Food and feed analysis – Tailored sample preparation for reliable results

21 Oct 2026

Reliable food and feed analysis starts with representative, homogeneous samples. Differences in moisture, fat, texture, and sample size can make preparation challenging, with the wrong grinding approach potentially affecting sample properties and analytical results.

Explore how RETSCH milling and grinding solutions can tailor sample preparation to everything from sticky and fatty foods to grains, fibrous materials, and large sample volumes. See how techniques including cryogenic grinding and particle size reduction support efficient homogenization while preserving sample integrity. This means laboratories can prepare even challenging food samples effectively, laying the foundation for accurate, reliable analysis.
