Plant proteins are regarded as versatile, functional ingredients or as active biological compounds, and as essential nutrients in food. Besides food uses, plant proteins are also considered as "green" chemical molecules useful in manufacturing non-food industrial products. This new utilization of plant proteins presents a great challenge for agriculture and industry and will also be beneficial for the environment. In this book, numerous scientists working on all aspects of proteins from the major European crops report on the role played by plant proteins in food systems and their effects on human health. In addition, the most recent data on protein-based plastic materials and other non-food products are presented.
