Materials based on proteins from plant (wheat gluten,corn zein,and soy protein) and animals (gelatin,kelatin, casein,andwhey) are renewable and inherently biodegradable. Among them, gluten ptoteins present remarkable advantages since they are hightly available, have low cost, and can be obtained as by ptoduct from the wheat starch industry, which is steadily rising as starch is used for biothanol production, and in the manufacturing for other bioplastic such as thermoplastic strach(TPS) and poly (lactic acid)(PLA).However, gluten proteins have poor mechanical and water resistant properties making their modification essential to obtain suitable materials for diverse application. Their improvement can also lead to changes in their compostability, since their disintegration could be hampered or their biodegradation could be incomplete.
