Assessment of heavy metal concentrations in urban grown vegetables in Thika Town, Kenya
Consumption of leafy vegetables grown in urban areas contaminated with heavy metals is a major source of health problems for both humans and animals. This study was conducted to analyze the heavy metal levels in tomato (Lycopersicon esculentumL.) and spinach (Spinacia oleracea L.) grown in Thika town. Heavy metal concentration was analyzed using Atomic Absorption Spectrometry. The mean concentrations of lead (Pb),...

Protein quality and sensory evaluation of moin-moin prepared from cowpea/maize flour blends
The proximate composition, acceptability and nutritional evaluation of moin-moin prepared from cowpea/maize flour blends in the ratio 100:0 (sample A, control), 80:15 (sample B); 75:25 (sample C), 65:35 (sample D), 50:50 (sample E), 40:60 (sample F) and 30:70 (sample G), respectively were investigated. Protein quality was evaluated by feeding 28 days-old weaning albino rats with 10% protein diets formulated with sample...

Variations in physico-chemical and sensory qualities of canned unpeeled halved tomatoes as influenced by cultivar, soak treatment and brine composition
The composition of two commonly consumed tomato cultivars (Ibadan-Local and Roma-VF) and their physico-chemical and sensory qualities after thermal processing under various conditions were evaluated. Fresh Ibadan-Local had higher titratable acidity (0.66 and 100 g) while Roma-VF had higher ascorbic acid (23.22 mg/100 g). Soluble solids, pH, total solids and lycopene were not significantly different (P>0.05). The...

Factors influencing the use of adequately iodated salt in Ghana
Ghana is one of the largest producers of salt in West African region yet, access to and the use of adequately iodized salt is not widespread. Using the Ghana Multiple Indicator Cluster Survey (MICS) 2006, this paper examined the factors influencing the use of adequately iodized salt in Ghana. Factors that influence the use of adequately iodized salt included knowledge, access to information and the wealth status. Where...

Isolation of pathogenic bacteria from some foods sold at selected private schools in Akoka area of Yaba – Lagos, Nigeria
A total of sixty-four samples of four cooked foods from sixteen private primary schools in Akoka area of Yaba, Lagos, Nigeria were investigated for the occurrence of pathogenic bacteria. The area was divided into four zones, namely; Akoka north, Akoka south, Akoka east and Akoka west, using the four cardinal points. Four private primary schools were then selected from each of these zones. The standard plate count...

Effect of post harvest treatments on quality of whole tomatoes
Tomato (Lycopersicon esculentum Mill) is one of the most important vegetable crops cultivated all over the world for its fleshy fruits. In this work, the influence of various post harvest treatments and storage conditions on the various physico-chemical changes associated with tomatoes was investigated. The treatments consisted of sodium metabisulphite, calcium chloride dip, citric acid dip, lemon juice dip,...
