Abstract

Various types of unit packaging methods were applied for 'Fuji' apples during short-term cold storage and export simulation. Gas tightness of the package was controlled stepwise in the successive two-year experiments using different perforation treatments (none, punch hole, or pinhole) and sealing methods (tie v s. heat seal). Risk of tight packaging and effectiveness of macroperforation on weight loss and quality maintenance were analyzed as related to changes in gas concentration inside the packages. Immediately after harvest, each 5 apple units were packaged in $40{\mu}m$ polypropylene (PP) film bags, stored 4 weeks at $0^{\circ}C$, and then put on the shelf for one week at ambient temperature in the preliminary experiment, In the main experiment, export process was imposed after storage simulating 2 week refrigerated container shipment at $0^{\circ}C$ plus one week local marketing at ambient temperature. Non-perforated film packaging with relatively high gas tightness induced flesh browning caused by carbon dioxide accumulation regardless of the sealing methods. Among perforated film packaging, in contrast, atmospheric modification was partly established only in the pinhole treatment and flesh browning symptom was not observed in all the treatments. Even the punch hole perforated film packaging without gas tightness effectively reduced the weight loss, whereas had slight benefits for quality maintenance. Reduced perforation using pinhole treatment seemed to improve sensory texture, while effects on physicochemical quality were insignificant. Overall results suggest the need of more minute perforation treatments on the packaging film to ensure modified atmosphere effects on quality maintenance.

'후지' 사과의 단기 저장과 모의 수출 과정에서 소포장 적용이 중량감소와 품질에 미치는 영향을 분석하기 위해 2년에 걸쳐 포장의 밀폐도를 단계적으로 조절하는 실험을 수행하였다. 포장의 밀폐도는 천공 처리 수준(무천공, 펀치 홀, 핀홀)과 밀봉 방식(끈 묶음, 열 접착)을 달리하여 조절하였다. 수확 후 사과를 $40{\mu}m$ 폴리프로필렌 필름 포장 봉지에 5개씩 담아 $0^{\circ}C$에서 4주 저장한 후, 1년차 예비실험에서는 바로 상온유통 과정을 거쳤고 2년차 본 실험에서는 2주간의 냉장 컨테이너 수출 운송과 현지 상온 유통 7일의 모의 수출 과정을 거쳤다. 천공 처리 없이 끈 묶음 혹은 열 접착한, 비교적 높은 수준의 밀폐 소포장에서는 이산화탄소 축적에 의한 내부갈변 증상이 발현되었다. 이에 비해 천공 처리 필름 소포장에서의 MA 환경조성은 핀홀 처리 소포장에서만 관찰되었고, 모든 처리에서 내부갈변 장해는 발생하지 않았다. 밀폐도가 낮은 펀치 홀 천공 처리 필름 소포장에서도 단기 저장 후 모의 수출 과정에서 중량 감소를 줄이는 효과가 나타났으나 과일의 이화학 품질에 미치는 영향은 미미하였다. 천공도를 낮춘 핀홀 처리 역시 이화학 품질 유지 효과는 없었으나 조직감 관능 유지에 효과가 있는 것으로 나타났다. 따라서 사과의 단기저장과 수출과정에 소포장 기술을 적용할 때 MA 조성을 통한 품질유지 효과를 높이기 위해서는 펀치 홀 천공보다는 훨씬 미세한 천공 처리의 필요성이 제시되었다.
