Abstract: Cucumber (Cucumissativus) is a creeping vine that bears cylindrical fruits. It belongs tothe gourd family cucurbitacea. It is popularly consumed in all parts of Nigeria.The comparative assessment of proximate, mineral composition and mineral safetyindex (MSI) of cucumber (peel, pulp and seeds) was determined using standard analytical methods(Association of Official Analytical Chemists) for proximate, mineralscomposition and mineral safety index. Results showed protein content of (15.9 - 26.5) g 100 g, Carbohydrates (33.7 -52.7) g 100 g, crude fat (0.13 - 1.44) g 100 g, moisture (12.3 - 21.7) g 100 g and ash (7.85 - 11.6) g 100 g respectively. The calorific values were 1077, 1171 and 1296 kJ 100 g for peel, pulp and seed respectively.Considerable levels of essential and trace elements were observed in thesamples. The Na K ratio (0.25 - 0.36) was close to 0.6, whichdoes not promote high blood pressure in man. The Ca Mg values obtained wereless than the recommended value of 1.0. The milliequivalent ratios of [K (Ca + Mg)] (3.91 - 4.48) were comparably higherthan the recommended value of 2.2 which means the sample would promote hypomagnesaemia in man. The mineral safetyindexes of Fe, Na, Ca, Zn, Cu and Mg of the samples (peel,pulp and seeds) indicate no overloadingin the body if consumed. The results showed that all the parts of Cucumis sativus are good potentials of nutrients for humanconsumption.
