초록

본 연구에서는 진공포장재의 산소투과도와 저장온도에 따른 햄버그스테이크의 저장성과 품질변화를 조사해 보고자, PA/PE필름에 진공포장 후 냉장 저장($5^{\circ}C$)한 대조구(C)와 EVOH/PE 공중합필름에 진공포장후 냉장 저장($5^{\circ}C$)한 T1구, 그리고 PA/PE필름에 진공포장 후 냉동 저장($-18^{\circ}C$)한 T2 구로 나누어 처리하였다. T1구는 저장기간이 경과함에 따라 총균수와 Brochothrix thermosphacta균의 성장이 C구와 유사하게 이루어졌다. 그러나, Pseudomonas균은 T1구가 C구에서보다 유의적으로 낮은 균수를 보였다. VBN값은 C구에서 가장 빨리 증가하였고, 그 다음으로 T1과 T2의 순이었다. TBARS값은 T2구에서 다른 구에 비하여 저장 4일째부터 낮았고, T1 시료는 T2 시료보다 저장 14일째 낮게 나타났다. 처리구간 기계적 색도 값은 저장기간 중 일관된 변화 및 시료간 차이를 나타내지 않았다. 기계적 경도 값은 저장기간 중 지속적으로 증가하는 경향을 보였다. T1구 시료는 C구에 비하여 풍미와 이취항목에서 2일 정도 품질이 더 우수하게 유지되는 것으로 평가되었으며, 냉동시료의 경우에는 해동 후 조직감이 12일 후 상품성 기준인 5.0 미만으로 평가 되었다. 전체적 선호도는 저장 6일까지는 C 시료, 8일부터 12일까지는 T1 시료, 그리고 14일에는 T2 시료가 가장 높았다. 결론적으로, EVOH/PE 공중합필름과 같은 산소고차단성 포장재를 냉장 햄버그스테이크에 사용할 경우 풍미나 이취 등 관점에서 저장수명을 증대시키는 효과가 나타났으나, 14일 이상 장기간 저장이 요구될 경우에는 $-18^{\circ}C$에서의 냉동 보관이 추천된다.

This study investigated the effects of the oxygen permeability of vacuum packaging film and the storage temperature on the quality and shelf life of Hamburg steaks during storage for 14 days. Control samples (C) were packaged in a polyamide/polyethylene (PA/PE) film and stored at $5^{\circ}C$. Treatment samples were either packaged in an ethylene vinyl alcohol/polyethylene (EVOH/PE) copolymer film and stored at $5^{\circ}C$ (T1), and in a PA/PE film and stored at $-18^{\circ}C$ (T2). The initial total plate count (TPC) was 3.6 log cfu/g. In T1 samples, TPC and Brochothrix thermosphacta counts were increased, similar to those in C samples, whereas Pseudomonas spp. counts were significantly lower than those in C samples during storage. Over the storage period, the volatile basic nitrogen values increased most rapidly in C samples, followed by T1 and then T2 samples. The values of thiobarbituric acid reactive substances steadily increased in all samples during storage. The colour parameters were not significantly different among the samples during storage. T1 samples maintained sensory qualities in flavour and off-odour parameters for two days longer than C samples did. At day 12, T2 samples were evaluated as being below the marketability score of 5.0 for texture. In conclusion, using high oxygen barrier films like EVOH/PE copolymer for packaging Hamburg steaks could extend the sensory qualities in view of flavour and off-odour during chilled storage. However, frozen storage at $-18^{\circ}C$ is recommended when the storage period is extended beyond 14 days at $5^{\circ}C$.
