ABSTRACT
PROTEINS have been widely studied as film-forming materials due to theirrelative abundance, film-forming ability, and nutritional qualities. Prevalent types of plant and animal protein film-formers have been discussed in other chapters. Nevertheless, these are not the only film-forming proteins available. Other proteins, which are of limited availability, may be of interest due to a unique property they provide to films or an advantage they provide to film formation. Limited availability may be due to relatively low production of the protein source or limitations in recovering the protein as a co-product from a process.
