摘要: The high oxygen barrier properties of whey protein based films and coatings means these materials are great interest to the food packaging industry. However, have poor mechanical such as tensile strength, Young's modulus elongation at break. Up until now, influence ultraviolet (UV) radiation on has not been reported in literature. This study thus investigates UV-radiation films. UV-irradiated showed increased strength a yellowing that was dependent time. After irradiation, no significant change properties, or In addition, solubility undertaken characterize quantify changes structure-property relationships. decrease buffer systems which break disulfide non-covalent bonds indicates additional molecular interactions arise with increasing dose. provides new data for researchers material developers tailor characteristics according their intended application processing.
