Mayonnaise, a staple condiment in many households, is often a topic of discussion when it comes to its shelf life. While mayonnaise can last for several months when stored properly, its longevity once opened is a different story. In this article, we’ll delve into the world of mayonnaise and explore how long it will last once opened, as well as provide some valuable tips on how to store it, identify spoilage, and make the most of this tasty condiment.
Unopened Mayonnaise: A Long Shelf Life
Unopened mayonnaise, when stored in a cool, dry place, can last for a significant amount of time. The exact shelf life will depend on the brand, type, and storage conditions, but generally speaking, unopened mayonnaise can last for:
- 12 to 18 months at room temperature (68°F to 72°F or 20°C to 22°C)
- 2 to 3 years in the refrigerator (39°F to 40°F or 4°C to 4°C)
- Up to 5 years in the freezer (-18°C or 0°F)
It’s essential to check the expiration date or “best by” date on the jar, as this will give you a better idea of the mayonnaise’s shelf life. However, even if the expiration date has passed, the mayonnaise may still be safe to consume if it has been stored properly.
Factors Affecting Shelf Life
Several factors can affect the shelf life of mayonnaise, including:
- Storage conditions: Direct sunlight, high temperatures, and humidity can cause mayonnaise to spoil faster.
- Quality of ingredients: Low-quality ingredients or preservatives can affect the mayonnaise’s stability and shelf life.
- Manufacturing process: The way mayonnaise is manufactured can impact its shelf life. For example, some brands may use a higher acidity level to extend the shelf life.
Opened Mayonnaise: A Shorter Shelf Life
Once mayonnaise is opened, its shelf life shortens significantly. This is because the jar is no longer sealed, allowing contaminants like bacteria, yeast, and mold to enter the jar and cause spoilage. Generally, opened mayonnaise can last for:
- 3 to 6 months in the refrigerator (39°F to 40°F or 4°C to 4°C)
- 1 to 2 months at room temperature (68°F to 72°F or 20°C to 22°C)
It’s crucial to store opened mayonnaise in the refrigerator to slow down the spoilage process. You can also consider freezing it to extend its shelf life.
Signs of Spoilage
When mayonnaise goes bad, it can exhibit some obvious signs of spoilage, including:
- Off smell: Mayonnaise that has gone bad may have a strong, unpleasant odor.
- Slimy or moldy texture: Check for any visible signs of mold or a slimy texture on the surface or around the edges of the mayonnaise.
- Slippery or separated texture: Fresh mayonnaise should have a smooth, creamy texture. If it’s slippery or separated, it may be past its prime.
- Taste or flavor changes: If the mayonnaise tastes sour, bitter, or unpleasantly different, it’s likely gone bad.
Storing Mayonnaise: Tips and Tricks
To get the most out of your mayonnaise and extend its shelf life, follow these storage tips and tricks:
- Refrigerate opened mayonnaise: Store opened mayonnaise in the refrigerator at a consistent temperature below 40°F (4°C).
- Use a clean utensil: When scooping out mayonnaise, use a clean utensil to avoid contaminating the jar.
- Keep it airtight: Use plastic wrap or aluminum foil to cover the jar and prevent air from entering.
- Freeze it: If you don’t plan to use the mayonnaise within a few months, consider freezing it to extend its shelf life.
- <strong Label and date the jar: Keep track of when you opened the jar and label it with the date to ensure you use the oldest mayonnaise first.
Freezing Mayonnaise: A Game-Changer
Freezing mayonnaise is an excellent way to extend its shelf life. When frozen, mayonnaise can last for up to 6 months. Here are some tips for freezing mayonnaise:
- Transfer to an airtight container: Transfer the mayonnaise to an airtight container or freezer bag to prevent freezer burn.
- Label and date the container: Be sure to label the container with the date and contents.
- Store in the coldest part of the freezer: Place the container in the coldest part of the freezer to maintain a consistent temperature.
Making the Most of Mayonnaise
Mayonnaise is a versatile condiment that can be used in a variety of dishes, from sandwiches to salads, dips, and sauces. To get the most out of your mayonnaise, try these recipes and ideas:
- Homemade mayonnaise: Make your own mayonnaise at home using eggs, oil, and vinegar or lemon juice.
- Mayo-based sauces: Use mayonnaise as a base for sauces like ranch, tartar, or Thousand Island dressing.
- Dips and spreads: Mix mayonnaise with herbs, spices, and other ingredients to create delicious dips and spreads.

What is the shelf life of unopened mayonnaise?
Unopened mayonnaise can last for a long time if stored properly. The typical shelf life of unopened mayonnaise is 12 to 18 months from the manufacturing date. However, it’s not uncommon for unopened mayonnaise to remain safe and fresh for up to two years or more if stored in a cool, dry place, away from direct sunlight and heat sources.
It’s essential to check the “Best By” or “Best If Used By” date on the label to determine the recommended shelf life. Keep in mind that mayonnaise may still be safe to consume after this date, but its quality and texture may start to degrade. Always store unopened mayonnaise in its original container, tightly sealed, and away from strong-smelling foods, as mayonnaise can absorb odors easily.
How long does opened mayonnaise last in the fridge?
Opened mayonnaise can last for several months in the fridge, but its shelf life is significantly shorter than unopened mayonnaise. Generally, opened mayonnaise can last for two to three months in the fridge, provided it’s stored properly. It’s crucial to keep the opened mayonnaise in an airtight container, such as a glass jar with a tight-fitting lid, to prevent contamination and spoilage.
When storing opened mayonnaise in the fridge, make sure to keep it at a consistent refrigerator temperature below 40°F (4°C). You should also check the mayonnaise regularly for signs of spoilage, such as an off smell, slimy texture, or mold growth. If you notice any of these signs, it’s best to discard the mayonnaise to avoid foodborne illness.
Can I freeze mayonnaise?
Yes, you can freeze mayonnaise, but it’s essential to do so correctly to maintain its quality and texture. Mayonnaise can be frozen for up to six months, but it’s best to use it within three to four months for optimal flavor and texture. When freezing mayonnaise, transfer it to an airtight container or freezer-safe bag, removing as much air as possible before sealing.
When you’re ready to use frozen mayonnaise, simply thaw it in the fridge or at room temperature. You may notice some separation or texture changes after freezing, but this shouldn’t affect the mayonnaise’s safety or quality. Once thawed, use the mayonnaise within a few weeks and store it in the fridge as you would with freshly opened mayonnaise.
What are the signs of spoiled mayonnaise?
Spoiled mayonnaise can exhibit several signs, including an off smell, slimy texture, or mold growth. If you notice any of these signs, it’s best to discard the mayonnaise immediately to avoid foodborne illness. Other signs of spoilage may include a sour or bitter taste, a thick or lumpy texture, or an unusual color.
When checking mayonnaise for spoilage, trust your senses. If it smells or looks off, it’s better to err on the side of caution and discard it. Remember, mayonnaise is a high-risk food that can cause foodborne illness if contaminated, so it’s crucial to handle and store it properly to maintain its quality and safety.
Can I use mayonnaise past its “Best By” date?
While mayonnaise may still be safe to consume past its “Best By” date, its quality and texture may start to degrade. The “Best By” date is a manufacturer-recommended date for optimal quality, not safety. However, it’s essential to use your judgment when using mayonnaise past this date.
If the mayonnaise looks, smells, and tastes normal, it’s likely still safe to consume. However, if you notice any signs of spoilage or degradation, it’s best to err on the side of caution and discard the mayonnaise. Remember, mayonnaise is a high-risk food, and it’s always better to prioritize food safety over convenience.
How should I store mayonnaise?
Proper storage is crucial to maintaining the quality and safety of mayonnaise. Unopened mayonnaise should be stored in a cool, dry place, away from direct sunlight and heat sources. Opened mayonnaise should be stored in an airtight container in the fridge at a consistent temperature below 40°F (4°C).
When storing mayonnaise, make sure to keep it away from strong-smelling foods, as mayonnaise can absorb odors easily. Always check the mayonnaise regularly for signs of spoilage and discard it if you notice any unusual changes in smell, texture, or appearance.
Is homemade mayonnaise safe to eat?
Homemade mayonnaise can be safe to eat if prepared and stored properly. However, homemade mayonnaise is more prone to spoilage and foodborne illness due to the risk of contamination and improper handling.
To make safe homemade mayonnaise, use fresh, high-quality ingredients, and follow proper food safety guidelines. Always handle eggs safely, and make sure to refrigerate the mayonnaise promptly after preparation. Consume homemade mayonnaise within a few days, and discard it if you notice any signs of spoilage or degradation.
