6538 Posted December 9, 2009 Share Posted December 9, 2009 Right, so I'm here stuffing Branston beans in my face straight from the tin (bought in bulk while on sale for fvck all at Morrisons, of course) and remembered something my mother and grandmother told me years back. Apparently, you shouldn't put opened tins of food in the fridge as it causes something nasty to happen - problem is I don't know what or why. Surely this is some sort of old wives tale or is there any truth to it? Link to comment Share on other sites More sharing options...

Open tin - oxygen reacts with tin which leaches into the food - especially acidic foods - tomatoes, grapefruit, etc. A high intake of tin can cause a stomach upset and dihorrea.

About 10 years ago the EU lowered the permissible level of tin in food. Heinz / Campbells in response to this had to lacquer the insides of their tins with plastic - particularly as tomato soup is very acidic. When they did this they got loads of compalints because the soups had lost their characteristic zingyness! Link to comment Share on other sites More sharing options...
FedupTeddiBear Posted December 10, 2009 Share Posted December 10, 2009 I've heard something about open tins and botulism. As tinned food is made without preservatives, bacteria multiply quite quickly once the tin is opened. Botulinium is found in low-acid foods. I think the danger of this is more from eating the contents of a dented or punctured tin than from leaving the food in the tin, though. I have also heard that storing food that is part-eaten (licked utensil has been in it) is a bad idea as the bacteria multiply. Link to comment Share on other sites More sharing options...

The only way botulism will grow is if the tin is inadequately processed (too low temperature). Botulism will only grow in an air free environment - once there is air - botulism spores stay dormant. As for dented tins - if the seal is broken they invariably spoil. Link to comment Share on other sites More sharing options...
Sledgehead Posted December 10, 2009 Share Posted December 10, 2009 I would not be too concerned myself, but food standards agency don't recommend. It is true that cans do corrode pretty quickly when exposed to the atmosphere, but tin isn't exactly the world's greatest health threat. If you believed that you'd have to start asking why they still use the stuff to coast steel when so many polymers are available. The botulism issue is no more of a problem whether you leave the beans in th etin or take them out. Moreover factory canning temperatures exceed those needed to kill botulism, and if they did not, it would multiply inside the can to lethal levels before you even opened it.

Kurt Barlow Posted December 10, 2009 Share Posted December 10, 2009 Take a tin of pineapple, eat half of it and put the rest in the fridge for 2-3 days. See if you want to eat the rest of it. The tin does oxidise and turn black which is nasty. Pineapple juice is incredibly corrosive. You can literally cook raw pork in it. Link to comment Share on other sites More sharing options...

Myth busters tried all this. Great fun. The best effect was from two strips of aluminium foil, folded into a zig zag, and placed on their edges, parallel in the microwave. Beautiful light show. I forget if you had to have the points close together or separate, it wasn't dangerous either way but one gave the best display. Link to comment Share on other sites More sharing options...

I've not seen many with polymer liners but sweetcorn seems to be one that usually is. The one I ate last night was definitely metal lined. Link to comment Share on other sites More sharing options...

Kurt Barlow Posted December 10, 2009 Share Posted December 10, 2009 I was told never to reheat rice either, but I've been doing that for 2 decades. The problem with rice is that the spore forming pathogen bacillus Cereus is often present in rice. No problem if you cook, chill rapidly and then reheat. Problem occurs when its - cook, sits around for several hours and then refrigerated or eaten. During that period spores activate, multiply rapidly and produce a heat stable toxin which isn't destroyed when the food is reheated. Consume that toxin and you will have 12-24 hours of violent sickness and the shits. Link to comment Share on other sites More sharing options...
RichB Posted December 10, 2009 Share Posted December 10, 2009 certainly in the old days tin cans that were dented created an interesting effect - the dent would often crack the tin lining. This then exposes both the tin and the underlying steel to whatever is inside - so if that is at all liquid/acid it begins to electrolyse the contents with all sorts of bad things happening to the food...

So it's sat around all day till your 11.00pm apres pub, beer munchies. Why are we not all poisoned? Link to comment Share on other sites More sharing options...
