Abstract
The present study was conducted to investigate effect of induced ripening agents on aroma profile, organic acids and sugars of Ambul banana ( Musa acuminata , AAB). Mature green bananas that are in same maturity stage were subjected to 1000 ppm ethephon and 1000 ppm acetylene and kept at 20°C, 80–85% RH for ripening. Aroma profile was analyzed by SPME-GC-MS, while organic acids and sugars were tested by HPLC. Naturally ripened banana was found to be more aromatic than acetylene- and ethephon-treated banana having highest number of volatile compounds (27) and high level of esters (65%). Malic acid, citric acid, and oxalic acids were significantly low in treated bananas compared to naturally ripened bananas. Glucose and fructose, which are major types of sugars in ripe banana flesh, were significantly low in acetylene-treated banana, while sucrose was not detected in both ethephon- and acetylene-treated samples at fully yellow stage. Although ethephon and acetylene trigger the ripening process, they lead to poor aroma profile and lower levels of organic acids and sugars in flesh of banana.
