Abstract

The present study was designed to study the antioxidant activity and physicochemical and microbiological characteristics of Pork Kalbi sauce added with Smilax china L. extract(0%, 0.25%, 0.5% and 0.75%) for 5 weeks. Total microbial counts were slightly higher in control and 0.25%-added group, therefore, more addition of Smilax china L. extract lowered total microbial counts. Alpha-diphenyl-β-picrylhydrazyl(DPPH) radical scavenging activity was significantly higher in 0.75%-added group compared to those in others(p<0.05). Also, thiobarbituric acid reactive substances(TBARS) was significantly lower in 0.5% and 0.75%-added groups compared to others(p<0.05). These results indicated that Smilax china L. extract addition increased the antioxidant activity of Pork Kalbi sauce and could improve the shelf-life during storage.

본 연구는 토복령 추출물의 항산화 활성 및 저장성 증진 가능성을 보고자 돼지 갈비소스의 5주간의 품질변화를 조사하였다. 저장 4주째에 총 균수는 대조군과 0.25% 첨가군에서 0.5%와 0.75% 첨가군에 비해 높은 수치를 나타내어, 토복령 추출물 첨가량이 많아질수록 총 균수는 낮아짐을 알 수 있었다. DPPH 라디컬 소거 활성은 첨가량이 많아질수록 증가하였으며, 토복령 추출물 0.75% 첨가군은 유의적으로 높은 소거 활성을 나타내었다(p<0.05). 또한, 토복령 추출물 첨가량이 증가할수록 TBARS는 낮아졌으며, 0.5%와 0.75% 첨가군은 유의적으로 낮은 수치를 보였다(p<0.05). 본 실험 결과로 토복령 추출물의 항산화 활성을 통한 기능성 향상과 항균 효과에 의한 저장성 강화로 식품 첨가 보존제로서의 개발 가능성이 있을 것으로 사료된다.
