Aroma-flavored sustained-release gel particles for cigarette filter stick, preparation and application thereof

Abstract

The invention relates to aroma-flavored sustained-release gel particles for a cigarette filter stick, preparation and application thereof. The preparation method comprises the steps that 10%-30 % of polycaprolactone, 40%-70 % of palmitic acid, 19%-30% of myristic acid are evenly mixed by mass and dissolved at the temperature of 40-70 DEGC to obtain a gel solution, then aroma not more than 10% of the gel solution by mass is added to obtain aroma-flavored sustained-release gel melt with the viscosity of 50-500 mpa.s, and spray drying and granulation are executed. The prepared particles can effectively increase the aroma storage effect, aroma release uniformity and stability of the particle filter stick. The aroma-flavored sustained-release gel particles can effectively and uniformly dispersearomatic substances, reduce volatilization loss of aroma and effectively release aromatic smell, raw material selection and a production method are simple, the quality is easy to control, the appearance quality of the product is good, and large-scale production can be achieved.

Description

technical field [0001] The invention belongs to the technical field of cigarette auxiliary materials, in particular to a flavoring slow-release gel particle used for cigarette filter rods, and also relates to a preparation method and application of the flavoring slow-release gel particle. Background technique [0002] With the improvement of people's living standards, health awareness has also been strengthened. While smokers obtain physical and psychological satisfaction through smoking, they also hope to reduce the harm caused by smoking as much as possible. However, the technologies used today to reduce the harmful tar content in tobacco all reduce some flavor components of cigarette smoke to varying degrees, which affects the experience of smokers. Therefore, developing a low-harm cigarette that can not only meet the harm reduction needs of the majority of smokers, but also maintain the high aroma of cigarettes has become an important research topic in the tobacco indus...

AI Technical Summary

Problems solved by technology

Granular flavored filters have the advantages of low requirements on the properties of fragrance substances, novel and beautiful appearance, etc., but there are also defects such as volatilization of fragrance substances, short storage time of fragrance substances, less adsorption of fragrance substances, large loss of fragrance substances during processing, and low transmission efficiency.

[0004] (2) Explosive bead filter stick: it uses microcapsules or exploding beads in the filter rod, which has a good fragrance retention effect and is easy to store. The process of capsules or popping beads is relatively cumbersome, and it is also difficult to control the release pressure of microcapsules or popping beads, resulting in inconsistent rubber thickness in the same batch of microcapsules or popping beads, which makes some easy to pinch and some difficult to pinch. The final filter rod structure is relatively complex, resulting in relatively high production costs, usually only suitable for high-end cigarettes, and the scope of application is small

In addition, the current national policy restricts the addition of popping beads or microcapsules, which has a certain negative impact on its application prospects

[0005] (3) Gel filter rods: showing a good development momentum, but there are certain technical difficulties, the production speed is slow, and the production efficiency is low

[0006] (4) Filter stick with incense thread: its structure and manufacturing process are simple, but the fragrance is volatile, the fragrance storage time is short, and the fragrance storage effect is not good

[0007] In addition, Chinese patent CN201210385682.3 discloses a granular material for cigarette filter rods and its preparation method. This method is improved on the basis of traditional starch granules, but this method first has strict requirements on the index of the selected material and complicated process. It is difficult to control the production operation, it is difficult to realize large-scale production, and the fragrance preservation and release effect of the obtained products are not good

CN201610764049.3 discloses a composite gel fragrance slow-release granule and its preparation method and its application. It has been improved on the basis of CN201210385682.3 patent, which solves the problems of harsh material selection and complicated process. The release has been greatly improved, but there are still problems such as cumbersome selection of raw materials, high production costs, and relatively complicated processes. There is still a lot of room for improvement in fragrance retention and fragrance release.

[0008] Generally speaking, the current functional granules are concentrated in Chinese herbal medicine granules, activated carbon granules, etc., most of which are loose or over-dense in shape, and the fragrance is easy to volatilize
