Nutritional and Anti-nutritional Content of Citrullus Lanatus whole Fruit and Pulp

Background: There is little awareness on the nutritive value of the whole Citrulus lanatus fruit, as the pulp is mostly consumed while the other parts are discarded as waste. This study evaluated the nutritional components of whole fruit and pulp of Citrulus lanatus. Methods: Proximate, anti-nutrient, phytochemical, mineral, and vitamin compositions were determined using standard methods and the results obtained were compared. Results: The result revealed that the crude protein, crude fibre, and crude lipid contents of the whole fruit were significantly (p<0.05) higher than those of the pulp while the carbohydrate content was significantly (p<0.05) higher in the pulp. The anti-nutrient and phytochemical result showed that tannin, phytate and alkaloid of the whole fruit were significantly (p<0.05) higher than those of the pulp while no significant (p>0.05) difference was observed in the oxalate and alkaloids contents. The magnesium and iron content of the whole fruit was also significantly (p<0.05) higher than those of the pulp, however, there was no significant (p>0.05) difference in the zinc content of both samples. The phytate to iron, and zinc ratios showed tha
