What creates the vinegar-like flavour in non-alcohol foods that've been sitting out? And is it safe to eat?

Question

I understand that vinegar is fermented wine (which is itself fermented sugar). But when I leave something like a cup of soup sit out for awhile, it begins foaming and develops a vinegar taste. This isn't food with alcohol in it (it even happens when I'm soaking a pot of beans, there's nothing but beans and water and the foaming/vinegar still happens), so:
1) What microbe (if that?) is causing the foaming,
2) Is it vinegar or something chemically related?
3) Is it safe to eat "raw"? I return any affected foods to a boil to kill off anything unsafe, and I don't mind the vinegar flavour, I just wonder if I need to be re-cooking the stuff.

Even if you can't answer #1, I'd apreciate the answer to #2. I'm mainly confused about what it is, because it tastes like vinegar but I'm told that vinegar only comes from alcohol.

Whatever that microbe is, I must have a LOT of it in my apartment's air, because I get that foaming action quickly. =p

Answer 1

any food with sugars will ferment and cause alcohol/vinegar tastes to arise. do not reheat. throw these items away. they are spoiled. as for the beans, that is common when soaking. that is a chemical reaction and they are just giving off gas. much as you will when your body finishes processing the beans the next day. lol

Answer 2

I wouldn't eat the soup that sits out. That needs to be tossed because the foaming is the beginning of the end. It's starting to go bad and you shouldn't risk sickness and eat it. Toss it.

As far as beans soaking in water and foaming, that's gas and it's ok.

1) ?
2) it's a chemical reaction that happens with the air and cooling process. it's basically the decomposition process of food.
3) I wouldn't reheat/boil and eat. Just get in the habit of covering and refrigerating leftovers.

Answer 3

It basically something that through our Prophets- like Thomas S. Monson- God has requested us now to not do, alongside with drink espresso, tea, chew, drink alcohol, etc. those are to guard us. Our faith is depending a lot off of religion. that's because we do not continuously recognize the solutions, yet we were advised that they are going to guard us. possibly not each and every man or woman receives a disease from ingesting too a lot and tea would help someone someplace, yet for most individuals it would not. as an party; Joseph Smith requested the adult men now to not chew previously all and sundry knew that it became undesirable for you. also, our prophets requested us to commence saving and to prepare our seventy 2 hour kits (like a survival kit) waaaaaay previously the recession. because of this the individuals who did commence early at the instantaneous are financially set or are waiting for regardless of will hit next. We had faith to maintain on with our prophet and thanks to it we are now blessed. Tea each and every now and then does help with diseases yet we are able to stay with out them! we do not choose them to stay so why placed ourselves through that when we do not might want to? possibly not each and every thing in our faith is sensible now yet we believe that's going to sometime. If we are incorrect, then what did it damage? our bodies are sparkling and healthful. sure some would have drank tea and they are fantastic, yet we are only as healthful with out it. There are different kinds of drugs to help us. those who opt for to drink it basically made a call. all of us do. (I used the party of tea a lot regardless of the indisputable fact that an same is going for countless the food and drink that we are hostile to)
