An increased interest has been shown in the use of biopolymers as material for food packaging, and NMR was employed to study the physicochemical properties of plasticized com zein films.103 The elucidation of freezing effects in foodstuffs was approached by studying the interactions between amino acids, sugars, and alcohols at temperatures below 273 K.104...

Until recently, the ordy uses and apphcations for proteins were in food sciences [55]. The development of studies on non-food uses of agricultiual raw materials initiated an interest in protein-based plastics. A number of proteins of plant origin have received attention for the production of biodegradable polymers. These proteins are com zein, wheat gluten, soy protein, and sunflower protein. 

Proteins are mostly hydrophilic, being very sensitive to humidity and highly soluble in water which constitutes an important limitation to their use in food packaging applications. However, some of them such as com zein, soy, or whey proteins extracted from the by-products of food industry have desirable properties as biodegradabihty and barrier power to oxygen for food packaging. In particular, com zein is obtained...

Various kinds of proteins have been used to produce bio-based polymers. Some of the examples include soy protein, com zein (CZ), and wheat gluten. In this section, we will restrict the discussion to a brief description and additional material can be obtained from the cited hterature. 

A wide range of animal and vegetable protein sources, such as milk casein, egg white, chicken feathers, fish albumen, collagen, gelatin, hair, hooves, horn, soy beans, com zein, peanuts, sunflower seeds, hemp seeds, castor oil seeds, were explored as the protein sources for manufactured protein fibers. Many produetion methods also were developed for converting these proteins into fibers, and most of them at least involved fom steps separation of protein, solnbiUzation of protein, fiber spinning, and insolubilization of protein.
