Fish consumption has steadily increased during the last few decades, accompanied by an increase in aquaculture production at the expense of wild capture. In line with this trend, the preferences of an increasingly wealthier and urbanised population are turning towards convenience foods, driving the fish industry to transition away from marketing whole fish and towards filleted products. Gelatin is created by partially denaturing collagen, the primary structural protein in connective tissue, resulting in a more soluble material with a larger range of applications. Gelatin properties vary based on animal species, age, source tissue, and extraction circumstances. In fish, the skin yields more and higher- quality gelatin than the bone.
Fish skin waste can be widely used for biopolymer extraction.Gelatin extraction using saline and alkaline solutions. FTIR was also used to examine the chemical structure and thermal degradation. The current study focuses on the extraction and characterisation of gelatin from fish skin, as well as the preparation of a gelatin/PVA/ZnO based biodegradable blend film prepared solvent casting method. The effect of several parameters, such as mechanical, thermal, optical, and morphological qualities, on different blend film compositions was investigated. Differential scanning calorimetric and scanning electron microscope examinations of gelatin/PVA/ZnO blend films revealed miscibility, interaction, and micro phase separation of chitosan, PVA, and ZnO molecules. The created mix film can be used for biodegradable packaging.
