Embodiment 1

[0030] a. Wash the whole plant of Fenbei Schisandra and put it in an oven at 45°C to dry and pulverize it to 40 meshes to obtain Fenbei Schisandra powder;

[0031] b. Add Schisandra Fenbei powder to water 20 times the weight of Fenbei Schisandra powder, and reflux extraction at 100°C for 3 hours to obtain an extract;

[0032] c. After the extract is cooled, the filtrate is obtained after 10000r / min high-speed centrifugation and vacuum filtration, and the filtrate is concentrated in vacuum to 1 / 15 of the volume of the extract to obtain a concentrate;

[0033] d. Add ethanol with a volume fraction of 95% to the concentrated solution, so that the volume fraction of ethanol in the system reaches 85%, stir, let stand for 10 hours, centrifuge at 4000r / min for 15 minutes, collect the precipitate, and freeze-dry to obtain Schisandra chinensis polysaccharide .

[0034] According to 0.1‰ of the cut tobacco quality, weigh the Schisandra chinensis polysaccharide, make a solution of 0.4 m...

Embodiment 2

[0036] a. After washing the whole plant of Schisandra Fenbei, put it into an oven for drying at 40° C., take the dried sample and pulverize it to 60 mesh, and obtain Fenbei Schisandra powder;

[0037] b. Add Schisandra Fenbei powder to water 25 times the weight of Fenbei Schisandra powder, reflux and extract at 90°C for 4 hours to obtain an extract;

[0038] c. Cool the extract to room temperature, centrifuge at a high speed of 8000r / min for 15min, vacuum-filter the supernatant, and concentrate the filtrate in vacuum to 1 / 20 of the volume of the extract to obtain a concentrate;

[0039] d, add pure alcohol (i.e. ethanol with a volume fraction of 100%) to the concentrated solution, stir continuously, so that the volume fraction of ethanol in the system reaches 90%, leave it for 8h, centrifuge at 4000r / min for 15min, collect the precipitate, and freeze-dry it immediately Obtain Fenbei Schisandra (whole plant) crude polysaccharide.

[0040] Weigh the obtained Schisandra chinensi...

Embodiment 3

[0042] a. Wash the whole plant of Fenbei Schisandra and put it into an oven at 30°C to dry and pulverize it to 100 mesh, so as to obtain Fenbei Schisandra powder;

[0043] b. Add Schisandra Fenbei powder to water 50 times the weight of Fenbei Schisandra powder, and reflux extraction at 70°C for 2 hours to obtain an extract;

[0044] c. After the extract is cooled, the filtrate is obtained after 10000r / min high-speed centrifugation and vacuum filtration, and the filtrate is concentrated in vacuum to 1 / 10 of the volume of the extract to obtain a concentrate;

[0045] d. Add ethanol with a volume fraction of 98% to the concentrated solution, so that the volume fraction of ethanol in the system reaches 75%, stir, let stand for 12 hours, centrifuge at 4000r / min for 15 minutes, collect the precipitate, freeze-dry to obtain the powdered back Schisandra polysaccharide .

[0046] According to 0.08‰ of the cut tobacco quality, weigh the Schisandra chinensis polysaccharide, make a solut...

Abstract

The invention discloses a plant polysaccharide and a preparation method thereof as well as an application of the plant polysaccharide in cigarette. The preparation method comprises the following steps of: washing a plant and then drying, and extracting in water after smashing so as to obtain extract, wherein the weight ratio of the plant to the water is 1: (20-50); cooling the extract and then carrying out centrifugation and vacuum filtration, concentrating filtrate in vacuum until the volume of filtrate is 1 / 30-1 / 10 of that of the extract so as to obtain a concentrated solution; adding 95%-100% by volume of ethanol into the concentrated solution so that the volume fraction of ethanol in a system reaches 75%-90%; and stirring and standing for 8 hours-12 hours, centrifuging, collecting precipitate, carrying out freeze drying so as to obtain the plant polysaccharide. According to the invention, the plant is schisandra chinensis powder, Ludiju or fiveleaf gynostemma herb; and the method is simple to operate and low in cost, is easy to control and suitable for industrial production. The prepared plant polysaccharide is applied to the cigarette, the form of smoke is good when the cigarette is burnt and sucked, drying sense is reduced, mellow and full sense and aroma are increased, and brightness is obviously promoted.

Description

technical field [0001] The invention relates to the field of preparation and application of polysaccharides, in particular to a plant polysaccharide, its preparation method and its application in cigarettes. Background technique [0002] Cigarette flavoring and moisturizing technology has always been the key to highlighting the characteristic aroma and personalized style of tobacco products. Moisturizing performance is an important factor affecting the aroma, flavor and smoking comfort of cigarettes. It is an important basis and basis for building the core technology of Chinese cigarettes. Assure. At present, the moisturizing performance of cigarettes is mainly improved by adding propylene glycol, glycerin and other substances as humectants in China, but the moisturizing effect is not obvious enough, and there are still problems such as rapid water dispersion, low smoke moisture, and high irritation. my country, such as Zhejiang Province, is rich in characteristic plant res...
