Abstract
This study was conducted to investigate the changes of quality characteristics on seasoned pork with Korean traditional 4 types seasoning such as soybean sauce(T1); Kimchi sauce(T2); pickled shrimps sauce(T3); onion sauce(T4). The seasoned samples were aged at 10±1℃ for 13 days. The results obtained were as follows; Except for T2, pH of treatments were significantly decreased(P<0.05) as aging period increased. Salinity(%) and saccharinity(%) of seasoned meat were tended to increased during aging period. Thiobarbituric acid reactive substances(TBARS) were increased significantly during storage in all treatment(P<0.05). T4 showed the highest TBARS among the all treatment groups. Volatile basic nitrogen(VBN) values of all treatments were significantly increased(P<0.05) as storage period increased. There were no significant differences in water holding capacity(WHC) among the all treatments, and those values were not changed by the passage of storage days. Shear force values of all treatments were tended to decreased by the passage of storage days. In surface color, the values of L*, a* and b* showed a tendency of increasing value along the storage days. The values of a* and b* of T2 were significantly higher than other treatments during aging period(P<0.05). In inner color, a* and b* values of T2 were significantly higher than those of other treatments during aging period(P<0.05). In the sensory evaluation of cooked meat, T3 treatment resulted in lower score in aroma, flavor, tenderness, juiciness and overall acceptability. The number of total plate counts and Lactobacilli spp. tended to increase with storage in all treatments group. The numbers of Escherichia coli were not changed by the passage of storage time.
한국 전통 양념(T1, 간장소스; T2, 김치소스; T3, 새우젓소스; T4, 양파소스)을 이용하여 10± 1℃에서 13일 동안 숙성 중 돼지고기의 물리화학적 변화를 측정한 결과는 다음과 같다. pH는 T2 처리구를 제외한 모든 처리구에서 숙성기간 동안 유의적으로 감소하였다. 숙성기간 동안 염도와 당도는 증가하는 경향을 보였다. TBARS는 저장기간이 경과함에 따라 유의적으로 증가하였고, T4 처리구가 가장 높은 값을 나타내었다. VBN은 저장기간이 경과함에 따라 유의적으로 증가하였다(P<0.05). 보수력은 처리구 간에 차이가 없었으며, 저장기간의 경과에 따른 변화에서도 유의적인 차이가 없었다. 전단가는 모든 처리구가 저장기간이 경과함에 따라 감소하는 경향을 보였다. 표면 육색 중 L*, a*, b*값은 저장기간이 경과함에 따라 증가하는 경향을 보였으며, a*, b*값은 T2 처리구가 다른 처리구에 비하여 유의적으로 높았다(P<0.05). 심부 육색 중 a*, b*값은 T2 처리구가 다른 처리구에 비하여 유의적으로 높았다(P<0.05). 가열육에 대한 관능검사 결과, T3 처리구가 모든 검사항목에서 기호도가 가장 낮게 나타났다. 총균수와 유산균수는 모든 처리구가 저장기간이 경과함에 따라 증가하는 경향을 나타내었으며, 대장균수는 저장기간이 경과함에 따라 뚜렷한 경향이 없었다.
