Embodiment 1

[0029] Weigh 500 grams of Pu’er raw 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 at 20°C for 10 hours, separate the solid and liquid with a Bush funnel, and collect the clear liquid. The obtained 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 2.4 g of extract.

Embodiment 2

[0031] Weigh 1,000 grams of Pu’er raw 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 at 30°C for 20 hours, separate the solid and liquid with a Bush funnel, and collect the clear liquid to obtain The liquid was distilled and concentrated for 1.0 h at a vacuum of 0.1 MPa and a distillation temperature of 30° C., and the solvent was removed to obtain 13.50 g of extract.

Embodiment 3

[0033] Weigh 1,000 grams of Pu’er raw 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, and collect the clear liquid to obtain The liquid was distilled and concentrated for 1.5 h at a vacuum of 0.01 MPa and a distillation temperature of 25° C., and the solvent was removed to obtain 13.60 g of extract.

Abstract

The invention discloses a petroleum ether extracted green puerh tea extract, a preparation method thereof and the application. Green puerh tea and petroleum ether are evenly mixed, and the product is prepared by extraction, solid-liquid separation, distillation and concentration. The petroleum ether extracted green puerh tea extract is diluted to the concentration of 1 to 10 percent by using 95 percent of ethanol and then added in the cut tobacco according to 0.01 to 0.1 percent of the weight of the cut tobacco, thereby giving the special aroma to the tobacco. Free amino acids in the green puerh tea can well participate in the Maillard reaction during the tobacco alcoholization and the combustion processes to produce the fragrant substances and neutralize the alkaline substances in the tobacco to reduce the stimulus, enrich the smoke aroma, reduce the stimulus and the miscellaneous gas and improve the finish after the taste. The process of the invention is simple, the operation is simple, the existing production process does not need to be changed, and the product does not have the solvent pollution, thereby having great application prospect.

Description

technical field [0001] The invention belongs to the technical field of tobacco additive preparation, and in particular relates to an extract of Pu'er raw tea 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] Pu'er tea is a famous historical tea in Yunnan. It generally refers to sun-dried green tea made from Yunnan big-leaf tea that meets the environmental conditions of the Pu'er tea production area, as well as various specifications made from green tea after piled up and pressed. of pressed and loose teas. Pu'er tea has its own unique processing technology, which generally needs to go through several processes such as greening, rolling, drying, and stacking. Freshly picked tea leaves become Pu-erh Maocha after being greened, twisted and dried. At this time, the Pu-erh tea has a strong flavor, sharp and unreasonable. After raw tea is made, i...
