This research was designed to compare two methods for determination of vitamin C (Ascorbic
acid) content in Annona squamosa peel and pulp as well as in Velvet tamarind pulp. Vitamin C
content of fresh fruit parts were determined by titrimetric and spectrophotometric methods using
potassium permanganate as chromogenic reagent. Absorbance was measured
spectrophotometrically at 530nm. The titration method was carried out using iodometric backtitration.
The results obtained from the study revealed that there was significant difference
between the two methods and the higher vitamin C content was recorded in Annona squamosa.
Both samples could therefore be used to supplement vitamin C daily intake requirements.
