Item Effect of fermentation time and mix ratio on some nutritional qualities of the dry mixture of maize and sorghum powder (Ogi)(Faculty of Technology, Josip Juraj Strossmayer University of Technology, Osijek, Croatia., 2017) Odewole, MM; Sunmonu, MO; Opaleke, DO; Adeyinka-Ajiboye, O; Sani, ROA; Aiyejoritan, MTThe effect of two process conditions (fermentation time (B) and mix ratio (A)) on the dry mixture of maize (M) and sorghum (S) powder (ogi) was investigated. Five mix ratios (1 (M50:S50), 2 (M60:S40), 3 (M70:S30), 4 (M80:S20), 5 (M90:S10)), and five fermentation times (6, 12, 18, 24 and 30 h) were considered. The drying was done at 50 °C in a convective fabricated cabinet dryer. It took about 2 hours for the drying to be completed. After drying, all samples were analysed for the output parameters (carbohydrate, crude fibre crude protein, fat content, vitamin C and magnesium content). The results showed that the interaction of all the levels of the two process conditions did not change the mean values of the carbohydrate, crude protein and magnesium contents of the dried fermented product (ogi powder). Various combinations of all the levels of the two process conditions did not cause the value of the carbohydrate, crude fibre, crude protein, fat, vitamin C and magnesium content to be higher than 83.5%, 0.6%, 3.2%, 1.2%, 3.0%, and 3.85 mg/100g respectively.Item Willingness to Pay for Detached Mallow Leaves (Corchorous Olitorius) among Vegetable Consumers in Kwara State, Nigeria.(2017) Ajibade, TB; Omotesho, KF; Animashaun, JO; Opaleke, DO; Ajibade, ETThis study was carried out to examine vegetable consumer’s willingness to pay for detached Mallow leaves (Corchorous Olitorius) in the study area. Primary data was used for the study. Survey instrument used was structured questionnaire, administered to 120 respondents randomly selected in a three-stage sampling procedure. Analytical tools employed include descriptive statistics, Contingent Valuation Method and Binary logistic regression technique. The study revealed that vegetable related purchases are predominated by female, accounting for up to 62% transactions. About 69% of the respondents were willing to pay 60% premium per bundle ofdetached Mallow leaves. At 5% level, factors that significantly determine consumers’ willingness to pay for detached Mallow leaves are consumers’ awareness of the health and nutritional benefits and also bid price being premium for detaching the Mallow leaves.
