How Long Can Fresh Mayonnaise Stay Perishable- A Guide to Storage and Shelf Life

How Long Can You Keep Fresh Mayonnaise?

Mayonnaise is a staple in many kitchens, used in a variety of dishes from salads to sandwiches. However, one common question that often arises is: how long can you keep fresh mayonnaise? The answer depends on several factors, including how it was stored and whether it has been opened or not. In this article, we will explore the shelf life of fresh mayonnaise and provide tips on how to extend its freshness.

Unopened Mayonnaise

If you have an unopened jar of mayonnaise, it typically has a long shelf life. Most commercially produced mayonnaise has a “best by” or “sell by” date on the label, which can range from several months to over a year. However, it’s important to note that these dates are not an expiration date, but rather a guideline for quality. In general, unopened mayonnaise can be kept in the refrigerator for up to 6-12 months from the date of manufacture.

Opened Mayonnaise

Once you open a jar of mayonnaise, its shelf life begins to diminish. After opening, it’s important to store the mayonnaise in the refrigerator to maintain its freshness. According to the U.S. Food and Drug Administration (FDA), opened mayonnaise can be kept in the refrigerator for up to 2-3 weeks. However, if you notice any changes in color, texture, or smell, it’s best to discard the product.

Extending the Shelf Life of Mayonnaise

To help extend the shelf life of fresh mayonnaise, follow these tips:

1. Store it properly: Always keep mayonnaise in the refrigerator at or below 40°F (4°C) to slow down bacterial growth.
2. Use a clean spoon: When scooping out mayonnaise, use a clean spoon to prevent contamination.
3. Avoid exposure to heat: Keep mayonnaise away from hot surfaces and avoid leaving it out at room temperature for extended periods.
4. Use it within a reasonable time: If you have a large jar of mayonnaise, try to use it within a few weeks to ensure its quality.

Conclusion

In conclusion, the shelf life of fresh mayonnaise can vary depending on whether it’s unopened or opened. Unopened mayonnaise can be stored in the refrigerator for up to 6-12 months, while opened mayonnaise should be consumed within 2-3 weeks. By following proper storage and usage guidelines, you can enjoy fresh mayonnaise for longer periods. Always keep an eye on its quality and discard it if you notice any signs of spoilage.
