피망에 대한 MA 저장에 적합한 포장재를 선발하기 위하여 기체에 대한 투과도가 다른 cast polypropylene (CPP), low density polyethylene (LDPE), polyolefin (MPD), polyolefin(PD961) 및 Linear low density polyethylene (LLDPE) 포장재로 피망을 포장하고 1에서 저장하면서 품질 변화를 고찰하였다. 저장 기간 중 포장 내부의 산소 농도는 4주까지 대체
Bell pepper was packed with several plastic films, and investigated the quality Characteristics such as gas composition, weight loss, microbial load, soluble solid content, ascorbic acid and color during storage at 10. Cast polypropylene (CPP), low density Polyethylene (LDPE), Polyolefin (MPD, PD961) and linear low density polyethylene (LLDPE) were used for this purpose. Oxygen concentration inside packages generally showed a 10∼14% after 1∼2 weeks, but package with CPP maintained above 15％ throughout the storage. Carbon dioxide concentration of CPP was above 2%, but other treatments showed below 2%. Weight loss of all treatments was below 3.0% after 5 weeks. Total microbial count showed a similar pattern compared to yeast and mold, and CPP maintained the highest microbial load after 3 weeks. Yellowness (b value) of bell pepper was generally increased throughout the storage, and MPD and PD961 were higher than other treatments.
