This study was conducted to investigate the antioxidant activity of paprika in the lard-pork model system adding ground fresh paprika (3%) and paprika powders (5%). Paprika powders were obtained through 4 drying methods (freeze, vacuum, far infrared-ray, and hot-air). In the lard and meat-fat mixture (containing lard 30%) containing paprika powders, the rate of increase in the peroxide value (POV) and thiobarbituric acid (TBA) value decreased notably during the refrigerated storage ($4^{\circ}C$) compared to the control without paprika. Therefore, paprika powders showed potent antioxidant activity and especially the freeze dried paprika powder revealed the most effective activity among them. However, its antioxidant activity was still lower than that of the fresh paprika because the addition of fresh paprika in the lard and meat-fat mixture merely increased the POV and TBA value. In linoleic acid oxidation, the addition of capsanthin 500 ppm to mixed linoleic acid and 10 ppm of $FeCl_3$ (LF) inhibited the formation of peroxides by 15.2% compared to LF, showing its iron scavenging ability. When mixed antioxidants (${\beta}$-carotene 200 ppm + ascorbic acid 100 ppm, capsanthin 200 ppm + ascorbic acid 100 ppm) were added in LF, synergistic effects were obtained with 57.7 and 60.4% of inhibition of peroxide formation, respectively.

항산화성의 카로티노이드계 물질의 우수 급원인 파프리카를 돈지 모형계에 사용하여 항산화효과를 보고자 하였다. 돈지에 원적외선 $50^{\circ}C$에서 건조한 파프리카 분말(PP) 3, $5\%$와 fresh paprika(FP)를 $3\%$ 첨가하여 $4^{\circ}C$에서 8일 동안 지질 산화 억제 효과를 비교하였다. PP와 FP 첨가군의 POV와 TBA값 증가율은 대조군에 비해 현저히 낮았으며, 특히 FP $3\%$ 첨가군은 냉장저장 8일째에도 거의 변화가 없었고, 불포화지방산 파괴는 가장 작게 나타나 가장 우수한 지방산화억제효과를 보였다. 그러므로 돈지 모형계에서 파프리카의 지질산화 억제효과는 원적외선건조로 인한 항산화성분의 파괴로 감소하며, 항산화성분이 다량 함유된 FP는 육제품 지방산화에 대해 우수한 산화방지제로 사용될 수 있음을 확인하였다
