Embodiment 1

[0030] Weigh 500 grams of black 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 of 0.05 MPa and a distillation temperature of 28° C., and the solvent was removed to obtain 1.64 g of extract.

Embodiment 2

[0032] Weigh 1000 grams of dark 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 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 under the conditions of vacuum degree of 0.1 MPa and distillation temperature of 30° C., and remove the solvent to obtain 9.23 g of extract.

Embodiment 3

[0034] Weigh 1000 grams of black 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 9.25 g of extract.

Abstract

The invention discloses a black-tea alcohol extract extracted from petroleum ether as well as a preparation method and applications thereof. The black-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 black-tea and the petroleum ether. The alcohol of 95 percent used for the black-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 black-tea can better participate 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 black-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 black tea extract extracted with 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] Black tea is made by fermenting Aspergillus niger and has a black appearance. During the fermentation process, it will produce a Pu Nuoer component, which can prevent fat accumulation. Consistently drinking black tea every day will have a significant effect on inhibiting the increase of abdominal fat. The aroma of dark tea is generally aged. According to the analysis of the aroma concentrate of black tea, dark tea contains methoxybenzene and its derivatives that have not been found in other teas. These substances make the aroma of dark tea mellow , It is also one of the identification basis for the aroma and smell characteristics of dark tea. There are...
