신선 편의가공된 절단양파제품의 적정 포장방법을 개발하고자 LDPE $30{mu}m$, PD900과 PD941 필름을 이용한 수동형 MA 포장의 적용 가능성을 연구하였다. 포장필름을 달리하여 $1^{circ}C$에서 38일간 저장하면서 포장내의 가스조성, 중량 손실, 부패율, 색도, 경도 등을 측정하였다. 기체 투과도가 낮은 PD900포장이 곰팡이 부패나 육안적인 품질손상 없이 38일 동안 저장되는 데에 무리가 없었고, 색택과 가용성 고형분 함량에서도 비교적 양호하였다.
The aim of this study was to develop the appropriate packaging method for minimally processed sliced onions. The films of different gas permeabilities (LDPE $30{mu}m$, PD900 and PD941) were used for packaging 1300g of onion slices cut into octuplicate pieces. Perforated LDPE package was prepared as control for comparison. The package atmosphere and onion quality were measured through storage at $1^{circ}C$ for 38 days. PD900 package of the lowest gas permeability was the best in keeping the fresh-cut onions by maintaining MA conditions of 1-3% $O_2$ and 4-11% $CO_2$ concentrations. The benefits were reduced discoloration, decay and soakness.
