Fungi are ubiquitous plant pathogens that are major spoilage agents of foods and feedstuffs. The infection of plants by various fungi not only results in reduction in crop yield and quality with significant economic losses but also contamination of grains with poisonous fungal secondary metabolites called mycotoxins. There is an urgent need to address the food safety and International trade issues associated with mycotoxin contamination in Nigerian consumer goods and agricultural products be...

ABSTRACT Black glutinous rice bran (Oryza sativa L.) is a potential source of the dark purple anthocyanin pigments. This study investigated some quality aspects and bioactive compounds of the colourant powder obtained from rice bran extracted by ohmic heating (OHM) assisted solvent extraction. The moisture content (MC) of the bran sample investigated was adjusted to 30% and 40%. Four different levels of electric field strengths (E) of 50, 100, 150, and 200 V cm– 1 were applied. The results ...
1.1INTRODUCTION The USDA issued a Dietary Guidelines recommendation on June 12th, 2005 for consumers to increase whole grain consumption. However, it is generally recognized that wheat flours containing the germ can develop problems due to lipid changes. White flour, especially soft wheat flour destined for use in cakes, increases in quality with time after harvest and milling, as indicated by a desirable drop in batter specific gravity and increase in batter viscosity, distilled water bind...

Food Technologist who must have a good knowledge of technology materials, labour equipment, money research, engineering and management is in any food-processing establishment. Particularly, food packages purposely protect the products from environment hazards throughout the period of the shelf life. Some industries can even be instituted purposely for food packaging...
The role of packaging in food processing is just one among many ways of food preservation. As soon as food is packaged, it is set for shipment and marketing. For many food technologists to embark on food packaging, the food technologist must have food knowledge of the technology, materials, labour equipments, capital, research, engineering and management involved in any such food processing establishment. The package purposely protects the product from environmental hazards throughout t...
Yams are any of the economically useful plants belonging to the genues Diocorea; yams are also the tubers or rhizomes of these plants (Coursey 1967).
