Hosts keeping an eye on salt
If the menu includes a tomato-based main alongside stock, cheese, cured meat or bread, the tin’s declared salt figure helps you judge one part of the meal before seasoning the sauce.
Who is this for?
Hosts making a chunky sauce or stew
Chopped tomatoes suit a dish where visible pieces are welcome, such as a rustic pasta sauce or casserole. Napolina describes its chopped tomatoes as chunky and suited to thick sauces.
Hosts making a finer tomato sauce
A finely chopped pulp may suit a long-cooked sauce or oven dish. Mutti describes its Polpa as finely chopped, but its stated salt figure needs its own check; texture does not tell you the salt content.
What should you check?
Start with the recipe’s required quantity and texture, then compare salt per 100g on the exact tins you are considering.
| Priority | What to check | Your needs |
|---|---|---|
| Salt across the menu | Compare salt per 100g on like-for-like tins. Biona declares 0.02g, Mr Organic and M&S each declare 0.03g, and Napolina declares 0.10g per 100g on their respective product information. | I’m serving the sauce with ingredients such as cheese, stock or cured meat, so I want to consider their seasoning as well as the tomato base. |
| Label wording | Read both the ingredient list and nutrition panel. Biona and Mr Organic say no salt is added, yet each still declares a salt amount per 100g. | A “no added salt” statement is useful to me, but I don’t want to mistake it for a salt-free declaration. |
| Tomato texture | Check whether the tin contains chopped pieces, finely chopped pulp or whole plum tomatoes. Napolina describes chunky chopped tomatoes; Mutti describes a fine pulp. | For a rustic sauce, I want visible pieces. For a finer sauce, I’ll choose the cut separately from the salt figure. |
| Quantity and leftovers | Match tin size and pack count to the recipe. Check the chosen product’s instructions for transferring, refrigerating and using any remainder after opening. | I’d rather work out how many tins the guests’ portions require than open a multipack unnecessarily. |
What can catch you out?

Reading “no added salt” as “salt-free”
A tin can declare some salt per 100g even when salt is not added. Biona’s product information lists 0.02g per 100g and Mr Organic’s lists 0.03g.
Use the nutrition panel for a like-for-like comparison, and the ingredient list to check whether salt was added.
-
Choosing by salt figure without checking the cut
A tin of whole plum tomatoes is not the same format as chopped tomatoes, while finely chopped pulp gives a different texture from chunky pieces.
Decide what texture the dish needs, then compare the salt declarations of suitable products.
-
Seasoning before considering the rest of the dish
Stock, cheese, olives and cured meat can all contribute salt to a tomato-based meal.
Consider those ingredients when choosing the tomato base, and taste the finished sauce before adjusting its seasoning.
-
Leaving tomatoes in an opened tin
Post-opening instructions differ by product. M&S says to transfer its organic chopped tomatoes to a non-metallic container, refrigerate and eat within two days; Joybuy’s Napolina product information also says to transfer, cover and refrigerate the contents and use them within two days.
Check the tin you use and store any remainder according to its instructions.

No. Biona Organic Chopped Tomatoes say no salt is added but list 0.02g salt per 100g; Mr Organic Italian Chopped Tomatoes also say no salt is added and list 0.03g per 100g. Read the nutrition panel as well as the ingredient list.
