Freeze-drying is a low-temperature dehydration process in which the product is frozen, usually at temperatures as low as -50°C, and the ice is then removed by sublimation in a vacuum chamber. This process lasts up to 50 hours and allows for complete dehydration, preserving most of the food’s original constituents while maintaining excellent product quality and allowing it to be rehydrated. This is the technique used to dehydrate your breast milk and turn it into powder form, which has all the components of the breast milk aside from the water. Without the presence of air and water, the milk can be stably packaged and stored and does not require refrigeration. This is a new service we offer to mothers so that they can preserve their milk longer and use it more conveniently. When it comes to the use of breast milk, our service provides a series of advantages.

Frequently ask questions
Who am I?
My name is Maja and I am the mother of little Luka. Our breastfeeding journey has been challenging and we have had our ups and downs. Since we were having trouble storing breast milk (we had limited freezer space, and due to the Covid pandemic, we were also required to store plenty of food), I was looking for alternatives to preserve my liquid gold. That’s how I found out about the possibility of turning my liquid milk into powder form and the story of Mlekec.si began.
How long does the order take?
Once your reservation is confirmed, the processing time may vary depending on the waiting list, which is currently 1–3 weeks. The customer will always receive updated waiting list information before their order is confirmed.
Where is the Mlekec.si service available?
At this stage, we can pick up your frozen breast milk at your address in Ljubljana, Maribor or Celje (and surroundings). However, we are also happy to offer our service to other customers if you can organize the shipment of your frozen milk yourself (you can either bring it to us personally or find a courier that transports frozen goods).
Does the freeze-drying process stop lipase activity?
Yes. The lipase enzyme is made inactive by the freeze-drying process. Mothers who are concerned about changes in the flavour or taste of their milk can stop further lipase activity by freeze-drying, however, reversing the degradation that has already occurred is impossible. We recommend freeze-drying breast milk that has not been stored in the freezer for more than three months.
Why is freeze-drying my milk better than freezer storage?
Freeze-drying preserves the breast milk much longer. It is also particularly useful when freezer storage is impractical or impossible due to lack of freezer space, travel, moving or to protect against power outages. Given the effort and time a mother puts into storing milk for later use, many want to use the milk that they have worked so hard to save.
Is there a minimum/maximum quantity of milk per bag that I can prepare and freeze?
Yes, do not express, freeze and store more than 120ml of milk in a single breast milk bag.
