**2.5 Gelatin-based coatings and films**

Gelatin is a hydrophobic protein usually found in wheat which is also a globular protein and also used in some edible coatings/films due to its low cost and availability. Gelatin coatings usually depict good transparency, mechanical and barrier properties and can be manufactured via an extrusion or casting process. The nature of the gluten has significant impact on its filming properties.
