Banana (Musa acuminata Coll. Cavendish cv. Williams) eating quality was assessed through winter, spring and summer, and for mildly chilled bananas with symptoms mimicking that of ‘winter-chilled’ fruit using sensory testing and principal component analysis of mass-spectrometric data obtained from a ‘chemical nose’. Sensory testing of bananas harvested at different times of the year showed no differences in flavour preference, even though soluble solids were higher in spring at 23.6%, compared with winter at 22.6% and summer at 21.9%. Principal component analysis of mass-spectrometric data did not reveal aroma differences between times of the year. Results of difference tests for mildly chilled and non-chilled bananas indicated no differences in aroma intensity or sweetness. Mild chilling did not alter soluble solids and principal component analysis of mass-spectrometric data did not discriminate between chilled and non-chilled bananas.
