Abstract

The experiment was conducted to study the effect of sea urchin shell powder (SUSD) on the sensory evaluation, meat color, fatty acid and amino acid contents of chicken meat. One hundred sixty broilers were fed diets for five weeks containing 0, 1, 3 and $5\%$ of sea urchin shell powder. The shear forces of the treatment groups were higher than the control uoup and the water holding capacity (WHC) was higher in the control group (P<0.05). The heating loss and pH were not significantly different between control and treatment groups (P<0.05). The hardness, juiciness and flavor evaluated by sensory evaluation were improved by treatments, especially in T2 (P<0.05). The meat color of the treatments group showed redder and darker than that of the control group owing to lower L$\ast$ and higher a$\ast$ value. Among fatty acids, oleic acid contents of the treatment groups were higher than that of the control group. The treatment groups showed a significantly higher total amino acid content (P<0.05) compared to the control group. The results of this experiment indicated that dietary SUSP tended to improve the sensory evaluation.

본 연구는 성게 껍질 분말을 사료내 첨가하여 그 첨가 수준(0, 1, 3, $5\%$)에 따라 계육의 관능검사, 육색, 지방산 및 아미노산 조성 등의 이화학적 특성을 검토하고자 broiler 160수를 공시하여 실시하였다. 전단력은 대조구보다 처리구에서 높고, 보수성은 대조구에서 높았으며(P<0.05), 가열감량, pH는 유의성이 인정되지 않았다. 관능검사 결과 성게 껍질 분말 급여구에서 연도, 다즙성, 풍미가 높은 점수를 나타내었는데 특히 T2에서 유의적인 (P<0.05) 차이를 나타내었다. 육색은 처리구에서 대조구보다 비교적 L$\ast$ 값이 낮고, a$\ast$ 값이 높아 육색이 어두운 편이었다. 대조구에 비해 처리구에서 oleic acid 함량이 유의하게 높거나 높은 경향을 나타내었으며, 총아미노산 함량은 대조구보다 처리구에 많은 함량을 나타내었다. 본 실험 결과 육계사료 내에 성게 껍질 분말의 급여는 관능검사의 결과를 개선할 것으로 사료된다.
