Abstract

The aim of this study was to determine the chemical traits of duck meats with different rearing periods(45 70 days). The content of protein was 21.3 and 19.61% in the breast and leg at 70 days post hatched, respectively. Group at 70 days showed high protein composition than those of 45 days group. The content of fat was slightly increased with the rearing periods. The composition of Ca, mineral compound, was not showed the difference between leg and breast meat. However, it was increased with the rearing periods. The composition of Fe was not significantly different in the breast meat. However, there was a significant increase in the leg (p<0.05). It was compared 14.6 ppm at 45 days group to 27.5 ppm at 70 days group. The content of methionine was significantly increased in the breasts due to the increasing rearing periods (p<0.05), but not in leg meat. There was no significant difference between parts, but glutamic acid content was significantly decreased along with the increasing rearing periods (p<0.05). The content of collagen at 70 days(0.77 g/100 g) was higher than those of 45 days(0.65 g/100 g). It was affected by the rearing periods In the wing-removed skit, it was 0.15 g increases at 70 rearing period group. The cholesterol content was significantly increased in the leg but not in the breast. With the rearing periods, it was significantly increased in the leg (p<0.05).

본 연구는 오리 고기의 사육일령에 따른 부위별 화학적 특성을 규명하고자 실시하였다. 오리육의 단백질 함량은 70일령 가슴 및 다리육이 각각 21.13, 19.61%로 45일령 18.20, 18.69%보다 높게 나타났다. 지방은 45일령의 가슴육이 1.04%이었으나 70일령은 1.38%로 약간 증가하는 경향을 나타내었다. 무기물에서 칼슘(Ca)의 함량은 가슴 및 다리육에서 $142.1{\sim}161.1\;ppm$으로 큰 차이를 보이지 않았으나, 사육일령에 따라서 가슴 및 다리육 모두에서 사육일령이 증가할수록 약간 증가한 것으로 나타났다. 철분(F)의 함량은 가슴육에서는 사육일령에 따라 유의적인 차이가 없었으나 다리육에서 45일령이 14.6 ppm, 70일령 27.5 ppm으로 70일령에서 유의적으로 증가하는 것으로 나타났다(p<0.05). 아미노산에서 methionine은 다리육에서는 유의적인 차이가 없었으나 가슴육에서 45일령이 0.43%, 70일령 0.48%로 70일령에서 유의적으로 증가하였다(p<0.05). Glutamic acid의 함량은 부위별로는 차이가 없었으나 다리육에서 45일령이 3.06%, 70일령이 2.99%로 45일령이 유의적으로 증가한 것으로 나타났다(p<0.05). 콜라겐 함량은 45일령의 가슴살에서 0.65, 70일령 0.77 g/100 g으로 사육일령이 증가함에 따라 증가하는 경향을 나타내었다. 피부를 제거한 날개육에서는 45일령이 1.98, 70일령이 2.13 g/100 g으로 70일령이 0.15 g/100 g 이상 많았다. 콜레스테롤은 가슴육에서는 유의적인 차이가 없었으나 다리육에서 45일령이 76.77 mg/100 g, 70일령 83.75 mg/100 g으로 사육일령이 증가함에 따라 유의적으로 증가하는 경향을 나타내었다(p<0.05).
