As consumers’ demands for the sensory quality and safety attributes of cigarettes continue to rise, burst bead technology has become a core area for innovation in the tobacco industry. And in the "heart" of burst beads — the field of core solvents — MCT, with its irreplaceable performance advantages, is gradually reshaping industry standards and emerging as a key link connecting technological innovation and user experience. Today, we will take an in-depth look at how MCT injects "stability genes" and "safety codes" into burst bead cigarettes.

First Introduction to MCT: Why Can It Become the "Preferred Choice" for Cigarette Burst Bead Solvents?

MCT is an extract derived from coconut oil and palm oil. Due to its short molecular chains and stable physicochemical properties, it is hailed as the "Liquid Gold" in the solvent field. Compared with traditional cigarette burst bead solvents such as glycerol and triacetin, its "standing out" is by no means accidental, and its core lies in three key strengths:

No Shortcomings in Basic Performance:

MCT inherently possesses the "neutral characteristics" of being colorless and odorless, which can perfectly avoid the interference of the solvent itself on the flavor of essences. Its viscosity at 20℃ is much lower than that of common vegetable oils, and it has a high boiling point and extremely strong oxidative stability (its viscosity shows almost no change after heating at 230℃ for 24 hours). This not only protects essences from deteriorating during storage bu t also withstands the high-temperature impact during cigarette combustion, ensuring the stability of the burst bead contents from the source.

Withstands Extreme Environments:

Traditional solvents such as glycerol tend to precipitate crystals at 5℃, causing burst beads to become ineffective in low-temperature environments. However, MCT has a freezing point as low as -40℃ and can remain in a liquid state even in frigid regions, completely solving the "geographical adaptation problem" of burst bead products.

Strong Endorsement for Safety and Compliance:

As a food-grade raw material compliant with the National Food Safety Standard GB2760-2014 (Standards for the Use of Food Additives) and certified by the FDA, MCT has clear regulatory support for its application in the tobacco industry. More importantly, studies have confirmed that during the combustion and pyrolysis of cigarettes, the content of harmful aldehyde compounds (such as formaldehyde) produced by MCT is 15%-20% lower than that of triacetin, and its residues are also reduced by more than 30%, which accurately aligns with the industry's development direction of "reducing tar and harm".

MCT's "Practical Application Value": Comprehensive Empowerment from Flavor to Function

If basic performance is MCT’s "stepping stone" (to entering the burst bead system), then its functional applications in the burst bead system are the real core that enhances product competitiveness. Currently, MCT has evolved from a "simple solvent" to a dual engine of "flavor optimization + functional expansion":

1. Sensory Experience: Making Aroma "Stronger, Longer-Lasting, and More Precise"

Aroma Enhancement and Boosting for Fragrances：Through molecular distillation technology, MCT (Medium-Chain Triglycerides) enables "top note enrichment" of natural fragrances such as rose essential oil and cocoa tincture. After diluting the fragrance by 1 to 50 times and subjecting it to distillation, the aroma intensity can be increased by over 30%. This process has been applied in a variety of high-end flavor beads, allowing consumers to more clearly perceive delicate flavors.

Upgrade of Release Efficiency：With a surface tension of less than 30 mN/m, MCT can quickly wet the cellulose acetate filter rod after the flavor bead ruptures, accelerating the migration of fragrances to the mainstream smoke. Comparative experiments show that compared with conventional solvents like glycerin, the fragrance-carrying system based on MCT has higher aroma release efficiency, and the fragrance retention time can be extended to 1.7 times that of conventional solvents, completely solving the problem of "fleeting flavor".

2. Functional Expansion: Building a "Dual-Function" Flavor Bead System

The solubility and extraction capacity of MCT also endow flavor beads with more possibilities. For instance, a relevant patent by China Tobacco Yunnan Industrial Co., Ltd. utilizes MCT to perform "targeted extraction" of cocoa powder under mild conditions of 60-80°C. Combined with ultrasonic assistance and vacuum distillation, polyphenol-enriched substances are extracted. By compounding this extract with ingredients such as baicalin, a dual-function flavor bead with both "antioxidant (efficiency increased by 40%) + flavor enhancement" can be created, endowing the product with an additional layer of value beyond sensory experience.

Case Studies: MCT is Redefining Burst Bead Product Standards

MCT's advantages are no longer "theoretical values" in the laboratory, but "practical values" verified by industrial practice:

After introducing the MCT solvent system, an international tobacco brand saw the breakage rate of burst beads drop directly to below 0.5%, while the consistency of aroma release increased by 40% — significantly reducing production losses and quality fluctuations.

Domestic enterprises, on the other hand, have combined MCT with nano-emulsification technology to achieve "dual-chamber layered release" of burst beads. For instance, the beads first release a cool sensation and then a fruit aroma, endowing the smoking experience with a stronger sense of layering.

MCT is set to kick off the "Multifunctional Era" of crushable beads

As the tobacco industry's demand for the "multifunctionality" of crushable beads continues to escalate, the application boundaries of MCT (Medium-Chain Triglycerides) are constantly expanding:

Functional crushable beads: Drawing on MCT's experience as a pharmaceutical solvent (e.g., in fat emulsion injections), it will be possible in the future to load ingredients such as melatonin and vitamins into crushable beads, developing functional tobacco products for sleep aid and nutritional supplementation.

Adaptation to new-type tobacco: MCT's low-temperature stability and thermal stability make it an ideal solvent for crushable beads used in heat-not-burn (HnB) cigarettes and e-cigarettes. It not only reduces the risk of high-temperature carbonization of atomizers but also ensures the efficiency of aroma mass transfer, providing support for the innovation of new-type tobacco.

Industry experts predict that in the next 3 years, the penetration rate of MCT in the field of crushable bead solvents may exceed 60%, making it an undisputed mainstream choice.

Conclusion

From ensuring flavor stability to reducing health risks, from optimizing smoking experience to expanding functional boundaries, MCT is redefining the "ceiling" of crushable bead technology. For consumers, this means a more premium and reassuring experience; for the industry, MCT represents a crucial opportunity to drive the "health-oriented and functional" upgrading of tobacco products. In the future, with further technological iteration, what new possibilities will emerge from the "golden partnership" between MCT and crushable beads? We await with anticipation.
