Embodiment 1

[0028] Weigh 500 grams of yellow 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 10h 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 0.6 g of extract.

Embodiment 2

[0030] Weigh 1000 grams of yellow 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 at a vacuum of 0.1 MPa and a distillation temperature of 30° C., and remove the solvent to obtain 2.45 g of extract.

Embodiment 3

[0032] Weigh 1000 grams of yellow 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 condition of vacuum degree of 0.01 MPa and distillation temperature of 25° C., and remove the solvent to obtain 2.50 g of extract.

Abstract

The invention discloses a yellow-tea extract extracted by petroleum ether as well as a preparation method and applications thereof. The yellow-tea is uniformly mixed with the petroleum ether and a product is manufactured after the processes of extraction, solid-liquid separation, distilling and concentration are carried out on the mixture of the yellow-tea and the petroleum ether. The yellow-tea extract extracted by petroleum ether is diluted to a concentration of 1 to 10 percent by 95% ethanol, and 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 yellow-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 techniqueis not needed to be changed; the product does not have a solvent pollution; therefore, the yellow-tea 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 yellow 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] People found from fried green tea that the leaf color turned yellow due to insufficient or untimely drying after finishing and kneading, so a new category-yellow tea was produced. Yellow tea is a kind of fermented tea. The production of yellow tea is similar to that of green tea, but the difference is that there is an additional boring process. This boring process is the main feature of yellow tea production method, and also the basic difference between it and green tea. The color of yellow tea soup is apricot or orange, and its cold nature has the effect of detoxifying, reducing fever and reducing fire. The basic production of yellow tea has to go thr...
