Jet Milling in the Food Industry: Maximum Precision for Ultra-Fine Powders

In the food industry, jet milling – also known as fluid energy milling – is becoming increasingly important. Whether for functional ingredients, flavor carriers, or texture enhancers, the demand for ultra-fine, homogeneous powders is rising. But what exactly is this process – and what role does contract manufacturing play in this context?

What is Jet Milling?

Jet milling is a high-precision grinding process that operates entirely without mechanical milling tools. Instead, compressed air is accelerated through special nozzles into the grinding chamber. The product is caught in this air stream, causing the particles to collide at high speeds and break down into increasingly smaller fragments. The result: microfine, homogeneous powders with exceptional purity.

Benefits of Jet Milling at a Glance

A key advantage: Since no solid tools come into contact with the product, there is no mechanical wear. This makes the process particularly suitable for hard or purity-sensitive materials, which are often found in the food industry.

  • Ultra-fine particle sizes in the single-digit micron range
  • No thermal stress – ideal for temperature-sensitive ingredients
  • Gentle grinding without metal contamination
  • High purity and product safety

Therefore, met milling is especially in demand for the micronization of proteins, plant extracts, functional fibers, dietary fibers, mineral salts, or natural colorants.
