Mechanical, Optical, and Microbiological Characteristics of Biocomposite Edible Film Based on Canna Starch and Nanochitosane with the Addition of Fish Oil: A Review

Edible film is a packaging development for environmentally friendly food that is composed of organic ingredients, so it is safe for consumption. Natural polymers that make up edible films include polysaccharides, lipids, and proteins to replace synthetic packaging materials. The characteristics of good edible film have properties like other plastic packaging, namely being easy to shape, transparent, flexible, not easily damaged, and cheap. Canna starch has the potential to be used as a building material because it contains high levels of amylose and amylopectin, and nanochitosan has good antimicrobial activity. The addition of fish oil to edible films is a solution to correct the deficiencies of edible film biocomposites, which can increase their hydrophobic properties and tensile strength.
