A Minipaster apparatus, based on a Haake Rotary Viscometer, was developed to investigate thermal pasting of aqueous starch suspensions, and to study the effects of varying heating rate, holding time and holding temperature, and of varying starch concentration. Comparison has been made with a Brabender Visco‐amylograph. Attention is drawn to the marked serial dependence of the simple pasting parameters, peak viscosity temperature, peak viscosity, breakdown viscosity and setback viscosity. Relative breakdown and setback, and various ratios of pasting parameters are not markedly superior to the simple parameters as discriminants between starches.
