Abstract:
The review deals with analysis of ascorbic acid (vitamin C) content of some fruits i.e. mangoes,
oranges, lemons, apples and water melons sold in local markets in Uganda. Vitamin C content is
analyzed from various research works and compared. The methods for comparison were
spectrophotometric and titrimetric methods, the absorbance was measured spectrophotometricaly
at 521 nm. The titrimetric method is carried out by an iodometric back titration. The results from
this study showed that there is no much difference between the two methods but
spectrophotometric method is more preferred to determine the amount of vitamin C than
titrimetric method because it is easier to use and fast to produce results. Vitamin C
concentrations should be established such that people are informed about the type of fruit with
less health effects.
