How To Tell If Mayo Is Bad
How can you tell if mayonnaise is bad? In addition to glancing at the expiration date on the packaging, there are a few more ways to tell if mayo has gone bad.
The consistency of mayo should be creamy and not be separated.
So, if your Mayo separates and liquid has collected on top, it’s time to toss it out.
Another thing to look for is a discoloration in the mayo.
The hue changes to a darker yellow or overly brown when it has gone bad.
If the mayo begins to smell sour or excessively sour, you’ll know it’s no longer edible.
If you see mold on or in the mayo, it is time to toss it.
How Long Can Mayonnaise Last?
How Long Does Mayo Last After Opening?
After opening mayo, experts recommend storing it in the fridge. When refrigerating store-bought bottles, the opened product will last 2-3 months.
How Long Does Unopened Mayo Last?
When you buy any product at the store, there is an expiration date printed on the package so that consumers know when the product has expired.
How Long Does Unrefrigerated Mayo Last?
