N2 - A sensor system utilising optical fibre sensing techniques is reported, which has been applied to the food industry in order to control the cooking process in a large-scale industrial oven. By monitoring a wide variety of products as they are cooked in the oven it has been possible to classify their cooking stage. This paper examines the application of principal component analysis, using karhunen loeve decomposition, to the spectral data from the sensor prior to application of pattern recognition through the use of an artificial neural network. Investigations have been carried out to ascertain trends in various products in order to design a general colour scale, which can classify several products using a single neural network. The food types discussed in this paper are steamed skinless chicken fillets, roast whole chickens, marinated chicken wings, sausages, pastry, breadcrumb coating and char-grilled chicken fillets.
