The long and the short of it is that refined coconut oil will last around 18 months. On the other hand, Virgin coconut oil has a shelf life of up to several years.
In addition, Virgin coconut oil keeps more of its natural antioxidants than refined coconut oil, allowing it to be stored longer.
Coconut oil has a much longer shelf life than other vegetable oils, owing to its solid molecular structure and inherent antibacterial capabilities, among other things.
If a liquid or a solid begins to become yellow or brownish while still in its original state, it has likely been beyond its expiry date.
Fresh coconut oil has a silky texture that is easy to spread. However, if your coconut oil begins to separate and get lumpy, it is ruined.
It should have a mild, somewhat pleasant scent if it is good coconut oil. Rancid oil may be identified by its strong or sour scent when you take a sniff of it.
Coconut oil should have a somewhat sweet taste, similar to how it smells when heated. If the flavor is too strong or bitter, throw it.
Store coconut oil in a cool, dark area to keep it fresh. Coconut oil may go rancid very fast if exposed to light, air, or heat.
