Aroma-enhancing puffed tobacco stem particles and preparation method and application thereof

Abstract

The invention discloses aroma-enhancing puffed tobacco stem particles and a preparation method and application thereof. The preparation method of the aroma-enhancing puffed tobacco stem particles comprises the steps that a micropore structure is formed in each tobacco stem, and the tobacco stems are dried and smashed after being fixed and formed to form particles; the tobacco stem particles are inoculated with a compound aroma-generating microorganism, fermental cultivation and drying are carried out on the tobacco stem particles and the compound aroma-generating microorganism, and then the aroma-enhancing puffed tobacco stem particles can be obtained. The compound aroma-generating microorganism is formed by compounding bacillus subtilis, Trichoderma reesei, Aspergillus niger and Hansenula polymorpha according to the wet-cell mass ratio of 5:2:1:1. According to the aroma-enhancing puffed tobacco stem particles and the preparation method and application thereof, the tobacco stems serve as raw materials to be processed to obtain the puffed tobacco stem particles, then the compound aroma-generating microorganism is added, and serving as a filter material of a filter tip, the finally-obtained aroma-enhancing puffed tobacco stem particles have the advantages of being high in filter efficiency, strong in adsorption capacity, free of offensive odors and consistent with tobacco in aroma and have good application prospect.

Description

technical field [0001] The invention relates to the field of cigarette processing, in particular to a flavor-enhancing puffed tobacco stem particle and a preparation method and application thereof. Background technique [0002] Tobacco is a plant of the Solanaceae Nicotiana, and the stems are the thick and hard veins of the tobacco leaves, accounting for about 25%-30% of the total weight of the tobacco leaves. Tobacco stems are by-products of the tobacco industry and are currently mostly disposed of. my country is a big tobacco country. Every year, hundreds of thousands of tons of tobacco stem resources are discarded, which not only causes environmental pollution, but also wastes natural resources. However, if it is used in cigarette production, if it is not properly treated, it will reduce the aroma of cigarettes and reduce the quality of cigarettes. [0003] In the 1960s, filter cigarettes came into being, which effectively reduced the amount of tar and nicotine in cigar...

Problems solved by technology

Although the above-mentioned diatomite, activated carbon, and loess plastic particles can improve the filtering and adsorption effects of the filter, the composite filter made of these filter materials still has the following deficiencies: (1) due to the high strength of these materials, in the filter During the slitting after rod forming and the cigarette rolling slitting process, the slitting blade wears a lot, resulting in an increase in equipment costs and an increase in downtime accidents; (2) Due to the lack of toughness of these materials, during the cigarette manufacturing and transportation process It is easy to produce dust due to wear and tear. On the one hand, these dusts will enter the smoker's mouth with the smoke, endangering health. On the other hand, the dust mixed in the smoke will cause cigarettes to produce different degrees of miscellaneous gas, such as "earthy smell" , "charcoal smell", etc.; (3) The unqualified cigarettes that appear in the cigarette production process are easily polluted by the above-mentioned materials during the recycling process, so the unqualified products of composite filter stick cigarettes made of these filter materials , generally cannot be recycled, which seriously causes the loss of tobacco leaf raw materials; (4) because these materials are "foreign objects", even if sprayed with tobacco spices, there will inevitably be a loss of odor during the filter molding process, which cannot be well processed. Maintain consistency with the smell of tobacco leaves

[0007] The Chinese patent "A Preparation Method and Equipment for Expanded Tobacco Stem Granules" (Application No.: 200710065892.3) proposes a new method for preparing expanded tobacco stem granules. The expanded tobacco stalk granules produced by this patent effectively solve the above problems The first three points, but the fourth point has not been effectively resolved
