My Leftover Lasagna Burned Holes in Aluminum !

- I found some 2 Day old leftover lasagna in my refrigerator and I noticed holes in the container, upon further inspection I realized that some sort of chemical reaction has taken place and the meat in the lasagna apparently burned holes in the aluminum pan it was stored in... wow!
I'm told that this was homemade lasagna but now I'm having my doubts, I think it was store bought or came from a nuclear power plant because it seems the the part of the aluminum lid that was touching the meat has corroded to the point where there are holes.
the only way I know of that this could happen is if there's some serious preservatives in that lasagna, so I'm not too sure that I believe it's homemade. - Наука та технологія
Its from the acidity in tomatoes. Not preservatives. I've seen it before with aluminum foil
Set-up the ultra slow motion camera. We want to see the gremlins doing that!
I’ve had vinegar based homemade Carolina style bbq sauce burn holes in aluminum in a short time. That same sauce burned holes all the way through a giant aluminum cooking pot while it cooled overnight in the fridge. I’m betting that tomato sauce in the lasagna is acidic enough to burn through the aluminum tbh. Wouldn’t surprise me a bit.
Everyone is answering it wrong. This was caused by galvanic corrosion the aluminum is acting as positive and negative electrode and the food acting as electrolytes. Basically the entire thing is in short circuit and it bite through the metal. It's hard to explain. Maybe you can try to google the galvanic series chart to understand more.
Most of the comments say to put plastic wrap on it is basically to prevent the short circuit
Last time I just put rice in it and it also make hole so it's not acidity
Metallurgist here. It's a combination of salt and acid. I also suspect that the pan and lid might be slightly different alloys adding a galvanic component.
The acid in the pasta sauce(tomato acid) !!!
I found it on the portions of the aluminum where it was touching the meat if that's what you want to call it.. lol.
Was going to say the same thing. There's not generally an added base in fresh tomato sauce, whereas canned/prepared sauce would probably have a base/buffer (loads of sodium citrate, or others like it) to try and prevent the very thing you saw. .
Do I smell an experiment for a future episode? Would make a very interesting one for sure.
Not from preservatives
Tomato sauce acid for sure, but the speed is fast, so it must be accelerated by something else. Worst thing is that cooking or storing anything containing tomato sauce in a metal, ruins the taste, making it very sour.
I've never seen this at all...not from preservatives or acidic foods. I also use aluminum foil for everything.
Gotta love acid, even the mildest can eat
Like everyone else is saying, the tomato's acid is causing it. I always put plastic wrap down first before covering with the foil and mine is homemade.
Salt will do that.
It's not (necessarily) from tomato acid as other have pointed out, it's a chemical reaction caused by two dissimilar metals effectively creating a battery.
I have seen it many times with simple things such as a plastic bowl of pasta, with a stainless spoon in it, and aluminum foil over, it will also etch holes in the aluminum where the pasta touch the aluminum, if you leave the spoon out, it doesn't.
I have also tried with tomato sauce, and i have never seen holes unless there were two metals in play.
Edit: It's called Galvanic Corrosion: en.wikipedia.org/wiki/Galvanic_corrosion
That's what I thought to, simply because aluminum corrosion is usually white in color, when you have galvanitic corrosion or the battery situation like you said it's black from what I've seen. If it has potassium nitride as a preservative in the meat I believe that will react with aluminum...
