posted on 03.03.2011, 11:26 authored by S. Pispan, Christopher Hewitt, Andy StapleyAndy StapleyThe survival of mid-exponential and the early-stationary E. coli K12 and L.
acidophilus were investigated when spray drying and outlet air temperatures of 60, 70,
80, 90 and 100°C. The results showed that the early-stationary cell of both cultures had a
greater heat resistance than the mid-log cell in every drying temperature. The best
survival rate was found when spray drying at temperature lower 80°C and it is showed
that L. acidophilus is stronger than E. coli K12 (irrespective of the growth phase).
