Abstract:
Virgin Coconut Oil (VCO) is a product of coconut fruit {Cocos nucifera)
that contain of Medium Chain Fatty Acid (MCFA), so it can be metaboUzed by
our body. The objects of this research are to produce VCO by acid method and to
determine the quality of VCO. The samples were from Bengalis, Indragiri Hilir,
Pelalawan, and Rokan Hilir. VCO is produced by using acetate acid 25% which
has function to free the oil from fat globular membrane that contain of lipoprotein.
Because of that, optimum pH must be determined. Determining quality of VCO
based on Rancangan Standar Nasional Indonesia 2 (RSNI 2) by using 6
parameters test. The parameters are water value, iodine value, saponification
value, peroxide value, free fatty acid value, and concentration of fatty acid. Water
value in VCO from each sample are not different significantly (P>0,05) about
0,0900 to 0,0975%. Iodine value from each sample are not different significantly
(P>0,05) about 7,2527 to 7,9819 g iod/100 g sample. Saponification value from
each sample are not different significantly (P>0,05) about 259,9214 to 267,8649
mg KOH/g fat. Peroxide value from each sample are different significantly
(P<0,05) with the highest value from Pelalawan (1,5986 mg ek/Kg) and the lowest
value from Bengkalis (0,5239 mg ek/Kg). Free fatty acid value from each sample
are different significantly (P<0,05) with the highest value from Indragiri Hilir
(0,3922%) and the lowest value from Rokan Hilir (0,2516%). The result of
determined fatty acid concenfration is the highest concentration of lauric acid
(51,7%) from Pelalawan compared with Bengkalis, Indragiri Hilir, and Rokan
Hilir. Based on the result of 6 parameters test, coconut from Indragiri Hilir is
recommended as the source to produce VCO.
