It was reported that the sweet cherry TA content had a negative correlation with respiration rate during cold storage and low O2 and high CO2 retarded respiration rate and TA loss (Harb et al., 2003). In contrast, MAP1 did not slow the
respiration rate and TA reduction, therefore, had no effect on flavor loss.
The inferior flavor in MAP3 was due to a fermentative offflavor, which is related to a significant accumulation of ethanol.
‘Skeena’ synthesized a higher content of ethanol in MAP3 and developed more intensive fermentative off-flavor than ‘Lapins’. A significant increase in ethanol concentration in fruit during storage indicates the occurrence of anaerobic respiration
