Abstract

This study was investigated the effect of aging at low temperature of seasoned pork with Korean traditional sauces. The samples, pork loins were cut by the shape of cube ($5{\times}15{\times}5\;cm$) and porks were seasoned with Korean tradition sauce such as soy sauce base (T1), red pepper sauce base (T2), and soybean sauce base (T3) in the same proportion of meat seasonings, respectively. The seasoned samples were stored, at $1{\pm}1^{\circ}C$ during 28 days. Surface meat color of seasoned pork was affected by the kind of sauces. Lightness of seasoned pork with soy sauce was decreased with increased in periods while red pepper sauce made it more red and soybean sauce produced a light seasoned pork, Lightness of inner meat color of seasoned pork was decreased with increased aging periods, and seasoned pork with soy sauce was lower compared to other treatments. TBARS of seasoned pork with soy sauce was lower compared to other treatments, and increased TBARS in all treatments with aging period. Total plate counts were increased with aging period, and those of seasoned pork with soy sauce were lower compared to other treatments. The microbial counts of Escherichia coli levels in all treatments was higher at the first day of aging periods. However Escherichia coli levels were decreased with increasing the aging period. Lactobacilli spp. of seasoned pork with soy sauce was not increased during aging periods, whereas other treatments were increased with aging period increased.

한국 전통 장류를 이용한 양념 돈육의 저장 안정성에 관한 연구로 돼지고기의 등심을 채취하여 $5{\times}15{\times}5\;cm$ 크기로 자른 후 육을 동일한 비율의 양념액에 침지하여 $1{\pm}1^{\circ}C$에서 28일간 숙성하면서 양념육(간장소스 양념육, T1; 고추장소스 양념육, T2; 된장소스 양념육, T3)의 품질 특성을 조사하였다. 양념육의 표면 육색은 소스의 영향을 많이 받았으며 간장 소스로 양념한 돈육의 명도는 낮게, 고추장소스로 양념한 돈육의 적색도는 높게, 된장 소스로 양념한 돈육의 명도는 높게 나타났다. 심부 육색의 명도는 모든 처리구에서 숙성기간에 따라 감소하였으며, 간장 소스로 양념한 돈육에서는 낮게 나타났다. TBARS는 간장 소스로 양념한 돈육이 다른 처리구에 비해 낮게 나타났으며 전 숙성기간 동안 증가하였다. 총균수는 모든 처리구에서 숙성기간에 따라 증가하였으며 간장 소스로 양념한 처리구가 다른 처리구에 비해 전 숙성기간 동안 낮은 총균수를 나타내었다. 대장균 수는 숙성 초기 $2.7{\sim}3.27\;log_{10}CFU/g$으로 다소 높게 나타났으나 숙성기간의 증가에 따라 처리구들에서 감소하였으며, 고추장 소스로 양념한 처리구는 숙성 14일에 된장소스로 양념한 처리구는 숙성 28일에 대장균이 나타나지 않았다. 유산균 수는 간장 소스로 양념한 처리구에서 숙성기간 동안 유산균수의 증가가 나타나지 않았으며, 고추장 소스로 양념한 처리구와 된장 소스로 양념한 처리구에서는 숙성기간에 따라 증가하였다.
