Abstract

The incorporation of silica (SiO2) into whey protein isolate (WPI)-based biocomposites film has been explored. This study aimed to determine the effect of SiO2 addition on the characteristics of WPI by casting. WPI was prepared with variations in SiO2 concentration ranging from 0% to 7% (w/w). The resulting biocomposite film was then studied for its mechanical, thermal, and morphological properties. According to the results, adding 7% SiO2 decreased the tensile strength by 13.82 MPa. In contrast, the elongation tendency increased by 50.57%. The increase in temperature indicates that the addition of SiO2 improves the thermal stability of WPI biocomposites. The WPI biocomposites have three temperature ranges: 38 to 50°C, 106 to 130°C, and 172 to 192°C. In addition, the incorporation of SiO2 causes the shape of the biocomposite to be granular, more heterogeneous and made of small particle aggregates. Overall, SiO2 has the potential to be used as a filler in biocomposites and in various food packaging applications due to its enhanced thermal characteristics.
