The Correct Way To Store Cold Pressed Oils
Cold pressed oils have gained immense popularity among health-conscious consumers for their nutritional benefits and pure, unadulterated flavors. Extracted through mechanical means without the use of high heat or chemical treatments, these oils retain more nutrients and antioxidants than refined oils. Proper storage is key to maintaining their quality and extending their shelf life. Here's how you can keep your cold pressed cooking oils fresh and flavorful:
- Impact of Temperature and Light
Cold pressed oils are particularly sensitive to warmth and sunlight, which can accelerate their degradation. This exposure can cause the oils to oxidise, lose their nutritional value, and turn rancid more quickly. Avoid placing them near heat sources such as the stove, oven, or windows that receive direct sunlight. Ideally, store your oils in a cool and dark cupboard.
- Minimise Exposure to Air
Exposure to air can also speed up the oxidation process of cold pressed oils. Always ensure the container is sealed tightly after each use. Leaving the bottle open for extended periods allows air to interact with the oil, reducing its shelf life and quality. If you purchase oil in large quantities, it's recommended to transfer a smaller amount into a separate container for daily use to keep the rest fresher for longer. However, since cold pressed oils should be consumed fresh, consider buying smaller quantities that you can use up faster.
- Refrigeration: Yes or No?
While refrigerating certain cold pressed oils, like flaxseed or walnut oil, can extend their shelf life, other oils may solidify or become cloudy in cooler temperatures. This is normal and doesn’t affect their quality. Simply leave the oil at room temperature for about 30-40 minutes before use, and it will return to its normal consistency and flavor.
- Regularly Check for Freshness
Regularly check the smell and taste of your cold pressed oils, as they typically have a shorter shelf life compared to refined oils. They are unrefined and contain natural nutrients that can degrade over time. Always check the expiry date on the bottle and aim to use the oil within the recommended time frame. Cold-pressed oils generally have a shelf life of about 6 months to 1 year. After this time, the oil may start to lose its flavor and nutrients. Any signs of bitterness or a sharp, unpleasant aroma can indicate rancidity. If an oil smells or tastes off, it’s best to discard it, as rancid oils can contain harmful free radicals.
By following these simple storage tips, you can ensure that your cold pressed cooking oils retain their optimal flavor, nutritional value, and freshness for as long as possible. Enjoy the full benefits of these wonderful oils in your cooking by treating them with a little care and attention in how you store them.
