Bioactive and nutritional compounds in virgin coconut oils
Chitraporn Ngampeerapong1, Visith Chavasit2, Robert W. Durst3.
Introduction: Virgin coconut oil (VCO) is very much in demand among healthconscious
consumers. VCO is produced from fresh coconut milk by using
centrifugation (CVCO) or fermentation (FVCO). Since the conditions used for these
processes are quite different, this study aimed to investigate their effects on the
contents of selected bioactive compounds that have potential health benefits.
Methods: CVCO and FVCO were produced from the same batch of fresh coconut
(Cocos nucifera L.) milk. CVCO was obtained by centrifuging coconut milk in
three steps with vacuum evaporation, while FVCO was obtained by anaerobically
fermenting coconut milk at 35°C for 16 h. The products were analysed for
macronutrients, fatty acid profiles, phytosterols and phenolic compounds.
Potential health benefits were determined by calculating the chance of fatty acid
bioavailability and analysing antioxidant activities.
Results: Both VCO production
processes removed all hydrophilic compounds, with the remaining fat and moisture
contents not significantly different at 99.90% and 0.10%, respectively. Their fatty
acid profiles were 90% saturated and 60% medium chain (mainly lauric acid). The
phenolic compound (originally found high in coconut milk) was present in trace
amounts in the VCOs. However, phytosterols became more concentrated. Chances
of medium chain fatty acid becoming more available for health benefit were at
54% and 58%, and were insignificant among both VCOs. Fermentation caused
more rancidity to the product.
Conclusion: Both centrifugation and fermentation
production processes did not qualitatively and quantitatively affect the bioactive
compounds of virgin coconut oil.
