For sure! You can get food poisoning from eating mayonnaise that has been left out of the fridge too long, and it spoils quicker with increased temperature.
Mayonnaise is a perishable food, and it should not sit out for hours.Yes, mayonnaise can sit out for hours depending on the temperature of the room where the mayo is sitting. For example, in cold areas, mayonnaise is safe for several hours on the counter but in extreme heat, it goes bad quickly.
You can, but it would probably taste bad. (Hot mayo?)As long as it's mayonnaise out of a jar, not home-made, you can put a sandwich with mayonnaise in it on a sandwich grill, or in a frying pan, and it's great.Using a microwave, mayonnaise should be mixed, because otherwise its high fat content will cause it to heat before the other ingredients.
It shouldn't. But if you are concerned, pack your lunch in a small cooler with an ice pack.
Yes
No it cannot go bad in the heat, im no scientist but ive found it just dries it out after long periods of time.
When it turns yellow and smells odd.
No. That is quite true when speaking of commercially made mayonnaise and comparing it to fresh onions.
Mayonnaise is basically made from eggs, dairy foods and vinegar. These are not high in purines which can be the cause of excessive uric acid in the blood.
does tye dressing go bad above 100 degrees unopened
I always put turkey in it and Swiss then heat it. After that you put lettuce in it then put mayonnaise in it. What a treat! You should try it! It is much better if you go to subway and get it there.
Home canning of mayonnaise is not possible. Mayonnaise is an emulsion of oil, lemon juice, and egg yolks. You would have to heat it at some point to can it. If you heat it, you break it, and it will separate. Once broken, it cannot be re-emulsified. Additionally, you would have to use a pasteurized egg product to prevent pathogen contamination from using raw egg. Anyone who makes mayonnaise at home would shudder at the thought of doing such.
Sauce or dressing.
