If you’re buying milk ahead of an Italian evening, semi-skimmed UHT milk that can be stored at room temperature meets your pre-opening storage needs, as stated on the Auchan and Carrefour product pages for the products mentioned. If filtration is essential, check that the specific product is explicitly labelled ‘filtered’ or ‘microfiltered’: Anses treats microfiltration as distinct from UHT processing. Then choose a pack size based on how much you’ll need to open, and follow the storage instructions once opened.
You want to buy the milk before the day of your get-together without making room in the fridge for unopened cartons. The Auchan product pages mentioned say that the cartons can be stored at room temperature before opening, in line with the packaging instructions.
You’ll be using milk in one or more dishes and want a pack size that suits the quantities you need. How long an opened carton keeps varies by product, including those listed by Auchan, Candia and Lactel.
You’re looking for the milk you choose to be clearly labelled ‘filtered’ or ‘microfiltered’. The UHT designation alone doesn’t confirm this, so check the packaging for the exact product.
If you’re planning to buy early, first check how unopened milk should be stored. Chilled, pasteurised semi-skimmed milk isn’t suited to the same pre-event storage needs. Whatever you choose, work out how much you’ll need to open and read the instructions for that specific product.
| Criterion | What to check | Who is it for? |
|---|---|---|
| Storage before the evening | The UHT designation and storage instructions before opening, including whether the carton can be kept at room temperature. | I want to buy the milk in advance without refrigerating unopened cartons; this would be the priority for around 46% of consumers. |
| Pack size and opened cartons | The volume per carton, the number of cartons and how long each one can be kept chilled after opening. | For several dishes, I’d rather open only the amount I need and use the rest within the stated time. Around 36% of consumers would prioritise choosing a suitable pack size. |
| Filtration labelling | A clear ‘filtered’ or ‘microfiltered’ label on the exact product, rather than assuming this from UHT processing alone. | If I’m specifically looking for filtered milk, a long shelf life isn’t enough to meet my needs; this would come first for around 18% of consumers. |
The Auchan and Lactel product pages describe the products mentioned as UHT-sterilised milk. Anses considers microfiltration a process distinct from UHT treatment, so one cannot be inferred from the other.
If filtration is a deciding factor, look for ‘filtered’ or ‘microfiltered’ on the packaging of the exact product.
Once opened, storage times vary by product: the instructions mentioned give 5 days for Auchan UHT 8 × 1 L, 4 days for Candia GrandLait and 3 days for the Lactel product in question. Each should be kept chilled as stated on its label.
Work out how many cartons you’ll need for your dishes, then open the rest only when you’re ready to use them.
Auchan notes that ingredients may vary depending on the online grocery service and purchase date. The product page you consult and the version you receive may therefore not show exactly the same information.
Check the packaging you receive for the product designation, ingredients, storage instructions and any feature that’s essential to your choice.

For several dishes, the 50 cl cartons let you open them as you need them.
Pack size: 6 × 50 cl. If filtration is essential, look for an explicit label on the packaging of this product.
Yes, before opening, if the packaging for the product you’ve bought says it can be stored at room temperature. This applies to the products mentioned by Auchan and Carrefour. Auchan advises keeping them away from heat and moisture.
Follow the storage time and temperature shown on its own label. The product pages mentioned recommend 5 days at a maximum of +6 °C for Auchan UHT 8 × 1 L, 4 days at a maximum of +6 °C for Candia GrandLait, and use within 3 days at a maximum of +6 °C for the Lactel product in question. The Ministry of the Economy reminds consumers to follow the manufacturer’s storage recommendations once a product has been opened.
No. The UHT label alone doesn’t confirm microfiltration. Anses treats these processes separately in its technical opinion, so if filtration matters to you, look for a clear label on the specific product.
Not necessarily. Auchan says that ingredients may vary depending on the online grocery service and purchase date. Check the label on the product you receive if its ingredients or a specific feature will affect your choice.
