Result: Tech. Option I and II shows better result with BCR 2.26 and other attributes like good taste, more shelf life at RT, Natural smell and firmness. However, ripening period was short and colour was found uniform in FP. It was found that banana ripened with carbide get detached from hand after ripening but remain attached in case of ripened with ethrel. In case of Tech. Option III, it was found that ripening starts from upper hand i.e nearer to etharel coating and later goes on lower side and takes 4-8 days in ripening. This provides opportunity to small sellers that they sell upper side ripened banana and provide more time.
