Abstract

이 연구는 한국 전통 양념을 이용한 발효 돼지고기의 품질 특성에 관한 것으로 돼지고기의 바깥 볼깃살을 채취하여 7<TEX>${\times}$</TEX>12<TEX>${\times}$</TEX>2cm 크기로 자른 후 육을 동일한 비율의 양념액에 침지하여 -1<TEX>${\pm}$</TEX>1<TEX>$^{\circ}C$</TEX>에서 20일간 숙성한 발효육[T1(마늘소스 돼지고기), T2(제육김치 돼지고기), T3(김치소스 돼지고기), T4(된장소스 돼지고기), T5(고추장소스 돼지고기)]의 품질 특성을 측정한 결과는 다음과 같다. T1은 수분이 가장 높은 반면 조단백질 함량이 가장 낮았으며, T5는 수분이 가장 낮은 반면 조단백질과 조지방 함량이 가장 높았다. 양념 페이스트와 발효육의 pH는 T1이 가장 높았으며, T3가 가당 낮게 나타났다. 보수력은 T4와 T5가 매우 높고, T3는 가장 낮았다. 전단력은 T5가 가장 높고, T4가 가장 낮게 나타났다. 지방산패도는 T3가 가장 높았으며, T4가 가장 낮았다. 휘발성염기태질소화합물은 T4가 가장 높았으며, T1이 가장 낮았다. 당도는 T5가 가장 높았으며, T3가 가장 낮았다. 염도는 T2가 가장 높았으며, T5가 가장 낮았다. 표면육색과 심부육색 모두 <TEX>$L^*$</TEX>값, <TEX>$a^*$</TEX>값, <TEX>$b^*$</TEX>값은 각각 T4, T2, T2가 가장 높았으며, <TEX>$L^*$</TEX>값은 T5가 가장 낮았다. 가열육의 관능평가 결과 전 항목 및 전체적인 기호도는 T5가 가장 높았으며, T4가 가장 낮았다. 불포화지방산 비율은 T5가 많고 T2는 적었다. 불포화지방산/포화지방산 비율은 T5, T4, T3, T1, T$, T3순이었다. 이상의 결과를 요약하여 볼 때, 소비자가 구입을 꺼려하는 뒷다리살을 한국 전통양념류를 이용하여 제품을 만들었을 때, 제품의 맛과 품질을 개선시켜 그 소비를 촉진 시킬 수 있을 것으로 사료되며 앞으로 포장방법과 유통기간 설정 등 이에 대한 더욱더 많은 연구가 이루어져야 하겠다. This study was canied out to evaluate the quality characteristics of the fermented pork with Korean traditional seasonings. The samples, outside muscle of pork ham were cut to cube(7 <TEX>${\times}$</TEX> 12 <TEX>${\times}$</TEX> 2cm) and five Korean traditional seasonings such as garlic paste(TI), pickled Kimchi(T2), pickled Kimchi juice(T3), soybean paste(T4), red pepper paste(T5) were seasoned by the proportions of meat to seasonings(1 : 1). The seasoned samples were fennented at - 1 <TEX>${\pm}$</TEX> 1<TEX>$^{\circ}C$</TEX> for 20 days. According to proximate composition analysis, all pork samples contained protein 20 <TEX>${\sim}$</TEX> 22%, fat 3 <TEX>${\sim}$</TEX> 5%, moisture 64 <TEX>${\sim}$</TEX> 70% and ash 1.8 <TEX>${\sim}$</TEX> 2.0%. However, T5 had high crude fat level and relatively low moisture content. The highest pH among treatments was shown in TI whereas T3 showed the lowest. Water holding capacity(WHC) of T4 and T5 were higher, while those values were lower in T3 compared with other treatment. Shear force value was the highest in T5, while it was the lowest in T4. TBARS value of T3 was the highest, while that was the lowest in T4. Moreover the highest VBN value was observed in T4 due to fermentation of soy protein. However, the lowest VBN value shown in Tl indicated the inhibition of protein degradation by the garlic. The highest saccarinity was shown in T5 but it was the lowest of in T3. Salinity was shown to be high in T2 and low in T5. <TEX>$L^*$</TEX> values of T4 was higher both at the surface and inner side of samples than the others but T5 showed the lowest value. T2 showed the highest <TEX>$a^*$</TEX> value but T4 and T5 showed the lowest. In the result of sensory evaluation for cooked meat, T5 had the highest score in all item including overall acceptability, while T4 had the lowest score. Unsaturated fatty acid(UFA) ratio of T5 and n were 72.16 and 69.93 respectively, and the ratio of UFA/Saturated fatty acid(SFA) were higher in the order of T5 >T4> T3 >Tl >T2. Overall quality characteristics were higher in the order of T5 >T2 >Tl >T4 >T3.
