The ability to accurately picture and describe the colour or structure of a food product provides the food manufacturer
with a valuable tool to improve quality. From consistent and accurate colour measurements of products such as fruit and vegetables, to detailed
descriptions of the crumb structure of bread and cakes, Campden BRI has a range of state-of-the-art equipment to do the job.
As well as our microscopy services, we also carry out:
- Accurate colour imaging using a DigiEye imaging system, calibrated against the CIELAB colour space. This includes image capture, screen
display ad printing. Images can be used for food specification, analysed to measure the colour distribution, and printed on a calibrated
printer for use in visual assessment.
- Non-destructive imaging of internal product structure using an X-ray CT scanner. A special
oven enables products to be baked inside the scanner, enabling structural changes to be studied during processing.
- Quantitative analysis of cellular product structure using the C-Cell instrument developed by Campden BRI.
Hyperspectral NIR imaging. This allows the chemical composition of products to be visualised. It clearly shows areas
where the composition is different – and thus is very useful for investigating the uptake of fat in fried products, such as doughnuts or chips.
The same technique can also be used to monitor moisture migration in bakery products, and help understand how they become stale over storage
Digital image analysis can be used to provide objective measurements of a wide range of characteristics, using images
from any of the above sources. Dedicated software and imaging systems can be developed for particular tasks.
