Potato starch powder (S4251, CAS: 9005-25-8, Sigma Aldrich, Steinheim, Germany) was utilized in this experimental work. Before its use, it was characterized by chemical and physical measurements. Potato starch composition was 13.5% moisture content (determined according to the method 925.10, AOAC, 2005), 0.8% fat (determined according to the method 922.06, AOAC, 2005), 0.3% ash (determined according to the method 923.03, AOAC, 2005) and 25% amylose (determined by Megazyme amylose/amylopectin assay kit, Megazyme International Ireland Ltd., Wicklow, Ireland).
Potato starch particle size distribution was evaluated by dynamic light scattering (DLS), using a Malvern Mastersizer 2000 instrument (Malvern Instruments Ltd., Worcestershire, UK). A monomodal distribution was determined with a D [4.3] of 48.75 µm, and a volumetric distributions of 3% of d(0.1) = 19.53 µm, 10.5% of d(0.5) = 45.52 µm and 5.66% of d(0.9) = 89.81 µm.
