Canola oil is a popular cooking oil in many a kitchen, both commercial and non-commercial. Usually, I just see it plonked on countertops right near the stovetop for easy access, I assume. But is that the best way to store it? And should it really be in those big, clear plastic bottles?
It turns out you may be storing it the wrong way; as with any kind of oil, it is advised to keep it away from heat and light! Let’s look into it a bit more.
How To Store Canola Oil
When not in use, it is recommended to store canola oil in a cool, dark place away from direct sunlight and heat sources (and that includes right near your stove!) This helps prevent oxidation and rancidity, which can lead to the oil developing off-flavors and odors.
In the short term, a cool dark cupboard can suffice as a storage location, as it offers protection from light and air exposure. However, for long-term storage, especially beyond one month, it is advisable to choose a very cool and dry spot in the kitchen. Lower temperatures help slow the oxidation process, preserving the oil’s freshness for a longer period. You may even want to transfer it into a dark glass bottle to further prevent light from getting to it.
Remember to seal the bottle tightly after each use to minimize air exposure. This simple step can further help maintain the quality and extend the shelf life of your oil.
Can You Freeze Canola Oil?
It is not recommended to freeze canola oil as it alters the oil’s structure and does not extend its shelf life. The oil maintains its quality for about a year, whether stored in the freezer or pantry. However, freezing the oil can affect its structure and shorten its shelf life once thawed. So, why bother?
How To Defrost Canola Oil
If, for some reason, you do have frozen canola oil that needs to be defrosted, thawing it is easy peasy and can be done using a couple of different methods.
One way is to allow it to thaw naturally by taking the canola oil out of the freezer and sitting it on the countertop until it reaches room temperature. As it warms up, it will melt back into a liquid state.
If you’re in a hurry, another option is to place the bottle of canola oil in a warm water bath. This will speed up the thawing process.
How Long Does Canola Oil Last?
Pantry: Unopened canola oil can last for approximately 2 years when stored in a pantry. If no food pantry is available, keep it in a cupboard or any dark place. Once opened, exposing canola oil to oxygen reduces its shelf life down to 1 year.
Fridge: Canola oil can be stored in the refrigerator but may solidify. This does not indicate spoilage; it will liquefy once warmed. Unopened bottles can last 1 to 2 years in the fridge. Opened canola oil stored in the refrigerator has the same 1-year shelf life as oil kept in the pantry.
Freezer: It is not advisable to freeze canola oil as it will solidify and not prolong its shelf life. Storing it in the freezer will maintain its optimal quality for approximately one year.
How To Know When Canola Oil Is Rancid?
One method to determine if your canola oil is fresh is to check the “best by” date on the bottle. However, if the oil has been stored improperly, even before you purchased it, it could be spoiled.
So, to check:
Smell it: A rancid smell indicates that the oil has gone bad. Metallic, bitter, or soapy odors are signs of spoilage that warrant discarding the oil.
Feel it: If you cannot determine its condition by smell, pour a small amount on your finger and observe if it feels tacky or sticky. If it does, it’s best to dispose of the oil.
Look at it: A change in color, such as darkening or the presence of mold, indicates that the canola oil is no longer suitable for use.
Taste it: I know it is super ick, but a small taste of the oil can help assess its condition. Spoiled canola oil may taste slightly sour.
FAQs
Canola oil may solidify, especially at lower temperatures. During winter, you might observe the formation of small wax-like balls in the oil, either floating or settling at the bottom. Rest assured, this is normal, and the oil will return to its liquid state when heated.
The quality of canola oil deteriorates due to exposure to light, heat, and air. To prolong its freshness, opt for a cruet that blocks light. Since cruets are typically placed on counters, ensure they are kept away from direct sunlight and heat-emitting appliances such as stoves and microwaves. Then, it should last 6 months to a year.
Canada is the leading global canola producer, accounting for over 25% of the world’s supply. It also holds the top position in canola exports. The European Union also contributes substantially to canola production.
