New Functions and Possibilities
in a Single Capsule
Seamless capsules are a next-generation capsule technology that allows a variety of contents and shell structures to be designed within a single spherical capsule.
In particular, Double Capsules and Triple Capsules precisely control multiple layers within a single structure,
enabling multi-functionality, controlled release, ingredient protection and complex flavors that are difficult to achieve with a single capsule.
Seamless capsule technology forms the contents and shell liquid simultaneously through concentric multi-nozzles,
producing uniform spherical capsules by utilizing the surface tension of liquids and the gelling and hardening properties of the shell.
Double Capsule
Basic Structure
- Outer Shell
- Inner Core / Active Ingredient
- Outer LayerProtection and control of release properties
- Inner CoreKey flavors · Oils · Functional ingredients
※ Shell composition and thickness can be adjusted as needed
- Outer Layer
- Protection and control of release properties
- Inner Core
- Key flavors · Oils · Functional ingredients
Advantages
Protection of Internal Ingredients
- The outer shell protects the internal ingredients and can be used to enhance stability against oxygen, moisture and the external environment.
- In particular, it can be designed to reduce the diffusion of volatile ingredients such as flavors and to improve preservation.
- A basic capsule that protects active ingredients from the external environment and improves ease of handling
Product Design with Diverse Properties
- Products with a variety of properties can be designed by adjusting the shell composition, thickness and dissolution characteristics.
High Yield and Cost Efficiency
- The contents and multiple protective layers are simultaneously extruded and formed through a single coaxial nozzle, without complex multi-step processing.
- Not only is production overwhelmingly fast, but there is no leftover shell waste as in conventional methods, allowing nearly 100% of raw materials to be used.
Triple Capsule
Basic Structure
- Outer Layer
- Middle Layer
- Inner Core
- Outer LayerExternal protection and release control
- Middle LayerAuxiliary functional ingredients or an additional protective layer
- Inner CoreKey flavors · Oils · Functional ingredients
- Outer Layer
- External protection and release control
- Inner Core
- Key flavors · Oils · Functional ingredients
- Middle Layer
- Auxiliary functional ingredients or an additional protective layer
Advantages
Separate Design for Multiple Ingredients
- Ingredients that are difficult to mix, or that have different functions, can each be placed in separate regions.
Staged Release and Functional Capsule Development
- By designing different shell properties for each layer, the release timing or release rate of each ingredient can be differentiated.
- Going beyond simple content protection, protective layers, functional layers and active ingredient layers can be combined to develop high-performance delivery systems.
Maximized Barrier Protection
- Multiple barriers can increase the protection of functional ingredients.
