Agricultural Value Added, Food and Nutrition Security in West Africa: Realizing the SDG 2

This study examined how food security will be achieved in ECOWAS through agricultural value added. The study made use of panel data sourced from the World Bank World Development Indicators (WDI) and the Food and Agricultural Organisation (FAO) databases; it employed the fixed effects econometric technique. Results from the analysis showed that 1% increase in agricultural production, agriculture employment, agricultural valued added, political stability and absence of violence as well as access to electricity all things being equal, will bring about 14.2, 56.9, 1.9, 1.5 and 42.5% increase in food security. Thus, the study recommended that the governments of the West African countries should ensure that there is adequate security in the economies so as to encourage people to practice agriculture

The Antioxidant Property of Aframomum danelli Spice in Oils.

A study was carried out on the antioxidant property of Aframomum danelli extract in palm oil and soybean oil. The activity of A. danielli extract was compared with those of other antioxidants of other plant sources, rosemary extract and d- tocopherol, at different concentrations. A. danielli was as active as rosemary plant extract in reducing rate of peroxide formation in soybean oil at concentrations of 200 ppm and 300 ppm . A danielli was much more effective than tocopherol in reducing peroxidation in soybean oil and palm oil at the higher concentrations except at 50 ppm.

Physico-chemical Properties of Pure Water Samples in South Western Nigeria

Pure water samples were evaluated for their physicochemical properties. Samples 5 gave higher values of K(15 ppm), mg(6.75 ppm) and Zn (0.04 ppm). While sample 6 was high in P (4.85 ppm). The pH value of samples 8 (7.65) was also higher. Biochemical Oxygen Demand (B.O.D), Chemical Oxygen Demand (COD) and Total Suspended Matter were not detected in all the samples. However the total dissolved solids of sample 3 (0.012%) was very low. The colour of samples 1, 2, 4, 5, 7 and 8 are not significantly different from each other, while samples 3 and 6 are significantly different from each other. The taste of samples 2 and 5 were objectionable while the odours of samples (2-8) were objectionable. It is apparent from this study that the quality of the pure water samples could improve if a better water treatment is adopted.

The activity of A. danielli extract was compared with those of other antioxidants of other plant sources, rosemary extract and d-tocopherol, at different concentrations. A. danielli was as active as rosemary plant extract in reducing rate of peroxide tbrmation in soybean oil at concentrations of 2OOppm and 3OOppm . A danielli was much more effective than tocopherol in reducing peroxidation in soybean oil and palm oil at the higher concentrations except at 50 ppm

Physiochemical and antioxidant properties of roselle‐mango juice blends; effects of packaging material, storage temperature and time

A study was conducted to determine the effects of packaging materials, seasonality, storage temperature and time on physiochemical and antioxidant properties of roselle-mango juice blends. Roselle extract (20%, 40%, 60%, and 80%) was mixed with mango juice and stored in glass and plastic bottles at 4°C and 28°C. Total soluble solids, pH, titratable acidity, reducing sugar, color, vitamin C, total monomeric anthocyanins, total phenols, and antioxidant activity (FRAP) were evaluated in freshly prepared juice, and after, 2, 4, and 6 months of storage. The results showed that total soluble solids, reducing sugars, and pH increased with storage times under different storage time, irrespective of packaging materials. The acidity, color, total monomeric anthocyanin, vitamin C, total phenols, and antioxidant activity decreased during storage irrespective of storage temperature and packaging material. Loss of anthocyanins, total phenols, and vitamin C content were higher in blends stored at 28°C than 4°C
