초록

본 연구는 도계 후 원료육의 저장기간에 따른 품질 특성을 조사하여 가공업소에서 반입되는 원료육에 대하여 현행 등급판정기준인 '도계 후 2일 이내의 원료육'의 사용이 적합한지 혹은 어느 정도 연장이 가능한지 여부를 판단하기 위하여 처음으로 수행하였다. 당일 도계한 원료육부터 도계후 4일 경과된 원료육까지 총 40개의 샘플을 $3^{\circ}C$의 냉장고에 냉장보관하여 부분육으로 발골 후 가슴육에 대하여 품질 특성을 연구하였다. 도계 후 2일 경과된 원료육과 3일 경과된 원료육을 비교 분석한 결과, 신선도는 각각 6.9와 7.0, 육색은 60.22와 60.51, 총균수는 4.20과 $4.31log_{10}CFU/g$, 지방산패도는 0.056과 0.071 mg MDA/kg, 전단력은 1.43과 $1.59kg/cm^2$, 가열감량은 17.24와 15.66%의 결과를 보였다. 신선도, 육색, 총균수, 지방산패도, 전단력 및 가열감량 모두 본 연구에서 도계 후 2일 경과된 원료육과 3일 경과된 원료육간에 통계적 유의적인 차이가 없었다. 도계 후 4일 경과된 원료육은 신선도, 총균수, 전단력, 가열감량의 실험에서 2~3일 경과된 원료육과 통계적 유의적인 차이가 없었으나, 지방산패도는 0.088 mg MDA/kg으로 유의적으로 높은 값을 보였다(P<0.05). 따라서 본 실험의 결과는 도계 후 3일 이내의 원료육도 사용이 가능하다는 것을 시사하였다. 등급판정시 원료육의 사용 가능 시점을 도계 후 현행 2일에서 3일로 하루 연장할 수 있다면 닭고기 가공 및 유통업체는 원료육 사용 혹은 유통의 폭이 보다 넓어질 것으로 기대된다.

This study was first conducted to investigate the effect of post-mortem storage time of chicken meat on the quality of chicken breast, and to determine whether the current grading rule that is 'using the chicken meat within 2 day post-mortem (PM)' is appropriate or not at meat processing plants. Different methods such as freshness, lightness ($L^*$), total number of microbes, 2-thiobarbituric acid reactive substances (TBARS), shear force and cooking loss were performed. Forty samples of different PM time (0~4 day) of chicken meat were stored in the refrigerator ($3^{\circ}C$). As a result of comparing the chicken meat of 2 day and 3 day PM, torrymeter value was 6.9 and 7.0, respectively. The other values are also as follows: lightness ($L^*$) 60.22 and 60.51, total number of microbes 4.20 and $4.31log_{10}CFU/g$, TBARS value 0.056 and 0.071 mg MDA/kg, shear force 1.43 and $1.59kg/cm^2$, and cooking loss 17.24 and 15.66%, respectively. As a result, these two groups were not significantly different (P<0.05). TBARS value of the chicken meat of 4 day PM was 0.088 mg MDA/kg which is significantly higher compared to 2~3 day PM (P<0.05). Thus, the result of the study suggests that using the chicken meat within 3 day PM is also possible. If the grading rule that is 'using the chicken meat within 2 day post-mortem (PM)' is changed to 3 day PM, it will allow processing plants and distributors to more flexibly use or distribute chicken meat.
