Is it safe to use aluminum foil facing for storing perishable foods like milk or yogurt?

Using aluminum foil facing for storing perishable foods like milk or yogurt is generally safe. Aluminum foil doesn't react with these foods and can help maintain freshness by providing a barrier against light and air. However, it's important to ensure that the foil is food-grade and that the container is properly sealed to prevent contamination. Always check the foil for any tears or punctures that could compromise the integrity of the seal. Additionally, avoid using aluminum foil in direct contact with acidic foods as it may cause a reaction over time.
