Good results have been obtained with freeze-drying human milk, 100 g. of milk yielding about 12.5 g. of powder. Freeze-dried human milk had an electrophoretic pattern similar to the fresh milk, indicating that no denaturing of protein takes place during freeze-drying. There was no marked increase in the bacterial count of the product during 4 weeks' storage in closed vessels at room temperature. Six premature infants, fed the reconstituted freeze-dried milk for 2 weeks, followed by fresh human milk for a further 2 weeks, showed similar weight gains during both periods.
