Three hundred and twenty (320) oranges of Valencia variety
were stored under cold conditions in the refrigerator for 8
weeks. The following parameters were carried out during the
course of storage: Total soluble solids, titratable acidity,
weight loss, firmness, pH, vitamin C and sugar/ acid ratio.
The final value for firmness for coated oranges was found to
be 1781.25 + 118.30N, while that of uncoated oranges was
1531.25 + 185.53N. The pH was gradually increasing during
the course of storage in the two treatments, whereas vitamin
C was found to be decreasing in storage. The total soluble
solid for coated oranges was 9.79+ 1.14% while that of
uncoated oranges was found to be 9.34 + 0.06% at the end of
storage. There was a linear decrease in titratable acidity
during the course of storage. It was found that the value
obtained for coated oranges was higher than that of uncoated
oranges which was obtained to be 1.14 + 0.07 at the end of
storage. Converse to this was obtained for % weight losses
in the two treatments. The weight loss for coated oranges
was 29.20+ 0.55%, while that of uncoated oranges was 53.30+
1.17% at the end of storage. A linear increase was observed
in sugar/acid ratio in the two treatments during the course
of storage with higher value being recorded for uncoated
oranges as 8.90 + 0.87, while lower value was gotten for
coated oranges as 7.43+ 0.34%.
