Embodiment 1

[0078] Weigh 12 g of polyvinyl alcohol and dissolve it in 400 mL of deionized water at 80°C to obtain a polyvinyl alcohol solution.

[0079] Weigh 3 g of polylactic acid particles and dissolve in 30 mL of methylene chloride to obtain a polylactic acid solution.

[0080] The polylactic acid solution and the maltol aqueous solution (with a maltol concentration of 1% mass fraction) were respectively put into syringes, placed on two syringe pumps, connected to the coaxial double-needle reactor, and the flow rates of the two syringe pumps were 5mL / h (maltol aqueous solution), 8mL / h (polylactic acid solution), drop into the polyvinyl alcohol solution, mechanically stir for 6h, the stirring speed is 250r / min, the product is vacuum filtered, washed with deionized water, and then collected , The polylactic acid flavored capsule is obtained. The particle size of the capsule is 3mm.

Embodiment 2

[0082] Weigh 12 g of polyvinyl alcohol and dissolve it in 400 mL of deionized water at 80°C to obtain a polyvinyl alcohol solution.

[0083] Weigh 3.6 g of polylactic acid particles and dissolve them in 30 mL of dichloromethane to obtain a polylactic acid solution.

[0084] Put the polylactic acid solution and deionized water into the syringes, put them on two syringe pumps, connect the coaxial double-needle reactor, and the flow rates of the two syringe pumps are 5mL / h (deionized water) and 8mL / h respectively (Polylactic acid solution), drop into the polyvinyl alcohol solution, mechanically stir for 6h, the stirring speed is 250r / min, the product is suction filtered under reduced pressure, washed with deionized water, and then collected to obtain a water-in-polylactic acid capsule. The measured particle size of the water-in-capsule is 3.2mm (see image 3 -a). The average water content of the capsule is 25.1 mg (water accounts for 73% by weight of the capsule weight), and the wat...

Embodiment 3

[0086] Weigh 12 g of polyvinyl alcohol and dissolve it in 400 mL of deionized water at 80°C to obtain a polyvinyl alcohol solution.

[0087] Weigh 4.5 g of polylactic acid particles and dissolve them in 30 mL of dichloromethane to obtain a polylactic acid solution.

[0088] Put the polylactic acid solution and deionized water into the syringes, put them on two syringe pumps, connect the coaxial double-needle reactor, and the flow rates of the two syringe pumps are 5mL / h (deionized water) and 8mL / h respectively (Polylactic acid solution), drop into the polyvinyl alcohol solution, mechanically stir for 6h, the stirring speed is 250r / min, the product is suction filtered under reduced pressure, washed with deionized water, and then collected to obtain a water-in-polylactic acid capsule. The particle size of the water-in-capsule is about 4mm (see image 3 -b), the average water content of the capsule is 35.3 mg (water accounts for 63% of the weight of the capsule).

Abstract

The invention relates to the field of cigarette additive materials, and particularly discloses a flavoring capsule. A core material of the flavoring capsule is a solution containing flavors and fragrances, and a wall material is polylactic acid. The invention further discloses a preparation method of the flavoring capsule. The preparation method comprises the steps: the solution containing the flavors and the fragrances serves as a core material solution; an organic solvent dissolved with the polylactic acid serves as a wall material solution; the core material solution and the wall material solution are immiscible; and the core material solution and the wall material solution are dropwise added into a solidified solution together through an inner hole of an electrostatic spinning coaxialsyringe needle (also short for the coaxial syringe needle), and a gap between the inner hole and an outer hole of the coaxial syringe needle correspondingly, after stirring, solid and liquid separation, washing and drying are conducted, and the flavoring capsule is obtained. The invention further provides application of the flavoring capsule. Compared with a previous flavoring capsule, steps are simple, using of a waxy material is avoided, multi-layer packing is not needed, and the cladding effect can be achieved; and the method is particularly suitable for cladding of the non-lipid-solubilityflavors and fragrances.

Description

Technical field [0001] The invention relates to the field of tobacco industry, in particular to a method for preparing flavored capsules. Background technique [0002] Adding flavors and fragrances to cigarettes has the effect of improving the physical and chemical properties of cigarettes, mellow aroma, and giving products different styles. [0003] The existing flavor adding method is mainly to add flavor to the cut tobacco. This method has the shortcomings of short residence time of flavor and uneven release. [0004] Another method is to prepare nano or millimeter capsules by coating flavors and fragrances. Among them, the millimeter-level capsules can be squeezed manually by consumers during the suction process to release the fragrance and enrich the taste. For example, the Chinese Patent Publication No. CN103045360A The literature discloses a cigarette filter stick flavor capsule, which is characterized in that it includes dry calcium alginate gel beads, the calcium alginate g...
