Pengaruh Pelapisan Kitosan terhadap Daya Simpan Buah Pisang Ambon

Abstract

The banana needs post harvest treatment to be not decay quickly. One of the way is by coating. Chitosan is a substance that can be used to coat the fruit, which is a polysaccharide derived from shrimp and crab shell waste. The aims of the research was to study the effect of chitosan coating on post harvest of bananas, and find out the optimal concentration of chitosan as a natural coating materials. This research used the completely randomized design (CRD) method with one factor. The factor was the chitosan coating by three level treatments with different concentrations. First concentration was 0%, second was 1%, and the last was 2% w/v. Each treatment was repeated four times. The results showed that treatment with concentration of chitosan couldn’t inhibit loss of. There is no consistent effect of chitosan on acid titration, vitamine C content and no significant effect on total soluable solute. From organoleptic test that was conducted in 12 day after treatment indicated that respondent still like bananas on 2% concentration of chitosan treatment.
