Application of modified atmosphere and active packaging for oyster mushroom (Pleurotus ostreatus)

Abstract This research investigated the effect of combining modified atmosphere packaging with bilayer active packaging (MAP + BL) on the shelf life of oyster mushroom (Pleurotus ostreatus). The BL active packaging consisted of gelatin with pomegranate peel powder (PPP) coated on the polyethylene (PE) film (gelatin + PPP/PE). Pouches of single layer (SL) of PE was used for MAP without active function (MAP + SL). Three different conditions of MAP were used i.e. high oxygen packaging (HOP), medium oxygen packaging (MOP) and low oxygen packaging (LOP). Mushroom packaged with atmospheric air (ATM) was used as control. The mushroom packed in MOP with active layer successfully increased the shelf-life of mushroom up to 11 days as compared to the control (3 days). Generally, mushroom in MAP + BL presented better results in all analyses as compared to MAP + SL. Oyster mushrooms packaged in MOP + BL showed the lowest weight loss as only 0.60 % decreased in weight was recorded throughout the storage time. Despite the lowest (p
