is it safe to store food in aluminum foil?

post #1 of 5
Thread Starter 
i've read around that when aluminum foil is heated or comes into contact with highly acidic foods, that it can leach into the food, but i was wondering if anyone knows anything about leaching into non-acidic foods that are stored in the fridge/freezer. Does it leach? is it safe to wrap foods like butter in?

Sorry, I don't know the answer, but I was actually just wondering about this too!

If nothing else, it can ruin the flavor and texture of foods. Foods stored in aluminum long-term take on a "metallic" taste.

PErhaps this also means the food contains dangerous levels of aluminum. Or maybe it just means that you're expensive, carefully prepared whole foods now taste awful and are wasted. In any case, it's not a good choice.

Wax paper or parchment paper is a much safer option- you can wrap foods in paper and then a layer of plastic wrap or aluminum foil. Or, you can just use the plastic. It probably does leach a little bit, but it won't ruin the flavor of foods. Glass or ceramic are by far the safest choices for food storage.

PErsonally, I use glass as much as possible, but I do keep plastic baggies on hand in case I'm out of clean jars, or don't have one the right size (and the bigger one won't fit in my stuffed fridge.)

I would definitely NOT wrap food in aluminum foil, especially something like butter. Use glass or wax paper instead--even plastic is better than aluminum.

I avoid letting aluminum foil or plastic touch my food whenever possible. Aluminum from the foil and dioxins from the plastic will leach into food whenever they are heated or cooled while touching them.
