팽이버섯의 선도유지를 위한 적정 포장방법을 구명하기 위하여 팽이버섯의 호흡특성과 필름두께에 따른 기체조성을 사전 조사한 다음 현행 포장방법인 일반필름포장(PM)과 진공포장(VM), 그리고 25%와 50%, 10%와 20%를 각각 혼합하여 충전한 가스포장(AM)을 에서 12일 동안 저장하면서 선도유지특성을 비교하였다. 팽이버섯의 호흡 속도는 에서 , , 에서 , 에서 로 조사되었으며, 기체투과율이 좋은 LDPE 필름을 사용할 경우 40
To develop an Enoki mushroom packaging method, mushrooms were stored at for 12 days after passive MAP packaging(PM), vacuum packaging(VM), and gas flushing packaging(AM), after investigation of film thickness influences on respiration rates and gas compositions(LDPE films 20, 40, and 60 m in thickness were tested). Enoki mushrooms had respiration rates of 26.4 mL at , 80.0 mL at , 130.9 mL at , and 130.9 mL at . A film thickness of 20 m was chosen for further tests to maintain the oxygen concentration above the minimum growth level; the thinnest film offered a higher gas transmittance rate than did the thicker films. No anaerobic respiration was evident over 12 days of storage using any packaging method, with the exception of VM. AM, using a high concentration of , restricted respiration rate. Mushrooms packaged using the VM method showed the greatest weight loss and extent of discoloration among the packaging methods tested, followed by AM mushrooms using 50% . Mushrooms packaged by the VM and PM methods developed a serious off-flavor after 2 days of storage, and a high stipe elongation rate after 5 days of storage, respectively. However, AM using 50% of various gas ratios tested, allowed Enoki mushrooms to be maintained for up to 12 days without development of off-flavor, discoloration, or moldiness.
