Technical Field

The invention relates to the field of tobacco essence and flavor, in particular to a magnolia officinalis gel bead for tobacco and a preparation method thereof.

Background

The cortex magnoliae officinalis is a common traditional Chinese medicine, has the effects of relieving cough and eliminating phlegm, helping digestion and guiding qi downward, and eliminating dampness and harmonizing stomach clinically, is proved by pharmacology to have the remarkable effects of reducing blood pressure and inhibiting pathogenic microorganisms, and the cortex magnoliae officinalis volatile oil contains eucalyptol and isomers thereof, accounts for about 40-55% of the total amount of the volatile oil, is provided with alkenes, phenols and the like, has a fresh sweet fragrance in tobacco, is coordinated with the smoke, can well reduce the throat irritation caused by the smoke, and is a good cigarette spice.

The flavoring in the filter tip has the advantages that the flavoring of a plurality of cut tobaccos is incomparable, the essence added in the filter tip does not participate in combustion, and various toxic and harmful components can not be generated due to thermal cracking, so the filter tip is not limited by the license list of the tobacco additives, the relatively low-temperature suction condition can ensure that the fragrance of the fragrant raw materials is purer, however, the flavoring of the filter tip has a plurality of defects, the fragrance of the essence is easy to permeate outwards, the obvious external fragrance can be generated when the cigarette packet is disassembled, the essence is easy to dissipate, the fragrance is not lasting, and the like.

Disclosure of Invention

In order to solve the problems, the invention provides the magnolia bark gel bead for the cigarette and the preparation method thereof, and the magnolia bark gel bead has fresh, pungent and sweet fragrance when being added into a filter tip, can keep fragrance for a long time, reduces the stimulation of smoke to the throat, and has controllable fragrance intensity.

The technical scheme of the invention is that the magnolia bark gel bead for the cigarette comprises the following components: 0.5-5 parts of mangnolia officinalis volatile oil, 60-80 parts of polyethylene glycol, 10-20 parts of sodium stearate, 10-20 parts of propylene glycol, 30-50 parts of low-methoxyl-group pectin, 20-40 parts of calcium chloride, 5-10 parts of chitosan and 5-10 parts of guar gum.

Preferably, the molecular weight of the polyethylene glycol is 1000-.

Further, a preparation method of the magnolia bark gel bead for cigarettes is also provided, and comprises the following steps: s1, adding the volatile oil of cortex Magnoliae officinalis into the mixture of low methoxyl pectin, guar gum, sodium stearate and propylene glycol, shearing and emulsifying at high speed with span-80, adjusting pH to 7, dropping into calcium chloride solution, stirring, adding polyethylene glycol, and crosslinking and solidifying to obtain pre-compounded gel beads; s2, adding a sodium tetraborate solution, and curing at room temperature to obtain composite gel beads; s3, transferring the composite gel beads into a chitosan acetic acid solution for crosslinking and curing to obtain the magnolia bark gel beads.

Preferably, the preparation method of the magnolia officinalis volatile oil comprises the following steps: grinding cortex Magnolia officinalis to particle diameter of 2-10mm, soaking cortex Magnolia officinalis in distilled water at room temperature for 8-24 hr, distilling under normal pressure for 1-5 hr, condensing to recover distillate, and separating oil and water to obtain oil phase to obtain volatile oil of cortex Magnolia officinalis.

Preferably, the heating temperature of S1 is 85-95 ℃.

Preferably, the dropping rate of S1 is 2 ml/min.

Preferably, the screen filtering is further included between S2 and S3, and the aperture of the screen is 1-5 mm.

The main chain of the low methoxyl pectin consists of alpha-1, 4-glycosidic bond connected with D-galacturonic acid, and the side chain is L-

Rhamnose or feruloyl, wherein carboxyl on molecular chain can react with Ca²⁺、Ba²⁺The multivalent cations generate cross-linking action to form an egg lattice structure, and a core material mixed with the egg lattice structure, namely the magnolia volatile oil can be embedded, but the magnolia volatile oil is released quickly and leaves fragrance for a short time due to the porosity of the structure, so the scheme has the advantages ofIn order to reduce the porosity and prevent the leakage of the volatile oil of the mangnolia officinalis, chitosan which is a cationic polysaccharide and low-methoxyl pectin gel beads are utilized to form a polyelectrolyte complex through mirror interaction, so that the porosity is reduced, namely the chitosan is used as a polyelectrolyte composite membrane to form a plurality of layers of gel beads, and the fragrance retention time of the volatile oil of the mangnolia officinalis is prolonged.

Meanwhile, in order to improve the embedding rate of gel beads on the volatile oil of the mangnolia officinalis, the dispersion degree of the volatile oil of the mangnolia officinalis in the low-methoxyl pectin is very important, as the main component of the volatile oil of the mangnolia officinalis is eucalyptol and isomers thereof, and then alkenes, phenols and the like are added, and propylene glycol and polyethylene glycol are used as dispersion carriers, the compatibility of the volatile oil of the mangnolia officinalis and the low-methoxyl pectin is improved, so that the volatile oil of the mangnolia officinalis is uniformly dispersed.

Guar gum and mangnolia officinalis volatile oil are embedded in the low-methoxyl pectin gel together, after sodium tetraborate is added, the guar gum and the sodium tetraborate form semi-solid reversible acid gel, the guar gum and the low-methoxyl pectin form an interpenetrating network structure, and the comprehensive performances such as heat resistance, stability and the like are greatly improved.

Polyethylene glycol reacts with calcium chloride to form a coordination compound, according to the theory of a hybridization orbit and a coordination field, mainly because calcium ions react with-C-O-C-groups of the polyethylene glycol, the calcium ions attract electron clouds of oxygen in the-C-O-C-groups, lone pair electrons on oxygen atoms are partially transferred to outer empty orbitals of the calcium ions to form O-Ca coordination bonds, namely a coordination structure is formed, on one hand, the low methoxyl pectin is helped to consume redundant calcium ions, the problem that the concentration of the calcium ions is too high, and the permeability of gel beads is reduced due to too high gel strength is solved, on the other hand, compared with the gel beads, the polyethylene glycol has stronger fluidity, and can be extruded to permeate out of a polyelectrolyte composite membrane formed by chitosan, the fragrance strength can be controlled, when the fragrance strength is strong, squeezing the gel beads, wherein the volatile oil of cortex Magnolia officinalis is popped out with polyethylene glycol, and when the fragrance is desired to be lasting and light, the product is naturally sucked.

The invention has the beneficial effects that:

1. chitosan, a cationic polysaccharide, and low-methoxyl pectin beads are subjected to mirror interaction to form a polyelectrolyte complex, so that the porosity is reduced, multi-layer gel beads are formed, and the fragrance retention time of the magnolia officinalis volatile oil is prolonged;

2. propylene glycol and polyethylene glycol are added as dispersion carriers, so that the compatibility of the magnolia volatile oil and the low methoxyl pectin is improved, the magnolia volatile oil and the low methoxyl pectin are uniformly dispersed, and the embedding rate is further improved;

3. guar gum and sodium tetraborate form semi-solid reversible acid gel, guar gum and low methoxyl pectin form interpenetrating network structure, and the comprehensive properties such as heat resistance, stability and the like are greatly improved;

4. the polyethylene glycol and calcium chloride react to form a coordination compound, on one hand, the low methoxyl pectin is helped to consume redundant calcium ions, the problem that the gel bead permeability is reduced due to overhigh calcium ion concentration and overlarge gel strength is avoided, and on the other hand, the fragrance strength of the mangnolia officinalis is controlled when the product absorbs the water.
