Palm kernel oil is a tropical cooking oil that’s shelf-stable. However, like all oils, it’s best when used sooner than later.
Palm kernel oil typically has a shelf life of about 1 to 2 years if stored correctly. After opening, it can last for 6 months or more if kept in optimal conditions.
Below, I’ll explore the shelf life of palm kernel oil, how to tell if it has gone bad, and the best storage practices to keep it in pristine condition. Let’s dive in!
Organic Palm Oil is considered to be relatively long-lasting – if stored correctly, it can last for at least 12 months without becoming rancid. To ensure your oil is the best quality, however, we’d recommend that you use it within six months. If left for too long, palm oil will become ‘rancid’.
How to tell if palm kernel oil has gone bad
Here are some indicators that your palm kernel oil may have gone bad:
- Rancid palm kernel oil emits an unpleasant, sour, or musty smell. If your oil smells anything other than neutral or slightly nutty, it’s time to discard it.
- Fresh palm kernel oil has a mild, nutty flavor. If your oil tastes bitter, sour, or rancid, it’s no longer suitable for cooking.
- Check for any unusual changes in color or texture. Spoiled palm kernel oil may become cloudy, thick, or develop mold-like growths.
- When heated, fresh palm kernel oil has a high smoke point. If it starts smoking at lower temperatures than usual, it could be a sign of spoilage.
- Examine the bottle for any signs of damage or leakage. A compromised container can expose the oil to air and contaminants, leading to quicker spoilage.
How long does palm kernel oil last after opening?
Once you’ve opened a bottle or container of palm kernel oil, its shelf life is generally shorter than unopened oil. However, it can still last for 6 months to a year if stored properly. Like palm oil, palm kernel oil is best when used within the first 6 months of opening.
By refrigerating palm kernel oil, you can typically extend its shelf life even further compared to storing it at room temperature. It can last up to 1 year fridge.
However, keep in mind that refrigerated palm kernel oil may become somewhat solidified due to the cooler temperatures, but it will liquefy again at room temperature or when gently warmed.
| Room temp (counter/pantry) | Fridge | |
| Sealed palm kernel oil | Up to 2 years | 2+ years |
| Open palm kernel oil | 6-12 months | 1 year |
Certainly! Palm kernel oil, like many other food products, often comes with a “best by” or “use by” date stamped on the packaging. However, it’s important to understand that this date is typically more of a guideline than a strict rule. Palm kernel oil can often be used safely beyond its expiration date if it has been stored correctly.
Of course, you should check the oil for any signs of spoilage before going ahead and using it (which I’ll explain next).
For the best results, particularly in recipes where the oil’s flavor matters, using fresh oil is best. Always trust your senses and exercise caution when using any food product that has passed its expiration date.
