Chemical characteristic of virgin coconut oil

Nur Arbainah S. A., . and Mohd Roji S., . (2010) Chemical characteristic of virgin coconut oil. [Proceedings Paper]

The extraction of virgin coconut oil VCO had been carried out using three different processes which are wet process fermentation dry process screw pressing and integrated wet process churning process. The extractions were carried out below 50C in order to preserve the heat labile components in VCO. In this study the yield quality characteristics and the minor bioactive compounds were reported. The VCO yield from the oil for wet dry and integrated wet process is respectively 13.74 0.46 30.0 2.0 and 25.45 1.60. The characteristics that include iodine value free fatty acid peroxide value and moisture content were measured in oil extracted by wet dry and integrated wet process respectively. Iodine value is 5.69 0.79 5.72 0.98 and 4.08 0.11; moisture content is 0.15 0.02 0.13 0.01 and 0.12 0.003; free fatty acid as oleic acid is 0.09 0.01 0.08 0.01 and 0.06 0.005; and peroxide value meq 02/kg oil is 3.7 0.32 4.16 0.21 and 2.83 0.28. The minor bioactive compounds such as polyphenol and atocopherol in the VCO were also compared. The polyphenols content per GAE/g oil extracted by wet dry and integrated is respectively 3.89 0.10 mg 4.17 0.08 mg and 4.34 0.09 mg; p-carotene is 3.53 1.26 mg/g oil 3.89 1.75 mg/g oil and 4.04 0.87 mg/g oil and the a-tocopherol is 0.64 0.31 ppm and 40.00.11 ppm. The result shows differences in VCO samples could arise from the different processing method.

Abstract

The extraction of virgin coconut oil VCO had been carried out using three different processes which are wet process fermentation dry process screw pressing and integrated wet process churning process. The extractions were carried out below 50C in order to preserve the heat labile components in VCO. In this study the yield quality characteristics and the minor bioactive compounds were reported. The VCO yield from the oil for wet dry and integrated wet process is respectively 13.74 0.46 30.0 2.0 and 25.45 1.60. The characteristics that include iodine value free fatty acid peroxide value and moisture content were measured in oil extracted by wet dry and integrated wet process respectively. Iodine value is 5.69 0.79 5.72 0.98 and 4.08 0.11; moisture content is 0.15 0.02 0.13 0.01 and 0.12 0.003; free fatty acid as oleic acid is 0.09 0.01 0.08 0.01 and 0.06 0.005; and peroxide value meq 02/kg oil is 3.7 0.32 4.16 0.21 and 2.83 0.28. The minor bioactive compounds such as polyphenol and atocopherol in the VCO were also compared. The polyphenols content per GAE/g oil extracted by wet dry and integrated is respectively 3.89 0.10 mg 4.17 0.08 mg and 4.34 0.09 mg; p-carotene is 3.53 1.26 mg/g oil 3.89 1.75 mg/g oil and 4.04 0.87 mg/g oil and the a-tocopherol is 0.64 0.31 ppm and 40.00.11 ppm. The result shows differences in VCO samples could arise from the different processing method.
