Olive Oil Shelf Life: When Does It Go Bad?

Have you ever wondered what impacts olive oil shelf life? Like any other food product, olive oil has a lifespan. Understanding why and when it goes bad is essential for maintaining its quality.

In this blog post, we look at olive oil shelf life and explore factors that impact its longevity.

Understanding Olive Oil Shelf Life

Olive oil is a beloved ingredient in many kitchens. It is cherished for its exquisite flavor and numerous nutritional capacities.

A shelf life refers to the time during which a product, in this case, olive oil, can be stored without major deterioration in quality, flavor, and safety.

One key factor impacting olive oil is oxidation. This occurs when the oil is exposed to air. Oxygen affects the fats and antioxidants in the oil, leading to its chemical structure denaturing. The result is off-flavors and odors.

Other factors include exposure to light, heat, and moisture, which can accelerate the oxidation process.


Signs of Olive Oil Going Bad

Here is what to look out for:

Rancidity: Recognizing the smell and taste of rancid olive oil

Rancid olive oil has a distinctly unpleasant odor and taste. Instead of the fresh, fruity aroma, rancid olive oil smells stale or musty.

Changes in appearance: Cloudiness or sediment in the bottle

When olive oil starts to spoil, it changes in appearance. One noticeable difference is the development of cloudiness.

Fresh olive oil is typically clear and transparent, but it may become murky as it deteriorates. Additionally, sediment or particles may be present at the bottom of the bottle.

Other indicators: Mold growth or off-putting flavors

Mold growth on the oil’s surface or inside the bottle is a clear indication of spoilage and should be a cause for concern.

Furthermore, it is likely past its prime if the olive oil has acquired off-putting flavors such as a vinegary or soapy taste.

Factors Affecting Olive Oil Shelf Life

  • The quality of olive oil plays a significant role in its shelf life, with extra virgin olive oil generally having a shorter shelf life than refined olive oil.
  • Exposure to light, heat, and air can accelerate the deterioration of olive oil, causing it to go rancid more quickly, so storing it in a cool, dark place away from direct sunlight and heat sources is essential.
  • Choosing proper storage containers and techniques, such as using dark-colored glass bottles or metal containers that block out light and employing airtight seals, can help extend the shelf life of olive oil by reducing its exposure to oxygen and light.


Extending Shelf Life of Olive Oil

Here are a few notes and tips for extending the shelf life of olive oil:

  • Store olive oil in a cool, dark place.
  • Use opaque or dark-colored bottles to minimize light exposure. Our range of oils is packed in a black bottle for this reason.
  • Avoiding excessive heat or temperature fluctuations
  • Sealing the bottle tightly to prevent air contact.
