Changes of freshness in Pleurotus eryngii according to oxygen permeability of packaging film and net weight

영어: Recently, Pleurotus eryngii, King oyster mushroom is the main export item in South Korea mushroom industry. For appropriate transportation to Europe and USA markets, it is necessary to elucidate suitable conditions of storage and treatment of post-harvest during long time shipping. Whole mushrooms were packed with polypropylene anti-fog film (30 um) without trimming. The range of package weight and oxygen permeability of film were 200 g~400 g and 2000~5000 cc/m2, 24 h,atm, respectively. The weight loss ratio was increased with increasing storage time. There were no big differences in weight loss ratio according to package weight and oxygen permeability of film at low temperature storage(4oC). In case of package weight is 400 g and oxygen permeability of film is 3000 cc/m2, 24 h, atm. As a results of freshness, the optimum packing weight and oxygen permeability of film of P. eryngii were 400 g and below 2,000 cc/m2, 24 h, atm, respectively.
