Guests cooking several shared meals
Chopped tomatoes can form the base of sauces, soups, stews or chilli during a short stay. Compare salt per 100g alongside the number of tins you expect to use.
Who is this for?
Shoppers comparing declared salt
Read the nutrition panel rather than treating Italian origin, texture or a brand name as a guide to salt content. A value per 100g makes differently sized tins easier to compare.
Hosts stocking a cottage cupboard
Choose a pack quantity that fits likely use, and leave guests the product-specific directions for storing tomatoes left over after opening.
What should you check?
Start with salt per 100g if that drives the purchase, then match the tomato cut, quantity and opened-storage instructions to the stay.
| Priority | What to check | Your needs |
|---|---|---|
| Declared salt | Compare salt per 100g on like-for-like tins. Marks & Spencer lists 0.02g for its standard Chopped Italian Tomatoes; Tesco lists 0.09g for its Italian Chopped Tomatoes multipack. Check the current tin before buying. | I want to compare the tomato base by its declared salt value, without assuming that a lower number is a ‘reduced salt’ claim. |
| Tomato texture | Check whether the tin contains chopped or finely chopped tomatoes. Napolina describes its chopped tomatoes as chunky; Mutti describes its Polpa as finely chopped. | For a sauce with visible tomato pieces, I would choose a chunky cut. For a more even texture, I would consider a fine cut and check its salt value separately. |
| Pack quantity | Count the meals you plan to cook before choosing a single 400g tin, a 4 x 400g pack or a larger multipack. | Several shared meals could use multiple tins; for one or two meals, I would rather check whether I can use the whole pack. |
| Leftovers | Read the opened-storage directions on the tin. Marks & Spencer says to transfer its standard chopped tomatoes to a non-metallic container, refrigerate and eat within 3 days; Tesco’s Napolina 4-pack listing says to empty, cover and refrigerate, then use within 2 days. | If a recipe uses only part of a tin, I want a plan for the remainder during the stay. |
Common buying mistakes
-
Reading “lower salt” as a claim on the pack
A low declared value and a comparative ‘reduced salt’ claim are different things. Comparing nutrition panels helps with the purchase, but does not establish what claim a product can carry.
Use salt per 100g to compare similar tins, and check the actual label if a ‘reduced salt’ claim matters to you.
-
Choosing texture without reading the nutrition panel
Mutti describes its Polpa as finely chopped and declares 0.30g salt per 100g; the Tesco Napolina chopped-tomato listing declares 0.10g per 100g. Texture alone does not tell you the salt value.
Choose the cut that suits the dish, then check the declared salt for that specific product.
-
Assuming opened tins have identical instructions
The stated opened-life differs between Marks & Spencer’s standard chopped tomatoes and the Napolina 4-pack listed by Tesco. A leftover portion may need using before the stay ends.
Follow the instructions on your tin and plan another meal for any tomatoes left after opening.
-
Relying on an older product listing
Retailers note that food information can change, so an online nutrition panel or storage direction may not match a later tin.
At purchase, read the current label for salt per 100g, ingredients and opened-storage directions.
Brand and product-line references
These examples describe particular tomato products and formats, not every tin sold under each brand.
M&S
Marks & Spencer lists standard and organic Chopped Italian Tomatoes in 400g tins.
- The standard tin declares 0.02g salt per 100g and gives a 3-day refrigerated opened-life instruction.
- The organic tin has a different declaration, 0.03g salt per 100g, and its own 2-day opened-life instruction; check which tin you have.
Tesco
Tesco Italian Chopped Tomatoes are listed as a 4 x 400g multipack.
- Tesco declares 0.09g salt per 100g for this multipack, which can be divided between several meals.
- Tesco advises shoppers to check the product label because food information may change.
Napolina
Napolina describes its chopped tomatoes as chunky and packed in tomato juice; Tesco lists a 4 x 400g pack.
- The Tesco 4-pack listing declares 0.10g salt per 100g and says to use refrigerated leftovers within 2 days.
- For a salt-led choice, compare that declaration with the other tins you are considering rather than relying on texture.
Mutti
Mutti describes Polpa as finely chopped tomato pulp for quick or longer cooking.
- The fine cut offers an alternative to chunkier chopped tomatoes when texture matters to the recipe.
- Mutti lists added salt and declares 0.30g salt per 100g for Polpa, so check that value against a lower-salt brief.
Sainsbury's
Sainsbury's grocery category lists own-label chopped tomatoes alongside Napolina and Mutti products.
- The category includes different tomato formats to consider for cottage meals.
- Compare the salt declaration on the particular own-label tin before treating it as a lower-salt option.

Frequently asked questions
Does a lower salt value mean a tin is labelled ‘reduced salt’?
No. A declared salt value lets you compare tins per 100g, but it does not by itself establish a comparative ‘reduced salt’ claim. Check the product label rather than applying that wording to any tin with a lower number.
Which of these named tins declares the least salt?
Among the named retailer and manufacturer listings compared here, Marks & Spencer’s standard Chopped Italian Tomatoes declare 0.02g salt per 100g. Its organic version declares 0.03g, Tesco Italian Chopped Tomatoes 0.09g, Napolina Chopped Tomatoes 0.10g and Mutti Polpa 0.30g per 100g. Read the current tin when buying.
Should I choose chopped or finely chopped tomatoes for cottage meals?
Choose according to the texture wanted in the dish, then compare salt separately. Napolina describes its chopped tomatoes as chunky and suited to thick sauces; Mutti describes Polpa as finely chopped and suitable for quick or longer cooking.
How long can I keep tomatoes left after opening a tin?
Follow the directions on that product. Marks & Spencer says to transfer its standard chopped tomatoes to a non-metallic container, refrigerate and eat within 3 days; the Tesco Napolina 4-pack listing says to empty, cover and refrigerate, then use within 2 days.
