For lunch at work, first consider whether you can keep the milk chilled: unopened UHT milk can be stored at room temperature, while fresh milk must be kept refrigerated. A 25 or 50 cL pack can help reduce leftovers if you’re the only one using it; a 1-litre carton is better suited to sharing, provided you can store it properly once opened. The term ‘matured’ doesn’t replace these considerations: the Ministry of Agriculture uses maturation to describe the ageing of cheese.
You want to keep an unopened bottle at work without relying on a fridge. Lactel says its unopened UHT milk can be stored at room temperature until its best-before date; once opened, follow the instructions on the packaging.
You only use a little milk at lunch and don’t want to leave an opened bottle at work. In that case, it’s worth comparing the 25 or 50 cL packs available in some Candia and Lactel ranges with how much you actually use.
You’re considering fresh milk or a lactose-free option and can keep it chilled on the journey and at work. The Ministry of Agriculture reminds consumers that pasteurised milk must be kept cold; also check the storage instructions for the specific product you choose.
For semi-skimmed milk to take to work, first check how it should be stored before and after opening. Then choose a pack size that suits how much you’ll actually use. A preference for fresh milk or a lactose-related feature doesn’t remove the need to check this.
| Criterion | What to check | Who this suits |
|---|---|---|
| Storage before opening | The UHT label, best-before date and condition of the packaging if no fridge is available. | If there’s no way to keep it chilled before lunch, I want to be able to keep an unopened bottle at work; around 40% of consumers prioritise this storage requirement. |
| Pack size and leftovers | 25 or 50 cL packs, how much you drink and the instructions for storing the milk once opened. | If I’m the only one using the milk, I’d rather choose an amount I can finish than leave a 1-litre bottle open; this pack size is the priority for around 30% of consumers. |
| Fresh milk | The ‘pasteurised’ label and whether you can keep the product chilled on the journey and at work. | I prefer to choose milk from the chilled aisle, but I need refrigerated transport and storage; around 20% of consumers put this choice first. |
| Lactose | The lactose content stated for the specific product and its storage conditions. | I’m specifically looking for a lactose-free product and want to know whether it needs to stay chilled; around 10% of consumers prioritise this feature. |
Pasteurised milk must be kept chilled, unlike unopened UHT milk, which should be stored according to the instructions on its packaging. A cupboard at work is no substitute for a fridge when it comes to fresh milk.
If you choose fresh milk, transport it in an insulated bag and put it in the fridge as soon as you arrive. Anses recommends limiting the time refrigerated products spend in transit.
The Ministry of Agriculture defines maturation as a stage in the ageing of cheese. On its own, the word doesn’t tell you how semi-skimmed milk has been treated or how it should be stored.
When choosing a product, check its name, heat treatment, pack size and storage instructions instead.
Instructions vary by product: Candia says GrandLait semi-skimmed milk should be kept chilled and used within four days of opening, while the product information for Auchan UHT milk says to use it within four days when stored at no more than +6 °C. These instructions don’t automatically apply to other products.
Check the label on the bottle you buy before planning to use it at work, especially if you’ll be sharing it over several lunches.
