Banana fruit is a really chilling injury sensitive horticultural product. Its sensitivity to cold temperatures generates a serious practical, economical and commercial problem.
Chilling injury related physiological responses of Cavendish type mature green banana samples stored at 2.5, 5, 10 °C and near optimal (15°C) cold storage temperature were investigated by
- non-destructive optical methods (surface color and chlorophyll fluorescence measurement, DA-index® evaluation)
- and by the determination of the physiological reactions (respiration, ethylene production, symptom manifestation) either during cold storage or during the 8 days long subsequent shelf-life.
The well-known positive effects of low temperature storage were proven on mass loss, respiration and ethylene production.
In case of bananas stored at 2,5-10 °C, the chilling injury related changes in chlorophyll content related DAindex® and IR-values; Fm and Fv chlorophyll fluorescence values together with the L*, a*, b*, C* and hue angle surface color characteristics suggested clearly from day 3 the onset of chilling injury phenomena several days before the visible signs of chilling injury appeared.
