With respect to psychrotrophic bacteria that are able to grow at
refrigerator temperature, the samples packaged with the OEO and
CITRAL films showed an inhibition of approximately 2 log at the
beginning of storage at 4 C. However, there was no measurable
effect after 8 days of storage, because psychrotrophic bacteria
counts increased at 8 C and they reached a stationary phase before
the day of analysis (data not shown).
