Embodiment 1

[0039] Take 830 g of fresh yam, wash, cut into thin slices, and dry at 50°C to obtain 235 g of dried yam, which is crushed to about 20 mesh; add 10 times the amount of 80% ethanol, heat and reflux for extraction for 2 h, filter through 400 mesh Cloth filtration to obtain about 2150 mL of the extract; use a rotary evaporator to concentrate under reduced pressure, the vacuum degree is controlled in the range of -0.090 to -0.095 MPa, the temperature of the water bath does not exceed 50 ° C, and it is concentrated to 50% of the original volume to obtain the present invention. Yam alcohol extract.

[0040] The slag after alcohol extraction was extracted twice with water, the solid-to-liquid ratio was 1:10 and 1:5 in turn, the temperature was 83°C, and each extraction was 2 h; the two extractions were combined to a total of 2600 mL, and concentrated to 600 mL under reduced pressure Slowly add it to a beaker filled with 2000 mL of 95% ethanol, and keep stirring; then place it at 5°C ...

Embodiment 2

[0044]Take 500 g of dried yam powder, extract with 90% ethanol at 70°C for 2 hours, the solid-to-liquid ratio is 1:10, and filter to obtain about 4600 mL of extract; concentrate under reduced pressure to about half of the original volume Promptly get the yam alcohol extract of the present invention.

[0045] The slag after alcohol extraction was extracted twice with water, the solid-to-liquid ratio was 1:10 and 1:6 in turn, the temperature was 75°C, and the extraction time was 3 hours each time; the two extractions were combined to a total of 5900 mL, and concentrated under reduced pressure to 2500 mL .

[0046] Take out 1300 mL concentrated water extract, add 2500 mL deproteinization reagent (chloroform-n-butanol 4:1 mixture), stir and shake for 30 min, discard the denatured protein; add 1300 mL deproteinization reagent to the supernatant and repeat Operate once. The deproteinized supernatant was about 800 mL, concentrated under reduced pressure to about 400 mL, and slowly ...

Embodiment 3

[0049] The application of yam alcohol extract of the present invention and yam polysaccharide (taking the product of embodiment 1 as example):

[0050] Weigh 0.010 g of yam alcohol extract, add 70% ethanol to dilute to 1.000 g, mix well, add 4 μL of yam alcohol extract diluent to each blank reference cigarette (flavoring amount is 0.05 ‰), placed in a constant temperature (22±1°C) constant humidity (relative humidity 60±2%) box to balance for more than 48 hours.

[0051] Weigh 0.005 g of yam crude polysaccharide, add distilled water to 5.000 g, and spray it evenly on 100 g blank shredded tobacco with a micro sprayer after it is completely dissolved (adding amount is 0.05 ‰). Put the shredded tobacco into a sealed bag, place it in an oven at a constant temperature of 80°C for 30 minutes, then shake the shredded tobacco quickly to keep the moisture content of the shredded tobacco at about 12%, roll it into cigarette sticks, and put it in a constant temperature and humidity box u...

Abstract

The invention discloses an application of Chinese yam extractives in cigarettes. The Chinese yam extractives are prepared according to the method that a. a fresh Chinese yam is washed, cut into slices, dried and smashed; b. the Chinese yam is extracted and condensed through ethyl alcohol with the certain concentration to obtain Chinese yam alcohol extraction liquid; c. material residues after alcohol extraction are further extracted through water; d. after water extraction liquid is filtered and condensed, ethyl alcohol is added to the water extraction liquid, precipitating, standing and filtering are conducted, and precipitates are dried to obtain Chinese yam crude polysaccharide; e. deproteinization and purification are conducted. When being applied in a cigarette perfuming link, Chinese yam alcohol extraction liquid can improve perfuming quality, cover sundry flavors, increase clean aroma and sweet aroma, ensure that smoke is more delicate, and improve cigarette smoking and absorbing comfort. After being dissolved in water and used as cigarette material liquid, the Chinese yam crude polysaccharide plays a role in thickening smoke, reducing stimulation and improving mouthfeel, and can reduce the amount of harmful ingredients such as cigarette smoke free radicals. The application of the Chinese yam extractives in the cigarettes does not change the previous performance and the previous processing processes of the cigarettes, improves perfume quality of the cigarettes and sense organ comfort of cigarette smoking, and also has practical production significance and value.

Description

[0001] technical field [0002] The invention relates to plant extraction and its application, in particular to the application of a yam extract in cigarettes, including the step-by-step extraction of yam alcohol extract and 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 [0003] As the tar content of domestic cigarette products continues to decrease, problems such as reduced cigarette aroma, weakened style characteristics, and poor comfort have been caused to varying degrees. In order to improve the overall quality of cigarette products, the development of new flavors for tobacco with remarkable effect and stable quality is a main solution. Among them, natural flavors have become the focus of research and development in recent years because of their rich fragrance, vivid fra...
