느타리버섯의 호흡속도 측정 및 MA 포장 저장 실험을 수행한 결과 호흡속도는 2에서 산소소비속도 28.9∼161.4mgO/kghr로 나타났으며 이산화탄소방출 속도는 53.4∼166.9mg/kghr로 나타났다. 산소소비속도와 이산화탄소발생속도를 반응표면분석한 결과를 이용하여 느타리버섯의 저장 가능 기체조성을 예측한 결과 2.5∼4.5% 와 11.5∼l3%로 나타났다. 포장내 기체조성은 0.03mmLDPE의 경우 농도 1.6∼3.0%, 농도 3.9
This study was conducted to find out effective MA (Modified Atmosphere) gas compositions on the oyster mushroom through statistical analysis of the respiration rate and MA storage for the various packaging materials. Under the various gas compositions, the oxygen consumption rate of oyster mushroom was from 28.9 to 161.4mgO/kghr and the carbon dioxide evolution rate was from 53.4 to 166.9 mgCO/kghr at 20. The estimated MA condition of oyster mushroom were 2.5∼4.5%Oand 11.5∼l3%COby the RSREG(Response Surface Regression). The gas compositions of MA packaging are following that 0.03mm LDPE were 1.6∼3.0%Oand 3.9∼5.3%CO,0.05mm LDPE were 1.2∼1.3%Oand 9.0∼11.1%COand Nylon+PE were 0.9∼1.2%Oand 33.5∼39.6%CO. The weight loss increased at 0.03mm LDPE but has the lowest value at Nylon+PE. The hardness of pileus and stipe was decreased with storage periods. The E-value increased with storage period and seriously changed in early storage period at 12 and 20. In the 0.05mm LDPE, the gas compositions of packaging were similar to estimated gas compositions from the RSREG and the storage quality was superior to the other packaging materials in weight loss, hardness, and color difference at 4, 12 and 20 .
