초록

일반스펀지케이크 반죽에 대두유와 버터를 20, 40 및 60%의 비율로 첨가하며, 첨가시 유지 온도를 각각 20, 35, 60 및 $80^{\circ}C$로 달리하여 제조하였을 때 케이크 반죽 및 케이크의 특성을 관찰하였다. 유지 첨가시 온도가 낮을수록 또한 첨가비율이 높을수록 케이크반죽의 비중이 높게 나타나는 결과를 보였고, 대두유에 비해 버터를 첨가했을 때 케이크반죽의 비중이 높게 나타났다. 유지의 첨가비율이 높고 온도가 낮을수록 케이크의 부피 및 비용적이 감소되는 것으로 나타났다. 대두유의 경우 첨가량이 많을수록 온도가 높을수록 굽기 손실은 줄어들었고, 대두유와 버터를 같은 양으로 같은 온도에서 첨가할 경우 대두유의 굽기 손실이 버터에 비해 작았다. 수분함량은 첨가온도에 따라 유의할만한 차이는 보이지 않았으나 유지 첨가량이 높아질수록 유의적으로 수분 함량이 낮아졌다. 대두유와 버터의 첨가시 L, b값은 유의할 만한 차이를 보이지 않았으나, a값은 버터의 첨가비율이 증가됨에 따라 현격한 차이를 보였다. 케이크의 경도는 40%정도의 첨가량과 $80^{\circ}C$의 온도에서 가장 낮은 값을 보였다. 즉, 부피 및 비중은 20%의 비율로 $80^{\circ}C$의 온도로 첨가하였을 때가 가장 대조군과 비슷한 수치를 나타냈지만, 무게는 20, 40%에서 유의차를 나타내지 않았으며, 유지의 첨가 목적인 조직을 부드럽게 하는 특성은 대두유를 40%의 비율로 $80^{\circ}C$에서 첨가할 때 가장 적절한 배합비로 나타났다.

The purpose of this study was to examine the quality variations of cake and cake batter when either butter or soybean oil was added in plain sponge cake batter. Soybean oil or butter was added to the batter at ratios of 20, 40, and 60% at 20, 35, 60, and $80^{\circ}C$. The physico-chemical properties of cake batter and cake were measured to evaluate the effects of ratio and temperature of butter and soybean oil. At higher ratios of butter or soybean oil and lower temperatures, the specific gravity of the cake batter increased while the interrelations among weight, volume, and specific loaf volume decreased. L- and b- values were the same, but a-value increased remarkably with higher ratios of butter. The effect of adding butter or soybean oil on hardness was shown to be lowest at 40% and $80^{\circ}C$. Baking loss in the baking process with soybean oil decreased with increasing oil quantity and temperature. Moisture content did not change with temperature, but did decline with increasing amounts of butter or soybean oil. These results show that the optimum condition for sponge cake would be 40% soybean oil at $80^{\circ}C$.
