Abstract

We evaluated the sensory properties of, and color change in, sponge cakes prepared with addition of rosemary powder at different levels (0, 0.1, 0.3, 0.5, and 0.7% [all w/w]). The color values (L, b) of sponge cakes decreased as the level of rosemary powder increased from 0% to 0.7%, but the a value increased. Sensory evaluation tests showed that the scores for color, sweetness, and appearance decreased as rosemary powder content increased, but the air bubble score did not decrease (p<0.05). Flavor and color intensity scores were highest in cakes with 0.7% (w/w) rosemary. However, the trend of color intensity decreased as rosemary powder content increased in this experiment. After 3 days of storage, sponge cake with added rosemary powder was softer than control cake. It is concluded that sponge cake with 0.1 or 0.3% (both w/w) rosemary powder is acceptable.

로즈마리 분말의 최적 첨가량을 찾기 위하여 항산화 효과와 항균력이 있는 건강기능성의 생리활성 소재인 로즈마리 분말을 첨가하여 제조한 스폰지 케이크의 색도와 관능적 특성을 보았다. 스폰지 케이크에 로즈마리 분말의 첨가량은 0, 0.1, 0.3, 0.5 및 0.7%(w/w)로 하였고, $20^{\circC$에서 3일간 저장하면서 색도, 기호도와 강도 특성의 변화를 측정하였다. 로즈마리 분말의 첨가량이 증가할수록 명도(L값)와 황색도(b값)는 낮아졌으나 적색도(a값)는 증가하여 첨가량에 따라 스폰지 케이크의 색이 어두워지며 적갈색으로 변하는 것을 알 수 있었다. 기호도 특성 결과 로즈마리 분말의 첨가량이 증가함에 따라 색, 단맛, 외관에 대한 기호도는 감소하였으나, 기공성은 유의차가 없는 것으로 나타났다. 로즈마리 분말 0.1% 첨가구가 외관, crust와 crumb의 색, 향기, 단맛, 전반적인 기호도에서 유의적으로 높은 점수를 받아 선호하는 것으로 평가되었다. 강도 특성 결과 로즈마리 분말 0.7% 첨가구에서 색과 냄새의 강도가 가장 강하게 나타났으며, 첨가량이 증가할수록 단맛의 강도는 낮아졌다.
