Description

Technical Field

[0001] This invention belongs to the field of burst bead processing technology, specifically relating to a burst bead that slows down the drop in crushing pressure and its preparation method. Background Technology

[0002] Cigarette flavor capsules are made by encapsulating various tobacco flavorings in liquid form within tiny, sealed spherical capsules using natural or synthetic polymer materials. The application of flavor capsules in cigarette filters allows for adjustable cigarette flavor, significantly enhancing aroma and moisturizing the cigarette. This satisfies consumers seeking a unique cigarette aroma and provides a pleasant smoking experience with comfort, sweetness, and salivation. The popping of the flavor capsule creates a powerful visual impact, adding a fun and engaging element to the cigarette experience.

[0003] Existing technology for burst beads mostly uses brittle wall materials, primarily formulated with raw materials such as seaweed gum, gum arabic, plant gum, plant polysaccharides, and chitosan in certain proportions. After being stored for half a month or more, the brittleness of the droplets increases, and the average breakage pressure of the burst beads decreases by 0.4 kg or more, with over 20% weighing less than 1.0 kg, making them prone to breakage and failing to meet burst bead standards. Furthermore, for burst beads with a size of 2.6mm-2.9mm, the proportion of agglomerated beads is very high during production. Conventional formulas can only control this agglomeration to a minimum of 7%, severely impacting the yield of 2.6mm-2.9mm burst beads, making it difficult to achieve a yield of 90%. The main reason for the agglomeration of burst beads is that collisions and gel adhesion occur during the dripping and curing processes. Moreover, the particle size qualification rate of burst beads produced with conventional formulas is difficult to reach 90%, severely affecting the yield and processing speed. The low particle size qualification rate is mainly due to deformation caused by the compression and collision between the burst beads and the wall material adhesive during the dripping and curing processes. Summary of the Invention

[0004] To address the problems existing in the prior art, the present invention aims to provide a bursting bead that reduces the drop in crushing pressure and is less prone to forming fused beads during the preparation process, as well as a method for preparing the same.

[0005] To achieve the above objectives, the present invention employs the following technical means: a bursting bead that slows down the drop in crushing pressure, comprising a core liquid and a wall material, wherein the raw materials used in the core liquid are formulated in the following proportions by weight: 100 parts deionized water, 1-5 parts anhydrous calcium chloride, 0.5-2 parts sodium carboxymethyl cellulose, 1-3 parts surfactant, and 200-300 parts essential oil.

[0006] The raw materials used in the wall material are formulated in the following proportions by weight: 100 parts deionized water, 1.5-2 parts sodium alginate, 0.5-1 parts carrageenan, 0.1-0.5 parts polyethylene glycol, 0.1-0.5 parts ethyl cellulose, 0.1-0.5 parts oxidized starch, 0.1-0.3 parts sorbitol, 0.1-0.5 parts glycerin, 0.1-0.3 parts surfactant, and 0.01-0.05 parts chelating agent.

[0007] The polyethylene glycol is PEG4000 and PEG6000.

[0008] The surfactant is selected from one or more of Tween 80, carbomer, and poloxamer.

[0009] The chelating agent is selected from one or more of sodium gluconate, inositol hexaphosphate, and sodium hexametaphosphate.

[0010] To enhance the color of the capsules, improve their visual appeal, and facilitate identification, a dyed film layer is also coated on the outside of the wall material. The raw materials used in the dyed film layer are formulated as follows by weight: 0.1-0.5 parts pigment, 0.1 parts adhesive, 0.2 parts HPMC, and 100 parts deionized water.

[0011] The pigment is one or more of lemon yellow, carmine, and brilliant blue. The binder is pullulan or chitosan.

[0012] The preparation method includes the following steps:

[0013] A. Preparation of core solution: Mix and stir the core solution materials until completely dissolved, evenly dispersed, without layering, without oil seepage, with good stability, and control the viscosity of the solution to 30000±2000 mpa.s, temperature to 20-30℃ and fluidity.

[0014] B. Preparation of wall material adhesive: Accurately weigh the wall material materials to ensure complete dissolution, stir evenly, clarify and eliminate bubbles, and control the temperature of the liquid at 20±2℃, viscosity at 300±50mpa.s, and fluidity.

[0015] C. Droplet shaping: The wall material adhesive from step B is placed in a beaker and rotated. The core liquid from step A is dripped into the rotating wall material adhesive at a certain rate through a specific dropper. Under the action of gravity and rotational force, the core liquid falls into the adhesive. Calcium ions and sodium alginate undergo a cross-linking reaction to gel and form a film, thus forming popping beads.

[0016] D. Washing the pellets: Rinse the molding liquid off the surface of the bursting pellets in time;

[0017] E. Drying: Place the cleaned popping beads into a drying device to dry and dehydrate them. Control the drying temperature and humidity at 15-21℃, the drying time at 1.5-2.5 hours, and the relative humidity at 25-40% to ensure that the moisture inside and outside the popping beads reaches a relatively balanced state.

[0018] F. Dyeing: Based on the color of the customer's sample, a layer of uniformly colored dyeing film is coated on the surface of the capsule to increase the color of the food popping beads, enhance their appearance, make them easier to distinguish, and also enhance the fluidity and moisture resistance of the popping beads.

[0019] G. Drying, sorting, testing, packaging, and warehousing of pellets.

[0020] In actual production, the formation of intercalation is mainly due to the emulsion dripping into the adhesive solution, which initiates cross-linking and film formation. However, the emulsion sinks in the adhesive solution due to surface tension and the central vortex formed by rotation. Therefore, as the number of popping beads in the beaker increases, the probability of their collision increases. If the gelation speed is too fast, the probability of adhesion increases. The decrease in popping bead breakage pressure is mainly due to damage to the wall material by the core liquid and environmental damage to the wall material.

[0021] The present invention has the following beneficial effects: ① The crushing pressure is determined by the cross-linking reaction between calcium ions in the core liquid and the wall material. Therefore, the concentration of calcium ions in the core liquid affects the crushing pressure of the popping beads. The carrageenan, PEG, and ethyl cellulose in the present invention will increase the toughness and density of the wall material and reduce the damage of the core liquid to the wall material. The addition of oxidized starch to the wall material will increase the antioxidant capacity of the wall material and reduce the damage of the environment to the wall material.

[0022] ② This invention uses calcium ions in the core liquid to diffuse and crosslink into the wall material adhesive to form a film. The addition of chelating agent can slow down the crosslinking reaction between sodium alginate and calcium ions, and reduce the gel strength of the wall material adhesive, thereby slowing down the film formation speed. A uniform film is formed layer by layer from the inside out. Even if the popping beads collide, they will not form a film and stick together instantly, which solves the problem that the fast gel speed hinders the outward diffusion of calcium ions to form a connected body.

[0023] ③ Reducing the solids concentration of the wall material adhesive improves its fluidity and lowers the probability of collisions. Increasing the surfactant reduces the surface tension of the adhesive, decreasing the pressure exerted by the wall material adhesive on the burst beads, thus ensuring the qualified particle size of the burst beads. PEG4000 binds water molecules through hydrogen bonds, and when used in combination with PEG6000, it further enhances the toughness of the wall material.

[0024] ④ A thin film of uniform color is wrapped around the surface of the capsule to increase its color, enhance its visual appeal, make it easier to distinguish, and also enhance its fluidity and moisture resistance. Detailed Implementation
