    PROXIMATE COMPOSITION OF RIND AND SEED OF WATERMELON (
    (Department of Chemistry, Nasarawa State University, Keffi, 2020-07-11) Abdulazeez, A.; Abdullahi, U.; Audu, Saratu Stephen; Ibrahim, I.L.; Kwoku, S.I.; Gimba, A.; Umar, M.T.; Babatunde, J.; Uthman, A.
    Citrullus lanatus belongs to the Cucurbitaceae family and consists offour species are C. locynthis, C. ecirrhosus, C. lanatus and C. rehmii. Water melon plant is a trailing hairy annualplant with rough angular stems and dark green alternate leaves carried on fairly long petioles. Water are monoecious and unisexual with pale yellowflowers. The fruit is large and round or oblong with a hard-smooth rind with a size normally rangingfrom 1.5 to 15 kg. Citrullus lanatus have found to rich in vitamin, antioxidant and minerals. Therefore the aim ofthis work is to determine Proximate Composition ofthe rind and seed of watermelon Citrullus lanatus l. foursamples ofCitrullus lanatus were collected, identified as Ibrahim Badamasi Babangida University, Lapai,farm, Cecce, Ibrahim Badamasi Babangida University main gate and Gidan gwarifarm then were washed with distilled water to remove sandparticles, followed by slicing to separate the rind using a clean knife. The rind will be chopped into liny cubes. The seeds will be carefully removedfrom the pulp and washed. The rind was sun driedfor two daysfollowed by oven drying at 50°Cfor 24 hours. The dried samples will be ground using ceramic pestle and mortar. Finally, the powdered sample was usedfor all the analysis other than moisture in whichfresh sample was used. The valuesfor ash contents of the proximate constituent ofseed and rind of watermelon were found in (cecce, IBBUL, IBBL main gate and Gidan gwari) farm ranged between 6.60±0.03, 5.10±0.06, 5.00±0.10 and 4.90±0.00 while rind are 0.25±0.02, 0.25±0.11, 0.20±0.06 and 0.30±0.01, moisture, crudefibre, crudefat, crude protein and carbohydrate ranged between 10.40±0.05, ll-00±0.04, 10.82±0.04 and 11-00±0.01 while 93.66±0.01, 94..00±0.00, 94.00±0.03 and 92.80±0.06, 42.80±0.01, 45.00±0.03, 44.30±012 and 43.00±0.13 while 0.21±0.00, 0.30±0.05, 0.23±0.02 and 0.26±0.02, 14.40±0.02, 13.90±0.05, 14.12±0.05 and 14.10±0.11 while 0.13±0.03, 0.10±0.02, 0.13±0.02 and 0.15±0.00, 7.70±0-04, 8.00±0.01, 7.08±0.07 and 7.50±0.03 while 0.55±0.01, 0.60±0.03, 0.58±0.00 and 0.80±0.02 and J8.10±0.01, 17.00±0.01, 18.70±0.11 and 19.50±0.03 while 5.22±0.02, 5.50±0.05, 5.86±0.01 and 5-69±0,02. The Citrullus lanatus contains nutrients and mineral elements that are essential for life. These Citrullus lanatus rind may provide considerable medicinal, health and economic benefits if freshly consumed or utilized in food products and also supplementing human nutrition requirements for normal growth and adequate protection against defects associated to the malnutrition.
