Description

Preparation method of tobacco flavor electronic cigarette tobacco shred functional incense raw material

Technical Field

The invention relates to a preparation method of a functional cigarette raw material of tobacco shreds in electronic cigarette liquid.

Background

Smoking is harmful to health, second-hand smoke is more harmful, secondary pollution and public hazard are formed, so smoke-free tobacco products need to be researched and developed urgently, and novel tobacco products such as electronic cigarettes, heating non-combustible tobacco products, buccal cigarettes and the like become focus of attention in domestic and foreign industries. The combustion process of tobacco has complex reactions such as thermal cracking, Maillard and the like, and different temperatures and atmospheres have great influence on products. Research shows that the types of aroma components released by tobacco are the most when the tobacco is heated to 600 ℃, however, the smoking process of the novel tobacco forms such as electronic cigarettes and heating non-combustion cigarettes cannot reach the heating temperature, so that the tobacco essential oil extracted by the traditional tobacco processing mode cannot bring corresponding satisfaction to consumers when being applied to the novel tobacco, and the novel tobacco forms such as electronic cigarettes and the like cannot bring obstruction to market and replace the traditional cigarette consumption mode.

The applicant Zhejiang tobacco industry Limited liability company applies for Chinese invention patent (CN201510580910.6) and discloses a method for preparing electronic cigarette tobacco juice from tobacco subjected to dry distillation pyrolysis treatment, which comprises the following steps: weighing tobacco, placing the tobacco into a heating furnace, heating to the temperature of 150-.

Chinese invention patent (CN201510246335.6) discloses an electronic cigarette liquid containing dry distillation spice, which is prepared by uniformly mixing 15-50% of dry distillation spice, 30-60% of glycerol and propylene glycol. Wherein, the dry distillation spice is prepared by dry distillation of tobacco under nitrogen atmosphere and at proper temperature. The dry distillation is to dry distill the tobacco at 200-400 ℃ in nitrogen atmosphere, and the distillate flows into a receiving bottle through tap water condensation and is collected, thus obtaining the condensed dry distillation spice.

Chinese invention patent (CN201610086584.8) discloses an electronic cigarette liquid with traditional cigarette fragrance and a preparation method thereof, which comprises the steps of burning and dry distillation of cut tobacco. The combustion of the tobacco shreds is carried out at the temperature of 800-900 ℃ to obtain fully combusted smoke. The dry distillation of the tobacco shreds is carried out at the temperature of 300-400 ℃ to obtain the dry-distilled smoke. The burning smoke and the smoke of the dry distillation react at the temperature of 300 ℃ and 400 ℃, and are dissolved in organic solvents such as ethyl acetate and the like. And (3) carrying out rotary evaporation on the solvent absorption liquid at the temperature of 27-30 ℃ under the pressure of-0.09 MPa to obtain a brown oily extract, namely the tobacco liquid raw material with the aroma characteristics of the traditional flue-cured tobacco type cigarettes.

The Chinese invention patent (CN201410249421.8) discloses a method for extracting Chinese style flue-cured tobacco flavor type tobacco juice for electronic cigarettes, which comprises the following steps: mixing flue-cured tobacco type tobacco leaves, tobacco shreds or tobacco powder, applying tobacco material liquid or sugar-containing substances to the tobacco leaves, the tobacco shreds or the tobacco powder, performing dry distillation on the substances in the step 2) in temperature sections, and collecting fractions. The method specifically comprises the following steps: 1) 70-100 parts of flue-cured tobacco type tobacco leaves, tobacco shreds or tobacco powder, 1-5 parts of tobacco feed liquid or 1-30 parts of substances containing sugar are filled into a dry distillation tank; 2) heating the retort to 60-120 deg.C, and maintaining the temperature for 0.5-2 h; 3) then raising the temperature to 180-240 ℃, and preserving the temperature for 0.5-2 h; 4) and collecting fractions after the reaction is finished.

Disclosure of Invention

In order to overcome the defects of the existing tobacco processing mode applied to novel tobacco and make up the defects of the existing electronic cigarette liquid such as insufficient tobacco fragrance and physiological strength, the invention aims to provide a preparation method of a functional fragrance raw material of electronic cigarette liquid tobacco shreds.

In order to achieve the first object, the invention adopts the following technical scheme:

a preparation method of tobacco functional incense raw materials of tobacco juice of tobacco flavor electronic cigarette comprises the following steps:

1) weighing tobacco shreds, adding the tobacco shreds into a reaction kettle, pressurizing for 1.0-2.0 MPa under an inert condition, heating to 90-150 ℃, and electrically stirring for 0.5-5 hours; the solvent is one or a mixture of two or three of ethanol, glycerol and propylene glycol;

2) and after the reaction is finished, cooling by circulating water, adding a solvent, immersing overnight, extracting, and filtering to obtain a filtrate.

As a further improvement, the conditions of high pressure and low temperature are 1.2-1.80 MPa, the temperature is 100-120 ℃, and the reaction time is 1-3 h.

As a further improvement, the cut tobacco is one or a mixture of more of flue-cured tobacco cut tobacco, aromatic tobacco cut tobacco, sun-cured yellow tobacco cut tobacco, burley tobacco cut tobacco, middle-flavor cut tobacco, strong-flavor cut tobacco and fen-flavor cut tobacco.

In the prior art, the dry distillation extract has high temperature, is generally extracted at 350 ℃, and is too heavy in burnt flavor when applied to electronic cigarettes, so that the dry distillation extract cannot be used for electronic cigarette liquid main body fragrance with the herbal fragrance type. The supercritical extract is generally extracted at the temperature of below 50 ℃, and the cigarette smoke generated by the extract is heavy and has a slight residual feeling. The high-pressure low-temperature reaction can obtain 100-plus 200-DEG C reaction products, which are expressed by the fact that the tobacco fragrance is enough, the burnt fragrance is moderate, the gas of the generated smoke is light, the compatibility is good, the requirement of the main body fragrance of the electronic cigarette liquid can be met, in addition, the extraction method uses propylene glycol or glycerin as a solvent, the stability is good, the refrigeration is not needed, the reaction condition is simple, the products in batches have no obvious difference, and the industrial production can be realized.

Due to the adoption of the technical scheme, the invention has the following advantages:

1. the functional fragrant raw material provided by the invention can endow the electronic cigarette smoke with obvious tobacco flavor characteristics, has rich fragrance, comfortable and clean mouthfeel and moderate strength, and greatly improves the sensory quality, so that the market acceptance of the tobacco-flavor electronic cigarette is favorably improved.

2. The functional incense raw material provided by the invention has stable property, strong pertinence, convenient use and simple production process.
