Factors affecting the quality of olive oil
Light: Olive oil is very sensitive to light and prolonged exposure to light accelerates the oxidization process, leading to a reduction in quality. Therefore, the use of dark-colored bottles (e.g. brown or dark green) can effectively block ultraviolet and visible light, reducing oxidation and preserving the freshness and nutritional value of the oil.
Temperature effects: Temperature is essential for the preservation of olive oil. Higher temperatures accelerate the rate of oxidation and deterioration of olive oil, while lower temperatures help to maintain its quality. It is recommended to store olive oil in a cool, dry place, at an optimal temperature of 15-25°C.
Air: Olive oil reacts easily with oxygen, leading to oxidation and deterioration. For this reason, it is important to ensure that containers are well sealed when storing to avoid air entry.
What are the common colors of olive oil bottles?
Dark green bottles: dark green bottles effectively block blue light and reduce the oxidizing effect of light on olive oil. At the same time, the dark green color gives a fresh and natural feeling visually, which is suitable for olive oil brands that emphasize naturalness and health.
Brown bottles: brown is the most common color of olive oil glass bottles, with the advantage of blocking ultraviolet rays and reducing the oxidizing effect of light on the olive oil. In addition, brown glass bottles have high chemical stability and do not easily react with the olive oil, keeping it pure.
Transparent glass bottles: although transparent glass bottles allow consumers to see the color and texture of the olive oil clearly, they are not commonly used for the packaging of high-quality olive oil due to the fact that olive oil is sensitive to light, and prolonged exposure to light can lead to a deterioration of its quality.
Why olive oil should be stored in dark-colored bottles?
The main reason for storing olive oil in dark colored bottles is to protect the oil from oxidation and deterioration due to light. Here are some specific reasons for this:
Blocking ultraviolet rays: dark colored bottles, especially green, brown, or amber ones, are effective in blocking ultraviolet rays. UV rays can accelerate the oxidation of the fatty acids in olive oil, leading to a deterioration in the quality of the oil and the production of undesirable odors and flavors.
Reducing the effects of light: light promotes chemical reactions in olive oil, leading to a reduction in the flavor, aroma, and nutritional value of the oil. Dark-colored bottles can reduce the effects of light on the oil, maintaining its original qualities.
Extended shelf life: by reducing the oxidization process, dark bottles help to extend the shelf life of the oil, keeping it fresher for a longer period of time during storage.
Maintains quality stability: Olive oil stored in an environment protected from light is more stable and does not suffer from fluctuations in quality due to changes in light conditions.
Protection of nutrients: Olive oil is rich in antioxidants and vitamin E, nutrients that break down easily when exposed to light. Dark-colored bottles help to protect these nutrients from being destroyed.
Market tradition: In the traditional market for olive oil, dark bottles have become a standard way of packaging, and consumers usually think that olive oil in dark bottles is of better quality.
Therefore, in order to ensure that the quality of olive oil is not compromised during transportation and storage, olive oil producers usually choose dark-colored bottles for packaging olive oil. In addition, besides the color, the sealing of the bottle is also an important factor in protecting the quality of the olive oil.

Why don't use plastic bottles for olive oil?
Chemical penetration: plastic bottles may release chemicals that can penetrate the olive oil and affect its flavor and safety. In particular, certain types of plastic, such as those containing bisphenol A (BPA), may react with oil-based substances.
Oxygen penetration: plastic bottles are usually more permeable than glass bottles, which means that oxygen can penetrate the bottle more easily, leading to the oxidation of the olive oil, thus reducing its quality and nutritional value.
Light penetration: although some plastic bottles can be dark in color, the plastic itself cannot block out light as completely as glass. Light can promote the oxidization process of the oil, therefore plastic bottles are not as good as glass bottles in protecting the oil from light.
Environmental issues: Plastic bottles have a greater impact on the environment as they do not degrade easily and may cause long-term environmental pollution. In contrast, glass bottles are more environmentally friendly, reusable, and easier to recycle.
Impression of quality: Consumers usually perceive olive oil in glass bottles as being of higher quality, whereas plastic bottles may give the impression of being of lower quality or cheaper.
Durability: glass bottles are more durable and less prone to deformation than plastic bottles, which is an advantage for long-term storage of olive oil.
Temperature sensitivity: plastic bottles are more sensitive to changes in temperature and high temperatures may cause them to deform or release more chemicals, whereas glass bottles are more stable.
