Embodiment 1

[0026] Use an electronic balance to weigh 500 grams of dry green tea, put it into a Erlenmeyer flask, let water vapor at 100°C flow through one port to the bottom, and connect the other outlet to the condenser, which is connected to the oil-water separator. After 2 hours of distillation, the oil-water separator has no oil drops Appear, oil-water separation obtains 0.11 gram of green tea essential oils.

Embodiment 2

[0028] Weigh 1000 grams of dry green tea with an electronic balance, put it into a Erlenmeyer flask, let water vapor at 120°C flow through one port to the bottom, and connect the other outlet to the condenser tube, which is connected to the oil-water separator. After distillation for 10 hours, the oil-water separator is free of oil Beads appeared, and 0.21 g of green tea essential oil was obtained after oil-water separation.

Embodiment 3～4

[0030] Repeat embodiment 1 or 2, have following difference: described green tea is bright green tea.

Abstract

The invention discloses a green-tea essential oil as well as a preparation method and applications thereof. The green-tea is distilled for 2 to 10h by water vapor; then a product is manufactured after the processes of condensation and oil-water separation are carried out on the green tea. The green-tea essential oil is distilled to a concentration of 0.1 to 0.5 percent by 95% ethanol and then is added into the cigarette filaments according to 0.01 to 0.1 percent of the weight of the cigarette filaments for endowing special fragrance for the tobacco Simultaneously, free amino acids in the green-tea can better participate in a Mailard reaction during the alcoholizing and burning process of the tobacco to generate a flavor matter and can neutralize the alkaline matters in the tobacco, thereby reducing stimulation, enriching the fragrance of the cigarette, lessening the stimulation and unpurified gases as well as improving the taste and aftertaste. The technique of the invention is simple; the operation is simple and convenient; besides, the existing production technique is not needed to be changed; the product does not have a solvent pollution; therefore, the yellow-tea extract has an excellent application prospect.

Description

technical field [0001] The invention belongs to the technical field of preparation of tobacco additives, in particular to a green tea essential oil. At the same time, the invention also relates to a preparation method of the green tea essential oil and its application in cigarettes. Background technique [0002] Green tea contains a lot of catechins and antioxidant vitamins (including: β-carotene, vitamin E and vitamin C, etc.), which have the effect of preventing cancer and delaying aging. Moreover, the antioxidant effect of green tea is 20 times that of vitamin E, which can reduce the generation of active oxygen, effectively scavenge free radicals, and is quite helpful in preventing senile diseases. Studies have proved that green tea can also inhibit the transformation of food preservatives-nitrite into carcinogens in the human body, inhibit the action of microsomal enzyme system and carcinogens, and prevent the carcinogenic process, which is of great benefit to the preve...
