Dipping into a
hydro- alcoholic
solution
(30 % v/v
in ethanol).
Coating into a

(4 % w/v) water
solution and

4 °C—19 days Mesophile load

of coated samples
in PMAP and
AMAP remained
stable (3 log CFU/g)
until the seventh
day and then
increased
up to 5.6 log
CFU/g. Psychro-
phile load
of coated samples
was lower under
AMAP compared
to PMAP (4 and 5
log CFU/g for
AMAP and PMAP
samples,
respectively, at the
end of storage
period). No Entero-
bacteriaceae load
was detected on

Shelf life of
uncoated samples
was limited to 2
days due to poor
sensory attributes.
Shelf life of coated
samples stored
under AMAP and
PMAP was 14.99
and 13.87 days,
respectively
