Shoppers checking sugar on the label
If the tuna itself needs to contribute little sugar to a Bonfire Night dish, compare the per-100g figure on the exact tin. Sauces and other additions need checking separately.
Who this is for
Bonfire Night batch cooks
For a shared jacket-potato topping, pasta bake or sandwich filling, pack count and drained weight help you work out how much tuna is available for the planned portions.
Quick-serve shoppers
A no-drain tin can remove a preparation step when food needs assembling quickly. Check its packing liquid, salt figure and instructions for storing opened contents.
What to check when buying
| Concern | What to check | Who this matters to |
|---|---|---|
| Sugar in the tuna | Compare “of which sugars” per 100g on the same drained or as-sold basis. Check the ingredients of dressed or flavoured products separately. | If I want to keep sugar in the tuna base to a minimum, I need its own label figure rather than a figure for the finished dish. About 36% of consumers put a comparable sugar value first. |
| Quantity for a shared meal | Check the number of tins and their drained weight where shown; follow the tin's instructions for any opened leftovers. | When making a shared Bonfire Night dish, I need enough usable tuna without opening tins I cannot finish. Having the right quantity is the primary concern for about 29% of consumers. |
| Quick serving | Confirm that the exact variant is no-drain, then check its packing liquid and per-100g salt figure. | If I am assembling food close to serving time, skipping the draining step matters more to me than the format of a conventional tin. Quick, low-mess serving comes first for about 21% of consumers. |
| Sourcing information | Look for a certification or fishing-method statement on the precise product, rather than assuming it applies to a whole brand. | I want to see a sourcing statement for the tin I am actually buying before choosing it for the meal. About 14% of consumers make that product-level information their primary concern. |
Buying pitfalls
-
Assuming the tuna figure covers the whole dish
A plain tin can list 0g sugars per 100g while sauces, chutney or other ingredients contribute sugar to a tuna topping or filling.
Choose the tuna using its own label, then check the other ingredients when assessing the finished recipe.
-
Using tin size as the amount of tuna
Tesco Groceries lists 102g drained weight for its 145g spring-water tin. Its Princes four-pack listing gives four 145g tins with 102g drained weight each, so the weight on the front of a tin is not necessarily the amount available after draining.
Use drained weight where stated to plan portions, and check the exact pack if that figure matters to your meal.
-
Assuming the packing liquid determines salt content
The checked Sainsbury's brine product lists 0.42g salt per 100g drained, while the John West no-drain spring-water chunks listed by Tesco Groceries show 0.80g per 100g. These are figures for specific products, not rules for brine or spring water.
Compare the salt panels on the tins you are considering, using the same nutrition basis.
-
Overlooking the exact can's safety information
Tuna contains fish, and some product listings warn that bones may remain. Those details matter when preparing food for other people.
Read the allergen and possible-bones statements on each product before serving it.
Brands to consider for these tuna formats
Tesco
Its 145g Tuna Chunks in Spring Water offer a single-tin format for a plain tuna base.
- Tesco Groceries lists 102g drained weight, 0g sugars and 0.90g salt per 100g drained for this product.
- Use the exact tin's label when comparing its salt figure or planning portions.
Princes
The spring-water four-pack gives cooks separate tins for a shared meal or more than one preparation.
- The Tesco Groceries listing gives four 145g tins, each with 102g drained weight, and 0.0g sugars per 100g drained.
- Its listed salt figure is 0.85g per 100g drained; check the specific variant rather than applying that figure to other Princes tins.
John West
The checked No Drain Tuna Chunks with a Little Spring Water are a 3 x 100g option when preparation time or mess matters.
- Tesco Groceries lists 0g sugars and 0.80g salt per 100g for the checked spring-water chunks.

- Sainsbury's lists less than 0.5g sugars and 0.42g salt per 100g drained for this product.
- The less-than-0.5g declaration is not identical to a displayed 0g value; compare the labels on the same basis.
M&S
Its 160g Tuna Chunks in Spring Water combine a plain format with a product-specific fishing-method statement.
- M&S lists 0.0g sugars and 0.75g salt per 100g for this product.
- M&S describes this tuna as pole-and-line caught under its Forever Fish policy; check the statement on the exact product rather than extending it to every M&S tin.

Questions about choosing and storing tuna
Do I need a tin labelled reduced sugar?
Choose by comparing the sugar figures on the tins you are considering, using the same per-100g basis. Tesco Groceries lists 0g sugars for its checked Tesco, Princes and John West spring-water products, M&S lists 0.0g for its checked spring-water tuna, and Sainsbury's lists less than 0.5g for its checked brine tuna. Sauces and other ingredients need separate consideration for the finished dish.
How should I store tuna left over after opening a tin?
Follow the instructions on the exact tin. The checked Tesco and Princes products say to transfer unused contents to a non-metallic container, refrigerate them and use them within two days; the checked Sainsbury's product gives the same transfer and refrigeration instructions but says to use the contents within one day.
