Résumé

The authors studied the effect of modified atmosphere packaging on low molecular weight carbohydrates of oyster mushrooms (Pleurotus ostreatus) during post-harvest storage at 5 and 15 °C, using highly permeable micro-perforated oriented polypropylene (OPP) film and ordinary OPP film packages. Changes in sugar and sugar alcohol contents among different treatments were measured, using high performance liquid chromatography. Trehalose content varied between pileus and stipe portions of the mushroom, in response to the gaseous environment. Increases in pileus and stipe trehalose and total sugar content were observed for mushrooms packaged in micro-perforated film packages at both storage temperatures, while they decreased in ordinary OPP film packages. Low O2 (0.4%) and high CO2 (12 to 13%) observed in these packages had more adverse effects on stipe portion trehalose and total sugar content. Only mannitol was found to be affected under low O2 and high CO2 conditions, prevailing in ordinary OPP film packages at both storage temperatures.
