Given the high selling price and its scarcity, some rural populations in Côte d'Ivoire consume the Phoenix reclinata date without knowing the functional properties for their well-being. The highlighting of the nutritional value of these fruits is necessary to promote its valorization and its consumption in the form of bioformulated foods. Thus, the physicochemical and antioxidant properties as well as the mineral richness contained in the pulps and the cores were determined using the Association&nbsp; of&nbsp; Official Analytical Chemists and &nbsp;spectrophotometric methods The analyzes were carried out on ripe fruits dried at 20°C in the laboratory of agrovalorization of the Department of Biochemistry and Microbiology, University Jean Lorougnon Guédé between March and May 2019. The results reveal that the pulps and the cores are weakly acidic with respectively pH values of 6.37 ± 0.13 and 5.74 ± 0.06. The pulps and the cores contain respectively dry matter contents (90.39 ± 0.14 against 92.1 ± 0.02), in fibers (10.40 ± 0.17 against 88.7 ± 0.48), in energy values ​​(335.2 ± 0.44 kcal against 378.7 ± 1.07 kcal), in total polyphenols (2.63 ± 0.19 against 3.69 ± 0.18) and in minerals. The pulp and the cores have, for 100 g of solids, sodium contents (3.22 ± 0.12 mg against 3.69 ± 0.18 mg), potassium (0.71 ± 0.07 mg against 2.52 ± 0.08 mg), in phosphorus (3.00 ± 0.02 mg against 2.52 ± 0.08 mg), in calcium (0.16 ± 0.04 mg against 0.65 ± 0.03 mg), zinc (3.30 ± 0.05 mg vs. 3.08 ± 0.03 mg), iron (3.09 ± 0.01 mg vs. 3.26 ± 0.01 mg) and copper (2.93 ± 0.06 mg vs 3.08 ± 0.03 mg). These nutritious potentialities could be recommended in the formulation of foods for the malnourished.</p> Blei Sika Hortense Digbeu Dogoré Yolande Niaba Koffi Pierre Valery Faulet Meuwiah Betty Beugre Avit Grah Maxwell Kouame Lucien Patrice ##submission.copyrightStatement## 2019-10-15 2019-10-15 1 8 10.9734/ajsspn/2019/v5i230059 Nutritional Quality Response of Carrot (Daucus carota) to Different Rates of Inorganic Fertilizer and Biochar http://journalajsspn.com/index.php/AJSSPN/article/view/30060 <p>Nutritional quality of most high valued crops including carrot can be influenced by soil management practices. A field study to evaluate soil management improvement effect on nutritional quality of carrot was carried out in two contrasting cropping seasons of two rainfall regimes ranging from 600 mm to 800 mm in 2016 and 2017 at Mampong in the Forest-Savannah transition zone of Ghana. Three rates of soil amendments using biochar rates of 0, 5 and 10 tons/ha and five rates of inorganic fertilizers (NPK 15:15:15 at 200 kg/ha; P&amp;K 50:50 at 50 kg/ha; P&amp;K 50:100 at 50 kg/ha; Liquid Fertilizer at 1 L: 200 L Water/ha; and the control were applied using 3x5 factorial in RCBD. The combined analysis for the different treatments showed that NPK at 200 kg/ha+10 ton/ha biochar gave the highest protein content while Liquid fertilizer+5 ton/ha biochar gave the highest beta-carotene and total carotenoid contents in carrot root during the minor cropping season of 2016. However, during the major copping season of 2017, a combination of liquid fertilizer +10 ton/ha biochar gave the highest protein content whilst NPK at 200 kg/ha +5 ton/ha biochar gave the highest carotenoid content for the carrot. Nutritional contents such as carbohydrate, beta-carotene and total carotenoids were boosted by soil amendments. This indicates that both biochar and inorganic fertilizers have varying effects on the nutritional qualities of carrot.</p> Kwaku Asante Joseph Manu-Aduening Margaret Esi Essilfie ##submission.copyrightStatement## 2019-10-16 2019-10-16 1 14 10.9734/ajsspn/2019/v5i230060
