Abstract

Four kinds of polyphosphate solution(0. 1.5, 3.0 and 4.5%) were injected by 10% into pork loin such that polyphosphate could be added by 0% (water, control), 0.15%, 0.30% and 0.45%, respectively. Then, the effect of adding polyphosphate to pork loin was investigated after it was refrigerated at 4$\^{C}$ for 2 days and boiled until its internal temperature became 75$\^{C}$ and 80$\^{C}$. The pork loin that was boiled with polyphosphate added showed better water holding capacity, texture, and sensory juiciness than control group, but it produced lower pork flavor and strong abnormal flavor. As the internal temperature became higher, the pork loin showed higher cooking loss, worse tenderness and juiciness, and better pork flavor. This study demonstrates that the water holding capacity and palatability of boiled pork loin can be improved by the addition of about 0.15-0.30 g of polyphosphate per 100 g of meat.

돼지 등심육에 0%(물), 1.5%, 3.0% 및 4.5%의 인산염용액을 10%씩 주입하여 인산염을 각각 0%(대조구), 0.15%, 0.30% 및 0.45% 첨가되도록 하였다. 이것을 2일간 냉장한 후 중심온도 75$^{\circ}C$와 8$0^{\circ}C$가 되도록 삶아서 인산염 첨가효과를 검토하였다. 인산염을 첨가하여 삶은 등심육은 모두 대조구에 비해서 보수력, 조직감 및 다즙성이 향상되었다. 그러나 풍미가 약해지고 이상취가 느껴졌다. 등심육의 중심온도가 높아지면 가열감량이 많아지고 연도와 다중성이 저하되지만 풍미가 좋아졌다. 삶은 돼지 등심육의 보수력 및 기호성을 향상시키기 위해서는 인산염을 0.15%~0.30% 첨가하는 것이 좋았다.
