Description

Deep processing method of natural fragrant raw material for cigarettes and application of natural fragrant raw material in novel tobacco

Technical Field

The invention belongs to the technical field of deep processing methods of natural fragrant raw materials, and particularly relates to the technical field of application of products of the natural fragrant raw materials in novel tobacco on the basis of the technical base of the deep processing methods of the natural fragrant raw materials.

Background

The research and development of novel tobacco products is one of the most recently determined major special items of the national tobacco special agency, and is also an important direction of future development of the tobacco industry. The heating non-burning cigarette is characterized in that a special heat source is used for heating tobacco materials and then releasing smoke, the tobacco materials are heated only and are not burnt, potential harmful substances generated by pyrolysis of the tobacco due to high-temperature combustion are reduced, and the harmful components of main stream smoke are reduced. The smoking temperature of the heated non-combustible cigarette is much lower than that of the traditional cigarette (generally about 350 ℃), the action of the aroma substances and the aroma generating mechanism are different from those of the traditional cigarette, the aroma is only generated by distillation and simpler pyrolysis reaction, and the satisfaction and tobacco aroma still have a larger difference than those of the traditional cigarette.

In theory, proper essence and spice are added into the heated non-combustible cigarettes to make up for the defect of insufficient aroma, improve the characteristics of smell and taste, improve the quality of the cigarette products and endow the cigarette products with new characteristics.

The tobacco dry distillation fraction spice prepared by the dry distillation method can keep the original tobacco taste, has soft scorched color and smell, meets the basic requirement of flavoring, has no pollution to the environment compared with a smoking method, and does not contain strong cancerogenic substances such as 3, 4-benzopyrene and the like. The dry distillation spice can be applied to the field of novel tobacco, can make up for the defects of the novel tobacco in the aspects of comfort, smoke characteristics (fine and smooth, stiff), flavor style (richness, flavor) and the like, and has wide application prospect in the tobacco spice industry.

However, in the conventional carbonization method, the sample is heated at high temperature under the condition of air isolation, black tobacco oil is generated by heating and carbonization under the condition of no oxygen, the smoky flavor is too heavy, the tobacco raw material is easy to be burnt, the carbonized product has strong burnt bitter taste, and the side effects of uncomfortable taste, rough feel and the like are brought while the tobacco flavor is increased. Such as: 1. the burning and cracking temperature of the traditional cigarette approaches 900 ℃, the using temperature of the heated non-burning cigarette is about 350 ℃, and the smoking process is similar to a low-temperature carbonization process. Under lower heating temperature, tobacco flavor substances can not be fully combusted and pyrolyzed, traditional tobacco essence and spice are directly added into the heated non-combusted cigarettes for flavoring, so that the richness of tobacco flavor and the shortage of fragrance strength can be caused during smoking, green gas and miscellaneous gas can be mixed in the smoke, the baking flavor is not obvious, and the smoking effect is poor.

2. The traditional dry distillation method uses tobacco primary raw materials such as tobacco leaves, cut tobaccos and the like to prepare dry distillation spice through direct heat treatment, only generates simple thermal cracking reaction, and has single type of aroma production reaction. The condition of direct solid-phase heating of the carbonization reaction is difficult to control, the interior of the reaction system is heated unevenly, the tobacco raw materials are easy to be coked to cause burnt smell, the carbonization spice burnt smell is too heavy, and the aroma comfort is poor. In addition, the aroma of the tobacco materials subjected to carbonization treatment has a certain difference with the quality of the aroma of the actual tobacco leaves, and the tobacco materials are required to be further extracted and processed, and then masking agents or deodorizing treatment is added, so that the method has the advantages of multiple operation procedures and difficult industrialization.

3. The preparation cost of dry distillation treatment by using the tobacco primary raw material is high. The tobacco primary raw materials such as cut tobacco or tobacco leaf are fluffy in texture, the filling volume in a container is large, the dissolution rate of aroma components is low, a large amount of tobacco raw materials are needed to be used for preparing a small amount of dry distillation spice, and the yield is low.

As disclosed in some prior patents:

the invention application with publication number of CN108893195A discloses an essence formula suitable for heating non-combustible cigarettes, which consists of tobacco extract, tobacco essence, glyceryl triacetate, glycerol, propylene glycol and tobacco powder.

The invention application with publication number of CN109512015A discloses a heating non-burning solid essence for cigarettes and a preparation method thereof, wherein the heating non-burning solid essence contains natural extract, microcrystalline cellulose, sodium carboxymethylcellulose and a fuming agent.

The invention application with publication number of CN110655985A discloses a flavoring with Chinese flue-cured tobacco characteristic fragrance and a heated non-combustible cigarette prepared from the flavoring, wherein the flavoring comprises the following components: burley tobacco absolute, aminosugar reactant, dried orange peel flower extract, gynostemma pentaphylla extract, ethyl maltol, guaiacol, 5-methyl furfural, 2-acetyl pyrazine, 2, 3-dimethyl pyrazine, glycerin and ethanol.

Most of traditional spice substances are compounds with lower molecular weight, low boiling point and stronger volatility, if the traditional spice substances are directly added into the heated nonflammable cigarettes to be used as flavoring treatment, the defects of serious aroma loss, rich smoke aroma and insufficient aroma strength of the spice in the high-temperature processing process are caused, and the traditional spice substances are heavy green gas and miscellaneous gas and are not suitable for heating the nonflammable cigarettes.

Therefore, a functional essence spice capable of improving the sensory quality of the heating non-combustible cigarette is developed, and has important significance for developing heating non-combustible cigarette products.

Disclosure of Invention

Further, the method is used for obtaining one or more of furan, pyran substances, phenol substances and ketone substances after treatment.

Further, the furan and pyran substances obtained after the treatment by the method are as follows: furfuryl alcohol, furfural, 5-methylfurfural, 2, 3-dihydro-3, 5-dihydroxy-6-methyl-4 (H) -pyran-4-one);

the phenolic substances are phenol, catechol, guaiacol and 4-ethyl guaiacol;

2) The deep processing spice has smoke and baking aroma on the smell aroma, but has no burnt smell and green gas; the tobacco extracts such as flue-cured tobacco, aromatic tobacco and the like are rich in water-soluble sugar and reducing sugar, can generate thermal cracking and caramelization reaction, and have more flue-cured and smoked smell than the primary raw materials. Reducing sugar in other natural extracts can also react with amino acid substances in tobacco through Maillard reaction, so that the aroma is more excellent;

3) The volatile components of the deep processing spice are characterized in that: the deep-processing spice is subjected to gas chromatography mass spectrometry, the percentage of low-boiling-point small-molecule aroma substances in the volatile components of the deep-processing spice is 10% or more higher than that of the low-boiling-point small-molecule aroma substances in the raw material of the raw tobacco aroma, and the deep-processing spice has obviously increased substances which directly contribute to the burnt sweet aroma of the smoke: the content of furan and pyrans (such as furfuryl alcohol, furfurol, 5-methylfurol, 2, 3-dihydro-3, 5-dihydroxy-6-methyl-4 (H) -pyran-4-one) is obviously increased, and phenols with smoke aroma (such as phenol, catechol, guaiacol, 4-ethylguaiacol) and ketones (solanone, beta-damascenone) which can enrich smoke aroma components are also found.
