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

Ingredients: Mayonnaise made with pasteurized eggs and vinegar tends to have a longer shelf life compared to homemade mayonnaise or products containing raw eggs.
Storage: Proper storage is crucial for extending the shelf life of mayonnaise. Keeping mayonnaise refrigerated at all times is essential to prevent bacterial growth.
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).

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.
