삼겹살을 먹을 때, 동물성 지방의 섭취를 줄일 수 있는 효과적인 조리방법을 제시하기 위하여 삼겹살을 삶기, 찌기, 굽기 및 튀기기의 방법으로 가열조리한 후, 물리화학적 특성의 변화를 조사하였다. 가열조리에 의하여 전체적으로 수분 양은 감소하고 지질 양은 증가하였는데, 이에 따른 가열감량, 탈수량 및 탈유량은 튀기기와 삶기 처리구에서 높았다. 시료의 pH는 삶기 처리구에서 가장 많이 증가하였고, 시료로부터 추출한 지질의 산가와 굴절율은 튀기기 처리

This study was carried out to suggest an effective cooking method for pork bellies to decrease intake of animal fat. The physico-chemical characteristics of pork bellies cooked by different methods (boiling, steaming, baking and frying) were investigated. The moisture contents of cooked meats decreased but crude lipid contents increased. The cooking losses, moisture drain rates, and lipid drain rates were high after frying and boiling. The pH values increased markedly with boiling and both the acid value and the refraction index of the fat significantly increased with frying. The hardness, gumminess, and chewiness of the meat increased considerably with boiling, but decreased notably after frying. The springiness decreased very much with boiling and cohesiveness greatly increased with steaming. The CIE (lightness) value increased notably with steaming but decreased markedly with frying. The CIE (redness) value decreased markedly with all cooking methods, especially boiling, and the CIE (yellowness) value decreased with both boiling and steaming but increased with both baking and frying. The fatty acids of fat from the raw pork bellies were primarily oleic acid (42.4%), palmitic acid (23.9%), and linoleic acid (16.1%). The ratio of total monounsaturated fatty acids to total saturated fatty acids was 1.190 and the ratio of total polyunsaturated fatty acids to total saturated fatty acids was 0.446. In addition, the composition of fatty acids was not significantly changed with any cooking method except frying. Therefore, boiling is the effective cooking method for pork bellies to decrease intake of animal fats.
