Embodiment 1

[0022] Undaria pinnatae was washed by infrared enzymes, removed impurities, dried in the air, baked in an oven at 50°C for 3 hours, crushed and passed through a 40-mesh sieve to obtain wakame powder, added 4 times the amount of water, and dried at 70°C Extract with water for 2 hours, centrifuge the extract, filter the supernatant with gauze, concentrate the filtrate to 80% of the volume of the original filtrate, then add 3 times the volume of 95% ethanol, let it stand for 24 hours, filter and dry through gauze to obtain crude undaria pinnatifida. Polysaccharide, the yield is 7.8%.

[0023] The undaria pinnatifida crude polysaccharide is dissolved in water, and the added amount is 0.005% of the weight of shredded tobacco, and is evenly sprayed on shredded tobacco in the cigarette feeding process to make cigarettes. After smoking, the smoke has no peculiar smell, the miscellaneous gas and irritation of the cigarette smoke are slightly reduced, the sweetness is increased, the aro...

Embodiment 2

[0025] Undaria pinnatifida is inactivated by infrared, washed clean, removed impurities, dried in the air, baked in an oven at 40°C for 4 hours, crushed and passed through a 20-mesh sieve, in a microwave extraction device, using 320w power, according to the ratio of 1:3 Liquid ratio (m:m), extract with water for 6min, after the extract is centrifuged, filter the supernatant with gauze, concentrate the filtrate to 80% of the original filtrate, then add 3 times the volume of 95% ethanol, let it stand for 24h, filter A flocculent precipitate was formed, and then dried to obtain crude polysaccharide from Undaria pinnatifida with a yield of 8.7%.

[0026] The above-mentioned undaria pinnatifida crude polysaccharide is dissolved in water, and according to the addition ratio of 0.01% of the weight of shredded tobacco, it is evenly sprayed on shredded tobacco in the cigarette feeding process, and made into cigarettes. After smoking, the smoke has no peculiar smell, the miscellaneous g...

Embodiment 3

[0028] Undaria pinnatifida was inactivated by infrared enzymes, washed clean, removed impurities, dried in the air, baked in an oven at 50°C for 4 hours, crushed and passed through a 40-mesh sieve, under ultrasonic conditions (frequency 100kHz), added 3 times the amount of water (m: m) Extract for 30 minutes, centrifuge the extract, filter the supernatant, concentrate the filtrate to 70% of the original filtrate, then add 3 times the volume of 95% ethanol, let it stand for 12 hours, filter out the crude polysaccharide flocs, and then dry , to get the crude polysaccharide from Undaria pinnatifida.

[0029] The above-mentioned undaria pinnatifida crude polysaccharide is dissolved in water, and according to the addition ratio of 0.05% of the weight of shredded tobacco, it is evenly sprayed on shredded tobacco in the cigarette feeding process, and made into cigarettes. After smoking, the smoke has no peculiar smell, the miscellaneous gas and irritation of the cigarette smoke are r...

Abstract

The invention discloses a preparation method of undaria pinnatifida rough polysaccharide, mainly comprising the following steps: a. drying and smashing pretreated undaria pinnatifida; b. taking a certain quantity of the undaria pinnatifida dry powder, and adding water fro extracting so as to obtain an undaria pinnatifida water extract; c. centrifuging, filtering and concentrating the extract; and d. adding ethanol into the concentrated solution, standing, filtering, and drying flocculent precipitate to obtain the undaria pinnatifida rough polysaccharide. The rough polysaccharide of the invention is dissolved with water to prepare feed liquid with different concentrations and is evenly sprayed on tobacco shreds according to 0.001-0.05 wt% of the tobacco shreds; sensing evaluation results show that after charged, cigarette smoke has no peculiar smell; the offensive taste and the pungency of the cigarette smoke are slightly lowered, after-sweet taste increases, quality of aroma is improved, aroma density is increased, and the smoking quality of the cigarette is improved, thus the invention has more practical production meanings and value and the application of the technology does not change the existing processing technic of the cigarette.

Description

technical field [0001] The invention relates to seaweed extraction and its application, especially the preparation method of undaria pinnatifida crude polysaccharide and its application in cigarettes. The application of this technology does not change the existing processing technology of the cigarette, and can improve the smoking quality and sensory comfort of the cigarette. Background technique [0002] Seaweed grows in the special environment of the ocean and contains special ingredients such as iodide, polyphenolic compounds, polyhalogenated terpenoids, sterols, polyunsaturated fatty acids and seaweed polysaccharides, and is also rich in protein, vitamins, and minerals Nutrients such as nutrients and trace elements have been initially developed and applied in food, industry, agriculture, medicine, beauty and health care, such as making seaweed noodles with fresh or salted seaweed plant powder, wheat flour, water and other seasonings . Because this kind of seaweed noodl...
