Determination of Ascorbic Acid Level in Bell Peppers

Abstract

The research work determined the vitamin C levels in green and red bell pepper fruits sold in Kontagora market. The analysis of vitamin C level was done by iodimetry titration method.  Vitamin C is required by human body to improve the immune system and can be obtained from the bell peppers. Bell pepper has different colours according to the level of maturity, ranging from green, yellow, orange, and red. Differences in colour also make possible differences in vitamin C content. The results show that vitamin C level in Red bell pepper juice contain more ascorbic acid (1.19mg/ml) than the Green bell pepper (0.33mg/ml), indicating that different stages of bell pepper maturity have different vitamin C levels. Therefore, this research recommends that based on the result and comparison with other literatures, further study should be carried out on the effect of heat on the ascorbic level in bell peppers, the amount of calories in bell peppers and also the amount of ascorbic acid level in yellow bell peppers
