packed under MA-A (5 kPa O2 + 15 kPa CO2) and MA-P (ambient air)
with P-Plus film, with values below 1 kPa. Under the superatmospheric
O2 conditions, the headspace O2 concentration decreased
from 80 kPa to 27 kPa on storage day 3. The values obtained for
the different MAP conditions suggest a high respiration rate of the
‘Blanca de Tudela’ artichoke slices. Gil-Izquierdo et al. (2002) classified
this cultivar with an extremely high respiration rate. Thus,
preparing artichoke heads by removing inedible parts led to a sharp
drop in O2 and an increase in CO2 and the highest atmosphere
modification was detected with a polypropylene film (P-Plus) (GilIzquierdo
et al., 2002; Giménez et al., 2003).
