Abstract

The sensory and safety of cook-chilled Buchu-jeon were evaluated to provide to foodservice operation during chilled storage for 5 days. The sensory evaluations of cook-chilled Buchu-jeon were conducted according to 3 reheating methods which was frying pan, steam/convection oven and microwave oven. The sensory evaluations were made on 4 sensory attributes (taste, odor, color, and texture) by a 9-member panel using quantitative descriptive analysis (QDA). The Buchu-jeon reheated in the steam/convection oven, after 1 day storage at $3^{\circ}C$, obtained higher score in taste, odor and texture than the ones reheated in a frying pan and microwave oven. Three reheating methods didn't show any difference in taste, odor, color, and texture of Buchu-jeon at $3^{\circ}C$ for 3 days. The Buchun-jeon reheated in microwave oven at $3^{\circ}C$ for 5 days had a significant $(p\leq0.05)$ lower score odor and color than the ones reheated in frying pan and steam/convection oven. The safety of Buchu-jeon was also evaluated by measuring total count, coliform count, psychrotrophic count, acid value and peroxide value during 5 days of storage periods at $4^{\circ}C$C. Total counts of Pajeon was ranged from $5.0\times10^{1}$ CFU/g to $2.2\times10^{2}$ CFU/g and the coliform and psychrotroph were not detected at most experiments. The acid values were ranged from 1.80 to 2.18 mg of KOH/g of fat until 5 days at $4^{\circ}C$. And the peroxide values were ranged from 4.44 to 17.87 meq of peroxide/kg of fat until 5 days of storage period. Therefore, these results demonstrated that the cook-chilled Buchu-jeon is microbiologically and chemically safe during 5 days of storage period at refrigeration temperature.

단체 급식소에서 부추전의 활용도를 높이기 위해 cook-chill 처리한 부추전을 개발하여 5일간 $4^{\circ}C$에서 냉장 저장하는 동안 후라이 팬, steam/convection oven, 전자렌지를 이용하여 재가열한 후 관능평가를 수행하였고 저장기간에 따른 안전성에 대해 평가하였다. 재가열 방법에 따른 차이에서, 냉장 1일 저장 후 맛, 냄새, 질감에서는 재가열 방법에 다른 유의적인 차이를 보이지 않았으나 전자렌지를 이용한 경우, 냄새에서 유의적$(p\leq0.01)$으로 낮은 점수를 나타냈다. 3일 저장 시에는 전반적으로 후라이 팬에서 재가열한 부추전이 steam/convection oven과 전자렌지에서 재가열한 부추전보다 높은 관능평가 점수를 보였지만 맛, 냄새, 색상에서는 유의적인 차이를 보이지 않았다 냉장 5일 저장한 부추전은 전자렌지를 사용한 경우, 맛, 냄새, 색상에서 유의적 p($\leq0.05)$으로 낮은 관능평가 점수를 나타냈다. 냉장 저장기간에 따른 차이에서 후라이 팬을 사용하여 재가열한 경우, 냉장상태로 5일간 저장하는 동안 모든 관능 특성에서 유의적인 차이를 보이지 않았다. Steam/convection oven에서 재가열한 경우 질감에서만 저장 5일에서 유의적$(p\leq0.05)$으로 낮은 관능평가 점수가 나타났다. 전자렌지로 재가열한 경우 맛과 냄새 항목에서만 저장 5일에서 유의적$(p\leq0.01)$으로 낮은 관능평가 점수를 보였다 Cook-chill부추전의 안전성 평가에서 냉장 저장하는 5일 동안 실험 결과 총균수는 약 10$^{1}$에서 $10^{2}$ 사이의 수치가 관찰되었다. 대장균군과 저온성균은 실시된 대부분의 실험에서 검출되지 않았으나 저온성균만이 3일째 실험에서 소수가 검출되었다. 산가인 경우 냉장저장기간 동안 2.18이하의 적은 범위로 증가하여 안전성에는 큰 문제가 없는 것으로 확인되었고 과산화물가도 수치가 낮아서 안전성에는 문제가 없는 것으로 확인되었다. 따라서 cook-chill system을 이용하여 제조한 부추전에서 냉장 저장기간 동안 미생물적 그리 고 화학적인 안전성은 큰 문제가 없는 것으로 확인되었다
