한국에서 사육되고 있는 오리의 식용화를 검토하기 위하여 시도하였다. 시장에서 구입한 오리고기를 일반분석하여 수분 62.87%, 조단백질 19.06%, 조지방 17.05%, 회분 1.02%를 나타냈으며 오리고기 단백질을 GLC로 분석하여 거의 모든 필수아미노산이 함유되어 있음을 알 수 있었고 트리프토판이 제한 아이노산 이었다. 한편 오리고기의 지방산을 GLC로 분석하여 oleic acid가 많았고 linoleic acid도 상당량 함유되었음을 알 수 있었고 지방산의 P/S 비는 3.4를 나타냈다. 그리고 오리고기의 콜레스테롤 함량은 70.5mg%를 나타냈고 인지질도 많은 양이 함유되었으며 특히 레시틴이 많았다. 도살 후 2시간까지는 APT-phosphorus의 유리는 높은 온도에서 훨씬 빨리 되어지며, 근원단백질의 ATPase활성은 EDTA, 금속이온의 농도가 증가하면 억제를 받고 농도가 감소되면 활성은 증가되었다. 오리고기를 상이한 조건에서 조리하고 pepsin을 첨가하여 좋은 소화상태를 알 수 있었다. 이는 오리고기가 동물성 단백질이 풍부하며 소화도 잘 되므로 좋은 동물성 단백질원이 된다고 생각되어 진다.
Commercially available duck-meat was subjected to proximate analysis. On a wet basis, the duck-meat contained 62.87, 17.05, 19.06 ana 1.02 percent of moisture, crude fat, crude protein and ash, respectively. Almost all the essential amino acids contained in the duck-meat protein, ana the tryptophan was the limiting one by amino acid analysis of GLC. An analysis of the fatty acid composition by GLC showed a relatively high concentration of oleic acid. There was also a considerable content of linoleic acid. The content of polyunsaturated fatty acids of duck-meat was 70.9% and the P/S ratio of fatty acids was 3.4. The cholesterol content in duck-meat was determined to be approximately 70. 5mg/100g ofm sample. According to blood analysis, it was understood that the content of phospholipids was relatively high, particulary in lecithin. ATP-phosphorus, at the higher temperature, was released faster than at the lower temperature, by two hours after postmortem. The ATPase activity of Myogibril was inhibited at the relatively high concentration of added EDTA and metallic ions, but the activity was very high in the lower concentrations. According to the cooking conditions, boiled duck-meat showed good digestion by pepsin. It was understood that the digestibility of duck meat was relatively high, so the duck-meat protein is good source of animal protein. Therefore, it is able to be recommended that duck-meat is good nitrogen source animal food.
