For the film preparation, the aqueous dispersions of starch pullulan
mixtures were pasted according to the procedure
described for RVA analysis without the final cooling and holding
steps. The hot paste was centrifuged for 2 min at 840 g to remove
air bubbles, and thenwas casted to films by a film applicator (COAD
411, Uiwang, South Korea). The films prepared were then dried at
50 C and RH 50% for 2 h prior to analyses.
