The impact of heat and light exposure on Olive Oil quality

Olive oil, especially extra virgin olive oil (EVOO), is renowned for its rich flavor and numerous health benefits. However, its quality and shelf life are highly susceptible to environmental factors, particularly heat and light. For consumers in the United Arab Emirates (UAE), where high temperatures and intense sunlight are prevalent, understanding these effects is crucial to preserving the oil’s integrity.

The effects of heat on olive oil

Exposure to elevated temperatures accelerates the degradation of olive oil. High heat can initiate oxidation, leading to the breakdown of beneficial compounds such as polyphenols and antioxidants. This process not only diminishes the oil’s nutritional value but also alters its flavor profile, often resulting in a rancid taste.

In the UAE, where ambient temperatures can soar, it’s imperative to store olive oil in a cool environment. Keeping olive oil away from heat sources like stovetops or direct sunlight can significantly prolong its freshness and maintain its healthful properties.

The impact of light exposure on olive oil

Light, particularly ultraviolet (UV) radiation, can adversely affect olive oil by triggering photo-oxidation. This reaction degrades chlorophyll and other sensitive compounds, leading to a loss of antioxidants and the development of off-flavors. Studies have shown that oils stored in light-exposed conditions exhibit a substantial reduction in tocopherol (vitamin E) content and an increase in rancidity compared to those kept in the dark.

To mitigate light-induced deterioration, it’s advisable to choose olive oils packaged in dark-colored or opaque containers. Additionally, storing the oil in a dark cupboard or pantry further shields it from harmful light exposure.

Best practices for storing olive oil in the UAE

Given the UAE’s climatic conditions, consumers should adopt the following storage practices to preserve olive oil quality:

• Temperature Control: Store olive oil at temperatures between 13°C and 25°C. Avoid placing it near heat-emitting appliances or in areas with fluctuating temperatures.

• Light Protection: Use dark glass bottles or stainless steel containers to protect the oil from light. Ensure the storage area is away from direct sunlight and artificial light sources.

• Seal Integrity: Keep the bottle tightly sealed when not in use to prevent oxidation from air exposure.

• Purchase Quantities: Buy olive oil in quantities that can be consumed within a few months to ensure consistent freshness.
