Preparation method of high-nicotine reconstituted tobaccos

Abstract

The invention provides a preparation method of high-nicotine reconstituted tobaccos. The preparation method of the high-nicotine reconstituted tobaccos and application thereof comprises the steps thatstage extraction by adopting ethanol aqueous solution of different concentrations, separation and concentration are conducted on remaining production concentrate to prepare stage concentrate pastes,stage extracts are returned to coating liquid in a coating feeding procedure of the reconstituted tobaccos, reconstituted tobacco bases are coated with the coating liquid before drying process, cutting and packaging are conducted to prepare the reconstituted tobaccos used for cigarettes. The method has the advantages of simple operation and lower cost, waste resources can be efficiently used to obtain products with higher added value, the products are returned to production and used, the reconstituted tobaccos prepared by means of the method has the advantages of high concentration and fragrance and has higher nicotine content, and nicotine content in the products can be adjusted according to demands of cigarette tobacco formula.

Description

technical field [0001] The invention belongs to the technical field of papermaking reconstituted tobacco leaves, and in particular relates to a preparation method of high-nicotine reconstituted tobacco leaves. Background technique [0002] In recent years, with the entry into force of the "Framework Convention on Tobacco Control" and the gradual expansion of the scope of smoking bans in public places around the world, coupled with consumers' increasing concern for their own health, the research and development of low-tar cigarette products has become increasingly important, but at the same time It is inevitable that the aroma and taste of cigarettes will decline. In China, with the introduction of the basic guidelines and strategic tasks of "upper cigarettes" and the in-depth advancement of work, especially the implementation of higher levels of brand development and technological innovation, the promotion of cigarette brand value, harm reduction, and product quality will be...

Problems solved by technology

[0004] Due to the high cost of the above-mentioned technologies, their large-scale use in the process of adding flavoring and flavoring to reconstituted tobacco leaves by the papermaking method is limited.

In the production process of reconstituted tobacco leaves by papermaking method, due to the limitation of production process and equipment conditions, there is a large amount of extraction concentrate remaining. This part of the remaining concentrate is usually composted with low-cost takeaway fertilizers or directly discharged into sewage The treatment plant treats it in the form of waste liquid, which leads to the loss of a large amount of aroma components in the concentrated liquid, which is not conducive to the control of production costs and the utilization of waste resources

Effective recovery and enrichment of active ingredients, especially nicotine, in the remaining concentrate from the production of reconstituted tobacco leaves can be returned to production to obtain high-nicotine and high-aroma reconstituted tobacco leaf products.
