Abstract

are the second most-produced vegetable around the world, behind the potato crop and one of the most important crops in West Africa. Tomato is a very popular crop which over time has been a major ingredient in human food all over the world, in Africa and especially in Nigerian dishes, they are rich in minerals, vitamins, essential amino acids, sugars and dietary fibers, tomato contains much vitamin B and C, iron and phosphorus. The objective of this study is to investigate the effect of shelf life of the popular Nigerian tomato varieties on vitamin, lycopene and sugar content. The experiment was carried in Babcock University, Ilishan-Remo Ogun State, Nigeria. There were nine (9) different varieties of tomatoes selected for this study: Roma VF, U C 82-B, Rio Grande, TROPIMECH, Roma Savanah, Rio Fuego, Hausa Local (which are regulars in Nigerian markets), Beefsteak and Yellow Pear. Experiments were carried out to determine: Lycopene, Vitamin C, ?-Carotene, Vitamin B3 and Sugar Content and the variation across shelf life. The varieties maintained a good texture and wholesomeness as at day 7; however, there was reduction in the texture and wholesomeness at day 14 with UC 82-B (<2>
