Fungal and aflatoxin contamination of some human food commodities in Nigeria
This paper provides data of investigation of fungal, aflatoxins M1 (AFM1) and B1(AFB1) contamination of three hundred and forty three samples of five different food commodities from three States in Nigeria. Maize samples from Niger (43) and Kogi (50) States and dried yam chips (50) from Niger State were purchased and assessed for fungal contaminants. Seventy (30 each from the maize samples and 11 from yam chips) of...

Effect of fortification of maize with cowpea and iron on growth and anaemia status of children
Iron and iron deficiency anaemia is of concern globally, and most vulnerable are children and women. In Ghana, after six months of age when breast milk is not enough, children are given cereal-based gruels which are poor in nutrients. Addition of cowpea to maize improved nutrient quality but not enough to meet iron needs. We investigated the effect of iron-fortified maize-cowpea blend in controlling iron deficiency...

Effect of some plant-based insecticides on the nutritive value of smoked catfish, Clarias gariepinus (Pisces: Clariidae)
The biochemical composition of smoked African mud catfish, Clarias gariepinusBurchell treated with four tropical plant materials, Dennettia tripetala, Eugenia aromatica, Piper guineense and Monodora myristica for the control of Dermestesmaculatus was determined. 10 g of plant powders and 5 ml of 10% concentration of extracts were separately applied onto 1000 g...

Assessment and degradation study of total carotenoid and ß-carotene in bitter yellow cassava (Manihot esculenta Crantz) varieties
The assessment of the variability of total carotenoid, ß-carotene, all-E, and 13 and 9-Z-ß-carotene isomers in twelve bitter yellow cassava was carried out, as well its degradation in five varieties after flour processing and during storage. HPLC and UV/ visible spectrophotometry were used in sample analyses. Varieties of bitter yellow cassava presented variation in the total carotenoid contents from...

Effects of processing techniques on the nutritional composition and anti-nutrient content of mucuna bean (Mucuna pruriens L.)
Mucuna bean (Mucuna pruriens) is an indigenous legume promoted in Kenya as a green manure cover crop. It contains high protein but it is under - utilized due to the presence of 3, 4-dihydroxy-L-phenylalanine (L-Dopa) and other anti nutritional compounds. To improve its nutritional potential as a protein source, mucuna bean was processed and evaluated for nutritional composition. Effects of...

Isolation and characterisation of CPP (casein phosphopeptides) from fermented milk
The fermented milk peptides have a varied composition and they contain CPP (casein phosphopeptides) which has a wide array of uses. The study was undertaken to isolate CPP from fermented milk and it was then characterised using appropriate techniques. The 3 parameters of viscosity, titrable acidity and pH were standardised before commencing the studies. The antimicrobial activity of the CPP was...

Determination and comparison of nutrient and mineral contents between cultivated and indigenous edible mushrooms in Central Malawi
The production of cultivated mushrooms and utilization of both cultivated and indigenously grown edible mushrooms have been on the increase in modern times especially due to their nutritional importance. A comparative study on the selected nutrient and mineral contents of two cultivated and two indigenously grown edible mushrooms were carried out at Bunda College of Agriculture in Lilongwe, Malawi between the...

Production of a non-alcoholic beverage from sweet potato (Ipomoea batatas L.)
Sweet potato tubers were processed into non-alcoholic beverage flavored with citrus lime and ginger. Two varieties namely faara and sauti were used. pH, total sugars, total solids, brix, total titrable acidity, vitamins C and A were determined and sensory evaluation was conducted on the products to assess the acceptance preference. Values for pH ranged from 3.81 to 4.34 and that for degree brix was...

Diversity and nutritional value of foods consumed by children in two agro-ecological zones of Benin
Food diversification is recognized as an approach to reduce nutrient deficiencies among the population. Samples of food commonly consumed by the children in two agro ecological zones (Coastal Savannah Zone in the South (CSZ) and Sudan Savannah Zone in the North (SSZ)) of Benin were collected for energy, protein, fat, iron, zinc and vitamin A contents determination. Energy content ranged from 76 to 82 kcal/100 g (wet...

Monitoring of aflatoxins and heavy metals in some poultry feeds
Aflatoxins and heavy metals were investigated in some poultry feed samples used as starter, grower, developer, layer, rabbit feed and bran which obtained from the local market at Al-Qassim region, Saudi Arabia. The results indicated that different amounts of aflatoxins were found in the analyzed samples. They reached peak values of 70.6, 46.38 and 50.88 µg/ kg sample for...
