Salt-conscious second-home cooks
If you keep tomatoes for sauces, soups or stews, compare salt per 100g on the exact tin rather than relying on its brand, origin or front-of-pack wording.
Who is this for?
The amount you cook during a stay matters alongside the salt declaration on the tin.
Occasional cooks making small meals
A 227g tin is worth considering when a short stay might end before you can use the remainder of a 400g tin.
Households cooking several meals
400g tins or multipacks may fit repeated cooking. Check how much cupboard stock you will use and follow each product's instructions once a tin is opened.
What should you check?
Start with a comparable salt figure, then match the tin size and storage instructions to the meals you expect to cook.
| Priority | What to check | Your needs |
|---|---|---|
| Salt declaration | Compare salt per 100g on the current label. The NHS defines low salt as 0.3g or less per 100g; also check the amount per serving or tin for the portion you plan to use. | I want a comparable figure across different tin sizes, rather than assuming that a product description tells me how much salt it contains. |
| Tin size | Check whether 227g or 400g matches the recipe. Sainsbury's describes its 400g chopped-tomato tin as serving two and says opened contents should be refrigerated and used within 2 days. | For a brief solo visit, I would rather open a tin I can finish. If I am cooking for two or making several dishes, I can plan how to use a larger tin. |
| Seasoning | Read the ingredients as well as the nutrition panel. Check plain and flavoured variants separately: Napolina offers chopped tomatoes with garlic, herbs or chilli alongside its plain product. | I want a tomato base I can season differently for each meal, without assuming that a flavoured variant has the same salt declaration as the plain tin. |
| Storage | Check the best-before date, unopened storage directions and the instructions for opened contents. Sainsbury's specifies a cool, dry place for its 400g tin and use within 2 days after opening; its listed Cirio multipack gives 3 to 4 days after opening. | Before leaving stock at the second home, I need a suitable cupboard. If I open a tin near the end of a stay, I need to know whether I can use the remainder in time. |
What can go wrong?
-
Assuming Italian origin or an Eat Well marker means lower salt
Neither description states a comparable salt figure. For example, the Sainsbury's listing for Cirio Chopped Tomatoes 4 x 400g reports less than 0.5g salt per 100g; that figure does not establish whether it meets the NHS low-salt threshold of 0.3g or less per 100g.
Use the current per-100g salt declaration to make the comparison, then check how much tomato your recipe uses.
-
Opening a 400g tin on the last day of a short stay
If a meal uses only part of the tin, the rest needs to be handled within that product's instructions. Sainsbury's says to transfer its 400g chopped tomatoes to a non-metallic container, refrigerate them and use them within 2 days.
Consider a 227g tin for a smaller meal, or plan another dish that uses the remainder.
-
Relying on an old label when replenishing the cupboard
A previous salt figure should not stand in for the declaration on the pack you are buying now.
Recheck the ingredients, salt per 100g and storage directions on the current tin, particularly when switching sizes or variants.
-
Seasoning without tasting the finished sauce
Salt added during cooking changes the finished dish, regardless of the figure on the tomato tin.
Taste before adding salt. The NHS suggests herbs, spices, garlic, chilli or lemon juice as ways to add flavour while cutting down on salt.
Brand and product references
These examples concern the specified products and pack sizes, not every tin sold under each brand.
Tesco
Tesco Italian Chopped Tomatoes 227g is a small-tin reference for comparing salt declarations.
- Tesco lists less than 0.01g salt per 100g for this product.
- Check the current pack before applying that figure to a repeat purchase or a different Tesco product.
Sainsbury's
Its listed chopped tomatoes include both 227g and 400g tins.
- Sainsbury's lists 0.07g salt per 100g for each of these two products.
- For its 400g tin, Sainsbury's says to refrigerate opened contents and use them within 2 days.
Napolina
Napolina lists plain chopped tomatoes in 227g, 400g and 4 x 400g formats, as well as separate flavoured variants.
- The range offers a choice between a smaller tin and packs for repeated cooking.
- Compare the current salt declaration for the exact plain or flavoured variant you intend to buy.
Mutti
Mutti Polpa is described by Sainsbury's as finely chopped tomatoes for shoppers seeking that texture.
- Sainsbury's describes the listed product as made with Italian tomatoes.
- Texture and origin do not establish its salt level; compare the declaration on the exact pack.
Cirio
Sainsbury's lists Cirio Chopped Tomatoes as a 4 x 400g multipack.
- Its listed ingredients include tomatoes and salt, making the ingredient check relevant when choosing a plain base.
- The listed figure of less than 0.5g salt per 100g is not precise enough to establish whether it meets the NHS threshold of 0.3g or less per 100g.
M&S
M&S describes its 400g Chopped Italian Tomatoes as packed in tomato juice and carrying its Eat Well flower.
- The product description identifies the tin and its tomato-juice packing.
- The Eat Well marker is not a substitute for checking salt per 100g on the current pack.

Frequently asked questions
What counts as low salt on a UK tinned-tomato label?
The NHS defines low salt as 0.3g or less per 100g. Use the per-100g figure to compare tins of different sizes, then check the per-serving or per-tin figure for the amount you will cook.
Should I stock 227g or 400g tins for a second home?
Choose a size that fits the meals you actually make: a 227g tin can limit leftovers from a small meal, while a 400g tin suits a larger recipe or a meal using the whole tin. If you will use only part of a 400g tin, check that you can refrigerate and finish the remainder within its stated period.
How long can opened tinned tomatoes be kept?
Follow the instructions on the specific product. Sainsbury's says to transfer its 400g chopped tomatoes to a non-metallic container, refrigerate them and use them within 2 days; its Cirio multipack listing specifies refrigeration and use within 3 to 4 days.
Is an ingredient list without added salt enough to choose a lower-salt tin?
No. Check the nutrition panel as well: salt per 100g is the comparable figure for the tin you are buying. The listed Tesco 227g and Sainsbury's 400g plain chopped tomatoes provide examples of products with salt declarations below the NHS low-salt threshold, but their figures should not be applied to other variants.
Does an Eat Well marker or Italian origin mean lower salt?
Neither description establishes the salt content. M&S describes an Eat Well marker on its Chopped Italian Tomatoes, and several brands highlight Italian tomatoes; compare the current salt figure per 100g if salt is the deciding factor.
