Question

Aluminum foil is malleable that is it can be convered into thin sheets. Also it protects food from air and moisture. so why it is harmful for covering eatables?​

Answer 1

Answer:

It is extremely malleable and can be shaped into very thin sheets. One of the most common uses of aluminum is to make food-wrapping foil. To turn it into foil, a block of aluminum is squashed through rollers again and again until it is a long flat sheet.

aluminium foil should not be used for cooking. ... It's safe to wrap cold food in foil, though not for long stretches of time because food has a shelf life and because aluminium in the foil will begin to leach into the food depending on ingredients like spices.
