High purity ${\gamma}$-oryzanol was obtained from rice bran and added at 0.05%, 0.10% or 0.20% (w/w) to pork sausages. Sausages containing ${\gamma}$-oryzanol showed higher CIE $L^*\;and\;a^*$ color values than the control (p<0.05). Sausages containing ${\gamma}$-oryzanol had significantly lower hardness and chewiness in textural properties than the control (p<0.05) when determined by Instron testing machine. However, there were no differences in cohesiveness and springiness between the control and the sausages containing ${\gamma}$-oryzanol. Sausages containing >0.05% of ${\gamma}$-oryzanol had significantly lower thiobarbituric acid reactive substances (TBARS) values than the control since 12 days of storage when sausages were aerobically stored at $4^{\circ}C$ for 18 days (p<0.05). Thus, ${\gamma}$-oryzanol may have a potential application for the sausage products to inhibit lipid oxidation when used at >0.05%.

미강으로부터 추출한 ${\gamma}$-oryzanol을 소시지 제조시 0.05%, 0.10% 또는 0.20%(w/w) 수준으로 첨가하여 ${\gamma}$-oryzanol을 첨가하지 않은 대조구 소시지와 이화학적 및 관능적 특성을 비교하였다. ${\gamma}$-oryzanol을 첨가한 소시지는 색도 측정에서 대조구와 비교하여 유의적으로 높은 CIE $L^*$ 값과 $a^*$ 값을 나타냈다(p<0.05). 또한 ${\gamma}$-oryzanol을 첨가하여 제조한 소시지가 조직 특성에서 유의적으로 낮은 경도 및 씹힙성을 나타낸 반면 응집성과 탄력성에서는 유의적인 차이가 없는 것으로 나타났다(p>0.05). 항산화력을 측정하기 위하여 ${\gamma}$-oryzanol을 첨가한 소시지와 첨가하지 않은 대조구 소시지를 $4^{\circ}C$에서 18일간 저장하면서 TBARS 값을 분석한 결과 저장 초기에는 처리구와 대조구 간에 유의적인 차이가 없었으나 저장 12일째부터 ${\gamma}$-oryzanol을 >0.05% 첨가한 처리구가 첨가하지 않은 대조구와 비교하여 유의적으로 낮은 TBARS 값을 나타냈다(p<0.05). 따라서 소시지 제조시 미강으로부터 추출한 ${\gamma}$-oryzanol 첨가가 가능할 것으로 보이며 지방 산화를 억제하는데도 효과적일 것으로 보인다.
