Freeze drying breast milk is a process that removes the water content from frozen breast milk, preserving its nutritional properties and allowing for long-term storage. This method provides convenience for breastfeeding mothers who want to store their milk without refrigeration. The freeze drying process involves sublimation, where the water in the breast milk transitions from a solid to a gas without going through the liquid phase. This helps to maintain the integrity of the nutrients and antibodies present in breast milk. The resulting freeze-dried breast milk is transformed into a fine powder, which can be easily reconstituted by adding water.

Key Takeaways:

  • Freeze drying breast milk preserves its nutritional properties and allows for long-term storage
  • The process involves sublimation, maintaining the integrity of nutrients and antibodies
  • Freeze-dried breast milk is transformed into a powder and can be reconstituted with water
  • Convenient for breastfeeding mothers who need to store and transport breast milk
  • Provides a reliable solution for ensuring babies receive optimal nutrition

Understanding the Freeze Drying Process of Breast Milk

When it comes to preserving breast milk, the freeze drying process plays a crucial role. Understanding the science behind sublimation, the maintenance of nutritional integrity, and the journey from liquid to powder will shed light on how this process works.

The Science Behind Sublimation

In the freeze drying process, sublimation is the key phenomenon that occurs. Sublimation refers to the transition of a substance directly from a solid to a gas state without going through the liquid phase. In the case of breast milk, sublimation allows for the removal of water content while preserving the nutritional properties and antibodies present in the milk.

Maintaining Nutritional Integrity

Freeze drying breast milk ensures that the vital nutrients and antibodies remain intact. The low temperature in the vacuum chamber prevents the degradation of these essential components, resulting in a freeze-dried powder that retains the nutritional qualities of the original breast milk.

The Journey from Liquid to Powder

The freeze drying process involves several steps that transform liquid breast milk into a fine powder. First, the frozen breast milk is placed inside a vacuum chamber cooled to a very low temperature. The removal of air from the chamber creates a deep vacuum environment, and sublimation takes place. The ice crystals in the breast milk turn into water vapor and are drawn out of the milk in this process. As a result, approximately 99.9% of the water content is removed, leaving behind a freeze-dried breast milk powder. This powder is then carefully packaged in airtight bags to protect it from moisture, oxygen, UV light, and other contaminants.

Freeze dry breast milk: Advanced Techniques for Longevity

To ensure the longevity and quality of freeze-dried breast milk, advanced techniques are utilized, including:

Testing and validation to ensure all water is sublimated from breast milk solids. 

Packaging the freeze-dried breast milk powder using sterile techniques inside an ISO5 cleanroom workstation.

Final quality control checks, such as measuring the water activity of the powder to ensure shelf stability for 3+ years.

Vacuum packaging the powder in high-barrier mylar bags to protect it from moisture, oxygen, UV light, and other contaminants.

These advanced techniques help to extend the shelf life of freeze-dried breast milk and preserve its nutritional integrity, ensuring that it remains a safe and convenient option for breastfeeding mothers.
