Gamma irradiation
at a dose of 0.15,
0.3, 0.6, 0.9 kGy.
Inoculation with
Escherichia coli
(10
6
CFU/g)
4 ± 1 °C—50 days
Irradiation (0.15 kGy
dose) and subsequent
AMAP or PMAP
storage led to a 3 and
4 log reduction of
E.
coli
population on
day 1 for PMAP and
AMAP samples,
respectively, but a 3
log CFU/g
population was
detected on day 7.
Doses
≥
3 kGy and
AMAP storage led to
complete eradication
of
E. coli
for the
whole storage period
of 50 days
Disinfection with
irradiation and
storage under
AMAP are a useful
combination for
preserving quality
of carrots
