Appropriate storage temperature and film material were investigated to extend storability of oak mushroom (Lentinus edodes (Berk.) Sing.) which has a high respiration rate and continued growth after harvest. Weight loss of the oak mushroom in the modified atmosphere packaging (MAP) was only 2-8%, whereas oak mushrooms that were stored without film packaging ranged 62-85% indicating that MAP was an effective method for preventing weight loss. No significant differences in weight loss were observed among the film materials used for storage. Gas compositions inside the package changed rapidly during the early stages of storage, and the kinetics of O2 and CO2 within the pouches depended upon the film material and the storage temperature. The CO2 concentration inside the film package increased to 33% in packages stored at 20℃ when polyethylene (PE) and ceramic films were used to seal the package, but only by 27% when ethylene vinyl acetate (EVA) film was used. In addition, the hardness of the mushroom continuously decreased with storage time, and ethanol production in the tissue increased as storage time and temperature increased. However, changes in the color and sugar alcohol contents showed little differences among the treatments. The results indicate that oak mushrooms should be stored using a combination of low temperature and EVA film to preserve optimum quality. KCI Citation Count: 5
