Mayonnaise, a creamy and versatile condiment, is a staple in many kitchens around the world. Whether you use it to dress up a sandwich, add richness to a salad, or as a base for a delicious dip, mayonnaise is a go-to ingredient for many dishes. However, like all perishable foods, mayonnaise does come with an expiration date. In this blog post, we'll delve into the truth about expiration dates on mayonnaise, how to properly store it, and when it's time to toss it out.

Understanding Expiration Dates

What Do Expiration Dates Mean?

• "Best By" Date: This date indicates the quality of the product, and consuming it after this date may result in a decline in taste or texture.
• "Use By" Date: This date is more critical for perishable foods and indicates when the product may no longer be safe to consume.
• "Sell By" Date: This date is used by retailers for inventory management and doesn't necessarily mean the product is unsafe to eat.

Decoding Expiration Dates on Mayonnaise

• Mayonnaise typically has a shelf life of around 2-3 months after opening.
• The expiration date on mayonnaise is usually a "Best By" date, focusing on quality rather than safety.
• The high acid content in mayonnaise helps to inhibit bacterial growth, but it can still spoil over time.

Proper Storage of Mayonnaise

Refrigeration Is Key

• Store mayonnaise in the refrigerator at all times.
• Keep it away from light and heat to maintain its quality.
• Check the temperature of your fridge to ensure it's below 40°F (4°C).

Tips for Safe Storage

• Always seal the lid tightly after each use to prevent bacteria from getting in.
• Avoid cross-contamination by using clean utensils when scooping out mayonnaise.
• Don't leave mayonnaise at room temperature for extended periods, especially in hot weather.

Signs of Spoiled Mayonnaise

How to Tell If Your Mayonnaise Has Gone Bad

• Change in Color: If your mayonnaise has darkened or developed a yellow or green tint, it's a sign of spoilage.
• Unpleasant Odor: Spoiled mayonnaise may have a rancid or sour smell.
• Texture Changes: If the texture becomes watery or lumpy, it's time to discard it.

Safety First

• Consuming spoiled mayonnaise can lead to food poisoning, so it's crucial to err on the side of caution.
