Still Using That Cooking Oil? Here’s How Long It Really Lasts After Opening

How to Store Cooking Oil for Maximum Freshness

Proper storage can extend the life of your oil:

• Keep it cool and dark: Heat, light, and air speed up oxidation. Store oil in a pantry or cupboard away from the stove.
• Seal tightly: Always close the cap tightly after use.
• Use smaller bottles: If you don’t use oil frequently, buy smaller bottles to avoid long-term storage.
• Refrigerate when needed: Certain oils like flaxseed or walnut oil benefit from refrigeration to prevent spoilage.

Tips for Using Oil Safely

• Avoid reusing oil multiple times for deep frying—it degrades faster and produces harmful compounds.
• Label your oils with the opening date to track freshness.
• If an oil smells or tastes off, don’t take risks—throw it away. Cooking with rancid oil can negatively affect both flavor and health.

Final Thoughts

Cooking oil might seem like a pantry staple that lasts forever, but its quality starts to decline the moment you open it. By understanding shelf life, recognizing spoilage signs, and storing oil properly, you can ensure your meals taste fresh and remain safe to eat. A little attention goes a long way in keeping your kitchen both delicious and healthy.
