Why turn your breast milk into powder?
Every drop of breast milk is valuable, but freezers fill fast and space runs out. Turning your milk into a shelf-stable powder gives you more flexibility, longer storage life, and freedom to feed on your own schedule.
Freeze-drying is the gentle, lab-tested way Australian mums are now preserving their milk. It removes only water; keeping your milk’s nutrients, antibodies, and goodness intact.
How the process works
1. Collect and freeze your milk
Express as normal, label each bag with the date and volume (if you want to), and freeze flat for easy storage. When you’re ready to convert your stash, we’ll send you a medical-grade cooler kit so your frozen milk arrives safely at our HACCP-certified facility.
2. Receive your cooler kit
Our kits include insulated panels, instructions, and return courier labels. You simply pack your frozen milk and hand it to the driver; no complicated steps, no dry ice or ice-bricks required.
3. Freeze-drying begins
At Nourishy, your milk stays frozen from start to finish. In our remotely monitored facility, we use vacuum pressure to remove the water molecules while keeping your milk below body temperature. This process is far gentler than any heat-based drying method.
4. Testing and packaging
- Individual processing: Your milk is processed separately with barcode tracking.
- Water-activity (aw) testing: Confirms the powder’s long-term shelf stability. Along with our shelf-stability tested packaging.
- HACCP safety checks: Every batch passes through rigorous quality controls.
5. Return shipping
Once complete, your milk powder is sealed into pouches (either Single-Feed, Multi-Feed or Combo options) and shipped back to you. Each pouch is labelled with your order ID for full traceability.
What makes freeze-dried breast milk different?
- Convenience: Store in the pantry instead of the freezer (safeguard from power outages!)
- Longevity: Up to three-year shelf life when sealed and kept at room temp.
- Flexibility: Mix only what you need, reducing waste.
- Travel-ready: Light, compact, and TSA-friendly for flights.
Unlike traditional freezing, freeze-drying stops the lipase enzyme responsible for flavour changes, keeping your milk’s natural taste locked in.
How to reconstitute the powder
Each pouch includes a simple reconstitution guide matched to your milk volume. In general:
- Add warm, sterile water to the indicated line.
- Swirl gently until fully dissolved.
- Serve immediately or store the reconstituted milk in the fridge for up to 24 hours.
Once reconstituted, it’s your milk again; same nutrients, just in a more flexible form.
Common questions
Can I turn older frozen milk into powder?
Yes, provided it’s been stored safely. Freeze-drying can’t reverse taste changes already present, but it stops further flavour shifts and stabilises the milk for the long term.
Will freeze-drying change the nutrition?
No. It removes only water, leaving the natural fat, protein, and carbohydrate content intact.
How long does it last?
When sealed in Nourishy pouches and kept in a cool, dry place, your milk powder can remain stable for up to three years.
Can I mix sessions or combine bags?
Yes. Most mums combine by day or pumping session. We process the milk exactly as received; every order remains separate and traceable to you.
Is freeze-dried milk still considered breast milk?
Absolutely. It’s your milk, simply without the water. Once reconstituted, it returns to its original state with the same nutritional profile.
