There is nothing particularly surprising or complicated about the most common method of making stored milk safer than it would otherwise be. Holder Pasteurization, or HoP, aims to rid milk of potentially harmful germs by heating it to 62.5°C (145°F) for half an hour, and then cooling it back down to room temperature. This method is used by all of the Human Milk Banking Association of North America (HMBANA) milk banks, and differs from the high-temperature, short-time (HTST) pasteurization used in the dairy industry. But these days HoP has some newfangled competitors—potential alternatives to the tried and tested method—suggesting that the time is ripe for a full evaluation of HoP’s performance. This article is the first in a series of five on the topic. Starting at the beginning of this in-depth look, how good is HoP at its core mission: keeping pathogens at bay that could, in theory, find their way into milk and make it their home? Read More...
