Fig. 1. (a) Coacervation of SPI and GA as a function of pH. The coacervation was implemented in the SPI/GA ratio 1:1. (b) Coacervation of SPI and GA as a function of ionic strength. The coacervation was implemented in the GA/SPI ratio 1:1 and pH 4.0 and the ionic strength was presented in NaCl concentration. Values were expressed as mean values ±SD of three independent experiments and error bars were the standard deviations of the values. Means with different letters differed significantly at P < 0.05.
