Patent CN201710984544.X discloses a special orange blossom flavor essence for heat-not-burn cigarettes and its preparation method. The spices in tobacco raw materials are easily lost due to mechanical extrusion, resulting in low content of flavor substances; patent CN105595415A discloses a method of using lychee nectar to prepare honey-flavored cigarette incense thread, soaking short plant fibers in lychee nectar spice liquid, Air-dried to get honey-flavored cigarette incense
Fragrance thread made by soaking method, some flavors and fragrances will be released early during the filter forming process, resulting in loss
During the storage and transportation of cigarettes, due to the lack of effective shielding, some flavors and fragrances will escape, resulting in unsatisfactory smoking.

Embodiment 1

[0031] A flower-flavored fragrance-containing microcapsule used in heat-not-burn tobacco provided in Example 1 is prepared as follows: 45 parts of gelatin, 25 parts of carboxymethyl chitosan, and 30 parts of modified starch are dissolved at 55°C In hot water, the solution concentration is 1%, add 130 parts of the above-mentioned floral essence, emulsify for 15 minutes under continuous stirring at 650 rpm, keep the solution temperature at 35 °C, add 10% citric acid solution to slowly adjust the pH to 3.8, and stir at a constant temperature at 450 rpm for 20 minutes ; Lower the temperature of the solution to 10°C in an ice-water bath, add 1.35 parts of glutaraldehyde and 0.9 parts of glyoxal, and adjust the pH to 7.0 with 5% NaOH solution; heat the system in a water bath to 40°C, solidify for 1 hour, stop stirring, and let stand. Suction filtration, wash off the residual curing agent on the surface of the microcapsules, and dry at room temperature to obtain a powdery sample, whic...

Abstract

The invention provides a preparation method and an application of fragrant tows for novel heat-not-burning tobaccos. The preparation method of the fragrant tows includes the steps: uniformly mixing fragrance-containing microcapsules and cellulose diacetate; adding mixture into solvents to prepare mixed solution with 15-25% of mixture; performing standing and defoaming; coagulating the mixture in coagulating bath formed by the solvents and water by a wet and dry spinning machine to obtain the tow. A preparation method of the fragrant microcapsules includes the steps: mixing gelatin and polysaccharides, and dissolving mixture in water to prepare wall material solution with the mixture concentration of 0.5%-2.0%; adding fragrant essence to continuously stir and emulsify mixture, adding curingagents to heat mixture to reach the temperature of 35+ / -5 DEG C, and curing the mixture for 1-4 hours; performing standing, extraction filtration, cleaning and drying obtain the fragrance-containingmicrocapsules. The fragrant tows are added into a heat-not-burning cigarette filter, fragrance is slowly released when high-temperature smoke passes, so that the fragrance of heat-not-burning cigarettes is lasting, smoke temperature is reduced, and consumers can achieve better sensual experience.

Description

technical field [0001] The invention relates to a preparation method and application of floral-flavored tow used in novel heat-not-burn tobacco, belonging to the field of novel tobacco. Background technique [0002] Heat-not-burn tobacco is a new type of tobacco product that heats shredded tobacco through a special heating source. When heating, nicotine and flavoring substances in shredded tobacco volatilize to produce smoke to meet the needs of smokers. One of the major changes in heat-not-burn cigarettes compared to conventional cigarettes is the lower ambient temperature of the tobacco material during consumption. The combustion cone temperature of traditional cigarettes can reach up to 950°C, and cigarette shreds can form thousands of products through complex reaction pathways such as distillation, cracking, and combustion; for heat-not-burn cigarettes, the temperature of the tobacco material is generally lower than 500°C, and the smoke is mainly generated through the p...
