Resumen de Nonfood Applications of Proteinaceous Renewable Materials

Justin R. Barone, Walter F. Schmidt

• It is well known that proteins are abundant in food and are vital to nutrition and biochemical function. What is not well known is that proteins derived from agricultural sources are used in everyday products such as glue and textiles. Research continues to find new uses for proteins in a wide variety of applications, most of which would be replacements for petroleum-derived materials. Proteins can be a viable source of polymers for fiber, molded plastics, films, and an array of products currently supplied by the synthetic polymers industry. The big advantages are that proteins are derived from a sustainable resource and can be processed in much the same way as conventional synthetic polymers. While there are many current and future nonfood uses for proteins, it is the intent of this review to concentrate on recent advances focusing on uses as polymers and biomaterials, which have enormous commercial potential.
