DOIAbstract
In this research, complex coacervation between soy protein isolate (SPI) and gum arabic (GA) constituted a preliminary step for developing chia oil (CO)-in-water emulsions suitable for subsequent spray-drying. The contributions of total biopolymer concentration, SPI-GA ratio w/w and ionic strength on coacervate yield (CY) were quantified through a 3×6×4 factorial design. The SPI-GA ratios that gave the highest CY values (1-1 and 2-1) were selected to prepare emulsions and blank dispersions (devoid of CO). The preparation process included four well-defined sequential steps: high speed homogenization, high pressure homogenization, complex coacervation and a carrier addition (maltodextrin). The emulsification step, the SPI-GA ratio and the pre...
