- Steel: Steel cans are known for their strength and durability, offering a more robust alternative to aluminum. However, like aluminum cans, they may also contain a BPA lining.
In either case, it’s crucial to opt for cans that use BPA-free coatings or materials.
To avoid potential health risks associated with BPA, look for canned tuna packaged in BPA-free plastic or cans utilizing alternative linings. Some packaging options include:
- BPA-free cans: Many companies now offer canned tuna with a BPA-free lining in their containers. These cans are labeled “BPA-free” on the packaging, so you can confidently select a healthier option.
- Glass jars: Tuna packaged in glass jars provides an alternative to traditional cans. Glass is a chemically inert material, which means it doesn’t react with the tuna or leach any chemicals into the food.
- Pouches: Tuna in vacuum-sealed pouches offers another BPA-free alternative, with the added benefit of increased convenience. These pouches are generally made of food-grade plastic, take up less space, and don’t require a can opener. However, be sure to follow the manufacturer’s storage suggestions for optimal freshness.
When you store your canned tuna, choose a cool, dry place away from direct sunlight. This will help maintain the quality and safety of your canned goods. Remember, properly understanding and selecting food packaging materials is a crucial step in ensuring the freshness, flavor, and safety of your canned tuna.
