摘要: The fatty acid and antioxidant property of pawpaw coconut oil (PCO) and virgin coconut oil (VCO) were compared. GC and GC-MS were used to determine the fatty acid of PCO and VCO, respectively. The results show that there is no obvious difference of fatty acid composition between PCO and VCO. The scavenging rate to ABTS(+)center dot of PCO is higher than VCO at the same proportion. TEAC (Trolox equivalent antioxidant capacity) value of PCO is 67.5 mu mol/l. The complexing ability to Fe2+ of PCO is stronger than VCO at the same proportion. The scavenging ability to DPPH center dot of 40% PCO is weaker than VCO, with the increase of PCO concentration, the difference of the scavenging ability to DPPH center dot between PCO and VCO is smaller.
