Storage Quality of Minimally Processed Onions as Affected by Seal-Packaging Methods

포장방법에 따른 신선 편의가공 양파의 저장품질 변화

  • Published : 2003.12.01

Abstract

The effects of packaging methods on the storage quality of minimally processed (prepeeled) onions were investigated to determine the optimal packing design. Various packaging treatments used for modifying headspace atmospheres included two passive MAP using LDPE and PP films, two active MAP using a gas mixture of 20% $O_2/10%\;CO_2/balance\;N_2$ and an ethylene scavenging sachet, and moderate vacuum packaging (MVP). The quality attributes of onion samples were evaluated periodically in terms of flesh weight loss, color of cut surface, decay ratio, microbial counts, and sensory properties during storage at $10^{\circ}C$ for 28 days. Packaging methods did not significantly influence surface color, weight loss, and microbiological populations of mesophiles, psychrotrophs, and lactic acid bacteria. They did, however, affect sensory characteristics as well as decay occurrence. Results indicated that seal-packaging with a gas-permeable plastic film under a mild vacuum condition could retain better onion quality in terms of microbial decay and visual sensory aspects as compared with the other packages.

신선 편의가공 양파제품의 적정 포장방법을 탐색하고자 polyolefin계 유연 필름(LDPE, PP)을 이용한 수동 MAP, 20% $O_2/10%\;CO_2/70%\;N_2$ 혼합기체 또는 에틸렌 흡수제를 첨가한 능동 MAP, LDPE 필름으로 감압 포장한 MVP 등의 적용 가능성을 조사하였다. 박피 양파의 포장방법을 달리하여 $10^{\circ}C$에서 28일간 저장하면서 이화학적, 미생물, 관능적 품질변화를 측정하여 개별 품질인자에 대한 포장처리 효과를 검토하였다. 전체적으로 포장방법에 따른 저장중 박피 양파의 표면색, 중량 감소, 미생물 증식은 차이를 분명하게 구분하기 어려웠으나, 외관품질과 부패율 측면에서는 일정한 차이를 식별할 수 있었다. 결과적으로 기체투과성 LDPE 필름에 일정수준의 진공을 적용하여 밀봉 포장한 MVP가 다른 포장구에 비해 상대적으로 박피 양파의 저장품질을 우수하게 유지하는 것으로 확인되었다.
