3 Reasons Oil-Packed Tuna Tastes Better
Oil acts as a buffer against metallic flavor The metallic taste in tuna usually comes from the can liner reacting with the fish. Oil prevents direct contact between the fish and the metal, reducing that off flavor.
Water-packed tuna sits directly against the can When tuna is packed in water, it touches the tin or aluminum directly, which can cause a chemical reaction over time. Oil-packed tuna avoids this problem entirely.
Cheaper brands use older stock that amplifies the issue Lower-quality or older fish that has sat on shelves longer tends to taste more metallic. Stick with oil-packed tuna from reputable brands like Wild Planet, Ortiz, or Bumble Bee Solid White in oil for a cleaner taste.
