High-nicotine tobacco extract and application thereof

Abstract

The invention discloses a high-nicotine tobacco extract and application thereof, and belongs to the field of tobacco additives. The extract is rich in aroma components such as megastigmatrienone, damascone, pyrones and furanones in tobacco, can provide tobacco aroma and roasting aroma, further contains certain nicotine, can cater for physiological needs of consumers, and improves satisfaction. Content of macromolecular substances such as proteins, pectin and polysaccharides in the extract is extremely low, solubleness is good, the high-nicotine tobacco extract can be completely dissolved into MCT (medium chain triglyceride), and can be used for perfuming a filter tip. Besides, the high-nicotine tobacco extract is added into cut stems or reconstituted tobaccos, so that stimulus can be reduced, strength is improved, a blending rate, in a tobacco group, of the cut stems or reconstituted tobaccos is increased, and content of cigarette tar is reduced while fragrance is invigorated and impurities are covered.

Description

technical field [0001] The invention relates to a high-nicotine tobacco extract and the application of the extract, 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 miscellaneous gases...

AI Technical Summary

Problems solved by technology

Among them, the commonly used solvent for the capsule method is medium-chain triglyceride (MCT), which has low polarity, and the commercially available tobacco extract has complex components, including a large amount of macromolecular substances such as sugars and proteins, so it is difficult to extract Soluble in MCT, thus prone to loss of some aroma components

Moreover, these macromolecular substances may affect the plasticity of the tow, make the fibers bond and block the mainstream smoke passage, and affect the fragrance penetration.

[0004] At present, commercially available tobacco extracts are mostly extracted with different concentrations of ethanol as a solvent, but this method has two major disadvantages: ① Some natural aroma components are lost during the extraction process, and the aroma of the product is weak; ② In addition to the aroma components in the product, , as well as pectin, protein, and hemicellulose substances. These substances will be cracked to produce some harmful components during the smoking process of cigarettes. Research on Harmful Components in Cigarette Smoke and Improvement of Cigarette Quality[D]. Xi'an: Northwest University, 2008.; Chi Jingji, et al. Correlation Analysis between Main Chemical Indexes of Tobacco Leaf and Smoking Quality[J]. Yanbian University Journal of Agricultural Sciences, 2006,28(3):208-210.)

However, ethanol and water are highly polar solvents, and the obtained extracts are mainly composed of highly polar and non-volatile components. In addition, high-temperature heating and extraction will easily cause the loss of some heat-sensitive and volatile aroma components. Even if molecular distillation technology is used to separate and enrich Light components, but the small and medium polar aroma components lost in the early stage can no longer be made up
