Tobacco additive for increasing smoke concentration and preparation method and application thereof

Abstract

The invention relates to a tobacco additive for increasing smoke concentration and a preparation method and application thereof. Shortleaf kyllinga herb, lysimachia foenum-graecum and murraya kwangsiensis are used as main raw materials. The preparation method comprises the following steps: soaking a raw material mixture in an organic solvent or performing reflux extraction for 1 to 360 hours; leaching the mixture by using qualitative filter paper and filtering off residues to obtain natural tobacco additive extracting solution; performing concentration on the extracting solution under reduced pressure in a water bath at the temperature of between 50 and 80 DEG C; recycling a solvent of the extracting solution to obtain a natural tobacco additive; dissolving the tobacco additive in a certain amount of single or mixed solution consisting of water, ethanol and propylene glycol; and spraying the mixture accounting for 0.005 to 2.5 percent of the weight of cigarette cut tobacco, cut stems or thin tobacco slices onto sample cut tobacco according to the conventional flavoring process. The tobacco additive can remarkably enrich tobacco flavor, effectively increase the smoke concentration of the cigarette, enhance sweet feeling in an oral cavity and achieve fine and soft smoke. The additive has the advantages of simple preparation process, low cost and wide market prospect.

Description

technical field [0001] The invention relates to a smoke additive for increasing smoke concentration, a preparation method and application thereof. Background technique [0002] The Outline of the Medium and Long-term Science and Technology Development Plan of the Tobacco Industry points out that reducing the harmfulness of cigarettes is an effective measure for the tobacco industry to respond to the challenges of WTO and WHO and improve the core competitiveness of Chinese-style cigarettes. Carrying out research on cigarette harm reduction technology is a key link to establish the advantages of Chinese-style cigarettes and enrich the theoretical and technical connotations of Chinese-style cigarettes. reflect. In recent years, the State Tobacco Monopoly Administration has established the product development principles of "high aroma, low tar, and low harm" for Chinese-style cigarettes. One of the measures to reduce the harm of cigarettes is to reduce the tar and nicotine cont...
