Pasting properties
A microviscoamylograph (Visgraph-E, Brabender Instruments,
Inc., Germany) was used to determine the viscosity profiles (in
Brabender units, BU) of the starch samples. Dispersions of BRS
(6%, dry basis) were transferred to the microviscoamylograph
and subjected to thorough agitation. The dispersion was brought
to an initial temperature of 30 C and subsequently to 95 C at a
rate of 1.5 C/min. The temperature of the dispersion was maintained
at 95 C for 30 min; subsequently, the dispersion was cooled
to 50 C at a rate of 1.5 C/min and maintained at 50 C for 30 min
