Understanding Mayonnaise Expiration Date

When it comes to unopened mayonnaise, the expiration date printed on the packaging serves as a guideline for its freshness and quality. However, it's important to note that the expiration date is not a strict deadline but rather an estimation of how long the product will maintain its best quality.

• Quality of Ingredients: The quality of the ingredients used in the mayonnaise can also impact its longevity. Opt for mayonnaise made with fresh, high-quality ingredients for better shelf life.
• Packaging: The type of packaging can also play a role in how long mayonnaise stays fresh. Sealed, airtight containers are ideal for preserving the freshness of the product.

How Long Does Unopened Mayonnaise Last?
