Abstract

The replacement of wheat flour with 4 to 24% soy fiber FIBRIM(R)1450 was evaluated to determine its effect on the properties of sponge cake. The volume and specific loaf volume decreased as the amount of soy fiber increased. In addition, the protein content and water holding capacity (WHC) were negatively correlated with the specific gravity of batter and the specific loaf volume of sponge cake, whereas there was no correlation between the mixograph characteristics and specific loaf volume of sponge cake in response to the addition of soy fiber. Furthermore, the symmetry and uniformity indices were not influenced by the addition of soy fiber. However, the L values of sponge cake crust and crumb decreased with increasing amounts of soy fiber, whereas a and b values were not affected. Additionally, the hardness, gumminess, and chewiness of the sponge cake all showed positive correlations with the protein content, sedimentation value, WHC and alkaline water retention capacity. Finally, the results of sensory evaluation indicated that external and internal colors, grain, texture, and flavor were not influenced by the addition of soy fiber, but that supplementation with over 20% soy fiber resulted in a slight decrease in taste and overall acceptability.

밀가루에 콩섬유 FIBRIM(R)1450을 4-24%까지 첨가한 결과 콩섬유의 첨가량이 증가할수록 스펀지 케이크의 부피와 비용적은 유의적으로 감소하였다. 단백질 함량과 보수율은 반죽의 비중 및 스펀지 케이크의 비용적과는 각각 부의 상관이 있었으나, Mixograph 특성과 케이크의 비용적 사이에는 상관관계가 존재하지 않았다. 스펀지 케이크의 symmetry index와 uniformity index는 콩섬유의 첨가량에 상관없이 일정한 값을 나타내었다 케이크 크러스트와 크럼의 L값은 콩섬유의 첨가량이 증가할수록 감소하는 경향을 보였으나 a값과 b값은 큰 차이를 나타내지 않았다. 스펀지 케이크의 경도, 검성과 씹힘성은 콩섬유의 첨가량이 증가함에 따라 약간 증가하는 경향을 나타내었다. 스펀지 케이크의 경도, 탄성, 검성 및 씹힘성은 단백질 함량, 침전가, 보수율 및 알칼리수 흡수율과는 정의 상관이 있는 반면, Pelshenke값과는 부의 상관을 나타내었다. 콩섬유를 첨가한 복합분의 스펀지 케이크 관능검사 결과, 외부 색깔, 기공, 조직감, 내부 색깔, 향기 등은 콩섬유의 첨가에 통계적으로 유의적인 영향을 받지 않았으나 맛과 전체적인 기호도는 콩섬유를 20% 이상 첨가하였을 때 약간 저하됨을 알 수 있었다.
