Standing in the canned goods aisle, you might think all tuna cans are created equal. But those small labels pack crucial information that can make a significant difference in quality, sustainability, and value. Whether you’re a regular tuna consumer or occasional buyer, understanding these key label elements will help you make informed choices.
Species and color designation matter most
One of the most important details on a tuna can is the color designation. The FDA requires manufacturers to specify whether the tuna is “white,” “light,” or “dark.” White tuna exclusively comes from albacore, while light tuna typically comes from skipjack, yellowfin, or tongol species.
What if you found a can without any color designation? That’s a red flag – it’s actually required by law. The species designation also affects price points. White albacore commands premium prices due to its mild flavor and firm texture.
Check the form and packing medium
The form of tuna – solid, chunk, or flaked – indicates how the fish was processed. Solid tuna consists of larger, intact pieces, while chunk style contains smaller, broken pieces. Flaked or grated tuna is more finely shredded.
Pay attention to the packing medium listed. Water-packed tuna retains more natural protein, while oil-packed varieties offer richer texture. Some premium brands use olive oil instead of vegetable oil, which can significantly impact the flavor profile.
Sustainable fishing method certifications
The fishing method used impacts both quality and environmental responsibility. Look for pole-and-line caught or troll-caught designations, which indicate more selective fishing practices. These methods typically result in less bycatch compared to large-scale net fishing.
The Marine Stewardship Council (MSC) blue fish label represents a gold standard in sustainable fishing certification. Additionally, “FAD-free” on the label indicates the tuna was caught without using fish aggregating devices, which can harm other marine species.
Net weight versus drained weight numbers
Many consumers overlook the difference between net weight and drained weight. The drained weight tells you how much actual tuna you’re getting, while net weight includes the packing liquid. This distinction becomes important when comparing prices between brands.
Standard 5-ounce cans should contain at least 2.5 ounces of pressed cake tuna when drained. If you’re comparing prices, calculate the cost per ounce of drained weight rather than the total can weight for accurate value comparison.
Additional ingredients and preservatives list
The ingredients list reveals more than just tuna and water or oil. Some brands add vegetable broth, salt, or preservatives. FDA regulations permit certain additives like pyrophosphate to retain moisture, but they must be declared on the label.
When examining the can itself, check for a BPA-free designation. Many manufacturers have moved away from BPA in can linings, but it’s worth verifying if this matters to you.
Understanding tuna labels empowers you to make choices aligned with your preferences and values. From sustainability certifications to processing methods, each detail on the label serves a specific purpose in informing consumers about their purchase. Remember to check the expiration date and inspect the can for any damage before adding it to your cart.
