What Makes Canned Tuna A Processed Food?

What makes canned tuna a processed food?

Canned tuna, a staple in many pantries, is often overlooked as a processed food despite being a convenient and affordable source of protein. The term “processed” refers to foods that have undergone significant alteration from their natural state, and canned tuna certainly fits the bill. From harvesting and catching wild tuna to canning, packaging, and distribution, this fish undergoes multiple processes that transform its original form. Here are some of the main ways canned tuna becomes a processed food: the tuna is first caught or farmed, then gutted, beheaded, and cleaned, followed by a thorough washing and removal of any remaining bones or blood. Next, the tuna is soaked in a brine solution or coated with a acidic agent to prevent spoilage, before being heated to kill any bacteria or parasites. The tuna is then packed into cans, often with added salt, preservatives, or flavorings, and sealed to preserve freshness. Finally, the cans are sterilized through heat or irradiation to extend their shelf life. While canned tuna can be a healthy addition to a balanced diet when consumed in moderation, it’s essential to recognize its processed nature and consider the potential impacts on nutritional value and environmental sustainability.
