Problems solved by technology

[0003] At present, most tobacco absolutes are prepared by traditional methods such as steam distillation and organic solvent extraction. However, the production of tobacco absolutes by such processes not only has a low yield and cumbersome steps, but also makes the extraction of the main aroma components in tobacco difficult. Sex is not high

Embodiment 1

[0011] Example 1: Take 70g of oriental tobacco crude extract and mix it evenly with glass beads, put it into the extraction kettle, and carry out supercritical extraction. The extraction temperature is 40 ℃, the pressure is 25MPa, and the flow rate is about 5 L / min. Supercritical CO2 Add 8% (volume ratio) entrainer at the same time; after reaching the extraction conditions, the extraction time is 3 h, and the product is obtained.

Embodiment 2

[0012] Example 2: Take 70g of oriental tobacco crude extract and mix it evenly with Raschig ring, put it into the extraction kettle, and carry out supercritical extraction. The extraction temperature is 45°C and the pressure is 25MPa. Add 8% (volume ratio) entrainer while injecting CO2; after reaching the extraction conditions, the extraction time is 5h, and the product is obtained.

Embodiment 3

[0013] Example 3: Take 70g of oriental tobacco crude extract and mix it evenly with the saddle ring and put it into the extraction kettle for supercritical extraction. The extraction temperature is 40°C and the pressure is 25MPa. Supercritical CO2 with a flow rate of about 2L / min is injected. Add 8% (volume ratio) entrainer at the same time; after reaching the extraction conditions, the extraction time is 3h, and the product is obtained.

Abstract

The invention relates to a preparation method of a tobacco absolute. The preparation method comprises the following steps: uniformly mixing 70g of crude extract of aromatic tobacco with chemical fillers and stirring; extracting the mixture in an extraction kettle at 40 to 45 DEG C under 25 to 30MPa; introducing overcritical CO2 at flow rate being about 2 to 5L / min and adding 4 to 8% of entrainer (volume ratio) at the same time; and extracting for 3 to 5 hours after the extracting condition is met, thus obtaining the tobacco absolute, wherein the chemical fillers can be the ceramic fillers such as glass bead, Raschig ring or Intalox ring. The preparation method can be used for preparing the tobacco absolute rich in aromatic components simply, conveniently and easily.

Description

Technical field: [0001] The invention relates to the field of preparation of absolute, in particular to the field of preparation of tobacco absolute. technical background: [0002] Tobacco absolute is a class of aromatizing compounds extracted from tobacco plants (flue-cured tobacco, burley tobacco, oriental tobacco) and has the characteristic aroma of tobacco. It can enhance the characteristic aroma of tobacco, make the smoke plump and improve the aroma of smoke It can reduce irritation, remove miscellaneous gas, and improve the grade of cigarettes. It is considered to be the most ideal additive for tobacco products. [0003] At present, most tobacco absolutes are prepared by traditional methods such as steam distillation and organic solvent extraction. However, the production of tobacco absolutes by such processes not only has a low yield and cumbersome steps, but also makes the extraction of the main aroma components in tobacco difficult. Sex is not high. Invent...
