Abstract

: Edible coating is biodegradable and eco-friendly packaging that current developments. Constituent components of edible coatings in the form of hydrocolloid (polysaccharides, proteins), lipids and composite. The edible coating serves as a protective material which is packed from outside influences also functions as a matrix of antimicrobial agents. Synthetic preservatives that many outstanding raises concerns of the community to use it, because of the high risk on health.
