Physical properties
Coconut oil is a fat consisting of about 90% saturated fat. The oil contains predominantly medium chain triglycerides,[1] with roughly 92% saturated fatty acids, 6% monounsaturated fatty acids, and 2% polyunsaturated fatty acids. Of the saturated fatty acids, coconut oil is primarily 44.6% lauric acid, 16.8% myristic acid a 8.2% palmitic acid and 8% caprylic acid, although it contains seven different saturated fatty acids in total. Its only monounsaturated fatty acid is oleic acid while its only polyunsaturated fatty acid is linoleic acid.[2]
Unrefined coconut oil melts at 24-25°C (76°F) and smokes at 177°C (350°F),[3] while refined coconut oil has a higher smoke point of 232°C (450°F).
Among the most stable of all oils, coconut oil is slow to oxidize and thus resistant to rancidity, lasting up to two years due to its high saturated fat content.[citation needed] In order to extend shelf life, it is best stored in solid form (i.e. below 24.5°C [76°F]).
