The effect of thermal pasteurization, freeze-drying, and gamma irradiation on donor human milk

The availability of donor human milk (DHM) is currently limited by the volumes that can be thermally pasteurized and kept in long-term cold storage. This study assesses the application of freeze-drying followed by low-dose gamma irradiation of DHM for simplified, safe long-term storage. Solid-phase microextraction (SPME) GC-MS, SDS and native PAGE gel electrophoresis demonstrated that the overall changes in volatile and protein profiles in...
