Problems solved by technology

The normal pressure method has the following disadvantages in the production of tobacco flavors: 1. Long reaction time, low production efficiency, and high energy consumption; 2. Low effective content of the product, large dosage, and high cost; 3. High cracking temperature and large volatilization loss of aroma components
[0004] At present, how to change the technology of terpenoid compound atmospheric pressure production of tobacco flavors at home and abroad, invent a short reaction time, high production efficiency, low energy consumption; low cracking temperature, low volatilization loss of aroma components; The new method of terpenoids tobacco flavors with few and low cost has not been reported yet; no new invention of producing terpenoids tobacco flavors without normal pressure method has been found in domestic and foreign patent documents
[0005] At the Flavor Conference held in Hamburg, Germany in February 1982, V.HEEMANN made a report on "Cembranoids of Tobacco, Their Flavor Assessment and Degradation Products", which only evaluated the possible effects of cembranes in the tobacco aging process. Degradation products and their sensory evaluation results did not propose a new method for the production of terpenoid tobacco flavors

Embodiment 1

[0026] The tobacco terpene complex agent is prepared according to the following proportions: 0.6-0.7 parts of cembradane, 0.3-0.4 part of neophytadiene, and 0.01-0.03 parts of potassium permanganate are uniformly mixed to prepare the tobacco terpene compound agent.

[0027] Accurately weigh 4.00 g of the tobacco terpene compound, dissolve it in 100 ml of glycerol triacetate, and add it into the autoclave after ultrasonically dissolving evenly. The oxygen pressure in the autoclave was maintained at 15,000 hPa, the stirring program was started, and the stirring rate was controlled at 500 rpm. Simultaneously energize and heat up at a rate of 8°C / min to 80°C; after maintaining the reaction temperature for 6 hours, pass in condensed water to rapidly condense. After the temperature in the kettle drops to normal temperature and the pressure drops to normal pressure, the reactant is taken out to obtain the product of the present invention.

[0028] The inventive product prepared by t...

Embodiment 2

[0030] Prepare the tobacco terpene compound according to the method of Example 1. Accurately weigh 8.00 g of the tobacco terpene complex agent and dissolve it in 200 ml of ethanol solution, ultrasonically dissolve it until uniform, and then add it into the autoclave. The air pressure of the autoclave is maintained at 30,000 hPa, and the reaction temperature is 95°C. While stirring at 600 rpm. After reacting for 5 hours, feed condensed water to carry out rapid condensation. After the temperature and pressure in the kettle drop to normal temperature, the reactant is taken out to obtain the product of the present invention.

[0031] The inventive product prepared by the reaction was added to 2006 Guizhou B3F shredded tobacco at a ratio of 2 / 10,000 for evaluation and smoking. The results showed that the product could effectively improve the aftertaste of the smoke, clean the mouth, and at the same time play a very good role. Perfuming effect.

Embodiment 3

[0033] Prepare the tobacco terpene compound according to the method of Example 1. Accurately weigh 7.50 grams of tobacco terpene complex agent and dissolve it in 200ml propylene glycol, ultrasonically dissolve until uniform and add it to the autoclave. The air pressure of the autoclave is maintained at 25,000 hPa while stirring at 600 rpm; The temperature is 100°C, and after 3.5 hours of reaction, condensed water is passed in for rapid condensation. After the temperature in the kettle drops to normal temperature and the pressure drops to normal pressure, the reactant is taken out to obtain the product of the present invention.

[0034] The substance prepared by the reaction was added to 2006 Guizhou B3F shredded tobacco at a ratio of 2 / 10,000 for smoking. The results showed that the product could effectively cover up the woodiness and green mist in the tobacco, reduce the vigor and significantly improve the mist. , to give tobacco products a good sweet aroma.

Abstract

The invention relates to a method for preparing tobacco spices by using tobacco terpenoids as raw materials through pressurized oxidation. At present, both at home and abroad, the atmospheric pressure method is used to prepare terpenoid tobacco flavors, which has the disadvantages of long reaction time, low product effective content, high reaction temperature, and large volatilization loss. The method of the present invention comprises the following steps: adding terpenoids into a solvent for ultrasonic dissolution, putting them into a reaction kettle, feeding pressurized air or oxygen into the reaction kettle, stirring, and raising the temperature to 80-130°C; reacting for 3-6 hours; After the condensed water is cooled to normal temperature and the pressure drops to normal pressure, the inventive product is taken out. The invention has the advantages of short reaction time, low reaction temperature and high effective product content.

Description

technical field [0001] The invention relates to a method for preparing tobacco flavoring, in particular to a method for preparing tobacco flavoring by pressurizing and oxidizing tobacco terpenoids. Background technique [0002] The aroma, aftertaste, miscellaneous smell, irritation and coordination of smoke are important quality characteristics of tobacco products. The current control methods for these quality indicators at home and abroad are mainly controlled by adding some characteristic compounds. These characteristic compounds refer to the substances with relatively low content in tobacco, but have a strong influence on the taste, pleasure and satisfaction of cigarettes; at the same time, these compounds are also important aromatizing substances in tobacco, which have a strong impact on cigarette smoking. The contribution of temperament is indispensable. The main trace characteristic compounds in tobacco mainly include ionone, oxo-β-damascenone, macrostigmatrienone, o...
