Seaweeds: New Source of Packaging Edibles

Abstract

Biopolymers are playing a pivotal role in recent arenas, especially in addressing the environmental concerns caused due to biostable polymers. Edible films and coatings especially from marine macroalgae (seaweed) have gained popularity in food packaging and as active carriers of ingredients. Seaweed-based biopolymers like agar, carrageenan and algae have varied applications in the food industry including gelation, emulsification, water-holding capacity, etc. Traditionally, seaweeds have been used as sushi wrappings, condiments, vegetables, etc. They are present in abundance, economic and are sustainable. Recent research supports the role of edible seaweeds as antioxidants. Seaweeds have found an important niche of application in food packaging.
