Does mayo spoil in the fridge once it has been opened?

Question

My husband and i are debating... if a jar of mayo is opened and then put back in the fridge.. does it spoil? and how long until it spoils and becomes no good to eat? thanks

Answer 1

I am not sure of the life span of mayo, but yes it will spoil. It does take longer in the refer then sitting out on your counter.
If a sandwich is made with mayo and sits to long it will spoil and give one a nasty tummy ache.
So whomever said yes then you win :0)
Have a wonderful day!

Answer 2

Yes, but it takes a very long time unless you do what my father daes and lick the spoon and then put the spoon back into the jar for a second helping. There is not much nutrient in mayo for the bacteria to live in. Fat was once used as a perservative. Altering the condition in the jar like adding moisture will help bacteria to grow. Some fats last longer than other, but unfortunatley the ones that are really bad for you last longer than the one that are good for you. This means the lifespan of mayo will alter depending on the type of oil it is made of. Lookin at the experation date will help, but the expiration date is a suggestion more than something written in stone. Its a meean for food company to protect themselves. You could tell by the taste, smell and appearance. I have used mayo long after they expired, but its not an endorsement or a suggestion. Key to prolonging the lifespan of mayo is to put it in the back of the fridge, not in the door. Keep soy sauce and the less perishable on the door.

Answer 3

Everything spoils eventually. If a jar of mayo is opened and left it the fridge (which is where it is supposed to go), I think you can get a good year out of it...but please use your judgement and don't use mayo that smells funny. A good estimate for me would be about 6 months. A year might be pushing it.

Answer 4

I have never known Mayo to spoil however it is usually used up within a month. I think that it shouldn't be kept much longer after the expiration date no matter what. It is so cheap and not worth taking the chance of eating it and getting so sick you want to die.

Answer 5

definite, even though if it takes an exceedingly long term till you do what my father daes and lick the spoon and then placed the spoon back into the jar for a 2nd helping. there isn't plenty nutrient in mayo for the micro organism to stay in. fat replaced into as quickly as used as a perservative. changing the situation interior the jar like including moisture will help micro organism to enhance. some fat final longer than different, yet unfortunatley those that are fairly undesirable for you final longer than the single that are stable for you. this suggests the lifespan of mayo will alter counting on the form of oil it fairly is made out of. Lookin on the experation date will help, however the expiration date is a guideline extra effective than something written in stone. Its a meean for food corporation to guard themselves. you're able to desire to tell via the flavor, scent and visual attraction. I even have used mayo long as quickly as they expired, yet its not an endorsement or a guideline. Key to prolonging the lifespan of mayo is to place it interior the back of the refrigerator, not interior the door. keep soy sauce and the fewer perishable on the door.

Answer 6

Sure, it spoils eventually, whether or not it's refrigerated or opened. There should be a date code on it. In general, only keep it 2-3 months in any event.

Answer 7

AFTER ,ALONG PERIOD OF TIME IT CAN SPOIL. BUT, I'M SURE BY THAT TIME THE MAYO, WILL BE GONE. BY THE WAY, THERE IS AN EXPERATION DATE ON THE LID OR JAR...........!!!!!!!!!!! USUALLY A YEAR...........!!!!!!!!

Answer 8

The whole idea is to refrigerate after opening.Check the label for expiration date.

Answer 9

Yes it will spoil. There should be a date on the label or cap somewhere.
