The structure of food influences texture. Examples include porous products such as aerated foods and bakery products
where the bubble structure affects softness, and starch-based snacks where it affects crispiness.
This instrument, originally developed at Campden BRI, allows rapid, quantitative analysis of cellular products. Parameters
such as wall thickness and cell diameter can be measured from a cut cross section, such as a slice of bread.
X-ray micro-CT offers non-destructive imaging and structure measurement in 3D. Images and movies showing the internal
structure of products can be generated. Measurements of porosity, bubble size distribution and structure thickness (wall size) can be performed.
A wide range of microscopy facilities are available including scanning electron microscopy (with energy dispersive X-ray
microanalysis capabilities for determining elemental composition), optical microscopy and FTIR microscopy. These techniques provide high
resolution images revealing product structure at a microscopic scale.
Dynamic imaging of baking
A medical CT scanner and special oven can be used to study structure formation in products such as bread and cakes during
baking. This service can be used to compare the effect of different ingredients and processes or to understand the origin of particular
structures or faults.
