Parents preparing tomato-based lunches ahead
If you cook pasta sauce, soup or a similar lunch in advance, the tomato texture needs to work in the recipe. Check the tin’s instructions before planning how to use any leftovers.
Who is this for?
Families checking for added sugars
Read the ingredients alongside the nutrition panel. As the NHS explains, the total-sugars figure includes sugars naturally present in vegetables, so it is not a separate measure of free sugars.
Shoppers comparing plain tomato tins
Compare sugars and salt on the same per-100g basis, then consider whether chopped pieces, finely chopped tomatoes or whole peeled tomatoes suit the lunch you are making.
What should you check?
Start with the nutrition panel and ingredients, then choose a tomato format that works in the recipe and check the instructions on the tin you buy.
| Priority | What to check | Your needs |
|---|---|---|
| Sugars and ingredients | Compare ‘of which sugars’ per 100g and read the ingredients for added sugars, honey, syrups or sweetened sauce ingredients. The NHS notes that naturally occurring vegetable sugars are included in the total. | I want a plain tomato base and a like-for-like total-sugars comparison, without treating the lower figure as a free-sugars measurement or a ‘reduced sugar’ claim. |
| Salt | Compare salt per 100g on the current labels. Mutti lists 0.30g for Polpa, Napolina lists 0.10g for Chopped Tomatoes, and the M&S product information lists 0.02g for Organic Italian Chopped Tomatoes. | If salt matters to my choice too, I want to check it alongside sugars rather than deciding from the sugars figure alone. |
| Tomato texture | Check whether the tin contains chunky chopped tomatoes, finely chopped pulp or whole peeled tomatoes. Napolina describes its chopped tomatoes as chunky; Mutti describes Polpa as finely chopped. | Visible tomato pieces work in some lunches, but I may need a finer texture for the sauce my child will eat. |
| Opened-tin storage | Read the current pack for transfer, refrigeration and use-within instructions. The Napolina 400g listing instructs shoppers to transfer opened contents to a non-metallic container, cover, refrigerate and use within two days. | When I make lunch ahead, I need to know how the remaining tomatoes should be stored and when to use them. |
Common buying mistakes
-
Calling the tin ‘reduced sugar’ because its total is lower
Two per-100g figures compare declared total sugars; they do not calculate free sugars or, by themselves, substantiate a comparative ‘reduced sugar’ claim. The NHS distinguishes naturally occurring vegetable sugars from free sugars.
Use the nutrition panels for a like-for-like comparison and check ingredients for added sugars and sweetened sauce ingredients.
-
Choosing by the nutrition panel without considering texture
Napolina describes its chopped tomatoes as chunky, while Mutti describes Polpa as finely chopped. Those formats may give different results in the lunch recipe.
Decide whether visible pieces suit the dish; if texture is important to your child, try the recipe at home before packing it for school.
-
Checking sugars but overlooking salt
The listed salt values differ among the products compared here: Mutti Polpa has 0.30g per 100g, Napolina Chopped Tomatoes 0.10g, and M&S Organic Italian Chopped Tomatoes 0.02g, according to their brand or retailer information.
Compare both nutrients per 100g on the current packs when both figures matter to your choice.
-
Relying on a webpage for opened-tin instructions
The M&S retailer information gives conflicting two- and three-day instructions after opening. A generic period is therefore a poor substitute for the wording on the tin in hand.
Follow the current pack’s directions for transferring, covering, refrigerating and using the contents.
A tin larger than your planned recipe needs may leave opened tomatoes that must be used within its stated period.
Brand and retailer references
These details describe the named products, not every tomato tin sold under each brand.
Mutti
Mutti describes Polpa as finely chopped tomato pulp for sauces.
- Mutti lists tomato (99.8%) and salt as ingredients, with 2.8g sugars per 100g.
- Mutti also lists 0.30g salt per 100g. Its referenced Polpa page is not a UK retail pack label, so check the tin being purchased.
Napolina
Napolina describes its Chopped Tomatoes as chunky tomatoes in tomato juice for thick sauces.
- Napolina lists 3.6g sugars and 0.10g salt per 100g for this product.
- The chunky format may not suit a sauce intended to have a finer texture.
M&S
The M&S Organic Italian Chopped Tomatoes listing provides another plain chopped-tomato option to compare.
- The Ocado listing reports 3.4g sugars and 0.02g salt per 100g.
- The retailer information conflicts on whether to use opened contents within two or three days; follow the current pack.
Tesco
Tesco’s grocery category lists own-label Italian chopped tomatoes alongside branded tomato products.
- An own-label tin can be included in a per-100g label comparison.
- Check the specific tin’s ingredients and nutrition panel before comparing it with the named products above.

Questions about sugars and storage
Does a lower sugars figure make a tin ‘reduced sugar’?
No. A lower ‘of which sugars’ value than another tin is a comparison of declared total sugars, not enough on its own to establish a ‘reduced sugar’ claim. Compare the same per-100g measure and read the ingredients when choosing tomatoes for a packed-lunch recipe.
Is ‘of which sugars’ the amount of free sugars?
No. The NHS explains that sugars naturally present in vegetables appear in the total-sugars figure but do not count as free sugars. Read the ingredients as well; the nutrition panel does not give a separate free-sugars figure.
How do the named plain tomatoes compare per 100g?
Mutti lists 2.8g sugars for Polpa, the Ocado listing reports 3.4g for M&S Organic Italian Chopped Tomatoes, and Napolina lists 3.6g for Chopped Tomatoes. These brand and retailer figures compare declared total sugars for those named products, not free sugars, texture or every tomato tin available.
What should I do with tomatoes left in an opened tin?
Follow the storage and use-within instructions on the tin you bought. The researched Napolina 400g listing says to transfer the contents to a non-metallic container, cover, refrigerate and use within two days; the M&S retailer information gives conflicting periods, making the current pack especially important to check.
