does mayonnaise go bad

One of the most popular condiments and additions out there in the food market, Mayonnaise is a common staple for any dinner table, family party, or company event. It is commonly made with egg yolk, oil, lemon juice or vinegar and added with some herbs and spices. It is used frequently in many countries around the world and can be used with many different kinds of food products. Most known for its uses with items like hamburgers, sandwiches, French fries, etc., mayonnaise remains one of the most cherished condiments. When consumers go to their local supermarket and they find a bulk sale on jars or containers of mayonnaise, and they want to save some money by purchasing a few at one time, should they go through with it? How can mayonnaise best be stored correctly for the long-term and would it be possible to do so? The ultimate question remains; does mayonnaise go bad?

Does Mayonnaise Go Bad or Expire?

Mayonnaise, like many other food products does have a tendency to go bad on you especially if its’ not properly stored. Moreover, it does expire, you should always check the “best buy” date of your mayonnaise. It’s important to be able to recognize the telltale signs which indicate whether or not the mayo has gone bad or not. It’s also necessary to check the product consistently before usage so that you avoid making yourself sick or worse from eating mayonnaise. To avoid the mayonnaise going bad, it’s important to recognize how to extend its lifespan as much as possible through some simple steps and procedures.

How Long Does Mayonnaise Last

Because of its preservatives and pasteurized eggs, the mayonnaise that you buy in bulk at the local supermarket can last up to two months after initial purchase with proper storage in the refrigerator. If you decide to make your own mayonnaise at home, it will only last about one to two weeks with proper storage in the refrigerator. Homemade mayonnaise may be of a higher quality than store-bought mayonnaise though because of the fresh ingredients like raw eggs and low-fat milk. Even though mayonnaise is known to go bad after a few weeks or a few months depending on how its’ made, you will get more bang for your buck if you properly store and refrigerate the product. Buying the mayonnaise in bulk will be a good decision due to the condiment’s variety of uses and its’ popularity with many consumers even including your friends, family, and neighbors.

Storing the Mayonnaise

When you buy a new, unopened can or jar of mayonnaise, it’s very important to store the product in a cold, dark area away from sunlight or a lot of heat. It’s also permissible to store mayonnaise at room temperature as long as its’ not too sunny or humid in the room. In this case, it’s important for consumers to be aware of the expiration date on the jars or cans of mayonnaise. If you haven’t used or opened up the mayonnaise by the “Best by / Use by” date, your mayonnaise should still be okay to use at least a week beyond a “best by” date, being on the safe side. If longer time has passed then it’s probably a good idea to throw the product out because it will have gone bad by then. It may look fine, but make you very sick. Consumers should always check what the date of expiration is for their mayonnaise before they go ahead and use the condiment.

Whenever you open the mayonnaise container for the first time, it’s important to seal it tightly afterwards to prevent oxygen and other outside elements from affecting the taste and texture of the food product. Opened cans or jars of mayonnaise must also be placed in the refrigerator as well after first usage for the best means of storage. As for the timeline of mayonnaise after its’ been opened and refrigerated, it can usually last up to two months total before it begins to spoil and go bad. Mayonnaise that has been used in a sandwich, salad, or another food product should be consumed within an hour unless it is then refrigerated which would extend its lifespan for up to an entire week.

Signs of Bad Mayonnaise

Before we can learn about how to properly store mayonnaise so that it doesn’t go bad pre-maturely, it’s important to be able to recognize the signs and clues that will tell you whether or not the mayo is still good or has gone bad. When you smell the mayonnaise and take it in, you should recognize whether or not it has a bad odor or not. If it has an off or bad odor, chances are good that the product has gone bad already. If the smell is really awful or makes you nauseous, you can rest assured in knowing that your mayonnaise has soured on you.

Also, if the mayonnaise has changed color and no longer looks white but instead has a yellow or brownish appearance then the product should be sent for the trashcan. If the texture has also become clumpy or shows signs of mold in its contents, then you will want to throw the product out. If you’re still not sure about whether or not your mayonnaise has gone bad or not, it’s important to do a small taste check to see for yourself if its’ worth eating. Please remember that a small taste of mayonnaise even if its’ gone bad won’t necessarily make you sick.

Conclusion

Coming back to the previous question, yes your mayonnaise can go bad and expire. However with the correct storage methods you can preserve its shelf life. Just make sure to watch out for any unusual changes of your mayo’s smell, color or taste.

Enjoy this thick and creamy dressing with your salads, vegetables, hamburgers, sandwiches, french fries, cold fish entrees, or other foods!
