Carrots
( Daucus
carota L .)
cv Nantes

BOPP/LDPE
bags

Immersion in
cold water (7 °C)
with 100 mg/L of
free chlorine at
pH 7.0 for 15 min.
Carrots were cut
into cubes

1 °C ± 1 °C
—21 days

ʲ -carotene

decreased
slightly during
storage

Total and fecal
coliforms,
anaerobic
mesophiles and
Salmonella were
absent in carrots
stored under all
studied conditions.
Psychrotroph
counts remained
≤

Vitamin C content
was retained in all
studied storage
conditions for the
whole experiment

(130.3-
132.8 mg/100 g)

Immersion in
alcohol, fl amed,
peeled, again
immersed in
alcohol and
fl amed and grated
with a sterile
grater. The carrots
were inoculated
with S. enteritidis
and Lactobacillus
sp.

4 °C—12 days S. enteritidis

survived under
all treatments being
unaffected by the
presence of
Lactobacillus .
LAB also grew
under all studied
conditions. The
acidic environment
created by LAB
population played
an inhibitory role
in Salmonella
growth

end of the
experiment

pH signifi cantly
