Abstract
The length of the green-life period is an important parameter in the export of Cavendish bananas. Conventional methods in determining green-life are still relatively difficult to be standardized because they are subjective. The initial phase shift from green to yellowish-green as the end of green-life is very difficult to detect and quantify with naked eyes. Therefore, we need a standard method that can be used to determine its green-life. The purpose of this study was to test a new method for determining the green-life based on image processing data of Cavendish bananas after receiving postharvest treatments. The data were collected from Cavendish bananas at various maturity levels which had received postharvest treatments of fruit coatings and storage temperatures. The results showed that intensity of red (I-Red) increased, while intensity of green (I-Green) decreased until the end of observation. Green life was ended when I-Red showed a greater value than I-Green. According to the method, Cavendish bananas in cold temperature storage showed a longer green life than room temperature storage with average of 26.33 days and the longest was 35 days. Meanwhile, storage at room temperature showed average green life length of 14.25 days with the longest period was 16 days.
