Embodiment 1

[0031] Weigh 500 grams of dry white 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 0.3 g of extract.

Embodiment 2

[0033] Weigh 1000 grams of dry white tea with an electronic balance, put it into an Erlenmeyer flask, add 10000ml of petroleum ether with a boiling point of 60-90°C, soak at 30°C for 20 hours, 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 2.15 g of extract.

Embodiment 3

[0035] Weigh 1000 grams of dry white tea with an electronic balance, put it into an Erlenmeyer flask, add 15000ml 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 conditions of vacuum degree of 0.01 MPa and distillation temperature of 25° C., and remove the solvent to obtain 2.20 g of extract.

Abstract

The invention discloses a white-tea alcohol extract extracted from petroleum ether as well as a preparation method and applications thereof. The white-tea is uniformly mixed with the petroleum ether and then a product is manufactured after the processes of extraction, solid-liquid separation, distilling and condensing are carried out on the mixture of the white-tea and the petroleum ether. The alcohol of 95 percent used for the white-tea alcohol extract extracted from petroleum ether is diluted to a concentration of 1 to 10 percent; 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 white-tea can better particiate in a maillard 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 white-tea alcohol 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 white 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] Interferon is the "chemical defense line" for the human body to resist infection, and drinking tea can increase the secretion of interferon by human blood immune cells by 5 times. This is because there is a substance called "theanine" in tea, which is decomposed into ethylamine in the human liver, and ethylamine can mobilize the cells called "Gamma-delta T cells". Human blood immune cells promote the secretion of interferon, which can improve the body's ability to resist external aggression. The content of free amino acids in ordinary tea is only 2% to 4%, of which theanine accounts for 50% to 60% of the total amount of amino acids. [0003] White tea i...
