Embodiment 1

[0029] Pu'er raw tealeaves are pulverized through 80 mesh sieves, and the pulverized tealeaves and extractant are transferred to a simultaneous distillation-extraction device (SDE). The mass volume ratio (g / mL) is 1:10, soak for 20min. The process conditions of the simultaneous distillation-extraction device are as follows: extraction at a temperature of 70° C. for 1.5 h. Add an appropriate amount of anhydrous CaCl to the distillate 2 Stand in the refrigerator for 12 hours, and filter to obtain the essential oil of Pu'er raw tea.

[0030] The obtained Pu'er raw tea essential oil is a dark green viscous liquid, and the volatile aromas in the essential oil present a characteristic aroma of clear and sweet, mellow, sweet and fresh tea leaves. The extracted Pu'er raw tea essential oil is diluted with a mixture of 95% ethanol and propylene glycol (v / v=2-3:1) to a concentration of 0.5%. Proportioning the diluted Pu'er raw tea essential oil and triacetin to a mixed solution conta...

Embodiment 2

[0032] Puer raw tea leaves were crushed through an 80-mesh sieve, and the crushed tea leaves and extractant were transferred to a simultaneous distillation-extraction device. The mass-volume ratio (g / mL) of the tea leaves to the extractant was 1:15, and soaked for 20 minutes. The extraction device extracts at a temperature of 70°C for 2h. Add an appropriate amount of anhydrous Na to the distillate 2 SO 4 Stand in the refrigerator for 12 hours, and filter to obtain the essential oil of Pu'er raw tea.

[0033] The extracted raw Pu'er tea essential oil was diluted with a mixture of 95% ethanol and propylene glycol (v / v=2-3:1) to a concentration of 1%.

[0034] Then the diluted Pu'er raw tea essential oil is filled in bead capsules, and the size of the capsules is 3.5 mm. The capsule containing raw Pu'er tea essential oil is placed in a cavity between two sections of tow rods in the filter rod, and the capsule is broken by hand when smoking a cigarette, and the raw Pu'er tea esse...

Embodiment 3

[0036] Puer raw tea leaves were crushed through an 80-mesh sieve, and the crushed tea leaves and extractant were transferred to a simultaneous distillation-extraction device. The mass-volume ratio (g / mL) of the tea leaves to the extractant was 1:15, and soaked for 20 minutes. The extraction device extracts at a temperature of 70°C for 2h. Add an appropriate amount of anhydrous Na to the distillate 2 SO 4 Stand in the refrigerator for 12 hours, and filter to obtain the essential oil of Pu'er raw tea.

[0037] The extracted Pu'er raw tea essential oil was diluted with a mixture of 95% ethanol and propylene glycol (v / v=2-3:1) to a concentration of 1%.

[0038] Then, the diluted Pu-erh raw tea essential oil is used as a core material and wrapped into microcapsules, and the wall material of the microcapsules is a mixture of gelatin: gum arabic: maltodextrin in a weight ratio of 1:1:1. The diameter of the microcapsule is 0.3-1.0 mm. The weight ratio of the raw Pu'er tea essentia...

Abstract

The invention discloses a method for extracting Pu-Er raw tea essential oil. The method comprises the steps that smashed Pu-Er raw tea is extracted through extraction agents, meanwhile, the extraction agents are heated and distilled to obtain distillate and distilling residual liquid, and the distillate is the oily Pu-Er raw tea essential oil. The invention further discloses the purpose of the Pu-Er raw tea essential oil in a cigarette filter stick. The purpose comprises one of the three purposes that the diluted Pu-Er raw tea essential oil is dissolved in glycerol triacetate to be added to a filter stick strand as plasticizer; or, a bead capsule is filled with the diluted Pu-Er raw tea essential oil to be placed in a cavity formed by two strand sticks to manufacture a composite nozzle stick; or, the diluted Pu-Er raw tea essential oil is adopted as core materials to manufacture microcapsule to be dispersed in acetic acid cellosilk, and the composite filter stick is formed. The functional components in the diluted Pu-Er raw tea essential oil are beneficial to improving the sense quality of a cigarette in aroma enhancement, moisture preservation, secretion promotion and sweat after taste.

Description

technical field [0001] The invention belongs to the technical field of tobacco additive preparation, and in particular relates to a method for extracting raw Pu'er tea essential oil and its application in cigarette filter sticks. Background technique [0002] Chinese-style cigarettes generally have problems such as low mainstream smoke moisture, obvious irritation and dryness, and oral phlegm. The combination of these unfavorable factors affects the smoking comfort and taste of cigarettes. In order to overcome these common problems, we are objectively required to develop more suitable smoking materials, so as to reduce the dryness of the smoke and improve the mouth fluid and comfort during the smoking process. Contents of the invention [0003] The object of the present invention is to propose a kind of application of raw Pu'er tea essential oil in cigarette filter sticks in view of the deficiencies in the prior art. The present invention makes full use of the sensory cha...
