Abstract
Abstract Experiments were conducted at the Sokoine University of Agriculture to assess the effects of hexanal at (0.02%)
(volume/volume) and calcium chloride (2%) (weight/volume), on post-harvest quality of mango (‘Palmer’ and ‘Apple’)
under different storage conditions and durations. A three factors factorial experiment was used for each variety and
replicated six times. The fruits were stored at ambient temperature (28 ± 2 °C) or reduced temperatures (18 ± 2 °C)
storage conditions. Data included physiological weight loss (PWL), fruit firmness, total soluble solids (TSS), titrat-
able acidity (TA), TSS/TA ratio, vitamin C, total flavonoids, reducing sugar and total sugars which was collected at 0, 4, 8
and 12 days after harvest. Results indicated that hexanal and calcium chloride significantly (p \ 0.001) reduced mango
PWL and improved fruit firmness and TSS of both varieties compared to untreated fruits. Hexanal-treated fruits maintained
high vitamin C, total flavonoids, total and reducing sugars irrespective of the storage conditions. Vitamin C and total
flavonoids of mango fruits decreased with storage time, whereas total and reducing sugar contents increased with storage
time. Both treatments maintained physico-chemical qualities of mango fruits, when stored under reduced temperature
storage.
