The Milk Room

Built for one thing: keeping your milk safe.

Our processes are rooted in food manufacturing and safety compliance, from how our facility was designed and built to how every piece of equipment is cleaned and maintained. We handle your milk the way we would want it handled for our own babies.

The OASIS Protocol™

Our internal framework for safety and integrity.

OASIS stands for Optimised Aseptic Safety & Integrity System.

Developed by Wonderbewbz, The OASIS Protocol™ is our internal framework for how we treat breast milk handling, traceability, quality checks and continuous improvement. It includes HACCP-aligned thinking as we use food safety principles to guide how we assess risk, improve systems and make decisions.

  • Milk handling
  • Traceability
  • Quality checks
  • Continuous improvement

The science

So what does freeze drying actually do?

It gently takes the water out of your milk and leaves everything else behind. What you get back is a powder you can mix with water, whenever you need it. Here's how it works.

Ice straight to vapour

Water leaves your milk without ever melting back into liquid. This is called sublimation.

The good stuff stays

No high heat and no additives, so your milk's nutrients and goodness are kept as they are.

No thawing in between

Your milk stays frozen the whole time it dries, so it never sits around as liquid.

Inside the freeze dryer

  1. 1

    Frozen even colder

    Your frozen milk goes into the freeze dryer and is chilled far below your home freezer, so every drop is solid ice.

  2. 2

    Vacuum and sublimation

    A pump pulls the air out of the chamber. With a little gentle warmth, the ice turns straight into vapour and is drawn away, leaving the milk solids behind.

  3. 3

    A final gentle dry

    The last traces of moisture are removed, leaving a light, dry powder that stays shelf stable without a freezer.

After this, your powder moves on to our quality checks and packing.

The process

What happens to your milk in the Milk Room.

Logged and tagged on arrival. Freeze-dried, one mama at a time. Checked twice before packing. Packed in an ISO-5 cabinet. Step 1 of 4
1

Logged and tagged on arrival.

Your frozen bags are checked in under your name and the last 4 digits of your mobile, and photographed at intake. From here, your milk is traceable at every step.

  • Photo-documented
  • Traceable end to end
2

Freeze-dried, one mama at a time.

We only ever process one mother's milk at a time, in our certified ISO-6 cleanroom, and it is freeze-dried into powder with no additives or preservatives. All equipment is cleaned, disinfected and sanitised before, between and after every batch.

  • Never mixed
  • Halal: separate equipment
3

Checked twice before packing.

Thermal imaging confirms your milk is thoroughly dried. Then a water activity test reading well below the food safety benchmark of 0.6, for shelf stability you can count on.

  • Thermal imaging QC
  • Water activity dryness test
4

Packed in an ISO-5 cabinet.

Final packing happens inside an ISO-5 laminar flow cabinet, which protects your powder from contamination right up to sealing. Each food-grade sachet is labelled with the exact water to add.

  • Custom packed to your size
  • Keeps up to 3 years unopened

Processing usually takes 7-20 days. We keep you updated on WhatsApp at every stage.

No compromising on safety
"My son was the first to try our breast milk powder. If I didn't trust our process enough to feed it to him, we wouldn't have launched."

As a mum, I understand how important it is to trust the process. That's how much we believe in the safety and quality of what we do.

Thank you for trusting us with your precious milk. We treat it with the care it deserves, just like we would for our own children.

Love, JoleneFounder & Mother

Control procedures

Transparency and control at every stage.

We process one mama's milk at a time to ensure absolute care and cleanliness. Before, between and after every batch, we clean, disinfect and sanitise all equipment to maintain the highest hygiene standards.

Every batch goes through a two-step QC check. First, thermal imaging confirms thorough drying. Then a water activity test must read way below 0.6 (food safety benchmark). This keeps your powder shelf-stable.

Packing is done in an ISO-5 laminar flow cabinet to protect your milk from contamination, preserving its purity from start to finish.

We regularly test the indoor air quality and the environment inside our Milk Room. This makes sure there are no airborne contaminants or gaps in sanitisation while your milk is being processed.

Our team goes through continuous, targeted training so every process stays effective, with safety and quality always at the forefront.

We keep thorough records of all training, breast milk handling policies, sanitation processes and quality checks, for complete transparency and accountability.
