What is Flash Pasteurisation?

Flash Pasteurization is high temperature short time (HTST) pasteurization method used for heat treating donor milk.  The donor milk is heated up to 72° C for 15 seconds.  The rapid heating for a shorter time is less destructive of properties in breastmilk and so is considered to be superior to other forms of pasteurization.  One type of HTST is flash heating, which is used in the PiAstra system, which attempts to simulate flash pasteurization.
