Sammendrag

Modified atmosphere packaging (MAP) may inhibit undesirable quality changes
of fruit and vegetables. The aim of this experiment was to evaluate the effect of MAP
on selected quality parameters for sweet cherries (Prunus avium L.) stored at
simulated distribution chain temperatures. ‘Lapins’ sweet cherries with maturity
grade 4-5 and 6-7 were packaged in macroperforated polyethylene “carry bags”
(control) and in trays wrapped in a laser perforated film giving passive modified
atmosphere (MAP). After packaging, the cherries were stored at 4°C for 5 days and
thereafter for 3 days at 4°C (chill) or 20°C (retail) simulating storage at chill or room
temperature in the grocery stores. Headspace gas atmosphere in the MA packages,
fruit quality, weight loss and amount of fungal fruit decay and other decays were
recorded after 1, 5 and 8 days of storage. The gas atmosphere in MA packages was
approximately 18% O2 and 4% CO2 at 4°C and between 6-9% O2 and 12-14% CO2 at
20°C. The weight loss was negligible in the MA packages at both storage conditions,
whereas the cherries in carry bags showed a weight loss from 1 to 4%. The stem
colour was significantly browner in the carry bags compared to the MA packages after
8 days of retail storage. Fungal decay was below 0.5% for both maturity grades stored
at chill conditions for 8 days. At retail conditions, 4 and 6% decay was detected for
maturity grade 4-5 in MA-packages and carry bags, respectively. For maturity grade 6-
7, the MA-packages had 9% decay and the carry bags 7%. The overall picture was that
MA packaging for sweet cherries better maintained the fruit quality than the carry
bags during the storage period of 8 days at two simulated retail conditions.
