본 실험은 홍삼추출물의 농도별 처리를 통한 저염, 저지방 소시지 개발을 위하여 무처리(C), 아스코르빈산 나트륨 0.1%(V), 홍삼추출물(RGE) 0.5%(T1), 1%(T2) 및 1.5% (T3)를 첨가하여 품질 평가를 실시하였다. pH, 가열감량, CIE $b^*$은 T3처리구가 다른 시험구보다 높게 나타났으며(p<0.001). 명도(CIE $L^*$) 및 적색도(CIE $a^*$)는 낮게 낮아졌다(p<0.001). 또한, T3이 C보다 경도(hardness) 및 표면경도(surface hardness)가 낮게 나타났으나(p<0.01), 응집성(cohesiveness)은 RGE처리구가 높게 나타났다(p<0.05). 관능검사 측정결과 향기에서 T2 및 T3이 C 및 V보다 높게 나타내었지만(p<0.05), 육색, 맛, 조직감, 다즙성 및 종합적인 기호도는 시험구간 유의적인 차이를 나타내지 않았으며, 저장 1, 2 및 3주차의 TBARS에 있어 T3가 다른시험구보다 유의적으로 높게 나타났으나(p<0.01), T2 및 T3는 저장기간 동안 TBARS의 유의적인 변화가 나타내지 않았다(p>0.05). VBN 및 총균수는 저장 3 및 4주차에는 RGE처리구가 C보다 유의적으로 낮게 나타났다(p<0.01). 이상의 결과, 1% 이상의 RGE첨가구가 지방산화, 향기, 미생물학적 측면에서 우수한 결과를 나타내었다.
In this study, the effects of red ginseng extracts (RGE), which has been used as an antioxidant and antimicrobial agent, on pork sausage were evaluated. The treatments were as follows; addition of 0.01% sodium ascorbate (V), 0.5% RGE (T1), 1.0% RGE (T2) and 1.5% RGE (T3) to the basal formula (C). T3 had a significantly higher pH, cooking loss and yellowness ($CIEb^*$) and lower lightness (CIE $L^*$) and redness (CIE $a^*$) than the other samples. The hardness and surface hardness values of 1.5% RGE treated sample were significantly lower (p<0.01) than those of C. However, the cohesiveness values of the RGE samples were higher than the others (p<0.05). In the sensory evaluation, no significant differences in color, taste, texture, juiciness and acceptability were observed among the tested samples, while, the aroma scores of T2 and T3 were higher than those of the C and V samples (p<0.05). The TBARS values of RGE treated groups were higher (p<0.05) than the C sample after 1, 2 and 3 weeks of storage; however, this value did not increase with storage time (p>0.05). When the RGE concentration was high, the reduction in total plate counts and VBN value at week 3 and 4 of storage (p<0.01) decreased. In conclusion, red ginseng extracts seemed to have a positive impact on lipid oxidation, aroma and the microbial characteristics of pork sausage.
