Tobacco extract, extracting method and application

Abstract

The invention discloses a tobacco extract, an extracting method and application and belongs to the field of tobacco additives. The tobacco extract is extracted with the method including the following steps that firstly, propylene glycol is added into tobacco raw materials, and then baking is carried out after standing; secondly, smashing is carried out, and a solvent is added into powder materials for extraction; thirdly, extract liquid passes through an ultrafiltrtion membrane, penetrating liquid is obtained and subjected to reduced pressure distillation, and concentrate is obtained; fourthly, the concentrate is subjected to secondary separation with a molecule distillation method, light components are collected, and the tobacco extract is obtained. The extract contains rich megastigmatrienone, Damascone, neophytadiene, phenylcarbinol, phenethyl alcohol, farnesylacetone and pyrone and furanone aroma components, and the tobacco extract is thick in baking aroma and tobacco aroma, good in penetration, small in irritation and miscellaneous gas, high in satisfaction, capable of improving the smoking quality of cigarettes and providing a certain amount of nicotine to meet the physiological needs of consumers when used.

Description

technical field [0001] The invention relates to a tobacco extract, and also relates to an extraction method and application, belonging to the field of tobacco additives. Background technique [0002] Tobacco stems, the main veins of tobacco leaves, account for about 25% to 30% of the weight of tobacco leaves. my country is a big tobacco producing country, producing about hundreds of thousands of tons of tobacco stems every year. Among them, some tobacco stems are manufactured by expansion technology into expanded stems and added to the leaf group formula, and some tobacco stems and waste tobacco leaves (fragments, tobacco powder) are added with wood pulp as raw materials to make reconstituted tobacco leaves. Using a certain proportion of expanded cut stems and reconstituted tobacco leaves in the cigarette leaf group formula can reduce the tar release and increase the filling value of cigarettes. However, shredded stems and reconstituted tobacco leaves have heavy miscellane...

Problems solved by technology

At present, most commercially available tobacco extracts are prepared by ethanol continuous extraction method, which has two major disadvantages: ① part of the natural aroma is lost during the extraction process, and the aroma of the product is weak; ② in addition to aroma components, there are also pectin in the product , protein, and hemicellulose substances, these substances will be cracked during the smoking process of cigarettes to produce some harmful components, and at the same time increase the irritation and miscellaneous gas of smoking, and affect the sensory quality (Song Peng. Microbial fermentation reduces harmful substances in cigarette smoke Composition and research on improving cigarette quality [D]. Xi'an: Northwest University, 2008.; Chi Jingji, et al. Correlation analysis between main chemical indicators of tobacco leaves and smoking quality [J]. Journal of Agricultural Sciences of Yanbian University, 2006, 28(3):208-210.)

However, when water is used as the extraction solvent, small and medium polar aroma components cannot be fully dissolved. On the contrary, components that are unfavorable to cigarette smoking such as pectin, protein, and polysaccharides are extracted, and the enzymatic hydrolysis is carried out under acidic conditions....
