Oil, NEVER throw away this part of the cap: it is very important | That’s exactly what it’s for.

1. **Exposure to Air**: Without the seal, your oil is more likely to be exposed to air and oxygen, which accelerates the process of oxidation. This leads to the oil turning rancid faster and losing its fresh flavor and health benefits.

2. **Shortened Shelf Life**: By discarding the seal, you’re shortening the oil’s shelf life, making it more susceptible to spoiling. Some oils, particularly olive oil, are highly sensitive and can degrade quickly without proper protection.

3. **Increased Risk of Contamination**: Without the seal in place, your oil could be more prone to contamination by bacteria, dust, or other elements that can cause spoilage or mold. This can lead to a less safe and enjoyable cooking experience.

### How to Properly Store Oil and Use the Seal

While the seal plays an essential role in maintaining the quality of your oil, proper storage is equally important. Here are some tips for keeping your oil in the best condition:

1. **Store in a Cool, Dark Place**: Oils should be stored away from direct sunlight and heat. A cupboard or pantry is usually the best place to store them, as these conditions help preserve freshness and prevent oxidation.

2. **Keep the Cap On**: After using the oil, always put the cap back on tightly, including the seal if it’s still intact. This minimizes exposure to air and moisture, which can degrade the quality of the oil.

3. **Check the Seal**: If you’re using a bottle of oil that has been sitting for a while, check the seal to make sure it’s intact. If it’s broken or compromised, you may want to consume the oil more quickly to prevent it from spoiling.

### Conclusion: A Simple Trick for Preserving Your Oil

It’s easy to overlook small details in daily life, but the next time you open a bottle of oil, remember the importance of that little plastic part inside the cap. It serves several key functions, from preventing contamination to keeping the oil fresh and maintaining its flavor.

So, **never throw away the seal**. Instead, keep it in place to ensure that your oil stays fresh longer, helping you cook with the highest quality ingredients and enjoy the best possible results in the kitchen!
