Embodiment 1

[0030] The extraction method of white fungus crude polysaccharide and its application in tobacco, wherein the white fungus crude polysaccharide in the present invention is obtained by the following method:

[0031] a. Tremella is pre-treated: take the tremella, wash it with fresh water, remove impurities, and dry it in the air or in the sun;

[0032] b. Drying and crushing: after drying the pretreated white fungus at a temperature of 50°C, crush it to 40 meshes;

[0033] c. Under the condition of ethanol reflux, extract the white fungus with absolute ethanol for 2 hours;

[0034] d. Filter the extract, and extract the white fungus with water for 3 hours at 70°C;

[0035] Concentrate the filtrate after filtering Tremella extract until the content of dry matter is 5%, add the concentrated filtrate according to the volume ratio of filtrate: absolute ethanol is 1:4, mix and stand still for more than 48h, after filtering, both obtained Tremella crude polysaccharide of the present...

Abstract

The invention discloses an extraction method of tremella polysaccharide and an application of the tremella polysaccharide in tobaccos. The method comprises the following steps of: a. after pre-processing tremella, drying the tremella at 30-80 DEG C and then grinding the tremella to 40-100 meshes; b. soaking the tremella powder in 80-100% ethanol for 1-24 hours; c. extracting the tremella powder with water for 1-4 hours at 50-100 DEG C; d. concentrating the filtrate obtained after filtration; and e. adding the concentrate to absolute ethyl alcohol to a scale, carrying out static precipitation for more than 24 hours and obtaining the tremella polysaccharide after filtration. The extraction method has the following beneficial effects that the tremella polysaccharide is added to cut tobaccos as feed liquid for tobaccos, so when the cigarettes burn, the smoking quality of the cigarettes can be obviously improved, the aroma quantity is increased, the irritation and the dry sensation are reduced and the taste is improved; the tremella polysaccharide also has a certain moisture preserving function and can reduce the contents of such harmful components in the main stream smoke of the cigarettes as free radicals; and the tremella polysaccharide does not change the original performances of the cigarettes or the existing processing techniques of the cigarettes, so the tremella polysaccharide further has practical production significance and value.

Description

technical field [0001] The invention relates to white fungus crude polysaccharide and its application in tobacco. The application of this technology does not change the existing processing technology of cigarettes, can improve the sensory quality of cigarettes, and reduce the harmfulness of cigarettes. Background technique [0002] As the problems of smoking and health attract more and more attention, it is an inevitable development trend of cigarettes to improve the smoking safety of cigarettes, increase health care functions, and reduce harmful components in cigarette smoke. Therefore, as soon as varieties such as ginseng cigarettes and peppermint cigarettes appear on the market, materials such as ginseng and peppermint are added in shredded tobacco with unique health care functions or tastes. [0003] Tremella has a long history of medicinal and edible in our country, tremella crude polysaccharide can be extracted from tremella. Tremella has the functions of increasing ...
