Abstract: This study aimed to find out the effects of supplementation of wheat bread with food industry by-products, orange peels, at 5%. 7.55 and 10% levels. The results show that orange peels contained: 1.41%, 2.1%, 3.33%, 6.78% and 86.38% protein, lipids, fiber, ash and carbohydrates, respectively. The rheological analysis showed that maximum resistance to extension was found to be increasing from 420 in wheat flour to 531 mm in wheat flour containing 5% orange peels powder, while increasing the addition of orange peels to 7.5% and 10% caused an increase in dough resistance to extension to 660 and 798 B.U, respectively. The results also indicated that addition of orange peels to wheat flour caused an increase in arrived time and a decrease in dough stability. The bread samples prepared by adding orange peels have lead to increase in the water absorption while the arrival time and dough stability were decreased. So fiber as a food industry by product is recommended to be used as food additives to gain nutritional and healthy benefit.

Abstract: The use of brewery spent grains in the cultivation of some fungal isolates was investigated. Five fungal isolates namely: Rhizopus stolonifer, Rhizopus oligosporus, Mucor racemosus, Aspergillus niger and Mucor rouxii were selected. The growth and performance of these micro organisms were observed on substrate formulated from spent grains, while commercial yeast extract was used as a control of the experiment. Dry biomass were obtained were obtained using standard procedures and pellet sizes were determined by diameter measurement. The isolates showed best growth on substrate containing spent grains and commercial yeast powder. Aspergillus niger showed the highest extension growth of 380mm at 144hrs in 0.9% w/ v of spent grains and yeast powder combination in the ratio 1: 1. The biomass production by each micro organisms peaked at the 90th hour.

Abstract: A reproducible and robust enzymatic desulfation reaction utilizing Sulfatase enzyme from Helix pomatia type H1, was developed and used in conjunction with an optimized HPLC-UV/ESI-MS/MS method developed in this study, for complete separation and identification of desulfated glucosinolates, extracted from 89 AGDH mapping population derived from a cross between rapid cycling Brassica oleracea lines; A12DH and GD33DH with high resolution for quantification measurements were used. In addition, we have demonstrated the first use of two internal standards during the preparation of the plant material for analysis, which significantly improved the reproducibility of the quantitative measurements. The quantitative data were then used for the identification of significant Quantitative Trait Loci (QTL) for individual glucosi-nolates and for key points in their biosynthesis, revealed for the presence of major gene effect near the top of B. oleracea linkage group 9 (LG9), associated with aliphatic glucosinolate synthesis. Moreover, a number of novel QTLs were also identified, which control the synthesis of glucosinolates.

Socio-Economic Manifestations of Hidden Hunger in Schoolchildren in Sub-Saharanafrica

Abstract: Hidden hunger or micronutrient deficiency continues to bedevil developing economies in Sub-Saharan Africa. Cumulatively, efforts to alleviate micronutrient deficiency have not been as great as those directed towards protein-energy malnutrition and altogether less on the important age group, the school age children. There is lack of clear understanding of the relationships between hidden hunger and the more obvious socioeconomic conditions. Good education is regarded as the window of opportunity to break the vicious cycle of poverty. Poverty eradication programmes have often been contextually delinked from nutrition interventions and education provision and as a result, nutrition interventions have focused much less on the school child.For all intentions, nutritional interventions targeted at pregnancy, infancy and early childhood, as is the status quo, are all proactive approaches intended to produce better outcomes in the long term. Perhaps it is important to have a holistic approach that includes school children in nutritional interventions in sub-Saharan Africa. This study therefore sought to uncover the problem of hidden hunger among school children and illuminate on the linkages between this problem, educational achievement and the socioeconomic conditions prevailing in Sub-Saharan Africa. This was done by reviewing published literature accessed through the internet. Almost all studies exploring micronutrient malnutrition among school children show that it is a big problem in Sub-Saharan Africa which has received little attention. Deficiencies of Iron, Zinc and vitamin A, nutrients which affect immensely the health and well-being of school children, are commonplace in Sub-Saharan Africa, and individual nutrient deficiencies often interact to disrupt educational progress of the children and dampen their future socioeconomic prospects. This could partly be explained by high levels of school dropouts and inadequate foundational skills attained by children upon completion of primary school. It is therefore recommended that Sub-Saharan African countries strengthen schoolchild micronutrient nutrition efforts in conjunction with education provision and poverty alleviation.
