Abstract

This study was conducted to determine the effect of L. casei KCTC 3109 on physico-chemical characteristics and TBARS values of fermented pork meat. Each pork meat were allotted to two treatments ; Control (0%), $T_1$ (supplemented with L. casei KCTC 3109 10%). The pH tenderness and water holding capacity (WHC) of $T_1$ were higher than those of control (p<0.05), cooking loss of control was higher than $T_1$. Water content, crude Int and ash were not significantly different crude protein was higher in $T_1$ compared with control (p<0.05). $L^*,\;a^*$ and $b^*$ values of control were higher than those of $T_1$ (p<0.05). TBARS values was higher in $T_1$(0.02 MA mg/1,000 g) than control (0.19 MA mg/1,000g) (P<0.05).

본 연구는 돈육 등심 부위 근육을 이용하여 유산균을 첨가하지 않은 대조구와 10% 유산균 L. casei KCTC 3109를 첨가한 처리구 $T_1$구의 비교실험을 통하여 이화학적 특성 및 항산화 효과를 측정하였다. 돈육의 일반성분에서 수분, 제방, 회분은 유의적인 차이는 없었으나 단백질 함량은 대조구가 $T_1$구보다 유의적으로 높았다. 등심 부위의 pH와 보수성은 $T_1$구가 유의적으로 높았으나(p<0.05) 가열감량은 대조구가 높은 경향을 보였다. 육색은 명도, 적색도 및 황색도에서 대조구가 $T_1$구보다 유의적으로 높게 나타났다(p<0.05). TBARS 치는 3일간 정치배양한 $T_1$구가 0.02 MA mg/1,000 g으로 대조구 0.19 MA mg/1,000 g보다 유의적으로 낮았다(p<0.05).
