Abstract


The aim of this research was to determine the effects of type and amount of binder on the chemical and physical properties of sweet corn milk-like powder. Sweet corn milk-like powder was prepared from sweet corn kernel extracted with water with ratio of water and kernel of 2:1 (v/w), then dehydrated by spray dryer. Dextrin and arabic gum in various amount i.e. 2.5;  5.0; and 7.5% (w/v), respectively were added to the sweet corn milk-like before drying, and control was also made. The reducing sugar and total sugar, protein, fat, and moisture content, and as well as bulk density, colour, and solubility of the powder were then analyzed. The chemical and physical properties of sweet corn milk-like powder with addition of dextrin and arabic gum in the amount of 2.5; 5.0; and 7.5% (w/v) were significantly different (p > 0.05). According to all aspects studied, sweet corn milk-like powder with addition of dextrin in the amount of 2.5% was the best product of all, which had reducing sugar of 5.00% (db); total sugar 17.01% (db); protein13.67% (db); fat 5.97% (db); moisture 5.38%; bulk density 0.47 g/cm3; and solubility of 93.70%.
