ABSTRACT This work is aimed at the production of laundry starch, using locally sourced raw material (cassava tuber), by extraction of the starch granules from the tubers, 80kg of the harvested fresh cassava tubers were peeled and washed twice to remove dirt and earth. The peeled cassava tubers were re-weighed. 75kg of the peeled tubers was grated... Continue Reading

ABSTRACT The starches of corms and cormels of red and white cocoyam (Colocasia esculenta) varieties, cassava (Manihot esculenta), sweet potato (Ipomea batata), bitter yam (Dioscorea dumentorum) and water yam (Dioscorea alata) were extracted. Their proximate compositions, physicochemical properties, mineral compositions and antinutrient contents... Continue Reading

ABSTRACT The food potentials of tigernut tubers (Cyperus esculentus) locally know as “aki awusa” in Igbo, ”aya” in Hausa and “ofio” in Yoruba were evaluated. The proximate composition of 100g of raw and processed tigernuts showed that moisture content of tigernuts ranged from 4.19 – 51.93 %, crude protein 2.61 – 10.12 %, ash 0.70... Continue Reading

ABSTRACT  Fungi associated with the spoilage of cocoyam ( Colocasia esculenta ) during storage at ambient temperature (28+20c) was investigated in this study. This was done by cutting the damaged portion of the cocoyam tubers and blend with diluents (water) to have even distribution of the microorganism and ensure ease of plating out. This done...

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

ABSTRACT Foods and microorganisms have long and interesting associations which developed long before the beginning of recorded history. Foods are not only nutritious to consumers, but are also excellent sources of nutrients for microbial growth. Depending on the microorganisms present, foods may spoil or be preserved by fermentation. Foods can act... Continue Reading
