Abstract

The seasoned pork loin manufactured using with seasoning sauce that were prepared with 3 different composites of medicinal plant extracts ($T-1{\sim}3$). The the quality characteristics were investigated during storage at $4^{\circ}C$ for 15 days. Sensory evaluation was higher in medicinal plant extracts added seasoning pork, in particular, significantly highest in group T-1. Lightness ($L^*$) value tended to decrease with increasing storage days, redness ($a^*$) was significantly higher in the medicinal plant composites added groups (T-1, 2 and 3) than control, yellowness ($b^*$) had no significant difference among three groups added medicinal paint composites. In hardness test, raw pork (control) was lower than seasoned pork groups, but tended to increase by added medicinal plant composites. Cooking loss increased with increasing storage period, but there was no significant difference between the seasoned pork groups ($T-0{\sim}3$). The changes of pH showed lower in control than seasoned pork groups ($T-0{\sim}3$) added seasoning sauce. Moisture content decreased with increasing storage period. VBN content increased during storage. After storage for 15 days, it was significantly higher in the order of T-3 >> T-0 > T-2 > T-1.

양념돈육의 저장성 및 기능성을 향상을 위해 돈육 양념소스에 항산화성이 우수한 한약재 조성물을 첨가하여 15일간 냉장저장($4^{\circ}C$)하면서 양념돈육의 물리 화학적 특성을 측정하였으며 한약재 조성물은 산조인, 산수유, 단삼, 꿀풀, 선복화, 뽕잎, 곽향(T-1), 산조인, 산수유, 단삼, 꿀풀, 선복화, 뽕잎, 오가피(T-2), 산조인, 산수유, 단삼, 꿀풀, 선복화, 곽향, 오가피(T-3)등 3종류의 조성물을 양념소스에 1%씩 첨가하였다. 관능평가 결과 전반적인 기호도면에서 한약재를 첨가한 실험군이 다소 점수가 높았으며, 전반적인 기호도에서 한약재 조성물(T-1)이 유의적으로 높게 평가되었다. 육색의 변화는 양념육에서 명도는 저장기간이 길어질수록 감소되었으며, 적색도는 한약재 조성물 첨가군(T-1, 2 및 3)이 무첨가군(T-0)에 비해 유의적으로 높게 나타났다. 황색도는 저장 초기 원료육에 비해 양념육에서 약 2배 정도 높게 나타났으나, 한약재 조성물 첨가군에서 유의성은 적었다. 조직감 측정에서 양념육(T-1)은 경도 및 탄력성이 원료육에 비해 경도가 낮았으나, 한약재 조성물의 첨가시에 다소 상승하였다. 가열감량은 저장 기간이 길어짐에 따라 다소 높았으며, 양념육에서는 저장 기간에 따른 유의적인 차이가 적었다. 저장기간에 따른 pH의 변화는 양념을 첨가한 경우 대조구보다 다소 낮았다. 수분함량은 저장기간이 경과할수록 감소되었으며, 실험군간의 큰 유의차는 없었다. VBN 함량은 저장기간에 따라 점차 상승하여 저장 15일 이후에는 T-3 > T-0 > T-2 > T-1의 순으로 유의적인 차이를 나타내었다.
