Gelatin is a polypeptide produced from the hydrolysis of collagen. Gelatin can be made from fish skin, one of which is tilapia skin (Oreochromis niloticus). Gelatin is a hydrocolloid (protein) and is one of the components that can be used as material of edible films. Edible film is defined as a thin layer from edible material and is an alternative packaging that is biodegradable. In the making of edible films made from hydrocolloids, the quality of the film is often fragile, so it requires additional materials that function as plasticizers.
