White
asparagus

AMAP
40 %/60 %
CO 2 /N 2

PP fi lm of OTR: 44 and
CO 2 TR: 142 mL/m 2 day atm.

Samples were initially
peeled and cut, washed
in a chlorine solution
of 30 ppm, immersed
in an acidic bath of
citric acid 0.2 % and
ascorbic acid 0.1 %,
drained, packaged
under MAP and
pasteurized

4, 10, 20 and
30 °C—17 days

Shelf life was correlated to
storage temperature and
was 84 h at 30 °C, 5 days
at 20 °C, 6 days at 10 °C
and 13 days at 4 °C. No
Clostridium spp. was
detected on samples stored
at 4 and 10 °C. LAB
populations on the time of
rejection were (7.15, 5.85,
5.31 and 5.58 for samples
stored at 4, 10, 20 and
30 °C, respectively)

Asparagus
( Asparagus
offi cinalis
L .)
UC-157-F1

PMAP OPP fi lm with OTR:

14,000 mL/m 2 day atm. and of
35

1. 2 °C for 25 days
2. 2 °C for 5 days and
then at 10 °C for the
remaining days

MAP and refrigeration at
2 °C had the best results in
preserving asparagus
(2.1 %, 70.7 mg/100 g for
weight loss and vitamin C
content on the 33rd day),
increasing its shelf life by
12 days compared to
control and by 6 days
compared to samples
stored at 10 °C
