Description
Technical field
The invention belongs to be sustained tobacco aromaticss processing technique field, it is related to being sustained the preparation of tobacco aromaticss microcapsules and answers
With.
Background technique
Increase with people to smoking and health problem attention rate, tobacco business gradually develop to low tar direction, but
It is that will appear the fragrance of tobacco itself to be filtered or diluted, fragrance is insufficient, therefore will pass through perfuming cigarette and be used to make up these damages
It loses, and does not increase tar yield.Tobacco aromaticss are embedded in microcapsules by the current mainly flavoring by way of microencapsulation
In, stimulation of the tobacco aromaticss by external environment can be reduced, the stability of tobacco aromaticss is effectively improved, while reducing its height
Volatility lengthens the residence time.The preparation method of microcapsules includes physical method, physical-chemical process and physical method at present, and cigarette is used
Spray drying process is widely used in fragrance, but high temperature during this will lead to that fragrance volatilization loss is larger, fragrance distortion, and
There are embedding rates it is low, microballoon shape is uncontrollable, complicated for operation, preparation cost is high the problems such as.
Porous-starch, which refers to, forms starch granules from outward appearance to inner essence through particle table by physics, chemistry or biological method
In hole, a kind of converted starch with honeycomb structure, be called and do micropore starch.The generation of porous structure makes starch granules
Specific surface area substantially increases, and Kong Rong is up to 50%, and adsorption capacity enhances, therefore porous-starch is a kind of novel absorption material, tool
The advantages that useful environmentally friendly, raw material sources are extensive, cheap, organic nonhazardous, it can be used as tobacco aromaticss microcapsules
Slow controlled release carrier.But in practical applications, since porous-starch surface is covered with hydrophilic hydroxyl, so that absorption oily perfume
Ability much decline.
Summary of the invention
Technical problem: a kind of micro- for being sustained tobacco aromaticss the purpose of the present invention is overcoming the deficiencies of the prior art and provide
Capsule product.It uses modified porous starch as carrier material, adsorbs tobacco aromaticss, then encapsulated with sealing material, be made slow
Release tobacco aromaticss microcapsules；
A kind of technical solution: the mass component of sustained release tobacco aromaticss microcapsules of the invention are as follows:
Tobacco aromaticss 10%-30%
Modified porous starch 40%-60%
Sealing material 40%-60%.
Wherein:
The modified porous starch is that porous-starch is modified as acylated porous-starch, esterification by hydrophobic chemical modification
Arbitrary one or more combination in porous-starch or esterified cross-linked porous starch.
The sealing material is ethyl cellulose, polyethylene vinyl acetate, polymethyl methacrylate, polylactic acid or poly-
Arbitrary one or more of combination in lactic-co-glycolic acid.
The tobacco aromaticss include natural tobacco aromaticss and synthesis tobacco aromaticss.
The preparation methods of sustained release tobacco aromaticss microcapsules of the invention the following steps are included:
Step 1, modified porous starch, sealing material are crushed respectively in pulverizer, is sieved；
Step 2, in a solvent by tobacco aromaticss dispersing and dissolving, adsorbed, adsorbed under room temperature uniform with modified porous starch；
Step 3, the above-mentioned porous-starch carrier for being adsorbed with tobacco aromaticss is mixed with sealing material, is formed by sealing material
The porous-starch Vehicles Microcapsules with tobacco aromaticss of encapsulating；
Step 4, solvent is removed, dry sustained release tobacco aromaticss microcapsules are obtained.
Wherein,
Sieving was 200-7000 mesh described in step 1.
Solvent described in step 2 is arbitrary one or more of in ethyl acetate, ethyl alcohol or propylene glycol.
Entirely absorption, encapsulation process are in vacuum state in step 2, step 3.
The microcapsules of formation can be allowed to therefrom slow release as the storage cavern of tobacco aromaticss, reduce the volatilization of tobacco aromaticss
Property, and load factor, the low advantage of burst release rate.It is fixed in outer layer cigarette paper using the adhesiveness of microcapsules sealing material, it can be into
Row seam, packaging, printing trade mark etc..
Porous-starch prepared by the present invention has large pore spherical structure, can be used for adsorbing tobacco aromaticss, and use sealing material
Its surface is wrapped up, extends the storage period of fragrance in the case where not losing tobacco aromaticss, improves slow release effect.
The utility model has the advantages that compared with prior art, the invention has the following advantages that
1, the carrier material selected by the present invention is modified porous starch, and entire adsorption process is in vacuum state, greatly
It is big to increase adsorbance.
2, the sealing material selected by the present invention is macromolecule filming jointing material, nontoxic, harmless, non-environmental-pollution,
Chemical property is more stable, does not react with tobacco aromaticss.
3, the present invention utilizes micro-capsule package technology, first adsorbs tobacco aromaticss with modified porous starch, and use sealing material again
Material is wrapped up, and has both been effectively prevented tobacco aromaticss process and has been dealt with improperly, has led to volatilization loss；It is unstable that fragrance is reduced again
It is fixed, the problem of interaction with other compositions.
4, sustained release tobacco aromaticss microcapsules prepared by the present invention can be allowed to therefrom slowly release as the storage cavern of tobacco aromaticss
It puts, reduces the volatility of fragrance, and load capacity is high, the low advantage of burst release rate.
5, sustained release tobacco aromaticss microcapsules produced by the present invention, not only economical and effective, but also can limit to the maximum extent
The volatilization of tobacco aromaticss in production process, meaning and value with actual production.
6, application of the microcapsules of the present invention in preparation cigarette, is fixed on outer layer using the adhesiveness of microcapsules sealing material
In cigarette paper, it can be not only sustained fragrance, seam, packaging, printing trade mark etc. can also be carried out.
