attributed to the depression of repulsive electrostatic
forces between adjacent droplets, led to strong flocculation formation
and thus, phase separation, while at above 0.15%, flocculation
formation and phase separation were greatly slowed down by the
high viscosity of the XG/EMG emulsions, leading to stable emulsions.
The PV and TBARs values, and hexanal concentrations indicated
reduced lipid oxidation in emulsions containing XG/EMG
gum mixtures. Although the PV and TBARs values indicated a considerable
reduction in lipid oxidation during the 14-day storage, no
significance difference (P > 0.05) was observed among the emulsions
containing XG/EMG gum mixtures and other emulsions.
Therefore, this study recommends future studies where lipid oxidation
measurements should be conducted for a longer period of
storage. This study has helped in identifying the optimum concentrations
of XG/EMG gum mixtures that allow incorporation of the
omega-3 polyunsaturated fatty acids to produce thermodynamically
stable oil-in-water emulsions
