| Abstract | Flow characteristics or five tomato ketch—up samples were studied by making viscometric measurements with a Broorfield viscometer and a tube flow VlSCOEeter. a tune flow viscometer was constructed and tested tor the flow characterization. Corrections for the losses in the tune flow were made. The magnitude of the flow constants determined with the tube viscometer were higher than those Obtained with the Brookrield viscometer. This was apparently due to the differences in reSpective shear rates. The flow constants of Ketch~up samples stored for 2, 4, and 8 weeks at temperatures of 5, 27 and 45°C were determined. Empirical procedures based on experimental data were developed to predict the presence or yield stress. It was found that the ketch-up samples possessed no yield stress and the Characteristic flow curves could be adequately represented by the power law model. Centrifugation was studied as a means of develOpihg a physical stability criterion for retcn—up samples. The lepe or the semi-log plot of the percent solids settled to the centrifugation time at a given rotation speed could he expressed as the settling rate constant. In general, the influence or storage period was less pronounced than the temperature. The use of higher centrifugation Speeds and small test tubes is proposed to further increase the sensitiVity or testing procedure. |
