Description
Technical Field
The invention relates to the technical field of cigarettes, in particular to a solvent-heating tobacco original spice and a preparation method thereof.
Background
The tobacco leaves are modulated and naturally fermented, and although the smoking quality is greatly improved, the fragrance has some defects. In order to keep the relative stability of the quality of cigarette products, the flavor defect is overcome by adding essence and spice substances for smoking while reasonably designing a leaf group formula, namely, the flavoring is also an important measure for improving the quality of the products. The cigarette flavoring can supplement elegant fragrance, endow the cigarette with unique characteristic fragrance, and coordinate fragrance, so that different types and grades of tobacco fragrance are combined and coordinated with each other organically. Covering up or diluting miscellaneous qi. The cigarette can also increase the sweetness, improve the smoking taste, lighten the irritation of smoke and weaken some miscellaneous gas by adding the fragrance, thereby improving the quality.
With the rapid development of the tobacco industry in China, the formation of large brands, the requirement of reducing tar and harm of cigarettes and the further improvement of tobacco products, the demand of essence and spice for high-quality cigarettes is increasing day by day. Generally, the perfume is classified into two categories, i.e., natural perfume and synthetic perfume, according to the source of the perfume, 3000 kinds of natural perfume are known, 7000 kinds of synthetic perfume are more known, and new varieties are still emerging. Among them, the flavors developed from the original sources of tobacco leaves have been considered as a class of products having the best harmony with smoke.
In recent years, the non-burning cigarette is more and more popular abroad, and once in Japan, the non-burning cigarette occupies about 35 percent of the cigarette consumption market. Because the main components of the smoke of the heating non-combustible cigarette are glycerin and propylene glycol, and the heating temperature is lower, the sensory quality of the smoke is greatly different from that of the traditional cigarette, and the consumers of the two products can hardly communicate with each other. However, the cigarette which is not burnt after being heated has certain advantages in certain aspects, such as small smoke irritation and better moistening feeling.
Based on the reasons, how to increase the smoke smell of the cigarette which is not burnt after being heated in the traditional cigarette and form better harmony with the smoke is a difficult problem which needs to be solved by the traditional cigarette enterprises to face new situation at present.
Disclosure of Invention
The invention aims to provide a preparation method of a solvent-heated tobacco original spice, which can increase the special smoking taste of a cigarette which is not combusted when being heated in the traditional cigarette, reduce the irritation of smoke, improve the moist feeling and increase the smoke quantity.
The invention is realized by the following technical scheme: adding glycerol-propylene glycol as solvent into aged tobacco leaf, carrying out co-heating reaction with tobacco leaf in a closed system completely, and separating the solvent part, wherein the solvent is the required spice and can be added into the filter tip or tobacco shred during the filter tip processing process.
The technical scheme is greatly different from the prior common solvent extraction and thermal cracking aroma production technology:
1. the glycerol-propylene glycol as the solvent is a part of the characteristic smoking taste in the spice, and if the spice in the solvent is extracted, the effect of simulating the smoking taste of a cigarette which is not burned by heating cannot be achieved;
2. compared with common conventional extraction solvents such as water, ethanol, organic solvents and the like, the glycerol-propylene glycol system solvent has an atomization reflux effect, and the characteristic is favorable for capturing aroma components in a closed co-heating system by liquid fog drops, so that the retention rate of small molecular substances with high aroma values is greatly improved (generally by 3-6 times);
3. the tobacco leaves are chemically reacted in the solvent, so the process is not a simple extraction process, but is a little similar to the thermal cracking of the tobacco leaves to produce the aroma;
4. however, unlike thermal cracking, the process is carried out in a specific solvent, and the solid is substantially isolated from air and is in full contact with the solvent; the reaction temperature is also lower, and the aroma characteristics generated by simulating the heating of non-combustible cigarettes are more concerned. Most of the pyrolysis incense collected is aroma components with low volatility, and small molecular substances cannot be effectively captured; therefore, the flavor components are mostly improved, and the head aroma of the smoke is improved weakly.
The preparation method of the tobacco leaf original perfume provided by the invention comprises the following steps:
(1) putting tobacco raw materials into a closed reactor, adding a glycerol-propylene glycol liquid solvent with a certain volume and a certain proportion, heating and stirring for 10-30 min;
wherein, the volume of the solvent takes the solid raw material which is completely submerged as a lower limit, and 3 times of the volume of the lower limit as an upper limit; the ratio of the glycerol to the propylene glycol is determined by the absorption taste of the required perfume and the reaction temperature, the absorption taste of the obtained perfume is greatly different by using solvents with different ratios, and the volume ratio of the glycerol to the propylene glycol in the glycerol-propylene glycol liquid solvent is 2-0: 0-2.
The main reason for this is that the atomization temperature of propylene glycol is low, while the atomization temperature of glycerin is high, which results in different atomization reflux effects under different ratios and reaction temperatures.
(2) And (2) filtering and separating the mixed reactant obtained in the step (1), wherein the obtained liquid is the solvent hot tobacco herb source spice.
The product can not be heated and concentrated subsequently, otherwise, the loss of the small-molecule aroma components collected by atomization reflux is serious. Therefore, the amount of solvent added before the reaction must be strictly controlled.
Adding the obtained tobacco original perfume into a filter tip in the filter tip processing process, wherein the adding amount is determined by the sensory requirements of cigarettes, and each filter tip generally contains 0.2-1 mu L of solution; or can be added into the tobacco shred feed liquid in the cigarette manufacturing process, and the addition amount is 5-20% of the quality of the tobacco shred feed liquid.
The tobacco shred feed liquid refers to a mixed formula solution of spices, sugar materials and other components added in the cigarette production process, and the feed liquid formulas of cigarettes of different brands are different.
The invention has the advantages and effects that:
1. the special smoking flavor of the conventional cigarette which is not burnt after being heated can be generated, and the range of consumer groups is expanded;
2. the smoke irritation can be reduced, the moistening feeling can be improved, and the sensory evaluation score can be improved by 0.5-1 point;
3. when the tobacco original spice is used in the tobacco shred feed liquid, the smoke quantity can be increased, which is particularly important in low-end cigarette products;
4. the method is simple and feasible in treatment, and related equipment is the existing equipment in the market and is low in price.
