An intelligent optical fibre based sensor system for monitoring food quality

It is evident that colour analysis of food is critical in the sale of pre-cooked foods. Through the use of spectroscopy, in the region of the visible and near infra-red spectrum, it is possible to examine different colours and then analyse them. Combining this with Artificial Neural Networks (ANNs), a pattern recognition system is generated to classify between colours that are favourable and those that are not optimum, in an effort to control the cooking process.
