How Long Does Mayo Last Past Best-By? | Savory Secrets

Mayo can last up to 3 months past its best-by date if stored properly in the fridge.

The Basics of Mayonnaise Shelf Life

Mayonnaise is a popular condiment, beloved for its creamy texture and rich flavor. However, like many food products, it has a shelf life that consumers need to understand. The “best-by” date on the jar is often misunderstood. It’s not an expiration date but rather a guideline for peak quality. After this date, the mayo may still be safe to consume if it has been stored correctly.

Understanding how long mayo lasts past its best-by date involves several factors, including storage conditions and whether the jar has been opened or remains sealed. Generally, unopened mayo can last much longer than opened mayo due to exposure to air and potential contamination.

Factors Affecting Mayonnaise Longevity

Several factors influence how long mayonnaise lasts beyond its best-by date:

Storage Conditions

Mayo should always be stored in a cool, dry place. Once opened, it must be refrigerated immediately to slow down bacterial growth. Keeping it in the door of the refrigerator is common but not ideal; the temperature fluctuates more there. Instead, store it on a shelf where temperatures remain consistent.

Type of Mayonnaise

Different types of mayonnaise have varying shelf lives. Homemade mayonnaise lacks preservatives and typically lasts only about one week in the fridge. Commercially produced mayonnaise contains preservatives that extend its shelf life significantly.

Packaging Integrity

If the seal on an unopened jar is broken or damaged, this can compromise the mayo’s longevity. Always check for any signs of spoilage when opening a new jar.

How Long Does Mayo Last Past Best-By?

For unopened jars of mayonnaise, you can expect them to last up to three months past the best-by date if stored properly in the refrigerator. Once opened, however, things change slightly. Opened mayo can typically last about 2-3 months past its best-by date when kept consistently refrigerated.

Here’s a breakdown:

Condition	Timeframe Past Best-By Date	Storage Tips
Unopened Jar	Up to 3 months	Store in fridge; avoid heat sources.
Opened Jar	2-3 months	Tightly seal and refrigerate immediately.
Homemade Mayo	1 week max	Keeps in fridge; use clean utensils.

It’s essential to know how to identify spoiled mayonnaise to avoid foodborne illness. Here are some telltale signs:

Smell Test

Fresh mayo has a mild aroma. If it smells sour or off, it’s time to toss it out.
