Freeze drying is an effective method for preserving nutrients in breast milk. The evidence from various studies supports this conclusion:
Freeze drying preserves the nutritional properties, polyphenol-related functionality, and oxidative integrity of human milk, making it a suitable conservation method (Cortez & Soria, 2016).
The stability of freeze-dried human milk is higher than that of frozen or fresh milk, indicating that freeze-drying is a promising option for improving the preservation of human milk in banks (Lozano et al., 2014).
Combination techniques involving high-pressure processing and freeze-drying show great potential for preserving the nutritional value of human milk and ensuring microbiological safety (Jarzynka et al., 2021).
