Abstract: Gelatin is a protein derivative compound extracted from animal collagen through hydrolysis and drying process. An edible film can be made from three different types of constituent materials, namely hydrocolloids, lipids, and composites of both. An edible film is an edible thin layer, which is formed to coat food components, and placed on top of or between the food components. One type of colloid that can be used to make the edible film is gelatin. A plasticizer is a substance with low molecular weight, that can enter the protein-polymer matrix, so it increases the flexibility and forming capability of the film. Glycerol is included as a type of plasticizer, which has a low molecular weight, is hydrophilic, adding polarity, and is easily soluble in water.
