Colour and visual appearance of food

Consistent and accurate measurements of the colour and visual appearance of food products is extremely important. Various methods are available for colour measurement, allowing a wide variety of sample types to be measured. Colour measurement results are typically provided on the CIELAB scale. Others are available on request.


Chromameter
This hand-held instrument provides quantitative colour measurements and is robust enough to be operated in production environments. Ideal for use during NPD or reformulation trials.


Spectrophotometer
This is a laboratory based instrument that provides very accurate quantitative colour measurements, calculated from measurements of the full spectrum. Two measurement modes are available, depending on the nature of the sample. Uniform solid materials and powders are measured in reflectance mode. Transparent liquids are measured in transmittance mode. Ideal for uniform solid materials, powders and transparent liquid products.


DigiEye
DigiEye is an imaging system that captures colour calibrated images. Colour measurements of specific regions within a non-uniform product can be made. This instrument is ideal for quantifying colour variation across a product (e.g. extent of browning on a baked product). Additionally, this instrument can be used to produce high quality images for reliable documentation of appearance, including colour calibrated printed images for use as specification control charts.


Standard colour methods are available for specific products, including:
