Best fitted thin-layer re-wetting model for medium-grain rough rice
Five commonly cited thin-layer rewetting models, that is, Diffusion, Page, Exponential, Approximate form of diffusion and Polynomial were compared for their ability to fit the experimental re-wetting data of medium grain of rough rice, based on the standard error of estimate (SEE) of the measured and simulated moisture contents. The comparison shows that the Diffusion and the Page models have almost the same ability to...

Development of trifoliate yam: Cocoyam composite flour for fufu production
Trifoliate yam (Dioscorea dumetorum) tubers and two varieties of cocoyam (Nxs001 and Nxs003) were processed separately into flour and mixed at the following proportions: 100% trifoliate yam flour; 100% cocoyam flour; 85:15, 75:25, 25:75, and 50:50 cocoyam- trifoliate yam flour. The functional and pasting properties of the composite flours were determined. The trifoliate yam-cocoyam flours were then reconstituted, made...

The quality of maize stored using roof and sack storage methods in Katumba Ward, Rungwe District, Tanzania: Implications on household food security
The quality of maize stored using sack and roof storage methods was studied by investigating the presence of Fusarium, Aspergillus and Penicillium infections using qualitative methods in 130 maize samples that were randomly collected from the roof and sack storage facilities in Katumba ward, Rungwe district, Tanzania. Levels of fumonisins, aflatoxins, ochratoxins and T-2 toxins were determined using quantitative methods...
