Abstract

Pork belly(PB) and pork shoulder(PS) parts were tested to find out chemical and physical characteristics and sensory evaluation with various cooking methods such as pan heating, boiling, grilling, steaming, charcoal heating, pan heating and double-layer pan filled with phase change material (PCM) cooking. The moisture contents of steamed PB and PS had higher results of 60.2% and 67.2% than other treatments. The highest results of crude fat contents in PB treatments was charcoal roasting as 33.2% (p<0.05) while grilling resulted the highest at 16.0% in the PS (p<0.05). In the crude protein contents, boiling treatment resulted the lowest at 15.4% while steaming was the highest at 18.9% in PB. Also, crude protein content of grilling treatment was 25.2%, a result significantly higher than in other cooking methods in PS. Heating loss, which has a close relationship with water holding capacity, showed the highest result in the charcoal treatment at 40.18% and 39.68% each in the both of PS and PS. In the result of shear force, the lowest result was oven treatment at $2.76kg/cm^2$ in PB (p<0.05) and double-layer pan heating at $3.67kg/cm^2$ in PS (p<0.05). L value in the color test of boiling treatment showed the highest result of 65.16 and 59.72 in the PB and PS respectively (p<0.05), however it scored the lowest of 2.32 in b value in PB (p<0.05). In the 9 point-scale sensory evaluation, grilling treatment showed the highest result of 7.56 in the overall palatability of PB (p<0.05). However, PS in the pan heating which scored 7.22 was the best result while having the lowest score of 5.88 in the boiling treatment (p<0.05).

본 연구에서는 돼지고기 삼겹살과 목살의 가열처리방법에 따른 새로 개발된 PCM 처리와 이중팬을 제작하여 사용하였으며, 기존의 가열조리방법과 비교하여 이화학적 특성과 관능특성을 비교하였다. 돼지고기 삼겹살과 목살의 수분함량은 찌기처리구에서 60.2%, 67.2%로 높게 나타났으며, 조지방은 삼겹살은 숯불처리구에서 33.2%, 목살은 전기그릴처리구에서 16.0%로 가장 높았다(p<0.05). 조단백질의 경우, 삼겹살은 스팀처리구가 18.4%로 높았고, 삶기처리구는 15.4%로 유의적으로 낮았다. 또한, 목살은 전기그릴처리구에서 25.2%로 유의적으로 높게 나타났다(p<0.05). 보수력과 가장 관계가 깊은 가열감량은 삼겹살과 목살 모두에서 숯불구이처리구 40.18%, 36.98%로 유의적으로 높았고, 전단력에서 삼겹살은 오븐처리구에서 $2.76kg/cm^2$으로 목살은 이중 팬처리구에서 $3.67kg/cm^2$으로 가장 낮았다(p<0.05). 육색 시험결과 L값은 삶기처리구에서 65.16, 59.72로 가장 높았고(p<0.05) b 값의 경우, 삼겹살은 삶기처리구에서 2.32로 가장 낮았다(p<0.05). 관능평가 결과 전체적인 기호도 항목에서 삼겹살의 경우, 전기그릴처리구에서 7.56점으로 높았다. 목살은 팬구이처리구에서 7.22점으로 가장 높았으며, 반면, 삶기처리구에서 5.88점으로 가장 낮았다(p<0.05).
