초록

본 연구는 가열처리와 온도가 구운 계란의 품질에 미치는 영향을 구명하고자 수행하였다. 구운 계란은 80, 90, 100, 105 및 $110^{\circ}C$ 의 온도에서 시간을 달리하여 5, 6, 7 및 8시간 동안 상업용 가열기(OF-22, JEIO TECH, Korea)를 이용하여 제조하였다. 가열감량은 최종 $110^{\circ}C$에서 가열된 8시간 처리구가 최종 $105^{\circ}C$에서 가열된 처리구들에 비해 유의적으로 (p<0.05) 높게 나타났다. 난백의 pH는 가열시간이 가장 짧은 5시간 처리구가 다른 처리구에 비해 유의적으로(p<0.05) 높게 나타났다. 난황의 pH는 모든 처리구 사이에 유의적인 차이가 없는 것으로 나타났다. 가열온도와 가열시간에 따른 구운 계란의 경도와 응집성은 처리구간 유의적인 차이가 없는 것으로 나타났다. 최종 $110^{\circ}C$에서 가열된 8시간 처리구의 백색도 값은 최종 $105^{\circ}C$에서 가열된 처리구들에 비해 유의적으로(p<0.05) 낮고, 적색도와 황색도의 값은 유의적으로(p<0.05) 높게 나타났다. 난백 및 난황의 수분 함량은 가열시간 증가와 함께 감소하는 경향을 나타내었다. 이상의 결과를 종합해 볼 때 구운 계란의 제조를 위한 적합한 시간은 8시간이며, 최종 온도는 $105^{\circ}C$에서 5시간 이상 또는 $110^{\circ}C$에서 2시간 이상 가열하는 것이 적절한 것으로 사료된다.

This study was conducted to investigate the effect of heating temperature and time on the quality of baked egg. Eggs were baked at various temperatures (80, 90, 100, 105 and $110^{\circ}C$) for different times (5, 6, 7 and 8 h) using a commercial heater. Our results revealed that heating loss in the $110^{\circ}C$ treatment was significantly (p<0.05) higher than those of other remaining treatments. The pH value of egg white in the 5 h treatment was significantly (p<0.05) higher compared to those of other treatments. While, no significant differences in pH values of egg yolks occurred among the treatments. Regarding the texture, hardness and cohesiveness values were not significantly different among the treatments. Regarding color, the $110^{\circ}C$ treatment samples had lower lightness value whereas had higher redness and yellowness values compared to the $105^{\circ}C$ treatments (p<0.05). Moisture content of baked eggs showed an decreased tendency as increasing the heating temperature and time. These results suggested that the proper conditions were 8 hours for total baking time including more than 5 h at $105^{\circ}C$ or 2 h at $110^{\circ}C$.
