Complex coacervates of gelatin and sodium hexametaphosphate (SHMP) was used to microencapsulate tuna oil fortified with the multiple functional lipophilic ingredients, vitamin A, D3, E, K2, curcumin and coenzyme Q10. An emulsion homogenization speed of 15,000 rpm for 15 min resulted in low surface oil content (0.08%), high encapsulation efficacy (99.84%) and encapsulation yield (96.59%), with a significantly enhanced oxidative stability index (6.23 h). The Fourier transform infrared spectra showed that there was no observable oxidation of the oil during microencapsulation. This study shows that microencapsulation using complex coacervation is suitable for stabilizing multiple bioactive lipophilic ingredients.
