This study investigated mycotoxin concentrations in fermented sun-dried cocoa beans as affected by cola nut powder and cola nut extract using a 2 × 4 full factorial experimental design with treatment type (cola nut powder; cola nut extract) and…

The response surface methodology and central composite rotatable design for K=3 was used to investigate the combined effects of ripening, salting and duration of fermentation on total viable cells (TVC) load, sodium chloride (NaCl) and histamine…

A 3 x 2 x 2 factorial experiment with fermentation time (0, 24, 48 hours), cowpea (0 and 15%) and alkaline treatment (nixtamalized and non-nixtamalized corn) was used. The blends were dried using a cabinet drier, milled into flour and spices added…

The trifoliate yam, Dioscorea dumetorum tuber is the most nutritious among the yam species consumed. Its consumption is however constrained by a rapid post-harvest hardening phenomenon that occurs after 24 hours of harvest, rendering them unsuitable…

The two enzymatically produced sunflower oil based cocoa butter equivalents (CBEs) were blended with cocoa butter (CB) at varying concentrations (g/100 g). The peak maximum decreased significantly upon the addition more CBE due to the presence of the…

Response surface methodology was employed to characterize the effects of blanching temperature, blanching time and final frying time on texture and appearance of fried yam chips produced from two cultivars of white yam (Dioscorea rotundata). Fifteen…

Browning in raw and processed yams resulting from enzymes, polyphenol oxidase (PPO) and peroxidase (POD), activities is a major limitation to the industrial utilization of Dioscorea varieties of yams. Two elite cultivars of D. rotundata species were…

Fermentation and cowpea steaming can be used to improve the protein quality and quantity of fermented maize dough. In the production of maize-cowpea blends, it is important that the quality characteristics are evaluated to determine their…

Response surface methodology (with central composite rotatable design for k0/3) was used to investigate the product properties of extruded riceÁ/cowpeaÁ/groundnut blends in a single screw extruder. The combined effect of cowpea (0Á/20%), groundnut…

Biochemical and textural changes were investigated in trifoliate yam Dioscorea dumetorum tubers, after harvest, in an attempt to study the chemical and physical changes associated with the raw and cooked tubers and how these relate to the hardening…
