Aluminium leaching

Aluminium can leach into acidic foods like tomatoes, citrus fruit, pickles and vinegar-based marinades.

Avoid storing salty food items at high temperatures for longer durations. It can leach aluminium particles into food.

Bacterial growth

Long-term exposure to aluminium can impair kidney function, cause bone damage, reduce calcium absorption and cause developmental disorders in children.

Safe usage

Aluminium foil is generally considered safe for wrapping food for a shorter period of time or for cold storage
