Abstract

This study was aimed at evaluation of the effect of enzymatic application (Viscozyme Cassava C) for extraction of Virgin Coconut Oil (VCO) from fresh coconut meat, and comparison of physico-chemical and functional properties of the extracted CVO and cold pressed oil. The parameters influencing the extraction yield included material-to-water ratio (w/v), enzyme concentration (% E/S) and incubation durations (h). The results indicated that the highest yield of VCO (19.58%), presenting 73.58% recovery of oil, from fresh coconut meat was achieved at the water ratio of 1:7, enzyme concentration 1.5% ES, and incubation time 4h. This was lower than that from cold pressing but significantly higher than the oil yield (6.92%) of sample without enzymatic treatment. The quality of VCO was determined by peroxide value (0.317 meqO2/kg), free fatty acid value (0.393 mg KOH/g oil), iodine value (4.88 gI2/100g oil) and total phenolic content (248.25 mg GAE/100g oil) and that was comparable with the quality of the cold-pressed oil. The VCO was rich in short-chained saturated fatty acids, with lauric acid of 46.64%, palmitic acid 8.42% and myristic acid 18.24%. Additionally, the CVO in this study contained unsaturated fatty acids in the amount of 5.57% of linoleic acid and oleic acid.
