Why Freeze-Dry My Breast Milk?
The process of freeze-drying has been widely adopted and generally used in preserving food products. Milk banks in particular, do make use of this method to safely store and retain the nutrients of donors’ milk.
Research has shown that freeze-drying is one of, if not, the most effective way of human milk preservation. The process retains most of the breast milk’s nutrients and antimicrobial properties. The end product after the freeze-drying process leaves a shelf-stable powder that you can store for years! That beats freezing your breast milk which would last you, at best a year, not to mention that the properties degenerate over time.
Just think about all that freezer space you’ll save.
How Freeze-Dried Breast Milk Works
Freeze-drying basically puts food into a state of suspended animation. Moisture contents within are removed through a process called sublimation.
Your breast milk is placed on large racks inside a vacuum chamber where the temperature is lowered to below freezing, and then slowly raised. The water content from within transforms from a solid state (frozen) to gas (vapour), removing most of the weight while maintaining its structure.
The lower the moisture content, the longer the shelf life. Most (~97%!) of its all-important nutrients is preserved and retained, and can be reconstituted with water back to its original state.
Freeze
Your frozen breast milk is placed into chambers of even lower temperatures, deep freezing them.
Vacuum
Air pressure is dropped within the chamber with a powerful pump.
Dry
The longest part of the entire process. Warming and cooling cycles turn the ice crystals into vapour (sublimation), extracting almost all the water within. It takes 48 hours to complete this process.
Package
Packed individually, we vacuum seal our food-grade mylar bags to ensure shelf life stability without the usage of chemical reaction-based oxygen/moisture absorbers. Stored properly, they can last for up to 3 years! (Shelf life testing done by SGS)
How do we package your breast milk powder?
Freeze-dried breast milk powder is revolutionising breastfeeding for modern mums in Singapore. Using advanced freeze-dry machines and technology, frozen breast milk is transformed into milk powder and carefully packaged into individual customised packets. This innovative process accounts for each mum's unique breast milk water content, ensuring accurate reconstitution measurements and optimal nutrition for their babies.
These convenient packets make it easy to provide the perfect amount of milk solids for every feed, whether at home or on the go. With freeze-dried breast milk powder, Singaporean mums can now enjoy the flexibility of breastfeeding anytime, anywhere.
