micropeltes

Micropeltes is a term used to describe very small pellet-like particles produced by pelletization and related processing methods across several industries. The exact size and shape are not standardized, but micropellets commonly range from about 0.1 to 5 millimeters in diameter and can be spherical or irregular depending on materials and production methods.

Applications of micropellets span food technology, aquaculture feeds, and biotechnology. In aquaculture and pet-food contexts, micropellets enable precise dosing for early life stages, with attention to buoyancy, stability in water, and palatability. In food technology and nutraceuticals, micro-encapsulation using micropellets allows controlled release of flavors, vitamins, or bioactives. In biotechnology, micropellets can serve as carriers for immobilized enzymes or microbial cells, improving product separation and process efficiency.

Production and materials vary by application. Micropellets are typically produced by extrusion-spheronization, spray drying, or pelletization with binders. Materials used include polymers, ceramics, and bioactive compounds, selected for compatibility with the intended use. Key properties include size uniformity, density, mechanical strength, and porosity, all of which influence dissolution, diffusion, and handling characteristics.

Advantages of micropellets include increased surface area for mass transfer, potential for controlled release, and easier handling compared with bulk powders. Challenges encompass dust generation, breakage during processing or transport, moisture sensitivity, and regulatory considerations for food, feed, or pharmaceutical uses.
