People comparing salt figures
A reduced-salt claim describes a comparison with a particular standard recipe. If salt is your deciding factor, the nutrition panel lets you compare different tins per 100g and per serving.
Who is this for?
People packing lunch for one
A smaller tin can match one lunch without leaving opened beans to carry home. Essential Waitrose offers a 220g can; the Tesco and Sainsbury’s tins discussed here are larger, two-serving formats.
Groups sharing a picnic
A larger tin can be portioned between eaters. Check the salt in each intended serving, and plan how any opened beans will be kept chilled rather than leaving the remainder in the can.
What should you check?
Choose the portion first, then compare nutrition figures on the same basis and plan for anything opened before or during the picnic.
| Priority | What to check | Your needs |
|---|---|---|
| Salt amount | Read salt per 100g, then salt in the portion you will eat. Tesco lists 0.29g per 100g and 0.60g per half-can; Essential Waitrose lists 0.30g per 100g and 0.66g per can, according to their product pages. | I want to compare tins of different sizes without mistaking a reduced-salt claim for the amount in my lunch. |
| Portion and leftovers | Match the tin to the number of eaters. Essential Waitrose offers a 220g can; Tesco’s 420g tin and Sainsbury’s 400g tin list half-can servings. Check the opened-can storage instructions. | For lunch on my own, I would rather open only what I can use. If we are sharing, a larger tin may fit the plan. |
| Food transport | Keep opened or prepared beans, and foods normally stored in the fridge, cold in a cool bag or box with ice or frozen gel packs. The Food Standards Agency warns that bacterial risk increases after four hours or more at 8°C and above. | I need a way to keep a prepared bean dish chilled on the journey and while it is served. |
| Sugar preference | Check sugars and salt separately per 100g. A no-added-sugar claim does not give the salt amount: the Waitrose & Partners listing for Heinz No Added Sugar beans states 0.4g salt per 100g. | If I am choosing a no-added-sugar recipe, I still want to know how its salt figure compares. |
Picnic planning mistakes
-
Assuming every reduced-salt tin has the same salt level
Each relative claim uses its own comparison recipe. The Tesco, Sainsbury’s, Essential Waitrose and Asda product listings give different salt figures per 100g.
Compare the nutrition panels per 100g first, then check the amount in the portion you intend to serve.
-
Opening a large tin without a plan for the remainder
A two-serving tin may leave beans to store after a solo lunch. The reviewed Tesco and Sainsbury’s labels instruct shoppers to transfer unused contents to a non-metallic container and refrigerate them.
Consider a smaller tin or share a larger one. If you will keep leftovers, bring a suitable covered container and keep them chilled.
-
Treating prepared beans like an unopened tin
Once beans are opened or made into a picnic dish, time and temperature matter. Food Standards Agency picnic guidance warns of increased bacterial risk after four hours or more at 8°C and above.
Pack prepared food with ice or frozen gel packs in a cool bag or box, and return leftovers to it promptly.
-
Reading “no added sugar” as a salt comparison
The Waitrose & Partners listing for Heinz No Added Sugar beans gives 0.4g salt per 100g; Tesco and Sainsbury’s list 0.29g per 100g for the reduced sugar and salt products discussed here.
Use the sugar claim to assess that preference, and read the separate salt figure before choosing.
Brand and product-line references
These figures refer to the named recipes and pack sizes, not to every baked-bean product from each brand; check the tin you buy for its current label.
Tesco
Tesco Reduced Sugar and Salt Baked Beans comes in a 420g, two-serving tin.
- Tesco Groceries lists 0.29g salt per 100g and 0.60g per 210g half-can.
- After opening, Tesco instructs shoppers to transfer unused beans to a non-metallic container, refrigerate them and use them within two days.
Sainsbury’s
Sainsbury’s Reduced Sugar & Salt Baked Beans is a 400g tin with a listed half-can serving.
- Sainsbury’s lists 0.29g salt and 2.8g sugars per 100g, with 0.59g salt per half-can.
- Unused beans need transferring to a non-metallic container and refrigerating; the product instructions say to use them within two days.
Asda
Asda Reduced Salt & No Added Sugar Baked Beans is a 410g tin for shoppers considering both claims.
- ASDA Groceries lists 0.34g salt per 100g and 0.70g per half-can.
- If you are eating alone, plan for the remainder of the tin and follow its opened-product storage instructions.
Waitrose
Essential Waitrose Reduced Salt & Sugar Baked Beans comes in a 220g can that may suit one lunch.
- Waitrose & Partners lists 0.30g salt per 100g and 0.66g per can.
- Eating the whole smaller can still means counting the salt in the whole can, rather than comparing serving figures from a half-can elsewhere.
Heinz
Heinz No Added Sugar Baked Beans is a separate option when the no-added-sugar recipe matters to your choice.
- The Waitrose & Partners listing describes it as having 25% less salt than standard Heinz beans.
- That listing gives 0.4g salt per 100g and 0.9g per half-can, so compare its absolute figures with other recipes.
M&S
M&S No Added Sugar Baked Beans is a no-added-sugar option rather than a confirmed reduced-salt comparison.
- Marks & Spencer lists 0.43g salt per 100g.
- Its opened-can instructions say to use a non-metallic container, refrigerate the contents and eat them within two days.

Picnic bean questions
Does an unopened tin need a cool bag?
An unopened ambient tin does not need chilling just because you are taking it to a picnic. Foods that you would normally keep in the fridge, including opened or prepared bean dishes, need to be kept cold; Food Standards Agency guidance recommends a cool bag or box with ice or frozen gel packs.
Can I take cooked baked beans to a picnic?
Yes, if you treat them as prepared food and keep them chilled during transport and serving. The Food Standards Agency warns that bacterial risk increases after four hours or more at 8°C and above; in extremely hot weather, its guidance says to use food that has been out of the fridge within two hours.
What should I do with beans left after opening a tin?
Transfer unused beans to a suitable covered, non-metallic container, refrigerate them and follow the particular tin’s instructions. Tesco, Sainsbury’s and Essential Waitrose specify use within two days; ASDA Groceries specifies four days for the reduced salt and no added sugar product. Those storage periods do not replace the need to keep picnic leftovers chilled.
Does “no added sugar” mean less salt?
No: sugar and salt are separate things to check on the nutrition panel. The Waitrose & Partners listing for Heinz No Added Sugar beans gives 0.4g salt per 100g, while Tesco and Sainsbury’s list 0.29g per 100g for their reduced sugar and salt recipes.
How do I compare salt in different tin sizes?
Start with salt per 100g to compare recipes on the same basis, then read the figure for the amount you expect to eat. Tesco Groceries lists 0.60g salt per half-can of its 420g reduced sugar and salt beans, while Waitrose & Partners lists 0.66g for a whole 220g Essential Waitrose can.
