| Production, characterization and development of models for glucose syrup obtained from selected agricultural crops were studied. Glucose syrups were produced at 60, 80 and 100oC. The rheological properties of the glucose syrups were investigated and the effect of temperature on viscosity was determined. Also, the effect of shear rate on viscosity was determined at spindle speeds of 10, 20, 50 and 100 rpm. Data obtained were fitted into Power law model for analyzing the viscosity and for fluid classification. The starch yields were 71.7, 85.3 and 91.5% and the syrup yields were 78.82, 86.35 and 88.65% for maize, rice and cassava respectively. Viscosities of the syrups showed an inverse relationship with temperature and shear rates. The power law index (n)... |
