Embodiment 1

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

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

[0080] The polylactic acid solution and the maltol aqueous solution (the concentration of maltol is 1% mass fraction) were respectively loaded 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, filter the product under reduced pressure, wash with deionized water, and then collect , to obtain polylactic acid flavored capsules. The particle size of the capsules was measured to be 3 mm.

Embodiment 2

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

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

[0084] Put the polylactic acid solution and deionized water into syringes respectively, place 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 6 hours, the stirring speed is 250r / min, the product is filtered under reduced pressure, washed with deionized water, and then collected to obtain water-in-polylactic acid capsules. The particle diameter that records water-packed capsule is 3.2mm (see image 3 -a). The average amount of water contained in the capsules is 25.1 mg (water accounts for 73 wt% of the weight of the...

Embodiment 3

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

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

[0088] Put the polylactic acid solution and deionized water into syringes respectively, place 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 6 hours, the stirring speed is 250r / min, filter the product under reduced pressure, wash with deionized water, and then collect to obtain polylactic acid-in-water capsules. The particle size of the water-packed capsule is about 4mm (see image 3 -b), the average capsule water content is 35.3mg (water accounts for 63% of the capsule weight).

Abstract

The invention relates to the field of cigarette additive materials, and specifically discloses a flavoring capsule, wherein the core material is a solution containing essence and fragrance; the wall material is polylactic acid. The invention also discloses the preparation method of the flavored capsules. The solution containing essence and fragrance is used as the core material solution; the organic solvent dissolved with polylactic acid is used as the wall material solution; the core material solution and the wall material solution are immiscible; The material solution is added dropwise to the coagulation liquid through the inner hole of the electrospinning coaxial needle (also referred to as the coaxial needle in the present invention), and the wall material solution is dropped into the coagulation liquid through the gap between the inner and outer holes of the coaxial needle, and the solid and liquid are separated after stirring. , Wash and dry. The invention also provides the application of the flavored capsule. Compared with the previous flavoring capsules, the present invention has simple steps, avoids the use of waxy materials, and can realize the coating effect without multi-layer wrapping; the method of the present invention is especially suitable for the coating of non-fat-soluble flavors 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] The effect of adding flavors and fragrances to cigarettes is to improve the physical and chemical properties of cigarettes, round aroma, and endow products with different styles. [0003] The existing method of adding flavor is mainly to add flavor to shredded tobacco. This method has the disadvantages of short residence time of flavor and uneven release. [0004] Another method is to prepare nano- or millimeter-sized capsules by coating flavors and fragrances. Consumers can squeeze the millimeter-sized capsules manually during the suction process to release the fragrance and enrich the taste. For example, the Chinese patent with the publication number CN103045360A The literature discloses a cigarette filter stick essence capsule, which is characterized in that: it includes dry calcium alginate gel beads cont...
