Abstract

This study investigated the effects on the quality characteristics of the korean steamed rice cake, Seolgiddok of the addition of aloe powder at 0%, 1.5%, 3.0%, 4.5% and 6.0% and 4-days storage. The moisture content of the control 0% aloe, steamed rice cake was 47.76%, and steadily decreased with increasing powder addition to the lowest of 37.38% for the cake with 6.0% added. The moisture content was decreased with extending storage time in both the control and powder-added groups. The cohesiveness, springiness, adhesiveness, gumminess and chewiness of the cake tended to decrease with increasing powder content, while the hardness increased with both increasing powder content and extending storage time. The Hunter color value L in the chromaticity of the cake was significantly decreased with increasing powder addition. The a value of the control, 0% aloe steamed cake was -0.86, but became positive with red color with increasing powder content, The b value was significantly increased with increasing powder content. The powder addition inhibited the increase in bacteria number. The sensory characteristics of the cake. such as color, aloe flavor and taste, and bitterness were increased with increasing powder content, while the moist and soft feeling of the cake were more highly evaluated at lower powder content. The overall taste was judged to be best for the sample with 3% added powder. Accordingly, it was expected that a highly functional and healthy product with improved quality might be developed by the addition of aloe powder to the Korean steamed cake, Seolgiddok.

알로에가루 첨가량(0%, 1.5%. 3.0%. 4.5%. 6.0%)을 달리하여 제조한 알로에 설기떡을 4일간 저장하면서 기계적 품질특성과 관능적 품질특성을 평가하였다. 수분함량은 제조 직후 대조구가 47.76%였고, 알로에 가루 첨가량이 많아질수록 낮아져 6.0% 첨가가 37.38%로 가장 낮게 나타났다. 저장기간별로는 대조구와 첨가군 모두 저장기간이 길어질수록 수분함량은 감소하였다. 물성측정에서 응집성, 탄력성, 점착성, 부착성, 씹힘성은 가루 첨가량이 증가할수록 감소하는 경향을 보였고, 견고성은 알로에가루 첨가량이 많을수록 증가하였으며, 저장기간이 경과할수록 높아졌다. 색도에서 L값은 설기떡에 첨가한 알로에 가루량이 많을수록 유의적으로 감소하였고, a값의 경우 제조직후 대조구는 -0.86이었으며, 알로에가루 첨가량이 많을수록 양의 값을 나타내어 적색을 띠는 것을 알 수 있었고, b값은 알로에가루 첨가량에 따라 유의적으로 증가하였다. 총균수는 알로에가루의 첨가에 따라 총균수가 적게 나타났으며, 관능검사는 색, 알로에 향, 알로에 맛, 쓴맛의 경우 알로에가루 첨가량이 많을수록 관능적 특성도가 높게 나타났으며 반면 촉촉한 정도, 부드러운 정도는 알로에 가루 첨가량이 적을수록 높게 평가되었다. 전반적 기호도는 알로에 가루 3% 첨가구가 가장 기호도가 높은 것으로 나타났다. 따라서 설기떡에 알로에 가루를 사용함으로써 떡의 품질이 향상되어 건강 기능성 상품 개발이 가능할 것으로 예상되며 향후 알로에의 기능적 성분 분석 등의 연구가 부가되어 다양한 식품조리에 대한 응용연구가 이루어져야 하겠다.
