Does Light Exposure Really Affect the Health Benefits of Greek Extra Virgin Olive Oil?

For years, the debate over how best to store Greek Extra Virgin Olive Oil (EVOO) has centered around one key question: does exposure to light degrade its health benefits? Many consumers are concerned that clear glass bottles might compromise the oil's quality, while others believe the vibrant green color of fresh olive oil should be showcased. But what does the science actually say?

The Science Behind Light Exposure and Greek Extra Virgin Olive Oil

Several studies have examined the effects of light exposure on Greek Extra Virgin Olive Oil, primarily focusing on its chemical composition over time. Research published in Food Analytical Methods and the European Food Research and Technology journal indicates that prolonged exposure to light can lead to a reduction in certain compounds, including chlorophyll, carotenoids, and tocopherols (vitamin E). These compounds contribute to Greek Extra Virgin Olive Oils antioxidant properties, which are often associated with its health benefits.

However, what these studies do not conclusively prove is that light exposure directly eliminates or significantly reduces the core health benefits of high-phenolic Greek Extra Virgin Olive Oil. While some chemical changes do occur, the presence of beneficial polyphenols—such as oleocanthal and oleacein, known for their anti-inflammatory and antioxidant effects—remains largely intact within reasonable storage durations.

What This Means for Consumers

1. Quality vs. Health Benefits: While light exposure may alter the sensory characteristics of Greek Extra Virgin Olive Oil(such as its color and aroma) and reduce the levels of some antioxidants, there is no direct evidence that it renders the oil ineffective in terms of health benefits.
2. Proper Storage Matters: The real culprit behind Greek Extra Virgin Olive Oil degradation is not just light, but a combination of light, heat, and oxygen. Storing your oil in a cool, dark place and sealing it properly is far more crucial than whether the bottle is clear or dark.
3. Retail vs. Direct Sales: At Ilias and Sons, we offer both clear and green glass bottle options. For online sales and direct-to-consumer events, clear glass bottles allow customers to appreciate the rich, green hue of freshly harvested Greek Extra Virgin Olive Oil. However, for retail shelves where exposure to store lighting is prolonged, we provide green glass bottles to help maintain long-term quality.

At Ilias and Sons, we offer both clear and green-tinted glass options, allowing customers to choose based on their preference and intended storage conditions. Regardless of packaging, proper storage remains key to preserving the oil’s freshness and nutritional benefits.

The debate continues, but one thing remains clear: Greek Extra Virgin Olive Oil, regardless of its packaging, remains a powerhouse of health benefits when stored correctly. So whether it’s in a dark or clear bottle, the key is how you handle and store your oil after purchase.
