포장재 산소투과도 및 포장량에 따른 큰느타리버섯 신선도 변화 Changes of freshness in Pleurotus eryngii according to oxygen permeability of packaging film and net weight
pp.292-296
주요 수출버섯인 큰느타리버섯의 신선도유지에 적합한 포장량 및 포장재 산소투과도를 설정하기 위해저온 저장기간 중 품질변화를 분석한 결과, 포장량및 포장재 산소투과도에 따른 저장기간 중 중량감모율 변화는 차이없었으며, 갓신장율은 포장량 200g일경우 산소투과율이 높을수록 저장기간이 길수록 증가하였으나, 400g 처리는 산소투과도 3,000cc/m2,24h, atm일 때 가장 낮았다.포장재 내부의 O₂함량은 포장량이 적을수록 산소투과도가 낮을수록 높았으며, CO₂함량은 포장량이많을수록 높았다. 종합적으로 포장량 400g, 포장재산소투과도 2,000cc/m², 24h, atm 이하에서 판매가능한 신선도가 35일까지 유지되어 저장기간이 가장길었다.
Recently, Pleurotus eryngii, King oyster mushroom is the main export item in South Korea mushroomindustry. For appropriate transportation to Europe and USA markets, it is necessary to elucidate suitable conditionsof storage and treatment of post-harvest during long time shipping. Whole mushrooms were packed with polypropyleneanti-fog film (30um) without trimming. The range of package weight and oxygen permeability of film were200g~400g and 2000~5000cc/m², 24h,atm, respectively. The weight loss ratio was increased with increasing storagetime. There were no big differences in weight loss ratio according to package weight and oxygen permeability of filmat low temperature storage(4°C). In case of package weight is 400g and oxygen permeability of film is 3000cc/m², 24h, atm. As a results of freshness, the optimum packing weight and oxygen permeability of film of P. eryngii were400g and below 2,000cc/m², 24h, atm, respectively.
