Supermarket Canned Tuna: Taste Scores and Sustainability Ratings
9/6/2026, 8:00:03 AM
What the Tasting Revealed
A recent tasting of a range of UK supermarket tinned tuna evaluated texture, aroma, and flavour when eaten straight from the tin. The reviewer found most products “gruelling” to eat unseasoned, noting that skipjack generally offers a softer, flakier texture while albacore provides larger, meatier flakes with a milder taste. The overall sensory scores ranged from four stars for the top-rated albacore steak to one star for the lowest-rated skipjack chunks.
Sustainability Guidance from the Marine Conservation Society
The Marine Conservation Society (MCS), an independent environmental charity, uses its Good Fish Guide to rate seafood sustainability on a green-to-red traffic-light scale. Both skipjack and albacore have green-rated options, but the guide emphasizes that the catch method, region, and certification matter. MCS recommends pole-and-line fishing as the most sustainable, followed by Marine Stewardship Council (MSC)-certified hook-and-line (which can include less sustainable longline practices). FAD-free purse seine methods are also highlighted for their lower by-catch compared with standard purse seine.

Consumer Takeaways
For shoppers prioritising both flavour and environmental impact, the highest-scoring options are Sainsbury’s albacore steak and the Co-op’s skipjack chunks, both caught by pole-and-line and bearing MSC certification. Products labelled “FAD-free purse seine” also represent a relatively sustainable choice, though they tend to score lower on taste. When sustainability information is absent, as with Asda’s offering, the reviewer advises caution. Overall, the tasting underscores that sustainable catch methods often align with better texture and flavour, reinforcing the value of looking for “pole and line” or “FAD-free” labels alongside MSC certification.
