Best Storage for Olive Oil: Glass, Aluminum, or Plastic?

Best Storage for Olive Oil: Glass, Aluminum, or Plastic?

When it comes to storing olive oil, the choice between plastic, aluminum, or glass containers can significantly impact the oil’s quality over time. Here’s a comparison of each material.

 

    • Glass Bottles (Best Option):
  • Advantages:
• Protects from oxygen: Glass is non-permeable, so it prevents oxygen from seeping in, which can cause the oil to oxidize and spoil.
• Preserves flavor: It doesn’t affect the flavor of the olive oil, keeping it as pure as possible.
• Light protection: Dark glass bottles (e.g., green or amber) block harmful UV rays, which can degrade olive oil and reduce its antioxidant properties.
  • Disadvantages: Glass is breakable, so it requires careful handling.

    • Aluminum or Tin Cans:
  • Advantages:
• Blocks light: Like dark glass, aluminum or tin cans provide excellent protection against light, preserving the quality of olive oil.
• Durable: These containers are lightweight and shatterproof, making them easy to store and handle.
• Recyclable: Aluminum is recyclable, making it an eco-friendly option.
  •  Disadvantages:

Aluminum can react with the oil if the interior is not properly coated, though most modern containers have protective linings to prevent this.

    • Plastic Bottles (Least Ideal):

 

  •  Advantages:

• Lightweight and unbreakable: Plastic is easy to transport and won’t shatter.
• Cost-effective: It is often cheaper to produce and ship plastic bottles.

  • Disadvantages:

• Permeable to oxygen: Over time, oxygen can seep into plastic containers, causing the oil to oxidize and go rancid.
• Chemical leaching: Certain types of plastic can leach chemicals into the oil, especially if exposed to heat or sunlight.
• Doesn’t block light: Unless dark in color, plastic bottles do not protect well against UV rays.


Glass (especially dark-colored) and aluminum are both excellent choices for preserving olive oil. They protect against light and oxygen, both of which can degrade the oil’s quality over time. Plastic is the least ideal option, as it can lead to oxidation and chemical contamination. Therefore, dark glass bottles or aluminum cans are the best for long-term storage of olive oil.
