Biodegradation of edible film from corn starch and iota carrageenan with butterfly pea flower extract (Clitoria ternatea L)

Abstract

Food packaging with natural ingredients is widely developed. Edible film is food packaging made of natural materials. Plastics made from natural materials can degrade rapidly. The purpose of this study is to analyze the biodegradability of natural films. Corn starch (CS) and iota carrageenan (ICarr) were combined with butterfly pea flower extract (BE) as edible film materials. The method of preparing the edible film was bench casting. The edible film was analyzed for morphology by SEM and biodegradation analysis. The SEM results of CS/ICarr/BE edible film showed compact morphology. The CS/ICarr edible film obtained 0.052 g.day-1 and degraded with seawater faster than the one with soil, which obtained 0.042 g.day-1.
