Description

Alkali modified visual coloring flavor sustained-release particles and preparation method and application thereof
Technical Field
The invention belongs to the field of cigarette manufacturing, particularly relates to alkali modified visual coloring flavor sustained-release particles and a preparation method and application thereof, and particularly relates to alkali modified visual coloring flavor sustained-release particles with a good appearance effect and a preparation method and application thereof.
Background
With the advance of tar and harm reduction, the tar content in cigarette smoke is continuously reduced, and the requirements on cigarette aroma enhancement and supplement technologies are higher and higher, so that the research and development of the filter tip aroma enhancement and supplement method are rapidly developed, and the technologies including tow aroma enhancement, aroma line, bead explosion, dropping pill, microcapsule, nanoparticle and the like are developed and applied. However, these techniques have certain disadvantages, such as poor long-term storage fragrance stability of filament bundles and aromatic threads, high cost of bead blasting and dropping pills, and introduction of other unpleasant odors, and potential safety hazard of lung inhalation of microcapsules and nanoparticles. New technologies of flavor slow-release particles have recently been developed in the industry, such as flavor slow-release agent particles for cigarette filters (201510300776. X, 201610488221.7), porous solid flavor beads for cigarettes (201910888311.9), large particle solid flavor bead cigarette filter sticks (201810886849.1, 2018000887493.3, 201810887483.x, 2019000314422.9, 201910314412.5, 201810885888.x, 201811016014.7) and the like.
However, the existing technology for manufacturing the aroma slow-release particles has some defects: granulating by adopting a common extrusion method, a spray drying method, a granulator granulation method and the like, wherein the obtained granules have small granularity, low roundness and slightly poor hardness; if the granularity or roundness is improved, the production cycle is greatly prolonged, and if the hardness of the particles is ensured, the density is increased and the essence adsorption capacity is reduced; by adopting the improved large-particle granulation method, although the granularity and the roundness of the obtained particles are obviously improved, the production period is as long as 2-4 days, and the batch preparation capability is weak. In addition, the particles prepared by the prior art have dark color, or colorless/light color, or poor color uniformity, so the appearance character is not good, and the particles are not suitable for manufacturing visual filters. Therefore, how to provide a filter tip aroma enhancement and supplement product with good appearance effect, simple and quick preparation process and good essence adsorption capacity becomes a problem to be solved urgently.

the data show that the product provided by the invention can effectively improve the quality of smoke, endow the cigarette with more obvious additional fragrance, and has no great negative influence on the harmony of the smoke.
Evaluation of fragrance sustained-release capability:
cigarette samples prepared by the sensory evaluation are taken as objects (filter flavoring is carried out on blank samples in a tow spraying mode), a rotary disc smoking machine (model RM20H manufactured by Borgwoldt KC Instrument company) is adopted, and tar, nicotine and moisture on the cigarette mouth-by-mouth smoke trapping filter sheet are measured by referring to GB/T19609-2004, GB/T23203.1-2008 and GB-T23355-2009. Referring to YCT 286-2009, the content of the flavor components on the cigarette mouth-by-mouth smoke trapping filter sheet is determined by an external menthol sample preparation mode (the flavor and the aroma in all particles are replaced by the same amount of menthol). The matching of the visual granular flavor slow-release capacity and the smoke is analyzed by adopting the ratio of the mouth-by-mouth flavor component ratio (single-mouth flavor component content/total flavor component content) to the mouth-by-mouth tar ratio (single-mouth tar content/total tar content):
Figure BDA0003800505160000151
according to the data, the matching performance of the fragrance component slow-release capacity and the mouth-to-mouth smoke concentration of the visual fragrance slow-release particles provided by the invention is good, except for the first mouth (ignition suction mouth), the ratio of the fragrance component concentration to the tar concentration is stabilized within the range of 0.82-1.17, the fragrance slow-release capacity is good, and the requirements of essence slow-release materials are met.
