In this study, the influence of gelatinization degrees and high amylose starch concentrations on the quality of gelatin films was investigated. The presence of starch increased the thickness and transparency of the prepared films. It was found that hot water gelatinized starch improved the mechanical strength of gelatin films, especially at 50 wt.% concentration. The addition of high amylose starch, under all conditions studied, decreased film solubility and improved film integrity. This was particularly notable for films with gelatinized starch in hot alkaline media, in which much improved water resistance was observed. The addition of starch also led to increased thermal stability. The aforementioned variable influences can be attributed to a crosslinking process once starch was subjected to gelatinization and its consequent interactions with gelatin molecules. The findings in this study may serve as a platform to improve gelatin film performance and potentially extend applications of edible gelatin films in the food industry.
