This study was carried out to investigate proper modified atmosphere condition of king oyster mushroom (Pleurotus eryngii) during cold storage and distribution. King oyster mushrooms were divided into two treatments: 1 μ L/L 1-methylcyclopropene for 20 hours at 0℃ (1-MCP), while the other treatment was left at 0℃ (control). They were packaged with 30㎛ oriented polypropylene (OPP, 1238.0 cc/m2·day·atm O2), and microperforated (MP3, 3179.9cc/m2·day·atm O2) film. Quality and sensory evaluation parameters of weight loss, stem firmness, skin color, off-flavor, overall quality were monitored after 3, and 4 weeks storage at 0℃ and plus 3 days on the shelf at room temperature. 1-MCP treated mushroom packaged with MP3 film kept 3.6~10.9% O2 and 9.0~13.3% CO2 concentration in the bag during storage, and showed high overall quality at 4 weeks storage at 0℃ + 3 days on the shelf at room temperature because of the lowest development of off-flavor, stem discoloration, and cap softening among the treatments.
