2.3.2. pH treatment
Freshly extracted coconut milk has a pH 6 (control). The pH of
coconut milk emulsion was varied between 3 and 5 using 0.1 N
HCl and pH 7 and 10 using 0.1 N NaOH. The samples were allowed
to stand for 2 h at ambient temperature (29 ± 2 C) to destabilize
the coconut emulsion. Then they were subjected to centrifugation
at 3585g for 10 min to separate coconut cream and aqueous
phases. Finally, coconut cream was centrifuged at 4880g for
15 min to obtain oil.
2.3.3. Chilling treatment
The coconut milk emulsion were chilled at different temperatures
(5, 10, 15 and 20 C) for 6 h and thawed to ambient conditions
(29 ± 2 C). Further, thawed coconut milk emulsion was
centrifuged at 3585g for 10 min to obtain coconut cream and aqueous
phases. Coconut cream was subjected to centrifugation at
4880g for 15 min to obtain oil.
