respectively, after the 3.5 min RF treatment (at the end of the first step of the process).
The maximum albumen temperature was well below 57 C, the temperature at which the foaming power of albumen begins to rapidly decline .
Furthermore, the maximum yolk temperature indicates that at least
some part of the yolk was at a temperature where the pasteurization holding time is estimated to be only 3.7 min (USDA, 1969). The
duration of the entire process was 23.5 min and resulted in a
reduction of E. coli of 6.5 log. By comparison, the reduction of E. coli
using just hot water for 60 min was 6.6 log.
