Abstract : Over the past few years, electronic nose technology is offering a non-destructive method to sense aroma, which can be used to determine fruit ripening stages after harvesting. The objective of this study was to monitor mango fruit ripening after harvest using electronic nose (zNoseTM). Data acquisition was started using an electronic nose for a total of one hundred locally grown mangoes cv. Chokanan. The fruits were divided into two different groups, unripe and ripe mangoes. Concentration of volatiles was measured using electronic nose for each of the two groups during storage. However, to be able to classify the mangoes into three classes, namely unripe, ripening and ripe, the experiment was carried out with the unripe samples for three more days, every 48 hrs from the starting day. Besides, observation of new volatiles from the unripe mangoes as they were ripening indicated trend of volatiles during mango ripening, proving the efficacy of electronic nose for the formation of climacteric crops profiles in terms of volatiles liberated during ripening.
