Nourishy Process Explaines
Step 1
Initial Quality Control and Tracking

Nourishy receives your frozen milk and does an initial QC check. Then, we label each of your bags with your name and a unique tracking ID.

Step 2
Precise Weighing and Logging

We weigh and log each bag of your milk. We record your notes (such as date frozen, time, diet, etc) for printing on your final custom packaging.

Step 3
SafeDry™ Freeze-Drying Process

Without touching it, we transfer your frozen milk to our proprietary freeze-drying pouches. These protect your milk from contamination while allowing water vapour to escape. Each bag remains separate during processing. Your milk is labeled with your name even while in the freeze-dryer.

Step 4
Clean Room Sterile Packaging

Working only on your order, a trained technician packages your freeze-dried breast milk using sterile techniques. Your milk never comes into contact with any equipment or utensils.

Step 5
Final QC & Dryness Measurement

Your technician measures the water activity ("dryness") of your breast milk powder to ensure it will remain safe for 3 years in our packaging. Your breast milk is now ready for its journey home!

How to Use Your Freeze-Dried Breast Milk

How to Use Your Freeze-Dried Breast Milk

We've got you covered with step-by-step guidelines on safely storing, rehydrating, and even incorporating your freeze-dried breast milk into solid foods, ensuring you make the most out of every precious ounce.

How Nourishy's Freeze-Drying Process Works

Nourishy's gentle freeze-drying process turns your breast milk into a convenient powder while keeping its vital nutrients intact! Here's how:


We remove water from your milk by turning it directly from ice to vapor.

Preserve Nutrition

This method keeps the milk's taste and nutritional quality.

No Thawing

We keep your milk frozen the entire time, ensuring its safety and integrity.

Steps for Freeze-Drying Breast Milk

Nourishy Process Step 2
1. Vacuum-Freeze

Your frozen breast milk is placed into a special chamber. A pump removes the air from the chamber, bringing it to a deep vacuum.

Nourishy Process Step 3
2. Sublimation

The milk's ice crystals turn into water vapour. In the vacuum chamber, the water vapour molecules are pulled out of the milk, leaving behind all other components as powder.

Nourishy Process Step 4
3. Package & Seal

Your breast milk powder is sealed in high-barrier mylar bags, protecting it from moisture, oxygen, UV light, and contamination. It’s now shelf-stable for 3 years without refrigeration.
