Description
Technical field
The invention belongs to tobacco manufacture field, be specifically related to a kind of method that reduces benzo [a] pyrene burst size redrying and alcoholization in cigarette smoke.
Background technology
Benzo [a] pyrene is a kind of typical condensed-nuclei aromatics (being called for short PAH) in flue gas.Condensed-nuclei aromatics is tobacco unburnt product under high temperature anoxia condition.The organic matter fragment that various organic matter pyrolysis generate, forms through complicated polymerization process.In flue gas, the kind of condensed-nuclei aromatics has more than hundred kinds, in cigarette smoke, identified about 30 kinds of condensed-nuclei aromatics that have a carcinogenicity, wherein the most typical is exactly benzo [a] pyrene, and its carcinogenicity is the highest, next is the condensed-nuclei aromatics such as dibenzo [a, h] anthracene, benzo [b] firefly anthracene.2009, by the Zhengzhou tobacco research institute cigarette smoke harmfulness index that has carried out Chinese-style cigarette of taking the lead, studied, in 29 kinds of harmful components of cigarette mainstream flue gas, filtered out 7 kinds of representative compositions as cigarette Evaluation of Harmfulness index, benzo [a] pyrene is wherein one.Therefore the research that, reduces benzo [a] pyrene burst size in cigarette smoke to improving cigarette quality, to improve smoking property of cigarette security significant.
Tobacco leaf is the primary raw material of producing cigarette, after beating and double roasting and alcoholization, tobacco leaf is allowed for access the suitability for industrialized production stage, existing beating and double roasting technology mainly focuses on improving tobacco leaf physical arrangement after beating and double roasting, chemical composition uniformity etc., as: Yang Kai etc. are take nicotine as parameter, carry out the research of tobacco beating double-roasting formula uniformity (based on the research of tobacco beating double-roasting formula uniformity control model, 2012,12), the finished product sheet cigarette nicotine content coefficient of variation mean value of formula module under each control model is all controlled at below 4%; Zhang Qilong etc. adopt correlation analysis method, have studied the relation (correlation of beating and double roasting process tobacco leaf character, quality index and piece rate, 2011,3) of tobacco leaf routine chemical components, physical index and quality index and piece rate in beating and double roasting process.Tobacco mellowing is to improve quality of tobacco, the requisite link of raising tobacco leaf usability.Prior art mainly concentrates on the additional means such as the variation tendency research of the related substanceses such as chemical composition in alcoholization process, enzyme and blade face microorganism, different alcoholization conditions and environment and alcoholization quality correlation research, biologic product and is applied to and promotes after tobacco mellowing aesthetic quality and shorten the alcoholization phase etc.Chinese patent ZL200410040526.9 discloses a kind of by adding enzyme preparation application in beating and double roasting process at beating and double roasting, can accelerate the natural alcoholization speed of tobacco leaf, shorten the alcoholization cycle, improve blue foreign smell and excitant in tobacco leaf, there is the effects such as humectation and mildew-resistant.The application number that Chinese patent is announced is: 201310092968.7 patent of invention has proposed a kind of method of utilizing Pelargonium roseum to carry out tobacco mellowing blending, utilize this process of growing of tobacco mellowing, in closed environment, allow tobacco leaf fully absorb Pelargonium roseum fragrance, increase tabacco fragrance, promote tobacco leaf entirety aesthetic quality.How to reduce benzo in cigarette smoke [a] pyrene burst size, reduce the harm of smoking to health, have in recent years much research.This type of research is mainly the cigarette filter of making by special material or in cigarette, adds additive to reduce benzo [a] the pyrene content in cigarette smoke.The patent of invention that the application number of being announced as Chinese patent is 200910263548.4 has proposed a kind of composite filter tip that contains biological composition, adopts this filter tip can obviously reduce benzo [a] the pyrene burst size in cigarette smoke.The adsorbent that the invention that the application number that Chinese patent is announced is 201110180023.1 provides a kind of effective absorption consisting of porous carbon materials to comprise tar ingredients contained in tobacco and benzo [a] pyrene etc.; More than study aspect reducing the effect of benzo [a] pyrene burst size in cigarette smoke and obtained better effects, but for tobacco threshing and redrying and alcoholization processing technology, to reduce benzo [a] pyrene burst size in cigarette smoke, paid attention to, also had no relevant patent and bibliographical information.Therefore, reduce a kind of redrying and the alcoholization method of benzo [a] pyrene burst size in cigarette smoke, guaranteeing under the prerequisite of raw tobacco material product style, will reduce benzo in cigarette smoke [a] pyrene burst size and move forward to beating and double roasting and alcoholization process, for mentioning safety cigarette, having important value.
Summary of the invention
The object of this invention is to provide a kind of method that reduces benzo [a] pyrene burst size redrying and alcoholization, the method adds the biologic product that extracts in tobacco, separates that can reduce benzo [a] pyrene burst size in multiple cured tobacco leaf, the leaf Cased strips redrying procedure technology parameter of simultaneously fighting each other rationally arranges, can effectively reduce benzo [a] the pyrene burst size in cigarette smoke, thereby contribute to alleviate the harm of smoking to human body.
In order to reach above-mentioned technique effect, the present invention takes following technical scheme:
A kind of method of benzo [a] pyrene burst size redrying and alcoholization in reduction cigarette smoke, comprise smoked sheet multiple roasting operation and alcoholization operation, described alcoholization operation is to add alcoholization agent in the tobacco leaf after redrying, described alcoholization agent is the biologic product aqueous solution, and described biologic product is one or more in bacillus subtilis, bacillus megaterium, Bacillus circulans, bacillus amyloliquefaciens freeze-dried vaccine powder.
