ABSTRACT Fungi spoilage organisms are silently invading acidifying, fermenting, discoloring, and disintegrating microbes that render corn unpalatable and unsafe. Fungi spoilage is caused by two factors, (biotic) living which includes insects, birds, rodents and... Continue Reading

ABSTRACT Fish is highly nutritious with high protein content. However, it is a suitable medium for growth of microorganisms, if poorly processed (Oparaku and Mgbenka, 2012). The growth of microorganisms and other non-microbial activities such as lipid oxidation contribute to the deterioration of fish products (Martin, 2010). An increase in the... Continue Reading
