For a larger meal, work out how much drained tuna the recipe needs before choosing between a multipack and a larger single tin. Spring-water chunks give you a starting point without brine when mixing tuna with other ingredients; brine-packed chunks may fit a seasoned dish, but check the exact product’s salt information alongside the rest of the meal. A smaller no-drain pack is worth considering when avoiding preparation steps matters more than the amount needed at once.
If tuna is going into a dish for several people or meals, the usable amount after draining matters more than the number of tins. Tesco’s stated drained weight and Princes’ range of pack formats give you two ways to plan the quantity.
If the tuna will be mixed with potatoes, vegetables or a sauce, check the packing liquid, ingredients and salt information against the other parts of the meal.
If a certification or fishing-method statement affects your choice, look for it on the exact product. Tesco, M&S and Princes describe different sourcing information, which should not be assumed to apply to every tin in their ranges.
Decide how much tuna the recipe will use, then compare packing liquids and any product-specific sourcing information.
| Concern | What to check | Who this matters to |
|---|---|---|
| Usable quantity | Compare total drained weight with the amount your recipe requires. Tesco lists 4 × 102g drained for its 4 × 145g brine pack; Princes lists spring-water formats up to 8 × 145g but pack weight is not the same as drained weight. | I am making enough for several people or planning another meal, so I need to know how much tuna will be left after draining. About 42% of consumers put usable quantity first. |
| Packing liquid and salt | Read the exact ingredients and salt figure, using the same per-100g basis when comparing products. Consider the gravy, stuffing or sauces in the complete meal. | If I am mixing tuna into an already seasoned dish, I want the packing liquid and salt contribution to fit the recipe. Recipe fit is the primary concern for about 33% of consumers. |
| Product sourcing | Check the exact tin for the certification, fishing-method or traceability wording you want; do not extend one product’s statement across a brand. | When stocking the cupboard, I want sourcing information I can identify on the product I will use. About 25% of consumers place that product-specific information first. |
Packing liquid contributes to the weight on the front of a tin. Tesco’s 4 × 145g brine pack, for example, provides 4 × 102g drained.
Calculate the amount your dish needs using drained weight, then choose the tin size and pack count.
Brine contains salt, and roast-dinner ingredients such as gravy, stuffing and stock may also be seasoned. A tin’s packing liquid alone does not tell you how the finished dish will taste.
Compare product labels on the same per-100g basis and decide how to season the dish as a whole.
Storage instructions and stated periods after opening can differ. Food Standards Scotland advises checking the product label for both.
Before opening a tin, plan when you will use any remainder and follow that product’s transfer, refrigeration and use-by instructions.
Opening more tuna than the meal needs can leave food to use within a short stated period.
A certification on a Tesco product, M&S’s statement about a particular spring-water tuna and Princes’ brand-level traceability statements have different scopes.
Check the wording on the exact tin or its product page before using a sourcing claim to choose a format.
Tesco’s own-label brine multipack offers a stated drained-weight figure for planning a larger dish.
Princes lists tuna chunks in several packing liquids and spring-water tins in single and multipack formats.
A no-drain option may appeal when a smaller, quicker-to-prepare pack fits the meal.
M&S lists spring-water chunks alongside larger tinned-fish formats, including 640g tuna chunks.
These tuna-chunk multipacks offer spring-water and brine options for planning a larger meal or using tins across several meals. Check each pack’s drained weight against the amount you intend to prepare.

A six-tin spring-water pack to consider when tuna is planned across meals. Check its drained weight for portion planning and its ingredients and salt information against the recipe.

A four-tin spring-water format for a dish or several planned uses. Use the pack’s drained weight, rather than its stated tin weight, to work out how much the recipe will have.

This larger bundle suits planned use over multiple meals if brine fits the dishes you have in mind. Check the drained weight of the tins and the label’s salt and storage information before planning portions.

A six-tin brine pack for meals where that packing liquid suits the recipe. Check drained weight and salt on the exact label; the product information also notes that some bones may remain.

A four-tin brine option for a planned dish or use across meals. Confirm the pack’s drained weight for portions and check how its salt fits the meal; the product information notes that small fish bones may remain.
Start with the total drained weight needed for the recipe, not just the number or stated weight of the tins. Tesco Groceries lists 4 × 102g drained for its 4 × 145g brine pack; for any other format, check its own drained-weight label before calculating portions.
Choose according to what you will mix with the tuna. Princes lists tuna and spring water as the ingredients of its cited spring-water chunks, while Tesco lists tuna, water and salt for its cited brine product. Check the exact pack’s salt information alongside other seasoned ingredients in the meal.
Follow the storage and use-after-opening instructions on that tin. Food Standards Scotland advises checking food labels for the correct storage method and any stated period for eating the contents after opening.
Yes. The NHS advises people who are pregnant or trying for a baby to have no more than four cans of tuna a week, or two tuna steaks a week, because tuna contains higher levels of mercury than other fish. That guidance concerns consumption, not the size of a pack bought for a household.
Yes. The Food Standards Agency identifies fish as an allergen, and tuna is fish. Check the ingredient and allergen information on the exact pack when preparing food for someone with a fish allergy.
