Abstract:
Human milk confers protective, nutritive developmental, anti-inflammatory, growth
and immunomodulatory factors. The current recommendations are that the mother’s
own milk can be used first, and when breast feeding is not possible expressed breast milk
should be given to the baby. However, proven concerns about the safety of donor milk
have led neonatologists to pasteurization.
PCMC and ASTI jointly developed the first microprocessor controlled table top pasteurizer suitable for a Neonatal Intensive Care Unit or for the individual working mother.
This pasteurizer was found to provide precise well controlled stable temperatures. At
59°C encoded temperature, for 25 minutes, all bacterial colonies including Pseudomonas
(7x10*col/ml), Klebsiella (15x10? col /ml), Enterobacter (5x10° col /ml), E coli (100/ml) and
Constaph (8 x10* col/ml) were completely destroyed at the end of the pasteurization.
There was preservation of 84% of IgA.
