큰느타리버섯의 신선도 연장을 위해 PVC wrap과 20 Polyolefin계열의 PD941 필름을 이용하여 밀봉한 후 저장온도 , 5, 1에서 저장하면서 품질변화를 조사하였다. 큰느타리버섯은 저장온도가 높을수록 호흡속도가 빠르며, 중량감소율은 저장온도 , 5, 1에서 Polyolefin계열의 PD941 밀봉포장이 PVC wrap 포장보다 중량감소가 훨씬 적었다. 포장내 가스농도중 농도는 PVC wrap포장과 Polyolefin계열의 PD941

In order to study the effect of modified atmosphere storage on extending shelf life of King Oyster mushroom was wrapped with PVC film and packed with 20polyolefin(PD941), and effects of temperature(0, 5, 10) in packaging conditions on the respiration and keeping qualities were evaluated. Higher respiratory activity and weight loss were observed at higher temperature. The concentration of Oand CO of PVC wrap and polyolefin(PD941) packages for all showed 1∼2% and 10∼14%, respectively. Polyolefin(PD941) package wan superior to the PVC wrap packaging method in Hardness, Hunter L value, Hunter b value and sensory qualities, and reducing weight loss at 0, 5 and 10 compared to PVC wrap. It was found that the optimum shelf-life period of King Oyster mushroom packaged by PVC wrap was estimated to be 50, 28 and 12 days at 0, 5 and 10, respectively, and 50, 32 and 21 days in Polyolefin(PD941).
