Food waste or food loss is food that is discarded or lost uneaten. The work presented in this paper is related to our researches in the field of pervasive and ubiquitous computing. Our "Pervasive Fridge" prototype allows users to be notified proactively, when a food arrives to its expiration date. Speech and image recognition are also integrated in our prototype. This system combines various resources in order to scan barcode, identify and store data related to products, with a smartphone. Later, notifications are sent freely to consumers by mail, SMS (with no charge) and pop-up, to avoid uneaten food loss.
