Technical Abstract: Biopolymers, including starch and polysaccharides, have long been recognized and utilized for their ability to fulfill functional roles within food systems. Due to their demonstrated properties, renewable aspects, and biodegradable nature, biopolymers are becoming increasingly considered and utilized in place of petroleum-based polymers for industrial development of materials such as thermoplastics. Significant developments in research and technology continue to drive and facilitate the use of biopolymers in industrial applications. This session will provide an overview of the chemistry and processing required for conversion of starch and polysaccharides into biomaterials and thermoplastics. Chemical and structural consideration will include the physical chemistry of starch/biopolymer mixed systems, chemical modification of biopolymers for enhanced function, and the need for and role of plasticizers in biomaterial applications. From a processing perspective, a number of technologies are available to assist with conversion of starch and biopolymers into a wide range of products such as films, foams and thermoplastics. Processing schemes including reactive extrusion, injection molding, and film casting will be discussed in relation to their potential to produce various types of bioproducts. Finally, emerging trends and technologies in biopolymer chemistry and processing will be highlighted to provide a vision for biomaterial applications of the future.
