Families planning school-night meals
A cupboard tin can become the base for pasta sauce, soup, chilli or stew. A plain product lets you decide what else goes into the dish, including sweetening ingredients and seasoning.
Who is this for?
Shoppers checking sugar labels
If you are comparing reduced-sugar and no-added-sugar wording, read the ingredients alongside the nutrition panel. A figure for total sugars alone does not tell you whether sugar was added.
Cooks who prefer to add their own salt
Compare salt per 100g as well as sugars. A tin described as having no added sugar need not also be a no-added-salt product.
What to check before buying
Start with the ingredients and the texture your recipe needs, then compare nutrition figures on the same per-100g basis.
| Priority | What to check | Your needs |
|---|---|---|
| Added sweeteners | Read the ingredient list for sweetening ingredients. Check any no-added-sugar wording against the product you are buying. | I want a plain base for pasta sauce, soup or chilli and would rather decide for myself whether to add sweetness. The NHS distinguishes sugars in chopped vegetables from sugars added to foods. |
| Reduced-sugar wording | Identify the similar product used for the comparison, then compare their sugars per 100g. Legislation published by legislation.gov.uk treats reduced sugar as a comparative claim, distinct from no added sugar. | A reduced-sugar label is useful to me only when I can see what it is being compared with; it does not answer whether sweetening ingredients were added. |
| Salt | Compare salt per 100g and check whether salt appears in the ingredients. Ocado lists no added salt for Biona and Mr Organic chopped tomatoes; the Joybuy listing for Mutti finely chopped tomatoes includes salt. | If I will add stock, cheese or other seasoning to the finished dish, I want to know how much salt the tomato base already contains. |
| Tomato texture | Check whether the tin contains chopped tomatoes or finely chopped pulp. Match the format to the finished texture and cooking method. | Chunkier tomatoes suit the sauce I am making tonight; for a longer-cooked dish, I may prefer the finer texture of Mutti Polpa, which Mutti describes as suited to long cooking. |
| After opening | Read the storage and use instructions on the particular pack. Keep any leftovers as its label directs. | When a recipe uses only part of a tin, I need to know how to store the remainder and when to use it. |
Common buying mistakes
-
Reading reduced sugar as no added sugar
These answer different questions: reduced sugar compares a product with a similar one, while no added sugar concerns ingredients used for sweetening. Neither wording means that plain tomatoes contain no naturally occurring sugars.
Check the ingredients first if avoiding added sweeteners is your aim. Use the per-100g sugars figure to compare products on a consistent basis.
-
Comparing sugars but overlooking salt
A lower sugars figure does not establish a lower salt figure. For example, Ocado lists 0.02g salt per 100g for Biona chopped tomatoes, while Joybuy lists 0.30g per 100g for Mutti finely chopped tomatoes, whose ingredients include salt.
Read both figures per 100g, particularly when you intend to add other seasonings to the meal.
-
Picking a flavoured product when the recipe needs plain tomatoes
Added ingredients may change how you season a sauce and what you need to check on its label. A prepared tomato sauce is not necessarily interchangeable with a tin of plain chopped tomatoes.
Choose the ingredient profile your recipe calls for, and read the current pack if allergens or other ingredients matter to your household.
-
Assuming every opened tin has the same use period
Instructions differ: the Joybuy listings for Napolina chopped tomatoes and Mutti finely chopped tomatoes state different refrigerated use periods after opening.
Transfer leftovers to a covered non-metallic container, refrigerate them and follow the instructions on the specific pack.
Brand and product-line references
These examples describe particular tomato products, not every tin made by each brand; compare the pack you intend to buy.
Mr Organic
Its Italian chopped tomatoes are described by Ocado as free from added sugars and salt.
- The Ocado listing reports 2.3g sugars and 0.03g salt per 100g.
- No added sugar does not mean that the tomatoes have no naturally occurring sugars.
Biona
Ocado lists Biona Organic Chopped Tomatoes as having no added salt or sugar.
- The listed figures are 3.0g sugars and 0.02g salt per 100g.
- Check the exact pack and ingredients when comparing it with another chopped-tomato product.
Mutti
Mutti Polpa is a finely chopped tomato pulp that Mutti describes as suited to longer cooking.
- The Joybuy listing for the 4 x 400g pack reports 2.8g sugars per 100g.
- Its ingredients include salt, and the same listing reports 0.30g salt per 100g; it is not a no-added-salt choice.
Napolina
Napolina chopped tomatoes offer a chunkier base for dishes such as thick sauces.
- The Joybuy listing for a 400g tin gives tomatoes, tomato juice and citric acid as ingredients.
- That listing does not describe the product as reduced sugar; check the label of the pack you choose rather than inferring a claim from the brand.
M&S
M&S Italian Tomatoes are a chopped-tomato product in tomato juice.
- The Marks & Spencer listing reports 2.5g sugars and 0.10g salt per 100g.
- Those figures describe this listed product, not every M&S tomato product; check the current pack when comparing variants.
Joybuy tomato options
These two multipacks cover a chopped-tomato base and a finer tomato pulp for school-term cooking. Compare their current labels if a particular sugar or salt figure matters to your recipe.

Napolina Chopped Tomatoes 4 x 400g
A chopped-tomato multipack for sauces, soups and stews when you want a plain cooking base. Check the current pack for its ingredients and per-100g sugars and salt before comparing it with other tins. The product instructions say to transfer leftovers to a covered non-metallic container, refrigerate and use within two days.
No image available
Mutti Finely Chopped Tomatoes 4 x 400g
The finer texture is an option for longer-cooked tomato dishes. The Joybuy listing gives tomato 99.8% and salt as ingredients, with 2.8g sugars and 0.30g salt per 100g. Because salt is added, compare that figure with other tins if you want to control the dish’s seasoning.
Frequently asked questions
Does the sugars figure on plain chopped tomatoes mean sugar was added?
No. The figure reports sugars in the product, not their origin. Check the ingredient list for sweetening ingredients; the NHS also distinguishes sugars in chopped vegetables from sugars added to food.
What should I check on a reduced-sugar tin?
Look at the similar product used for the comparison and the sugars per 100g. Reduced sugar is a comparative claim, so it does not by itself tell you whether sweetening ingredients were added or whether the tin suits your recipe.
Does no added sugar mean sugar-free tomatoes?
No. Tomatoes can still contribute sugars to the total shown on the nutrition panel. For example, Ocado lists 3.0g sugars per 100g for Biona Organic Chopped Tomatoes while describing that product as having no added sugar.
How should I keep tomatoes left over from an opened tin?
Follow the instructions on that product’s pack: transfer leftovers to a covered non-metallic container, refrigerate them and use them within the stated period. Joybuy’s listed instructions give two days for Napolina chopped tomatoes and five days for Mutti finely chopped tomatoes, so do not apply one tin’s period to another.
What should I check for a child with an allergy or dietary requirement?
Read the current pack’s ingredients and allergen information before serving it, including any added ingredients in a flavoured tomato product. Check its storage instructions too if you plan to use the tin across several meals.
