Abstract

This study was carried out to investigate the influence of dietary xanthophylls supplementation on the antioxidant and color properties of broiler meat. After raised for 6 weeks, broilers were slaughtered and stored at 3$^{\circ}C$ for 9 days. Experimental treatments were divided into lutein, canthaxanthin, astaxanthin and capsanthin. The supplementation level was adjusted to 30 ppm. The pH values of the thigh was higher(P<0.05) than those of the breast. No differences in pH values were shown among xanthophylls treatments. Xanthophylls supplementation to chick inhibited the formation of TBARS(Thiobarbituric acid reactive substance) and POV(lipid peroxide) of broiler meat during storage. At 9 day storage, the TBARS and POV of xanthophylls treatment decreased as compared to the control(P<0.05). The broiler meats fed astaxanthin had antioxidant effects in both breast and thigh. Dietary xanthophyll supplementation to chick decreased the CIE L(lightness) and increased a(redness) values of broiler meats fed canthaxanthin increased(P<0.05) during storage. These results indicated that broiler meats fed xanthophylls had dark-red color and antioxidant effect during refrigerated storage.

브로일러에 xanthophylls 급여가 계육의 색깔과 항산화력에 미치는 효과를 구명하기 위하여 본 연구를 실시하였다. 30 ppm의 lutein, canthaxanthin, astasanthin, capsanthin을 생후6주 동안 브로일러에게 급여한 후 도계 처리하였다. 도계후 24시간에 가슴육과 다리육으로 발골하고 정육을 3$^{\circ}C$에 9일 동안 저장하였다. 저장기간 동안 모든 처리구의 pH는 증가하였다. 다리육의 pH는 가슴육에 비해 높은 값을 나타내었으나 처리구간의 차이는 없었다. Xanthophyll을 급여한 브로일러육은 대조구에 비해 저장기간중에 TBARS와 POV가 낮았고, 저장 9일에는 대조구와 비교하여 모든 xnathophylls 급여구에서 유의적으로 낮은 값을 나타내었다(P<0.05). Xanthophyll을 급여하면 육색의 L(명도)값이 감소하고 a(적색도)값이 증가하였다. Astaxanthin을 급여한 브로일러의 가슴육이 저장중 항산화 효과가 있었고, canthaxanthin을 급여한 브로일러의 육이 착색효과가 높았다. 이상의 결과를 종합해 볼 때 육계에 Xanthophylls를 급여하면 일반육에 비해 육색이 농후해지며 저장 중 지방산화가 억제되는 것으로 나타났다.
