摘要: Abstract This study investigated the effects of passive modified atmosphere packaging (MAP), storage temperature (5, 10 and 15 °C) duration 14 days on postharvest quality attributes, compositional change in flavour attributes microbiological minimally processed pomegranate arils ( Punica granatum L.), cvs ‘Acco’ ‘Herskawitz’. Volatile compounds were extracted via headspace solid phase micro-extraction (HS-SPME) analyzed by gas chromatography–mass spectrometry (GC–MS). A total 17 18 volatiles detected identified juices ‘Herskawitz’, respectively. Based physicochemical microbial evaluation, life MA-packaged ‘Herskawitz’ was limited to due fungal growth ≥2 log CFU g −1 at 5 °C. However, concentration (%) changes volatile indicated that flavour/aroma (7 days) shorter than shelf-life based appearance other (10 for both cultivars.
