Proper oil storage: Keep cold-pressed oils refrigerated
Oil is a staple in every kitchen, but are we sure we’re storing it properly? It seems straightforward: keep it on a shelf or in a cabinet and use it as needed. However, some types of oil require special storage to preserve their taste and quality, which can quickly deteriorate if they aren't kept under the right conditions.

We often overlook whether we're storing oils correctly, yet their quality and freshness greatly affect the taste of our dishes. Improper storage can lead to quicker oxidation of the oil, causing it to lose its nutritional value and possibly develop a bitter taste.
Which oils should be kept in the refrigerator?
Not all oils require the same storage temperature. While most of us keep vegetable oil on the kitchen counter or in a cabinet, some oils are best stored in the refrigerator to maintain their freshness and beneficial properties. Examples include cold-pressed oils, such as flaxseed, evening primrose, and walnut oil. These oils are susceptible to light and temperature, and storing them in warm conditions can cause them to spoil quickly.
Flaxseed oil, known for its health benefits, should always be refrigerated. It is rich in unsaturated fatty acids, which are prone to oxidation. Exposure to light and heat can cause it to lose its nutritional value and even alter its taste. The same is true for other cold-pressed oils; their delicate structure requires cooling to maintain freshness for longer.
Which oils can be kept outside the refrigerator?
Canola oil, sunflower oil, and olive oil are more stable and can be stored at room temperature, provided they are kept away from direct sunlight. To protect them from oxidation, they should be stored in dark, airtight containers. Although olive oil is relatively durable, it's advisable to avoid long-term exposure to warmth; it’s best stored in a cool, dark place.
Oil components, such as fatty acids and vitamins, are sensitive to light and air exposure. Therefore, we should always ensure the bottle is well-sealed after use to preserve quality and long-term health benefits.
Why is it important to know how to store oils?
Proper storage of oils is crucial for maintaining their quality and taste. Poorly stored oil can quickly lose its properties and even taste bitter. Cold-pressed oils, rich in valuable omega-3 fatty acids, are susceptible and require refrigeration to maintain their full flavor and health benefits.
If we've been storing all our oils in one place, it might be worth reconsidering and moving some of them to the refrigerator. This way, we can extend their freshness and achieve better results in the kitchen.
