Augusto, you need to evaluate zeta potential X pH, then pH X ratios (protein and arabic gum at some defined concentration). After mixture, proceed to centrifugation and try to measure protein and arabic gum present in each phase. I believe that you can optimize your coacervation process. If you need, please use my e-mail address ([email protected]). Sincerely yours, Carlos Grosso.

Thanks for your explanation.

Sincerely yours, Augusto

Hi Augusto, optimization of complex coacervation process takes some time. You can measure the zeta potential and strength of electrostatic interaction, complex coacervate yield and turbidity values to find where the optimum complex coacervation occcurs. You can read two papers from our group.
