The degradation kinetics of vitamin C in three fruits |
|
namely; orange, banana and apple under different market |
|
storage conditions prevalent in Nigeria were |
|
investigated. Orange and banana samples were stored in |
|
sacks and open air at ambient conditions, while open air |
|
and refrigerator were used for apple samples. Storage was |
|
for 6 days duration. .Iodometric titration was used to |
|
determine vitamin C content of the fruits on a daily |
|
basis. Regression analysis was employed to fit the |
|
variations in vitamin C concentration in the different |
|
samples with time, to three kinetic models, to determine |
|
which model best describes the degradation trend. Results |
|
showed that vitamin C concentration in all the fruit |
|
samples reduced over time following zero order kinetics. |
|
Kinetic studies obtained the following degradation rate |
|
constants: orange 0.44g.L-1.s-1 and 0.29 g.L-1.s-1, for |
|
sack and open air storage respectively, banana 0.316 g.L- |
|
1.s-1 and 0.264 g.L-1.s-1, for sack and open air, and |
|
apple 0.122 g.L-1.s-1 and 0.188 g.L-1.s-1, for |
|
refrigerated and open air respectively. The study |
|
indicated that with respect to vitamin C retention, open |
|
air storage is preferable to sack for oranges and bananas |
|
while apples are preferably stored in refrigerator. |
