Mutation assay with Salmonella typhimurium enabled us to detect various types of mutagens in cooked foods. A series of mutagenic heterocyclic amines has been isolated and identified in broiled fish and meat and in pyrolyzates of amino acids and proteins. Feeding experiments showed these mutagens to be carcinogenic in mice and rats. The mechanism of formation and pathway of metabolic activation ...

Yam (Dioscorea opposita) is commonly consumed in East Asia, but allergic reaction to this plant food is rare. To date, there is no report of anaphylactic reaction after ingestion of cooked yam. We described 3 cases with anaphylaxis after eating boiled yam and 1 present with oral allergy syndrome as well. Basophil activation test in patients showed positive reactivity to boiled yam extract. In i...

In developed countries which are at the epicenter of the obesity pandemic, pulse crop consumption is well below recommended levels. In a recent systematic review and meta-analysis of 21 randomized controlled clinical trials, pulse consumption was associated with improved weight control and reduced adiposity, although the underlying mechanisms were a matter of speculation. Common bean (Phaseolus...

BACKGROUND Limited data exist on the contribution of dietary sources of arsenic to an individual's total exposure, particularly in populations with exposure via drinking water. Here, the association between diet and toenail arsenic concentrations (a long-term biomarker of exposure) was evaluated for individuals with measured household tap water arsenic. Foods known to be high in arsenic, includ...

Neural networks are an extremely powerful tool for data mining. They are especially useful in cases involving data classification where it is difficult to establish a specific pattern in the search space. In an era when artificial intelligence is increasingly being utilised in industrial and medical applications throughout Africa, it is becoming evident that this is an emerging trend in the con...

One of the consequences of intense genetic selection for growth of poultry is the recent appearance of abnormalities in chicken breast muscles, such as white striping (characterised by superficial white striations) and wooden breast (characterised by pale and bulged areas with substantial hardness). The aim of this study was to evaluate the quality traits of chicken fillets affected by white st...

Polycyclic aromatic hydrocarbons, PAHs are carcinogenic, mutagenic and persistent organic compounds commonly generated from incomplete combustion of matters. Beans, Phaseolus vulgaris maize, Zea mays form part staple foods consumed highly rich in protein carbohydrate respectively. This study compared the concentration levels sixteen priority different types beans (Potasikum, white...

Alternative cooking energy to replace wood fuels is needed in the African context. Liquified Natural Gas (LNG) a solution but still based on burning fossil fuel. Electrical cookers can be an alternative as well. However, for off-grid systems this means electrical batteries are required, solar electricity from Photovoltaic (PV) panels intermittent, and also made after sunset. Heat storage techno...

seed coat crude extracts of white-coloured ita-256, white and brown-coloured tvs-716, deep brown-coloured it-90k and light brown-coloured ife brown cowpea varieties were analyzed for the presence and amount of total phenol, tannin and flavonoid content. crude extracts of the cowpea varieties were analyzed for antioxidant activity using the thiobarbituric acid (tba) assay. the seed coat extracts...
