Abstract:

The need to quantify the ascorbic acid contents of five selected fruits using iodometric and UV-spectrophotometer methods necessitated the research work as vitamin C belong to the class of essential nutrients required for body physiological developments. The ascorbic acid contents of the five selected fruits were evaluated using standard procedures for evaluating iodometric method and the UV spectrophotometer. The results of the analysis using iodometric method indicated that the Citrus limon had (34.53±0.08c mg/100g), Vitis vinifera (15.35±0.01bmg/100g), Malus pumila (11.51±0.07a mg/100g), Citrullus lanatus (11.51+0.01a mg/100g) and Ananas comosus 11.51±0.05a mg/100g). The UV spectrophotometer method indicated the values as Malus pumila (19.19±0.48c mg/ml), Citrus limon (18.09 ±0.29c mg/ml), Ananas comosus (9.57+0.53b mg/ml), Vitis vinifera (9.17±0.21b mg/ml), and Citrullus lanatus (4.20±0.07c mg/ml). The values obtained using iodometric methods fall into the range of recommended dietary allowance (RDA) of 46 mg/100 g. The results had shown that the fruits were rich in ascorbic acid and can adequately cater for any deficiency that may arise from lack of vitamin C.
