Assessing the structure and interaction of sustainable Bio – Composite Films Prepared form deamidated Rice Bran Protein

Rezumat

Rice bran protein (RBP) was utilized to prepare bio-composite films after deamidation modification process with deferent percentages. The physical, mechanical properties, exposure to light properties, FT-IR analysis, surface shape by SEM, thermal stability by DSC and X-ray diffraction were applied to study the potential interaction, structure and stabilizing the thermal property of the prepared films. The deamidation process has proven successfully, depending on the cleared changes of shapes of FTIR curves resulting from RBP compared with deamidated rice bran protein (DRBP). The deamidation
process enhanced tensile strength, elongation at break, haze, transparency, gloss and opacity properties of produced films from DRBP. Additionally, the produces films from DRBP presented smooth and homogenous surface with increasement of thickness, solubility and decrement of water vapor permeability and cristallinity compared with films from RBP.
