The moisture of buds decreased down to 80 % for both treatments. However, no
signifi cant changes were recorded in Chl
a
, Chl
b
, and TChl of MAP-treated broccoli
whereas for control samples about 50 % of Chl
a
(1.0 pmol/g of DW), Chl
b
(0.4
pmol/g of DW) and TChl (1.4 pmol/g of DW) were lost. In samples treated with AM,
the protein level amounted to 85 mg/g of DW by 96 h that is lower by 20 % than the
initial level.

Caulifl ower
Simon et al. (
2008
) used two different fi lms (non-perforated PVC and OPP) to gen-
erate atmosphere modifi cation for caulifl owers stored at 4 °C and 8 °C for 20 days.
Samples from PVC and PP bags had lower shear force values compared to control
(2,520, 2,480 N for PVC and PP, respectively). Weight losses were greater for cau-
lifl owers in PVC fi lms than those stored in PP (2 and 0.61 % and 2.3 and 0.61 % at
4 °C and 8 °C, respectively). Samples in PP bags were given higher appearance
scores.
Eight varieties of caulifl ower (Abruzzi, Dulis, Casper, Serrano, Caprio, Nautilus,
Beluga and Arbon) were stored under MAP (microperforated PVC, P-Plus 120, 160
and 240 fi lms) at 4 °C for 25 days Sanz et al. (
2007
). The high initial microbial
count was one of the reasons that samples from the Serrano variety in PVC fi lm
reached the microbial legal limit (7 log CFU/g) in only 3 days. P-Plus fi lm proved
to be the most suitable fi lm for maintaining sensory attributes in Abruzzi, Dulis,
Casper and Serrano varieties.

Mung bean
Chlorine dioxide (dipping in 100 ppm ClO
2
solution for 5 min) was applied in com-
bination with MAP (passive MA with AVR 008 fi lm used, vacuum and A MA with
100 % CO
2
and 100 % N
2
) in mung bean sprouts during storage at 5 ± 2 °C for 7
days. Treatment with ClO
2
under vacuum, N
2
gas, and CO
2
gas led to reduction of
total mesophiles (7.34, 7.51 and 7.22 log
10
CFU/g, respectively) at the end of stor-
age. The use of ClO
2
as a disinfectant in conjunction with high CO
2
MAP was suc-
cessful in inhibiting microbial growth (Jin and Lee
2007
).
