In detail

Mesh size affects flowability, blending, capsule filling, suspension, and mouthfeel. An 80-mesh powder is common for capsule blends; a 200-mesh powder may be needed for a smooth drink or a fine dispersion. The relationship between mesh and micrometres is approximate and varies with wire diameter and the standard used.

Particle size should be a release parameter, not an afterthought. A lot that is coarser than the specification can segregate in a blend or feel gritty in a beverage. Ask for the mesh or micrometer range and the test method, and request a sample if mouthfeel matters.

Why it matters to a buyer

  • It affects whether a powder flows on a capsule line or cakes in a drum.
  • It changes suspension and mouthfeel in beverages.
  • Particle size can segregate in a blended formula if it differs between ingredients.

What to ask a supplier

01

What mesh or micrometre range is standard, and what is the tolerance?

02

How is particle size tested — sieve or laser diffraction?

03

Can you provide a finer or granulated grade for our process?
