X-ray micro-computed tomography (μCT) is a non-destructive technique for studying internal micro-structure in 3D – with sub-micron resolution. It’s also known as X-Ray Microscopy (XRM).
In the food industry, you can investigate the relationship between structure and properties in product development, as well as gaining insights into shelf life, etc. Analyse samples of any shape, including delicate foods, with little to no sample preparation.

Micro-CT can be used to measure and investigate these and much more:
Food Industry Areas
- New product development
- Reformulation trials
- Food product changes over time
- Shelf life determination
- Packaging (including defects)
- Porosity/ density
- Bubble size and distribution
- Fine walls in bakery products
Structure and Texture
- Structural characterisation
- Effects of processing
- Effects of ingredients and additives on structure
- Expansion and cracks – with sub-micron resolution
- Distribution of particles
- Moisture migration
- …and more
How Campden BRI use Micro-CT
Europe’s news network Euronews featured how micro-CT is used to analyse how seeds respond to stress tests, in order to select seeds that produce the maximum yield.
