I think it's something to do with either acidic stuff in the food reacting with the metal or the tin leeching metal ions into the food. Which isn't too good for you. Allegedly. Dunno if that actually happens or not, but if a restaurant was found leaving opened tins in the fridge by an inspector they'd be in trouble; I am informed of this fact by a professional chef.

I think that this may be harking back many years when cans involved dipped tin plate and tin based solders to seal them Tin as an element exists in several allotropic forms one of which (grey tin) is stable at low temperatures (-10 deg c or below) This is very weak structurally and tends to turn into powder. Tins have failed in the past at low temperatures. nowadays tins are mostly protected by a lacquer that stops them rusting and seals the tightly crimped joints so I don't think that the caution would apply. also an open tin will oxidise faster and ends up contaminating food. might not be the case but its better not to do it still just in case

If you do that, you're at risk of getting Cholstridium Botulinum which is a form of food poisoning. You also shouldn't purchase dented cans or if you do dent a can, you should throw it a way, as the metal in the can reacts with the food.

Some people overworry over food it's actually quite pathetic. I'm talking in general though.

When you have opened a can of food and you’re not using all the food straight away, empty the food into a bowl, or other container, and put it in the fridge.

Don’t store food in an opened tin can, or re-use empty cans to cook or store food. This is because when a can has been opened and the food is open to the air, the tin may transfer more quickly to the can’s contents.

This advice doesn’t apply to foods sold in cans with resealable lids, such as golden syrup and cocoa.
So there you go

I leave sweetcorn in the tin and put clingfilm over the top then it doesn't smell in the fridge.

Segat explain to your housemate that CLINGFILM is the key. My housemate doesn't belive in cling film cos it 'makes food sweat' which drives me up the wall. FIRSTLY: Nothing can sweat at like 2c and SECONDLY: I don't care if your food sweats as long as all my food doesn't smell and taste like white onion.

Chemistry - it's so much fun isn't it So shockingly handy though, in everything, almost.

Oh yeah! Chemistry's ruined my mind though. Sometime ago I fell asleep on the sofa and had a dream about mass spectrometry, and then my mum woke me up and asked what I wanted for dinner. I was still half asleep, but apparently I got a piece of paper and started trying to work out the correct RFM of the dinner I wanted!

It annoys me when my flat mate puts unopened tins of tuna in the fridge, because it takes up room...but then again this is the girl who asked me if it was ok to keep lemons in the dark :rolleyes:
