가열온도를 $58^{\circ}C\;및\;65^{\circ}C$로 하고 가각 가열시간을 달리하여 제조한 돈육소시지의 몇가지 특성을 검토하였다. 소시지의 표면색도는 $58^{\circ}C$로 가열하였을 때에 l(명도), a(적색도) 및 b(황색도)값이 각각 64.60~65.26, 9.14~9.94 및 8.68~9.34이었고 $65^{\circ}C$ 가열의 경우는 각각 65.16~66.68, 8.78~9.62 및 7.66~8.36이었다. 그리고 gel강도는 $58^{\circ}C$에서 120분 이상 가열, $65^{\circ}C$에서 40분 간의 가열이 높앗으며, $NO_2$의 잔존량은 $58^{\circ}C가\;65^{\circ}C$의 가열 보다 더 높았고 가열시간이 길어지면서 감소하는 경향이었다. 총균수는 $58^{\circ}C$의 가열이 더 많았으며 전제적으로 $8.7{\times}10^{2}~3.5{\times}10^{3}$이었다. 유리아미노산 함량은 $58^{\circ}C와\;65^{\circ}C$ 가열 사이에 현저한 차이는 없었고 Asp, Glu 및 Lys가 많이, Cys, Met 및 Tyr 등이 적게 함유되어 있었다. 관능검사 결과 역시 가열온도와 시간에 따른 차이가 없었다.
This study was carried out to investigate several kinds of characteristics of pork sausage prepared by different cooking temperature and time (60, 90, 120, 150, 180 minutes in $58^{\circ}C$ and 25, 40, 55, 70, 85 minutes in $65^{\circ}C$). In case of color, L(bright), a (red) and b(yellow) value were 64.60-65.26, 9.14-9.94 and 8.68-9.34 in $58^{\circ}C$, and 65.16-66.68, 8.78-9.62 and 7.66-8.36 in $63^{\circ}C$, respectively. Gel strength showed high when cooking time was 120, 250 and 180 minute in $58^{\circ}C$ and 40 minute in $65^{\circ}C$. Residual nitrite concentration showed higher $58^{\circ}C$ than $65^{\circ}C$ and decreased gradually as cooking time elevated in all cooking temperature. Total plate count in 58$^{\circ}C$ was higher than $65^{\circ}C$, was wholly $8.7{\times}10^2~3.5{\times}10^3$.In case of free amino acid content, Asp, Glu and Lys were high and Cys, Met and Tyr low and was not different with $58^{\circ}C$ and $65^{\circ}C$. The result of sensory evaluation was not different (p<0.05) with $58^{\circ}C\;and\;65^{\circ}C$.
