Embodiment 1
[0023] 1. Take the fresh leaves of aloe vera, rinse them with deep well water, dry them in the air, and after 6 minutes of ultraviolet sterilization, use a high-speed pulverizer to crush the fresh leaves of aloe vera into a thin slurry. Then use a high-speed sedimentation machine for precipitation treatment. Then filter or vacuum filter to become pure aloe juice.
[0024] 2. Use water with a volume ratio of 1:2, microwave extraction for 10 minutes, filter the extract and centrifuge it in an industrial centrifuge at 1000 rpm for 15 minutes, take the supernatant and concentrate it to 1 / 10 of the original volume;
[0025] 3. Add the concentrated supernatant to 95% ethanol, stir for 5 minutes, let stand for 2 hours, filter and recover the ethanol, collect and precipitate the crude polysaccharide of aloe, wash the filter cloth with water for 3 times, and combine the washing liquid with the crude polysaccharide. Stir and dissolve to obtain a crude polysaccharide aqueous solution, f...

[0030] 1. Take the fresh leaves of aloe vera, rinse them with deep well water, dry them in the air, and after 8 minutes of ultraviolet sterilization, crush the fresh leaves of aloe vera into a thin slurry with a high-speed pulverizer. Then use a high-speed sedimentation machine for precipitation treatment. Then filter or vacuum filter to become pure aloe juice.
[0031] 2. Use water with a volume ratio of 1:3, microwave extraction for 20 minutes, filter the extract and centrifuge it in an industrial centrifuge at 2000 rpm for 15 minutes, take the supernatant and concentrate it to 1 / 20 of the original volume;
[0032] 3. Add the concentrated supernatant to 98% ethanol, stir for 8 minutes, let stand for 3 hours, filter and recover the ethanol, collect and precipitate the aloe crude polysaccharide, wash the filter cloth with water for 3 times, and combine the washing liquid with the crude polysaccharide. Stir and dissolve to obtain a crude polysaccharide aqueous solution, filter...

Abstract
The invention discloses an extracting method of aloe polysaccharides, and the application thereof in cigarettes, wherein, the extracting method comprises the following steps: (1) fresh aloe leaves are crushed, centrifuged and filtered to obtain pure aloe raw juice; (2) after going through the steps of microwave extraction, centrifugal separation and concentration, water is added into alcohol, mixed, rested and filtered and crude aloe polysaccharides is obtained by settlement collection; (3) the filtrate goes through a nanofiltration membrane and an ultrafiltration membrane respectivcely for nanofiltration and ultrafiltration and then is frozen and dried; and (4) after being dissolved by water, the aloe polysaccharides is applied to tobacco shreds during a feeding process in a spraying manner so as to improve the moisturizing effect of the cigarettes; when being smoked, the dry sensation of the cigarettes is reduced, no undesirable odor exists in the smoke and the saliva of smokers is enriched. The extracting method has the obvious advantages that: the smoking quality of the cigarettes is improved; the content of harmful substances in the smoke is reduced; the sweetness and comfort are improved; the effects of enriching saliva and moisturizing are significant; and the application of the technology does not change the processing techniques of the existing cigarettes and has significance and value in the actual production.
Description
technical field [0001] The invention relates to the extraction and application of plants, in particular to the extraction method of aloe polysaccharide and its application in tobacco. The application of this technology does not change the existing processing technology of the cigarette, and can improve the smoking quality of the cigarette. Background technique [0002] With the rapid development of my country's economy, cigarette consumers have higher and higher requirements for the inherent quality of products. However, compared with the requirements of consumers, various domestic cigarette products still have quality defects to varying degrees, such as weak aroma and lack of plumpness. , The aroma characteristics are not obvious, the smoke is dry, spicy, throat-piercing, not sweet enough, and the comfort is poor. It is an inevitable trend in the development of cigarettes to reduce the dry feeling of cigarettes and improve the smoking quality of cigarettes. [0003] Aloe v...
