Why Freeze-Dry Your Breast Milk?
How Milkify Works
The entire process takes as little as one to two weeks (contact us if you have a deadline). Read on to learn more.
Milkify Receives Your Milk
Ship your frozen breast milk or drop it off to one of our facilities. Every bag is individually weighed, logged, and tracked.
Freeze-Drying Your Milk
We freeze-dry your breast milk using our contact-free process, ensuring your milk never touches our equipment. Your milk is labeled at all times, even while in the freeze-dryer.
Safe, Long-Term Packaging
After QC testing, we package your freeze-dried breast milk into ready-to-use pouches that last for 3 years on the shelf.
Consume & Enjoy Your Milk
Add water to make a bottle, or add your freeze-dried breast milk powder directly into your baby's solid foods!
Frequently Asked Questions
Shipping kits are typically sent 2-3 business days after the order is placed. The turnaround time once we receive your milk is between 1-3 weeks. Milkify Express services come with rush shipping (all overnight) and expedited processing (guaranteed 5-7 day turnaround).
Please contact us after placing your order if you have a deadline coming up - we are a concierge service and will do everything we can to make sure we are working on your schedule!
We are happy to work around travel timelines or to help when moving (different shipping addresses) are a concern - just let us know via email at email@example.com or contact us before or after placing an order.
If timing is not an issue for you, we will process your milk in the order that it was received. You can always track the status of your order using our tracking system here and you will receive email updates when we receive your milk, when your milk is processing, and when it has been shipped back to you!
Our service is available in all 50 U.S. states (including Hawaii and Alaska) and Canada. We send you everything you need to safely ship your milk - including a medical-grade cooler and overnight shipping label. No dry ice or ice packs needed! We only ship frozen milk via Priority Overnight (shipments arrive at 10:30am the day after you ship).
We also accept drop-offs directly to our Houston, TX facility and Irvine, CA drop-site.
We will freeze-dry any milk that you would like to save. It's your milk, and your choice! However, we advise following the CDC recommendation of 12 months max freezer time from a safety standpoint.
- Your milk must be stored in a pre-sealed and pre-sterilized, single-use lactation bag (or hospital provided tube). We are not able to accept milk stored in bags not specifically approved for use as lactation bags (no Ziplock-type bags). Please note that we do not accept glass bottles or jars, or silicone storage bags.
- The bags you send must be intact (no rips or tears) and should be free of dirt and debris on the outside.
- Your milk must be frozen solid, and not previously thawed.
Freeze-drying can help in many situations with milk that tastes different after freezer storage. About 90% of our clients have told us that freeze-drying improved the taste of their high lipase milk. However, it is hard to predict whether the process will for sure make the milk palatable again because it depends on how much lipase activity has already occurred in the milk, and your infant's taste preference also plays a role! The lipase enzyme can remain active during freezer storage, but it is inactivated by the freeze-drying process. For moms concerned about high-lipase, freeze-drying may stop any further lipase activity, but it cannot undo any degradation that has already occurred. If your infant refuses your frozen milk, freeze-drying may help - but we recommend doing a small 'test' batch first, if this is a concern.
We have many quality control checkpoints in place to keep the milk separated. First - each customer's order is processed one at a time. This includes the receiving, the freeze-drying, and the packaging steps.
Second - we track each bag individually. Each bag you send in is labeled with your name and a unique tracking code, and we use this to track each bag of your milk from start to finish. Your milk is freeze-dried inside of a specialized freeze-drying pouch - this patent-pending design allows water vapor to escape while protecting your milk from contamination at any point in the process (we do NOT pool milk on trays for processing). This means that even while in the freeze-dryer, all of your milk is labeled with your name!
With this system, we can include the expression date and any other information you recorded on the custom label provided on each pouch of breast milk powder you receive back (if you did not record any notes, that's okay too! In this case the notes section on your label will be left blank).
During the freeze-drying process, the weight of the milk is reduced by about 90%, and the only thing that freeze-drying removes is the water. When you add the correct amount of water back to your powder - the volume is the same as it was before freeze-drying.
Therefore, if you send in 300 fl. oz. frozen milk, the powder you receive back will remake 300 fl. oz of milk once water is added.
The instructions on the back of the bags you receive back tell you exactly how much water to add back to get the same consistency as the original milk.
Freeze-drying is a very gentle process, and results in complete retention of the macronutrients (proteins, fats, carbs, or overall caloric content) in breast milk. Various human milk donor banks world-wide are implementing this process as an improved method of storage for donated breast milk. We now offer nutritional testing as an add-on to our service in which we measure the calories, carbohydrates, fats, and proteins in your milk using the Miris, an FDA approved human milk analyzer. When rehydrated according to the instructions on the custom label of each pouch - the rehydrated breast milk will have the same nutritional composition as before freeze-drying.
