Résumé

The effects of different types of semi-permeable films and antioxidant solutions on the quality of minimally processed pomegranate arils was evaluated during storage at 4 plus or minus 0.5 °C for 14 days. Colour changes were not observed and the browning was slight in all the treatments studied but highest on those without antioxidants. pH and acidity values remained constant and the soluble solids content increased only in the arils packaged in perforated polyethylene films due to the high dehydration. The CO2 concentration inside the BB4 films reached 22%. The aerobics mesophiles count and moulds and yeast count were low in all the treatments and in the semi-permeable films a reduction was observed. The uses of semi-permeable films in minimally processed pomegranate arils allowed storage for 14 days, at 4 plus or minus 0.5 °C, with good chemical, physical and microbiological quality.
