Coconut milks were extracted from ground coconut meat by adding phosphate buffer (pH 6.2) to ground coconut meat at a weight ratio of 1:2.5. The mixtures between ground coconut meat and buffer were manually pressed and filtered through filter cloth to remove solid residues. The fat con- tents in extracted coconut milks were determined by using Rose-Gottlieb method. The extracted coconut milks were further diluted with phosphate buffer (pH 6.2) to a final fat content of 20 wt%. Sodium azide (antimicrobial agent) at a concentration 0.02 wt% and ESL at a concentration of 1- 9 wt% were added to coconut milks. Coconut milks after addi- tion of ESL were left overnight and slightly warmed until all ESL fully dissolved. Coconut milk emulsions in an amount of 100 g contained 20 wt% coconut oil, 1–9 wt% ESL, and distilled water were prepared by the same homogenization method above.
