How to store Olive Oil

olive oil

Olive oil. Who doesn’t love it? whether it be drizzled over a summer salad, your go to substitute for butter or spreads, or a fundamental ingredient to your favourite dressing (mixed with lemon juice- YUM). You can always count on it and it can always rely on you. Today I want to share with you the best way to store our favourite golden oil in a bid to maximise it’s health benefits. How do you do it? Everything you need to know is right here.

Every time olive oil is exposed to air and/or light, the saturated fats found in the oil undergo oxidation. Oxidation means the fats in the oil become unstable and hence, can damage your health.

How does this happen? Olive oil contains chlorophyll and when chlorophyll is exposed to air and/or light it accelerates decomposition of the oil and makes the oil go rancid rather quickly.

How do we avoid it? If you’re like most people, you’re probably leaving your bottle of olive oil right on the counter (or worse, next to the stove), opening and closing it multiple times a week? This is the fastest way to ensure your bottle’s shelf life is going to deplete rapidly. To ensure your olive oil lasts the distance, my top four tips are as follows:

  • Keep your bottle in a cool, dark place
  • Purchase smaller bottles rather than larger to ensure freshness.
  • Ensure the packaging is made up of dark coloured glass to help protect the oil from extra light
  • Immediately replace the cap (firmly) after each use
