethanol to the filter residue for reflux extraction twice, 2h each time, and suction filter , the filter residue was dried and pulverized at 60°C for later use; distilled water at 60°C was added to the dried filter residue, the mass ratio of the filter residue to distilled water was 1:35, and then placed in an ultrasonic cleaner and ultrasonically treated at 380 W for 8 min. After filtering, the filtrate was taken for concentration and ethanol precipitation with absolute ethanol to obtain the tobacco leaf crude polysaccharide precipitate, and the calculated yield of tobacco leaf crude polysaccharide was 3.18...

Embodiment 2

[0054] Embodiment 2 of the present invention provides a kind of preparation method of succinylated tobacco polysaccharide, comprising the following steps:

[0055] (1) Extraction of polysaccharides from tobacco leaves: Grind the tobacco leaves and pass through a 40-mesh sieve, soak them in petroleum ether for 4 hours, and then extract the filter residue by suction; add 300mL of 80% ethanol to the filter residue for reflux extraction twice, 2h each time, and suction filter , the filter residue was dried and pulverized at 60°C for later use; distilled water at 60°C was added to the dried filter residue, the mass ratio of the filter residue to distilled water was 1:35, and then placed in an ultrasonic cleaner, ultrasonically treated at 400W for 8 min, and then Filtrate, take the filtrate for concentration, and use absolute ethanol to ethanol precipitate to obtain the tobacco leaf crude polysaccharide precipitate. The calculated yield of tobacco leaf crude polysaccharide is 3.57%. ...

Abstract

The invention provides a preparation method of succinylated tobacco leaf polysaccharide, which comprises the following steps: extraction of tobacco leaf polysaccharide, refining of tobacco leaf polysaccharide, and succinylation of tobacco leaf polysaccharide; the succinylation of tobacco leaf polysaccharide is carried out according to the following process : add anhydrous sodium carbonate, succinic anhydride to the aqueous solution of the tobacco leaf polysaccharide after described refining, adjust pH 9.8~10.2 after the acylation reaction is completed, carry out solid-liquid phase separation afterwards; Get the supernatant after separating and adjust pH to Neutral, dialyzed, freeze-dried. The preparation method of a succinylated tobacco leaf polysaccharide of the present invention is simple, and the degree of succinylation substitution is high; the succinylated tobacco leaf polysaccharide of the present invention is applied to the moisture retention of shredded tobacco, and has relatively slow dehydration under low humidity conditions. The water loss rate has a slower water absorption rate in a high-humidity environment, and has better moisture retention and moisture-proof functions; and the succinylated tobacco leaf polysaccharide of the present invention has better in vitro Antioxidant activity.

Description

technical field [0001] The present invention relates to the technical field of tobacco, [0002] In particular, the invention relates to shredded tobacco containing polysaccharides from tobacco leaves and polysaccharides derived therefrom with high moisture retention. Background technique [0003] A humectant is a protective substance that absorbs and releases moisture from the surrounding environment and is generally used in food, daily necessities, and tobacco. Humectants play a vital role in the storage, transportation, and processing of tobacco. Now propylene glycol and glycerin are commonly used in industry. Because propylene glycol and glycerin will produce tar and other harmful substances during the burning of cigarettes, now A part of the extract of some natural products is applied to the tobacco and plays a good moisturizing performance. [0004] Chinese patent CN201310449240.5 discloses the application scope of a pomelo polysaccharide in moisturizing tobacco leav...
