Karakteristik Edible Film dari Pektin Hasil Ekstraksi Kulit Pisang

Banana peel is a waste of banana processing industries which is obviously uneconomy and unfriendly to the environment. However, this material could be used as a source of important natural compounds, such as pectin. Owing to the fact that pectin has good gelling properties, it can be used to make edible film. The objectives of this research were to extract and characterize pectin from banana peel and to make edible film from the obtained pectin by using glycerol as plasticizer. Characterization of edible films were conducted in terms of color, thickness, elongation, tensile strength and water vapor transmission. The research used factorial completely randomized design. The results showed that yield of pectin made from ambon banana peel ripeness level one was 8.42% with the characteristics werewater content : 11.27% (<12%), ash content : 1.70%, low methoxil content : 4.15% (
