Abstract
The fruits of Msasa and Jaffa orange varieties were harvested
and subjected to post-harvest treatments namely; dipping in
hexanal, dipping in calcium chloride and compared with
untreated control; and they were stored at ambient (28 ± 2°
C) and reduced temperatures (18 ± 2°C) conditions. Data were
collected on the 0, 4 th , 8 th , and 12 th days from the date of fruit
harvest. Chemical analyses were conducted to determine vita-
min C content, total sugars, reducing sugars and total flavo-
noids. Post-harvest treatments had a significant effect on
vitamin C and total flavonoids of Jaffa orange fruit. Hexanal
treated fruit had higher values of total flavonoids, vitamin C,
and total sugars compared to calcium chloride treated and
control fruit. The storage durations showed significant effects
on the vitamin C content of Jaffa, total flavonoids, the total and
reducing sugars of both fruit varieties. Vitamin C and total
flavonoids decreased with increasing storage duration of fruit.
The significant interactions of factors were observed on total
sugar which was increasing with increasing storage duration,
but higher in hexanal treated and ambient stored fruit. Based
on consumer acceptance test, the hexanal treated fruits were
the most liked followed by calcium chloride treated and
untreated fruits based on the appearance, taste, texture and
overall acceptability.
