We Test Every Order
Milkify originally developed the 3-year expiration benchmark for freeze-dried breast milk based on our proprietary critical control limits.
Before any order leaves our facility, it passes a final quality control check using a laboratory-grade water activity meter — measuring the precise moisture level of the finished powder. This isn't a spot check or a batch sample. Every single order is tested individually.
Why does it matter? Water activity is the critical determinant of shelf stability. Confirming that moisture has been removed to exacting standards is what allows us to stand behind a shelf life of up to three years — no refrigeration required when stored properly in a cool, dry place.
It is the last step in our process, and one of the most important.
