Effect of Monascus Koji on the Quality Characteristics of Bologna-Type Sausage

홍국 첨가가 소시지 품질특성에 미치는 영향

  • Published : 2003.04.01

Abstract

Effects of Monascus koji on color, peroxide value, textural properties, microbial stability, and sensory characteristics of bologna-type sausage during storage at $4^{\circ}C$ for 22 days were studied. Addition of 2% Monascus koji resulted in attractive color and distinctly improved color retention. Lipid oxidation was effectively inhibited by lowering the level of peroxide value. Textural properties and microbial stability of the samples were not affected, whereas color was improved by the addition of Monascus koji. Utilization of Monascus koji in meat product could reduce the use of nitrite and inhibit lipid peroxidation during storage.

홍국의 아질산염 저감화 소재로서 활용 가능성을 검토하기 위하여 bologna-type 소시지에 Monascus ruber IFO 32318로 제조한 홍국을 2% 첨가하고 $4^{\circ}C$에서 22일간 저장하면서 1, 7, 14, 22일에 시료를 채취하여 품질 특성을 조사하였다. 홍국의 첨가는 전 저장기간에 걸쳐 소시지의 색상유지에 크게 기여하였으며, 특히 소시지의 단면보다 표면 색상의 개선에 큰 효과를 나타내었다. 대조군에 홍국을 첨가한 경우 대조군에 비해 지질 과산화물 생성이 유의적으로 억제된 반면 대조군에서 아질산염과 비타민 C를 제외하고 홍국을 첨가한군은 대조군보다 과산화물의 생성이 유의적으로 많아 홍국이 비타민 C와 아질산염의 효과를 완전히 대체하지는 못하였다. 기계적 texture는 대조군에 홍국를 첨가한 군이 저장초기에 탄력성, 껌성, 경도 및 응집성에서 높은 값을 나타내었으나 저장 14일 이후에는 모든 군에서 차이가 나타나지 않아 장기간 저장하는 경우 홍국의 첨가가 소시지 texture에 영향을 미치지 않는 것으로 나타났다. 홍국첨가에 의한 미생물 증식 억제효과는 뚜렷이 나타나지 않았다. 관능적으로도 홍국을 첨가한 경우 소시지 외관의 색상을 개선시켰으며 유의적이지는 않으나 산패취 도한 저하되는 경향을 나타내었고, 조직감 및 맛과 전반적인 기호도에서 대조군과 유의적인 차이를 나타내지 않아 홍국을 육가공품 제조에 적절히 활용하므로써 아질산염을 부분적으로나마 대체할 수 있는 소재로 활용가능할 것으로 기대된다.
