title: Modified atmosphere packaging (MAP) and coating for improving preservation of whole and sliced Agaricus bisporus.
abstract: Freshness of mushrooms (Agaricus bisporus) was related to the internal atmosphere composition during modified atmosphere packaging (MAP) experiments using polyvinyl chloride (PVC) wrap, polyethylene-1 (PE-1) and PE-2 films. The packaged mushrooms were stored at 12 °C for 7 days and lightness value, browning index, weight loss and maturity index were also measured. The results obtained showed that the whiteness of whole mushrooms varied significantly with the type of coating (chitosan and CaCl2), but not with the type of packaging films. It was evident that the extent of darkening in whole mushroom was greater than in sliced ones after coated. In addition, mushroom in PE-2 package exhibited the lowest weight loss due to the lower permeability of film. And the type of packaging films significantly affected the maturity index of mushroom, where PE-2 packaging most effectively lowered maturity index for both whole and sliced mushrooms. By considering the overall quality, it was obvious that PE-2 packaging combined with coating treatment was the most effective to improve the preservation of mushrooms stored at 12 °C up to 7 days and satisfy consumer acceptance.
