Influence of drying method and location on proximate chemical composition of African metallic wood boring beetle, Sternocera orissa (Coleoptera: Buprestidae) in Republic of South Africa
Composition of proximate chemical composition in edible insects may depend on drying method and/or vegetation (location). Influence of drying method and location on proximate chemical composition of African metallic wood boring beetle (Sternocera orissa), widely consumed in certain rural communities of Limpopo Province, South Africa, was investigated. Randomised complete block design in a 3 × 3 factorial...

Proteolytic and lipolytic activities of Pseudomonas spp. isolated from pasteurized milk
Psychrotrophic bacteria have been recognized as a recurring problem in refrigerated storage and distribution of perishable food products. This study was performed to isolate, characterize and evaluate the prevalence of Pseudomonas spp. in pasteurized milk. Thirty five (35) pasteurized milk samples were collected aseptically from different dairy shops, supermarkets and groceries in different areas in Sadat...

Effects of processing methods on nutrient retention and contribution of white yam (Dioscorea rotundata) products to nutritional intake of Nigerians
Consumption of indigenous foods is being encouraged globally as a means of meeting dietary needs of people. Yam products constitute staple source of energy to many Nigerians but little is documented on their nutrient composition. This study was carried out to determine the effects of processing methods on nutrient retention and possible contribution of some diets prepared from yam to nutrient intake of consumers. Fresh...

Effect of moisture content on some physical properties of two acha varieties (Digitaria exilis and Digitaria iburua)
The effect of moisture content on some physical properties of two varieties of acha was investigated. The moisture content levels used were 10, 14, 18, 22 and 26% dry basis (d.b.), and the two acha varieties used were Digitaria exilis and Digitaria iburua. Increase in moisture content from 10 to 26% resulted in a decrease in bulk density, solid density, porosity and specific gravity for both acha...

Synthesis and characterization of sodium carboxymethylcellulose from pod husk of Cacao (Theobroma cacao L.)
Cacao pod husk (Theobroma cacao L.) is a by product of the cacao industry, rich in cellulose. The methodology to synthesize and uniqueness of the sodium carboxymethylcellulose (Na-CMC) is suggested by cellulose extraction from pod husk of cacao. Na-CMC was synthesized by using 20 ml NaOH at five various concentrations (11.59, 15, 20, 25, and 28.41% w/v) at 25°C for 1 h;...
