본 연구는 포장방법에 따른 사슴고기의 냉장저장 중 이화화적 성질의 변화에 대해 알아 보기 위하여 실시하였다. 생체중 220 $kg{pm}10$ kg내외의 Elk 암컷 5마리를 도축하여 24시간 냉각한 후 발골하였고, 배최장근과 대퇴 근을 채취 하여 냉장온도로 25일간 유지하면서 비교 분석하였다. 보수성은 저장기간이 경과함에 따라 감소하는 경향이었고, 진공포장저장구가 보수성이 가장 낮았다. 저장기간이 경과함에 따라 TBARS가는 증가하였고, 진공포장저장구가 가장 낮은 TBARS가를 나타내었다. 저장기간이 경과함에 따라 VBN가는 증가하였고, 진공포장저 장구가 가장 낮은 VBN가를 나타내었다. pH는 저장기간이 경과함에 따라 증가하였고, 진공포장한 처리구가 가장 낮았다. 저장기간이 경과함에 따라 함기포장 처리구는 증가하였으나, 진공 포장처리구와 가스치환 포장처리구는 연도가 감소하였다. 대퇴근의 밝기는 포장방법에 따른 차이가 나타나지 않았고, 배최장근은 진공포장 처리구가 함기포장 처리구와 가스치환 포장처리구보다 유의적으로 밝았다. 대체적으로 진공포장 처리구가 함기포장 처리구와 가스치환 처리구보다 적색도가 높게 나타났다. 황색도는 저장기간 경과에 따라 증가 후 감소하는 경향을 나타내었고, 진공포장 처리구가 대체적으로 황색도 높았다.
A total of 5 female elk deer (220 $kg{pm}10$ kg) were included in a study on the changes in physico-chemical properties of deer meat during storage at $4^{circ}C$. The deers were exposed to normal pre-slaughter handling and put under anesthesia before slaughtered. The loin and leg cuts were deboned from the carcass after 24hrs slaughter. The samples weighing approximately 300 g were packaged using three packaging methods : Atmospheric packaging(A), Vacuum packaging (V) and Modified atmospheric at packaging (M: 80% $CO_2$ +20% $N_2$)and stored for 3, 7, 11, 15, 20 and 25days at $4^{circ}$. The ability of moisture maintenance tended to be decreased with the passage of storage time, and that of the meats treated with the vacuum wrapping was lower than that with other wrapping methods. TBARS values of the meats with the regardless of treatments was increased with the passage of storage time, although the values with vacuum wrapping was lowest. VBN values of the meats with the regardless of treatments was also increased with the passage of storage time, although the values with vacuum wrapping was also lowest. The pH values of the meats with the regardless of treatments was also increased with the passage of storage time, although the values with vacuum wrapping was also lowest. For the meat softness, the value of the meats treated with atmospheric packaging was increased with the passage of storage time, but the values with vacuum wrapping and modified atmospheric packaging were respectively decreased. There were no significant differences in luminosity of leg, although loin treated with vacuum wrapping was significantly brighter than that with atmospheric packaging and modified atmospheric packaging. In general, the index of red color of the meats treated with vacuum wrapping was higher than that with atmospheric packaging and modified atmospheric packaging. The index of yellow color tended to be decreased after increment for a time with the passage of storage time, although the value with vacuum wrapping was generally higher than that with other wrapping methods.
