2.8. Determination of pasting properties
Pasting properties of the flour slurry containing 3.0 g on a
dry basis (db) of flour in 25 mL of distilled water were
measured by a Rapid Viscosity Analyzer (RVA) (New Port
Scientific Instrument and Engineer, Warri water, Australia).
The flour dispersion was held at 50 C for 1 min, heated from
50 to 95 C at a heating rate of 12 C/min, held at 95 C for
2.5 min and cooled to 50 C at the same rate. Amylograms
describing pasting characteristics included: pasting temperature;
peak viscosity; peak time; pasting temperature; breakdown
viscosity; final viscosity; and setback value. The RVA measurements
were performed in triplicate.
