    Are Metal Containers Safe for Food Storage?

    Stainless Steel

    • Highly resistant to corrosion and rust.
    • Does not leach harmful chemicals into food.
    • Ideal for storing both hot and cold foods.

    Aluminum

    • Lightweight and affordable.
    • Can react with acidic or salty foods, potentially altering taste and safety.
    • Anodized aluminum containers reduce reactivity.
