Embodiment 1

[0026] Weigh 500 grams of Pu’er raw tea with an electronic balance, put it into an Erlenmeyer flask, add 2500ml of edible alcohol with a concentration of 95%, stir evenly at 40°C, heat and soak for 100 hours, separate the solid and liquid with a Bush funnel, collect the clear liquid, and obtain The liquid was first distilled at 80°C under normal pressure for 0.5h, then concentrated by distillation at a vacuum of 0.05MPa and a distillation temperature of 45°C for 2.0h to obtain 27g of extract.

Embodiment 2

[0028] Weigh 100 grams of raw Pu-erh tea with an electronic balance, put it into an Erlenmeyer flask, add 1000ml of ethanol (concentration 75%), uniformly stir, heat and soak at 80°C for 1 hour, use a Bush funnel to separate the solid from the liquid, and collect the clear liquid to obtain The liquid was first distilled at 80°C under normal pressure for 0.5h, then concentrated by distillation at a vacuum of 0.1MPa and a distillation temperature of 60°C for 1.0h to obtain 7.8g of extract.

Embodiment 3

[0030] Weigh 100 grams of Pu'er raw tea with an electronic balance, put it into an Erlenmeyer flask, add 1500ml of ethanol (concentration 50%), uniformly stir, heat and soak for 300 hours at 20°C, use a Bush funnel to separate the solid from the liquid, and collect the clear liquid to obtain The liquid was first distilled at 80°C for 0.5h under normal pressure, then concentrated by distillation for 1.5h at a vacuum of 0.01MPa and a distillation temperature of 15°C to obtain 7.9g of extract.

Abstract

The invention discloses a green puerh tea ethanol extract, a preparation method thereof and the application. Green puerh tea is extracted by using ethanol, and the extract liquid is carried out the clarification, the filtration, the distillation and the concentration to prepare the product. The green puerh tea ethanol 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 preparation of tobacco additives, and in particular relates to an alcoholic extract of raw Pu'er tea. 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, it is divided into...
