Does ghee ever spoil or mold, given that it lacks water, and how long can it last unopened versus opened?

Question

Does ghee go bad? Learn about its impressive shelf life and whether it can spoil or grow mold, plus how long you can expect it to last.

Answer 1

Ghee can spoil, though it's less prone to mold due to its low moisture content. Unopened ghee can last 12-18 months, while opened ghee is best used within 3-4 months for optimal flavor and quality.

Detailed Explanation:

While ghee is shelf-stable due to the removal of water during its production, it can still degrade over time. The primary concerns are rancidity and flavor changes. Rancidity occurs when fats break down due to oxidation, leading to an unpleasant taste and smell. Factors like exposure to light, heat, and air accelerate this process.

Here's a breakdown of ghee's shelf life:

1. Unopened Ghee: When stored in a cool, dark place, unopened ghee can typically last for 12 to 18 months from the date of manufacture. Check the 'best by' or 'expiration' date on the packaging for specific guidance.
2. Opened Ghee: Once opened, ghee is best used within 3 to 4 months for the best flavor and quality. While it might still be safe to consume after this period, the taste may become less desirable. Always store opened ghee in an airtight container in a cool, dark place. Refrigeration can extend its shelf life further, but it's not strictly necessary.
3. Signs of Spoilage: Look for changes in color, smell, or taste. Rancid ghee will have a sour or metallic odor and flavor. Discard ghee if you notice any of these signs.

Pro Tip:

Always use a clean, dry spoon when taking ghee from the jar to prevent introducing moisture or contaminants that can accelerate spoilage.
