| Abstract: | Nowadays virgin coconut oil (VCO)
has become popular locally and as export product
because of its reported health benefit such as
supporting immune system health. The
characteristic that sets this VCO apart from oil is its
high lauric acid (C12) content. The conventional
methods to produce virgin coconut oil (VCO), by
using conventional methods, need longer
processing time (24 – 48 hours) to break natural
o/w coconut milk emulsions. This study
investigates comparatively on emulsion
demulsification between the centrifugation and
combination of centrifugation and chemical
demulsification methods. The percentages of water
soluble materials used for this experiment were
varied from 2, 5 and 7 wt %. These materials are
Polyethylene Glycol 6000 (PEG 6000) and
Polyethylene Glycol 600 (PEG 600) and they have
high influence in demulsification of emulsions.
The centrifuge speed was varied from 6000 rpm to
12000 rpm and the separation time was varied from
30 minutes to 105 minutes. The present research
found that, centrifugation method with the help of
water soluble material can enhance the
demulsification of oil-in-water (O/W) coconut
milk emulsion in a very short time compared to the
conventional methods. |
