The Shelf Life of Mayonnaise: Everything You Need to Know

Mayonnaise is a popular condiment that adds creaminess and flavor to a variety of dishes, from sandwiches to salads. However, like all perishable foods, mayonnaise has a limited shelf life. Understanding how long mayonnaise lasts and how to properly store it is key to maintaining food safety and quality. In this comprehensive guide, we will explore everything you need to know about the shelf life of mayonnaise.

How Long Does Mayonnaise Last?

Mayonnaise typically has a shelf life of about 2 to 3 months when stored in the refrigerator. However, the shelf life can vary depending on several factors, including the brand of mayonnaise, the ingredients used, and how it is stored. Here are some key points to consider:

Factors Affecting Mayonnaise Shelf Life

1. Ingredients: Mayonnaise made with pasteurized eggs and vinegar tends to have a longer shelf life compared to homemade mayonnaise or products containing raw eggs.

2. Storage: Proper storage is crucial for extending the shelf life of mayonnaise. Keeping mayonnaise refrigerated at all times is essential to prevent bacterial growth.

3. Contamination: Avoid cross-contamination by using clean utensils when scooping out mayonnaise to prevent introducing bacteria into the jar.

How to Store Mayonnaise Properly

Proper storage is key to maintaining the quality and safety of mayonnaise. Follow these tips to ensure your mayonnaise stays fresh for as long as possible:

Refrigeration

• Store mayonnaise in the refrigerator at a temperature below 40°F (4°C).
• Keep the mayonnaise tightly sealed when not in use to prevent air and bacteria from entering the container.
• Avoid storing mayonnaise in the refrigerator door as temperature fluctuations can impact its shelf life.

Avoiding Contamination

• Use clean utensils to scoop out mayonnaise, and never double-dip to prevent cross-contamination.
• Make sure to wipe the jar's rim clean after each use to prevent the buildup of residue that can harbor bacteria.

Check for Signs of Spoilage

• Discard mayonnaise if you notice any changes in color, texture, or odor. Mold growth is a clear indication that the mayonnaise has spoiled and should be thrown away.

Tips for Extending Mayonnaise Shelf Life

While mayonnaise does have a limited shelf life, there are a few tips and tricks you can use to extend its freshness:

1. Use a Clean Utensil: Always use a clean spoon or knife to scoop out mayonnaise to prevent introducing bacteria into the jar.

2. Keep it Sealed: Make sure the jar is tightly sealed after each use to prevent air exposure, which can lead to oxidation and spoilage.

3. Store it Properly: Keep mayonnaise refrigerated at all times and avoid leaving it out at room temperature for extended periods.
