Description

Technical Field

[0001] This invention belongs to the field of cigarette auxiliary materials technology, and relates to flavor capsules, and more particularly to a low-temperature resistant flavor capsule. Background Technology

[0002] Capsule pods consist of a rigid outer layer and a core liquid. The main function of the outer layer is to prevent flavor loss and to support and protect the capsule from damage. The outer layer of capsule pods is usually made of plant-based gums. When stored or used in winter or low-temperature environments, quality problems such as cracking, shrinkage, and collapse can occur, rendering the capsules unusable. These problems arise because the outer layer is in a solid state (a relatively hard gel state), while the core liquid is in a liquid state. Their thermal expansion and contraction rates differ; typically, the core liquid loses more volume than the outer layer. Therefore, at room temperature, a fully popped capsule will develop pores between the core liquid and the outer layer under low-temperature conditions. The moment these pores form is essentially a vacuum, and under atmospheric pressure, the outer layer cracks, shrinks, and collapses.

[0003] To ensure that the capsules can be used normally, insulated packaging is often used for their storage and transportation. However, this does not solve the problem of the capsules' resistance to freezing and cold, and there are still potential quality issues during use. Summary of the Invention

[0004] To address the shortcomings of the existing technology, the purpose of this invention is to disclose a low-temperature resistant popping bead that provides a "skeleton" to the popping bead rubber, allowing the rubber to remain intact under normal atmospheric pressure without being squeezed or deformed, thus maintaining the original shape of the popping bead and achieving a popping bead integrity rate of 99.95% at -40℃.

[0005] Technical solution

[0006] A low-temperature resistant bursting bead comprises an antifreeze rubber sheet and an antifreeze core liquid. The antifreeze rubber sheet is wrapped around the outer layer of the antifreeze core liquid. The antifreeze rubber sheet is composed of pure water, a structural filler, a thickener, a toughening agent, a reinforcing agent, and an antifreeze agent. By mass ratio, the structural filler: thickener: toughening agent: reinforcing agent: antifreeze agent is 88-95:1-3:3-8:0.1-0.5:5-12. The mass of pure water accounts for 90-98% of the total mass of the rubber sheet components, preferably 95%. The antifreeze core liquid is composed of a solvent, a fragrance, and an antifreeze compound agent. By mass ratio, the solvent: fragrance: antifreeze compound agent is 80-95:5-13:2-5.

[0007] In a preferred embodiment of the present invention, the structural filler is one or more of gellan gum, agar, gelatin or gum arabic, preferably a mixture of gellan gum and agar, with a mass ratio of gellan gum: agar of 4-8:3-5, more preferably 5-6:3-4.

[0008] In a preferred embodiment of the present invention, the thickener is sodium alginate or sodium carboxymethyl starch, preferably sodium alginate.

[0009] In a preferred embodiment of the present invention, the toughening agent is a mixture of glycerol and polyethylene glycol, wherein the mass ratio of glycerol to polyethylene glycol is 1-5:2-4.

[0010] The polyethylene glycol is one or more of PEG400, PEG600 and PEG1000, preferably a mixture of PEG400 and PEG600, with a mass ratio of PEG400:PEG600 of 4-8:3-5.

[0011] In a preferred embodiment of the present invention, the reinforcing agent is anhydrous calcium acetate or anhydrous potassium citrate, preferably anhydrous calcium acetate.

[0012] In a preferred embodiment of the present invention, the antifreeze is a mixture of ultrafine zeolite powder, silicon dioxide, and anhydrous potassium aluminum sulfate; preferably, it is a mixture of silicon dioxide and anhydrous potassium aluminum sulfate with a mass ratio of silicon dioxide to anhydrous potassium aluminum sulfate of 1:2.

[0013] In a preferred embodiment of the present invention, the solvent of the antifreeze core fluid is a mixture of caprylic / capric glyceride and triacetic acid glyceride, with a mass ratio of caprylic / capric glyceride: triacetic acid glyceride of 6-10:1-5, preferably 6-8:1-3.

[0014] In a preferred embodiment of the present invention, the fragrance is an oil-soluble fragrance.

[0015] In a preferred embodiment of the present invention, the antifreeze compound is an aqueous solution of calcium acetate and potassium chloride with a concentration of 0.1-2 wt%, preferably 0.3-0.8 wt%, wherein the mass ratio of calcium acetate to potassium chloride is 1-3:2-5, preferably 2:3-5.

[0016] Since the solvent of the antifreeze core fluid and the antifreeze compound are immiscible, they need to be emulsified using a shear emulsification method. The emulsification process is as follows:

[0017] The stator hole size is 0.3–1.0 mm. 2 0.5mm is preferred 2 .

[0018] The shear emulsification rate is 15,000 to 24,000 rpm, preferably 18,000 to 21,000 rpm.

[0019] During the shear emulsification process, the system temperature is controlled at 22–28℃.

[0020] The aforementioned antifreeze rubber and antifreeze core liquid are placed in a popping bead dripping machine to produce popping beads with a particle size between 1.0 and 6.0 mm.

[0021] This invention adds a skeletal structural material to the original rubber formula, improving the rubber's pressure resistance at low temperatures, thereby increasing its preservation rate at low temperatures and giving it good antifreeze properties. Furthermore, an antifreeze composite agent is added to the core material to reduce the amount of material lost during low-temperature testing.

[0022] Beneficial effects

[0023] The low-temperature resistant bursting beads disclosed in this invention increase the compressive strength of the bursting beads when the volume of the core fluid shrinks, resulting in internal cavities, by adding an inorganic salt "skeleton" to the rubber shell. This reduces capsule pitting, collapse, and cave-in. Furthermore, the addition of an antifreeze complex to the core fluid reduces excessive shrinkage or expansion, preventing the bursting beads from rupturing. Detailed Implementation
