Physical stability of kenaf seed oil-in-water nanoemulsion was improved by optimising three-component emulsifier mixtures that produced using high pressure homogeniser.
The optimum proportions of emulsifier mixture obtained was 64.9% (w/w) SC, 6.4% (w/w) GA, and 28.7% (w/w) T20.
The optimum ternary emulsifier mixtures showed a good synergistic stabilising effect.
The optimised formulation was stable at both chill (4 °C) and room temperature (25 °C) over 1 month of evaluation.
