Abstract

These studies were carried out to develop sausage using extracts from waste resources. The changes of pH and moisture contents were tended to be a similar to control, respectively ranged in pH 6.0~6.4 and 62~60% in moisture content. However, the water holding capacity of sausage added with chitosan and sesamol gradually were tended to be a little high, compared to control. The treatments using natural resource by-product revealed a low TBARS value, compared to control. This means that sausage added with natural by-product seem to be extend its shelf-life during storage. At the same time, the TBARS values were very similar to sausage added with 0.5% potassium sorbate. The residual nitrite contents of sausage added with natural resource by-product were tended to be a little lower than that of control. As storage time goes by, the nitrite contents of sausage product gradually were a little more decreased during storage at 3$0^{\circ}C$ than those of storage at 1$0^{\circ}C$. The lightness of sausage color gradually were a little more decreased during storage at 3$0^{\circ}C$ than those of storage at 1$0^{\circ}C$. The redness of sausage added with chitosan were a little highter, compared to control Sensory test suggested that the changes of sausage color, flavor, texture and taste were tended to be decreased gradually. In conclusion, sausage added with natural resource by-product was effective on the basis of the reduction in residual nitrite content and lipid oxidation.

천연부산물을 첨가한 소시지의 이화학적 특성을 알아보기 위하여 대조구의 pH와 수분함량을 비교한 결과 이들 성분의 변화는 유사한 경향을 나타내었다. 그런, 보수력은 대조구에 비하여 chitosan, sesamol 첨가구가 약간 높은 경향을 나타내었다. 부산물 첨가 소시지의 지방산화도는 1$0^{\circ}C$와 3$0^{\circ}C$ 저장에서 대조구에 비하여 다소 낮은 TBARS값을 나타내어 저장성이 있는 것으로 나타났다. 이러한 부산물 첨가 소시지의 지방산화도는 potassium sorbate 0.5% 첨가구와 유사한 경향을 나타내었다. 잔존아질산염 함량은 대조구에 비하여 부산물 첨가구가 약간 낮은 경향을 나타내었으며, 그중에서도 감귤껍질 첨가구가 가장 낮은 값을 나타내었다. 부산물 첨가 소시지의 명도는 대조구와 유사하였으며, 적색도는 대조구에 비하여 chitosan 첨가구가 약간 높은 것으로 나타났다. 부산물 첨가구와 대조구의 관능적인 차이는 인정되지 않았다. 따라서, 대조구에 비하여 부산물 첨가 소시지는 지방산화도와 잔존아질산염의 함량을 낮추는 특성이 있으며, 제품의 이화학적 특성은 대조구와 유사하여 육제품 제조시 첨가추출물로서의 이용가능성을 확인하였다.
