Problems solved by technology

[0003] In view of the above problems, the inventor applied other esters which are suitable for use in cigarettes to cigarettes according to the usual thinking of those skilled in the art, but found that the above-mentioned aromas still have fast release, uneven release, and intolerance. The problem of baking and suction drying

Embodiment 1

[0026] Add 0.2 mol of dihydrocoumarin into a three-necked flask, and continue to add 0.3 mol of absolute ethanol, heat and stir in an oil bath to dissolve, then add 0.6 mol of 10 mol / L NaOH solution, react at 80°C, and detect by chromatography , stop heating after conversion of raw materials and cool to room temperature to obtain saponified liquid.

[0027] Under the condition of reduced pressure of 76mmHg, evaporate ethanol and a part of water to the saponified liquid, and add 30mL of saturated salt solution or water-absorbing agent sodium sulfate to it to obtain the concentrated saponified liquid;

[0028] Measure 300mL of 2.0mol / L HCl solution, add 70.0g of NaCl solid particles to it, stir quickly to dissolve it, add it to the concentrated saponification solution at room temperature for acidification, precipitate the product, and refrigerate overnight at 0°C Let it age. Finally, the product was obtained by suction filtration under reduced pressure.

[0029] The results of...

Embodiment 2

[0031] Flavoring experiment 1

[0032] Take the 3-(2-hydroxyphenyl)propionic acid prepared in Example 1 and dilute it with Daqu wine at 52° C. to a solution with a concentration of 2.0 g / L. Take 5mL of the above solution, add flavor by spraying, so that the above solution is evenly sprayed on 1000g cut tobacco, equilibrate at 22°C and relative humidity of 60% for 48h, bake, take out and make cigarettes, smoke for evaluation, and compare with the control sample Comparison (addition of dihydrocoumarin) for evaluation.

Embodiment 3

[0034] Flavoring experiment 2

[0035] Take the 3-(2-hydroxyphenyl)propionic acid prepared in Example 1 and dilute it with Daqu wine at 52° C. to a solution with a concentration of 2.0 g / L. Take 5mL of the above-mentioned solution, add flavor by spraying, spray the above-mentioned solution evenly on 1000g of thin slices, equilibrate at 22°C and relative humidity of 60% for 48h, bake, take out and make cigarettes, and smoke them for evaluation, compare with the control sample Comparison (addition of dihydrocoumarin) for evaluation.

Abstract

The invention relates to the application of 3-(2-hydroxyphenyl) propionic acid in cigarettes. The 3-(2-hydroxyphenyl) propionic acid is applied to the cigarettes as an aroma enhancer, and by the weight of tobacco shreds or slices in the cigarettes, the addition amount of the 3-(2-hydroxyphenyl) propionic acid is 1-100 ppm. By adding the aroma enhancer, the cigarettes with a proper aroma release speed, good aroma release uniformity, good moisture retention and good bake resistance can be obtained, and the smoking quality of the cigarettes is improved.

Description

technical field [0001] The invention belongs to the technical field of cigarette flavoring, and in particular relates to the application of 3-(2-hydroxyphenyl) propionic acid in cigarettes. Background technique [0002] The flavor enhancers that can be added in existing cigarettes include esters such as dihydroactinolactone, octahydrocoumarin, and dihydrocoumarin, which have unique aroma characteristics. In the prior art, they are used in It is widely used as tobacco spice in cigarettes, especially in flue-cured tobacco. However, due to the overbearing aroma of octahydrocoumarin and dihydrocoumarin, and the volatile nature of dihydroactinolactone, octahydrocoumarin, and dihydrocoumarin, etc., the aroma release speed is fast, making it difficult to smoke. Uniform, and there is the problem of suction drying, which has been unfavorable for its effective use in tobacco as a flavoring agent. Those skilled in the art urgently need to find a flavor enhancer, hoping to effectively...
