As one of the healthiest and most versatile oils in the world, extra virgin olive oil (EVOO) has become a staple in many kitchens. From cooking and baking to making salad dressings and marinades, EVOO is a popular choice due to its rich flavor and numerous health benefits. However, to preserve its quality and nutritional value, it’s essential to store EVOO properly. One of the most critical aspects of storing EVOO is the type of container used, with many experts recommending dark containers. But does extra virgin olive oil really need to be in a dark container? In this article, we’ll delve into the world of EVOO storage and explore the importance of dark containers in maintaining the quality and freshness of this beloved oil.
Understanding the Science Behind EVOO Degradation
Before we dive into the specifics of storage containers, it’s crucial to understand the factors that contribute to EVOO degradation. Light, heat, and oxygen are the primary enemies of EVOO, as they can cause the oil to become rancid, lose its flavor and aroma, and decrease its nutritional value. When EVOO is exposed to light, especially direct sunlight or artificial lighting, it can undergo a process called photooxidation. This reaction leads to the formation of off-flavors, off-odors, and potentially harmful compounds. Similarly, heat can accelerate the oxidation process, while oxygen can react with the oil’s polyphenols, causing them to break down and lose their antioxidant properties.
The Role of Light in EVOO Degradation
Light is a significant factor in EVOO degradation, and it’s essential to understand how different types of light affect the oil. UV rays, in particular, are highly damaging to EVOO, as they can penetrate deep into the oil and cause photooxidation. Even indirect sunlight or diffused light can contribute to EVOO degradation, although the effects may be less pronounced. To mitigate the impact of light, it’s recommended to store EVOO in a dark or low-light environment.
Types of Containers and Their Effects on EVOO
