The porous plant particles with the scorched aroma prepared by the invention can be used in tobacco to adsorb harmful substances in smoke, and the aroma in the smoke is obviously improved.
Description
Technical Field
The invention relates to the technical field of cigarette material preparation, in particular to a preparation method and application of porous plant particles with burnt fragrance.
Background
The tar reduction and harm reduction are inevitable trends in the development of the tobacco industry, but the smoking taste of cigarettes is reduced, and insufficient aroma gradually becomes a prominent problem in the tobacco development. How to reduce tar and harm and keep the aroma quality and the aroma quantity of smoke is one of the key contents of tobacco research. In the prior art, the method of reducing tar and harm generally adopts a method of adding adsorbing materials such as activated carbon, silica gel micropowder and the like to adsorb harmful substances in smoke, but simultaneously, a large amount of fragrance components are adsorbed, so that the smoking quality of cigarettes is reduced at the same time.
In order to solve the problems, the patent CN110292203A adopts a preparation method of soft carbonization and fermentation to prepare porous particles with plant burnt fragrance, and the particles are added into tobacco, so that the quality of cigarette smoke is improved. The method of patent CN110292203A is a relatively novel and effective method. However, this method has the following problems: 1. the carbonization time is longer, at least two hours are needed, and the plant particles need to be fermented after being carbonized. Low treatment efficiency and difficult adaptation to industrial production. 2. The performance of the carbonized plant particles for adsorbing harmful substances needs to be improved, and particularly the adsorption amount of TSNAs (tobacco-specific nitrosamines). 3. The carbonized plant particles only can keep the burnt fragrance of the plants, and no synergistic effect exists among the fragrances.
The present invention has been made to solve the above problems.
Disclosure of Invention
The invention discloses a preparation method of porous plant particles with tar aroma, and application of the porous plant particles in tar reduction, harm reduction and flavoring of tobacco.
The technical scheme of the invention is as follows:
the invention discloses a preparation method of porous plant particles with burnt fragrance, which comprises the following steps:
(1) processing fresh plant to water content of 5-10 wt%, and pulverizing to obtain plant granule with particle size of 0.5-2.0 mm;
(2) keeping the plant particles obtained in the step (1) for 0.5-2 seconds at 600-800 ℃ under the condition of air isolation;
(3) cooling the particles obtained in the step (2) to room temperature in an air-isolated manner;
(4) and (3) crushing the particles obtained in the step (3) into powder with the particle size of 100-180 meshes, and then bonding the powder into particles with the particle size of 20-60 meshes by using an adhesive, namely the porous plant particles with the scorched aroma.
Preferably, the fresh plant of step (1) is a root, leaf, stem, flower or fruit of a plant.
Preferably, the fresh plant is one or more of ginger, hawthorn, dark plum, liquorice, lotus seed pot, rose petal, honeysuckle, buckwheat, malt or bamboo leaf. .
Preferably, the binder used in step (4) is gelatin or sodium carboxymethyl starch.
The second aspect of the invention discloses the application of the porous plant particles prepared by the preparation method in tar and harm reduction and flavoring of tobacco.
The invention has the beneficial effects that:
1. the preparation method of the porous plant particles with the scorched fragrance uses the kaolin flash firing method as a reference, and water in the plant particles is instantly evaporated at high temperature to leave abundant micropores. The compound can be used in tobacco to adsorb a large amount of harmful substances in smoke, such as tar, CO, TSNAs and the like, and particularly has obvious adsorption effect on NNN [ N-nitrosonornicotine ] and NNK [4- (N-methyl-nitrosamine) -1- (3-pyridyl) -1-butanone ]. NNN and NNK are two components with the strongest carcinogenicity in TSNAs, can induce lung cancer and adenocarcinoma, and are listed as I carcinogens by the International research of cancer (IARC) in 2007.
2. The preparation method of the porous plant particles with scorched aroma is dehydrated instantly at high temperature, but most of the aroma components of the plants are not damaged, so that the scorched aroma of the plants is kept; meanwhile, different synergistic reactions such as Maillard reaction and the like are carried out among part of fragrant substances in different plants, and the obtained porous plant particles not only have the fragrance of the plants, but also obtain special sweet-brown fragrance which does not exist in the plants. This effect cannot be expected by the person skilled in the art. The additive has obvious effect of improving the fragrance of the tobacco when being used in the tobacco.

Fluidized bed granulation is carried out according to the process to prepare particles with the particle size of 40 meshes, namely the porous plant particles with the scorched fragrance.
Example 4: evaluation of smoking
Sensory evaluation of cigarettes: adding the porous plant particles with the scorched flavor prepared in the examples 1, 2 and 3 into a cigarette composite filter stick, and adding 2.0mg of the porous plant particles into each millimeter of a standard cigarette filter stick to respectively obtain 50 cigarettes in the example 1, 50 cigarettes in the example 2 and 50 cigarettes in the example 3; blank 50 cigarettes without added plant particles were used as controls.
All the cigarette cigarettes are placed in a constant-temperature constant-humidity box (the temperature is 22 +/-1 ℃ and the humidity is 60 +/-2%) and balanced for 48 hours, and the cigarette is evaluated by experts with cigarette evaluation qualification according to the standard GB5606.4-2005 part sensory technical requirements of cigarettes, and the results are shown in Table 1. Meanwhile, a net-shaped graph is drawn according to the aroma style characteristics of the cigarettes as shown in the attached figure 1.
TABLE 1 cigarette evaluation results of porous plant particles with burnt flavor
As can be seen from the data in Table 1, the porous plant particles with the scorched aroma prepared by the method are added into the cigarette composite filter stick, and the smoke evaluation scores of the prepared cigarette are higher than those of a control sample; particularly, the aroma and aftertaste are obviously higher than those of a control sample, which shows that the porous plant particles with the burnt aroma have obvious effect of improving the aroma of tobacco, improve the aftertaste, ensure the mellow and harmonious smoke feeling and soft smoke aroma, ensure comfortable and clean oral cavity and improve the aroma quality of cigarettes.
As can be seen from the network diagram of the aroma style characteristics in figure 1, the porous plant particles with the burnt aroma prepared by the invention can highlight the style characteristics of the burnt sweet aroma of the cigarette when being added into the cigarette composite filter stick, and increase the faint scent, flower aroma, fruit aroma, sweet sense aroma and the like which are not possessed by the plant per se. This is probably because under the preparation conditions of the present invention, the synergistic reaction between the fragrant substances in different plants makes the porous plant particles obtain other fragrance while retaining the fragrance of the plants.
Example 5: flue gas detection
The cigarette of example 1, the cigarette of example 2, the cigarette of example 3 and the blank cigarette without plant particles are subjected to conventional smoke detection according to national standard GB 5606.5-2005, and the detection results are shown in Table 2. According to the regulations of GB/T211302007 determination of benzo [ a ] pyrene in total particulate matters of cigarette smoke, YC/T253-, 7 kinds of harmful components in the smoke are detected (wherein NNN and NNK are classified into one group), and the detection results are shown in a table 3.
TABLE 2 cigarette smoke conventional analysis results
TABLE 3 analysis results of eight harmful ingredients in cigarette with porous plant particles having burnt fragrance
As can be seen from Table 2, compared with the blank cigarette, the main stream smoke of the cigarette added with the porous plant particles of the invention has reduced total particulate matter, tar, nicotine and CO, wherein the tar and CO content is obviously reduced, and the moisture content is improved.
As can be seen from table 3, the 7 harmful components in the cigarette to which the porous plant particles of the present invention were added were reduced to different degrees, compared to the blank cigarette. Wherein, the average CO is reduced by 9.37 percent, the average B (a) P is reduced by 25.56 percent, the average NNK is reduced by 7.95 percent, the average NNN is reduced by 14.54 percent, the average crotonaldehyde is reduced by 20.86 percent, the average HCN is reduced by 22.09 percent, the average ammonia ion is reduced by 8.76 percent, and the average phenol is reduced by 25.81 percent; in particular the magnitude of the NNN and NNK reduction is not present in prior art adsorbent materials. The preparation process of the invention can evaporate the water in the plant particles instantly at high temperature to leave abundant micropores which are used in the cigarette filter stick and are suitable for adsorbing a large amount of harmful substances in the smoke; therefore, the content of 7 harmful components in the smoke is obviously reduced.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
