Embodiment 1

[0029] Weigh 500 grams of oolong 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 obtain 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 1.2 g of extract.

Embodiment 2

[0031] Weigh 1,000 grams of oolong tea with an electronic balance, put it into a Erlenmeyer flask, add 10,000ml of petroleum ether with a boiling point of 60-90°C, soak it at 30°C for 20 hours, use a Bush funnel for solid-liquid separation, and collect the clear 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 6.75 g of extract.

Embodiment 3

[0033] Weigh 1,000 grams of oolong tea with an electronic balance, put it into a Erlenmeyer flask, add 15,000ml of petroleum ether with a boiling point of 30-60°C, soak it at 15°C for 10 hours, use a Bush funnel to separate the solid from the liquid, and collect the clear liquid. The vacuum degree is 0.01MPa, the distillation temperature is 25°C and the distillation is concentrated for 1.5h, and the solvent is removed to obtain 6.8g of extract.

Abstract

The invention discloses oolong extractum extracted through petroleum ether and a preparation method and an application thereof. The product is produced through uniform mixing of oolong and petroleum ether, extraction, liquid-solid separation, distillation and concentration. The oolong extractum extracted through petroleum ether is diluted to be in the concentration of 1-10 percent through 95 percent of ethyl alcohol, and then added into tobacco shreds according to 0.01-0.1 percent of the weight of the tobacco shreds to provide the tobacco with special fragrance. Simultaneously, free amino acid in oolong can well react with Maillard during the alcoholization and burning process of the tobacco to generate fragrant substances, and can also neutralize the alkaline matters in the tobacco, so as to reduce excitation, enrich the tobacco fragrance, reduce excitation and impurity smell, and improve the taste and residual taste. The oolong extractum, the preparation method and the application have the advantages that the technology is simple, the operation is simple, the prior manufacturing technique is not required to be changed, the product can not cause solvent contamination, and has good application prospect.

Description

technical field [0001] The invention belongs to the technical field of tobacco additive preparation, and in particular relates to an oolong 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] Oolong tea is a semi-fermented tea. After green tea is fermented, the catechins in the tea will combine with each other as the fermentation temperature rises, making the color of the tea darker and the astringency of the tea reduced, thus forming the unique taste of oolong tea. Oolong tea is rich in catechins and polyphenols, which have the effects of tooth health, moth prevention, anti-oxidation, promotion of SOD production, improvement of skin allergies, fat elimination, anti-tumor and anti-aging effects. [0003] The aroma of oolong tea is mainly derived from the hydrolysis of terpenes and aromatic alcohol glycosides, the oxidative cracking ...
