Embodiment 1

[0030] Weigh 500 grams of dry green tea with an electronic balance, put it into a flask, add 2500ml of medical grade petroleum ether with a boiling point of 30-60°C, soak for 10 hours at 20°C, separate the solid and liquid with a Bush funnel, collect the clear liquid, and get The liquid was distilled and concentrated for 2.0 h at a vacuum degree of 0.05 MPa and a distillation temperature of 28° C., and the solvent was removed to obtain 0.4 g of extract.

Embodiment 2

[0032] Weigh 1,000 grams of dry green tea with an electronic balance, put it into an Erlenmeyer flask, add 10,000ml of petroleum ether with a boiling point of 60-90°C, soak for 20 hours at 30°C, separate the solid and liquid with a Bush funnel, collect the clear liquid, and obtain the liquid Distill and concentrate for 1.0 h at a vacuum of 0.1 MPa and a distillation temperature of 30° C., and remove the solvent to obtain 2.25 g of extract.

Embodiment 3

[0034] Weigh 1,000 grams of dry green tea with an electronic balance, put it into an Erlenmeyer flask, add 15,000ml of petroleum ether with a boiling point of 30-60°C, soak at 15°C for 10 hours, separate the solid and liquid with a Bush funnel, collect the clear liquid, and obtain the liquid Distill and concentrate for 1.5 h under the condition of vacuum degree of 0.01 MPa and distillation temperature of 25° C., and remove the solvent to obtain 2.31 g of extract.

Abstract

The invention discloses a green-tea extract extracted by petroleum ether as well as a preparation method and applications thereof. The green-tea is uniformly mixed with the petroleum ether and then a product is manufactured after the processes of extraction, solid-liquid separation, distilling and condensation are carried out on the mixture of the green-tea and the petroleum ether. The green-tea extract extracted by petroleum ether is diluted to a concentration of 1 to 10 percent by 95% ethanol, 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 green-tea extract extracted by petroleum ether 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 extract extracted from petroleum ether. At the same time, the invention also relates to the preparation method of the extract 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 t...
