Abstract

This research was aimed at investigating the concentration of Ascorbic Acid (Vitamin C) in some commercial fruits juices: ‘5’ Alive, Hollandia yoghurt, Nutri milk, Ribena, Lacasera, Happy hour, Viju milk, Chi exotic and Chi vita sold in Ugbokolo, Benue State, Nigeria by titrimetric method using 2,6-dichlorophenolindophenol (DCPIP) as titrant. The ascorbic acid (AA) content in milligram per 100ml of the various juices investigated is in the order: ‘5’ Alive (11.25) > Ribena (5.47) > nutri milk (5.31) > Happy hour (4.38) > Hollandia yoghurt (1.25) > Lacasera (0.47) ≈ Chi exotic (0.47) >Viju milk (0.31) > Chi vita (0.16). It was observed that half a litre of ‘5’ Alive (56.25 mg AA) a day is suitable for adults and pregnant women, a litre each of Ribena (54.70 mg AA) and Nutri milk (53.10 mg AA) per day for adults, while a litre of Happy hour (43.80 mg AA) per day is suitable for adolescents. It can be concluded that commercial fruits juices when taken in large amount will add to the daily human dietary intake of the vitamin.
