“…7. Zein films are generally brittle and require the addition of plasticizer to improve their flexibility (Beck & Tomka, 1996;citebib11;Parris & Coffin, 1997;Santosa & Padua, 1999;Wu, Sakabe, & Isobe, 2005;Wu et al, 2003). Plasticizers are low molecular mass organic compound added to soften rigid polymers.…”

“…34 Loss of that water at high temperatures will destabilize the protein structure and cause a rearrangement. 35 Proteins from soy, 3 wheat, 6,8 sunflower, 9 -11 corn, 14,15,18 fish, 19 and milk 20 have been thermally processed into films using a variety of techniques but always with a low molecular weight plasticizer such as glycerol, polyethylene glycol, propylene glycol, or sorbitol. In this article, natural keratin from the fiber fraction of poultry feather was blended with various amounts of glycerol.…”

Keratin obtained from poultry feathers was modified with glycerol, which acted as a plasticizer. Films were prepared by pressing the modified keratin at temperatures concurrent with typical polymer processing temperatures. The films were completely cohesive as opposed to partially cohesive if pressed under the same conditions without glycerol. The films were "tough" and the mechanical properties show similarities to the properties of commercially available commodity thermoplastics. The keratin films were produced in a few minutes without reducing or oxidizing agents. The keratin films could have potential applications for which environmentally friendly materials are needed, such as food packaging or mulching films.

“…These functional groups can also be utilized for chemical modification to improve physical and mechanical properties. For example, Wu et al blended SP with polyurethane prepolymer based on polycaprolactone polyol/ hexamethylene diisocyanate (22); and the formation of urea-urethane linkages was detected in the cured resins, suggesting that the amino groups of SP were involved in the curing. The polyurethane prepolymer modified soy protein plastic demonstrated superior toughness and water resistance.…”

A novel approach was used in the preparation of soy protein concentrate (SPC) and biodegradable thermoplastic blends. In contrast to many other soy protein (SP) blends where SP functioned merely as a filler, in this study SPC was processed as a plastic in blending with poly(lactic acid) (PLA) and poly(butylene adipate-co-terephthalate) (PBAT), respectively. The plastication of SP and blending of the resulting SP plastic with PLA or PBAT were performed in the same extrusion process. The plastication involved gelation of SPC in the presence of water and subsequent plasticization of the gelated SPC by water and/or other plasticizer. The resulting PLA/SPC blends displayed a co-continuous phase structure and PBAT/SPC blends a percolated SPC network structure. Consequently, the blends demonstrated superior mechanical properties.
