전남산(全南産) 오리고기의 아미노산(酸)을 gas chromatography에 의하여 분석(分析)하여 다음과 같은 결과(結果)를 얻었다. 1. 오리고기의 일반성분(一般成分)은 조단백질(粗蛋白質) $13.61%{\sim}21.19%$, 조지방(粗脂肪) $17.32%{\sim}34.92%$, 회분(灰分) $0.56%{\sim}1.09%$, 수분(水分) $50.91%{\sim}65.72%$로 되어 있다. 2. 오리고기 단백질의 아미노산(酸)은 alanine 6.10%, valine 2.75%, glycine 7.13%, iso-leucine 2.20%, leucine 4.54%, proline 4.90%, threonine 5.80%, methionine 1.15%, hydroxy proline 3.20%, phenylalanine 3.01%, aspartic acid 6.70%, glutamic acid 12.71%, lysine 4.95%, arginine 1.11%, histidine 5.60%, cystine+cysteine 4.40%이며, serine과 tyrosine은 trace로 함유되어 있다. 3. tryptophane을 제외하고 전(全) 필수아미노산(酸)을 정량(定量)하였다.

Amino acids of duck-meat in Jeon-nam have been analyzed by gas chromatography. Through this analysis, the following results were obtained. 1. The quantities of general components in duck-meat were determined $13.61%{\sim}21.19%$ protein, $17.32%{\sim}34.92%$ fat, $0.56%{\sim}1.09%$ ash, and $50.91%{\sim}65.72%$ moisture. 2. The quantities of protein amino acids in duck-meat were determined. 6.10% alanine. 2.75% valine, 7.13% glycine, 2.20% iso-leucine, 4.54% leucine, 4.90% proline, 5.80% threonine, 1.15% methionine, 3.20% hydroxy proline, 3.01% phenylalanine, 6.70% asparticacid, 12.71% glutamic acid, 4.95% lysine, 1.11% arginine, 5.60% histidine, 4.40% cystine+cystein, and serine and tyrosine in trace amount. 3. Except tryptophane, almost all the essential amino acids were analyzed.
