Abstract

Quality attributes of reconstructed pork patties with ISP were evaluated. Reconstructed pork patties with 30% meat plus ISP and 50% meat plus had significantly less cooking loss and dimensional changes than control. Sensory evaluation revealed patties with 30 or 50% meat had higher hardness and juiciness than control, patties with ISP, and patties with direct addition of ISP. Objective elasticities of patties with 30 or 50 % meat were high, whereas patties without ISP had higher values of hardness, gumminess, and chewiness. Color of patties with 30 or 50% meat were different from that of control. These result show addition of ISP to meat emulsion for pork patties markedly improved cooking loss, dimensional changes, hardness, and juiciness. When pork patties and cutlets prepared according to meat (30%) formula were frozen, cooking loss was significantly higher in slow-frozen patties, but freezing rate did not affect dimensional changes of patties and cutlets. Slow-frozen patties had higher hardness, but other textural properties were affected by the freezing rate. Quality of pork cutlets was not significantly changed by the freezing rate.

재구성 돈까스 패티 제조시 돼지고기 대체원료로 사용되는 ISP의 첨가방법을 기존방법과 다르게 하여 패티의 특성을 조사하고, ISP 첨가방법으로 가장 적당한 방법으로 제조한 패티와 돈까스를 급속 및 저속냉동하여 냉동속도가 품질 특성에 미치는 영향을 조사한 결과를 요약하면 다음과 같았다. ISP 처리구의 단백질함량은 대조구와 별 차이가 없었고, pH나 보수력에도 유의성 있는 차이가 없었다. 패티의 가열 감량이나 외형변화는 meat(50%)나 meat(30%) 처리구에서 대조구보다 낮았다. 패티의 기계적 견고성은 meat(50%)나 meat(30%) 처리구가 대조구와 함께 낮았으며, 관능적 다즙성은 높았다. 이들 결과로 보아 ISP 첨가시 기존의 fat emulsion complex로 이용하는 방법 대신에 meat emulsion complex로 이용하는 것이 패티의 품질특성을 개선하는데 도움이 되었다. Meat(30%) formula로 패티와 돈까스를 만들어 냉동한 결과 저속냉동 시 외형변화는 많았으나 유의성이 없었고, 가열감량은 유의성 있게 높았다. 패티의 견고성은 저속냉동한 것이 유의성 있게 높았으나 다른 테스쳐 특성에는 차이가 없었다. 그러나 돈까스의 경우에는 냉동속도가 텍스쳐 특성에 별 영향을 미치지 않는 것으로 평가되었다.
