Chapter 23 - Proteins as Sources of Materials
Review articleOpen access

Publisher SummaryProteins are natural, renewable, and biodegradable polymers which have attracted considerable attention in recent years in terms of advances in genetic engineering, eco-friendly materials, and novel composite materials based on renewable sources. This chapter reviews the protein structures, their physicochemical properties, their modification and their application, with particular emphasis on soy protein, zein, wheat protein, and casein. First, it presents an overview of the structure, classification, hydration–dehydration, solubility, denaturation, and new concepts on proteins. Second, it concentrates on the physical and chemical properties of the four important kinds of proteins. Third, the potential applications of proteins, including films and sheets, adhesives, plastics, blends, and composites are discussed.
