How Long Can Mayonnaise Be Kept in the Fridge?

Mayonnaise is a popular condiment known for its creamy texture and tangy flavor. Whether you use it as a sandwich spread, salad dressing, or dip, proper storage is essential to maintain its quality and safety. In this blog post, we will explore how long mayonnaise can be kept in the fridge, tips for storing it correctly, and signs of spoilage to watch out for.

Understanding Mayonnaise Shelf Life

Mayonnaise is typically made from ingredients such as eggs, oil, vinegar, and seasonings. Due to its high acidity and oil content, commercial mayonnaise is less prone to bacterial growth compared to other perishable foods. However, once opened, it is important to refrigerate mayonnaise to prevent spoilage.

Unopened Mayonnaise

Unopened jars or bottles of mayonnaise can typically last for 1-2 months beyond the "Best By" date if stored in a cool, dark place like the pantry. However, refrigerating it will extend its shelf life significantly.

Opened Mayonnaise

Once opened, mayonnaise should be stored in the refrigerator at all times.
Opened mayonnaise can retain its quality for 2-3 months after opening if properly refrigerated.
It is crucial to follow proper storage guidelines to ensure the safety and freshness of the mayonnaise.

Proper Storage Tips for Mayonnaise

To maximize the shelf life of mayonnaise and maintain its quality, follow these practical storage tips:

Refrigeration

Always refrigerate mayonnaise after opening to slow down bacterial growth and maintain its flavor.
Store mayonnaise in the main compartment of the refrigerator, not in the door where temperatures fluctuate more.

Seal Properly

Ensure the lid or cap of the mayonnaise jar is tightly sealed after each use to prevent air exposure and contamination.

Cross-Contamination

Use clean utensils when scooping out mayonnaise to prevent introducing bacteria into the jar.

Check for Spoilage

Discard mayonnaise if you notice any changes in color, texture, or odor, as these are signs of spoilage.

Signs of Spoiled Mayonnaise

It is essential to be able to identify signs of spoiled mayonnaise to prevent foodborne illnesses. Here are some indicators that your mayonnaise may have gone bad:

Mold Growth

If you see any mold on the surface of the mayonnaise, discard it immediately.

Off Odor

Spoiled mayonnaise may have a sour, rancid, or off-putting odor. If it smells unpleasant, it is best to throw it away.

Change in Texture

If the mayonnaise becomes excessively watery, curdled, or separated, it is a sign of spoilage.

Expiration Date

Always check the expiration date on the mayonnaise packaging. If it has expired, it is safer to discard it.

Conclusion

In conclusion, mayonnaise can be safely stored in the refrigerator for an extended period if proper storage practices are followed. By refrigerating opened mayonnaise, sealing it tightly, and being vigilant for signs of spoilage, you can enjoy this versatile condiment without compromising your health. Remember to always practice good food safety habits to ensure the quality and freshness of your favorite foods.
