Abstract

This study investigated the quality changes of pound cake prepared with various concentrations of rice bran powder. Pound cake were prepared by addtion of 0, 5, 10, 20, and 30 powder to the flour of basic formulation. The specific gravity of pound cake decreased with rising powder concentration. The volume and weight and specific volume increased with rising powder concentration. The moisture of pound cake decreased with increasing powder concentration. With rising powder concentration, the a value of pound cake increased but the L and b values decreased. The texture, hardnessm cohesiveness, springness, gumminess, and chewiness of pound cake decreaed with rising powder concentration. The result of sensory evaluation when compared to pound cake with 20% rice bran powder was superior in taste, flavor, and overall preference.

다양한 생리활성 기능을 가진 미강 분말을 첨가하여 제조한 파운드케이크의 품질특성을 측정한 결과는 다음과 같다. 미강 첨가량을 달리하여 제조한 파운드케이크의 반죽에 대한 비중은 대조구가 0.78로 높게 측정되었으며 미강 첨가량이 증가함에 따라 감소하였다. 파운드케이크의 부피(mL)는 대조구가 612.50 mL, 30% 첨가구가 690.00 mL으로 미강첨가량이 증가할수록 높아졌으며 파운드케이크의 수분함량은 미강첨가량이 증가할수록 낮게 나타났다. 파운드케이크의 pH는 미강첨가 20%에서 6.91로 높게 측정되었으며 파운드케이크의 색도 측정값 중 명도와 황색도는 미강의 첨가량에 따라 낮아지고 적색도는 높아졌다. 파운드케이크의 조직감은 미강 첨가량이 증가하면서 경도와 점착성, 씹힘성이 감소하는 경향을 나타냈으며 미강의 지방함량이 경도의 변화를 감소시키는 것으로 생각된다. 파운드케이크의 관능기호도는 미강 20% 첨가구가 가장 좋은 기호도를 나타냈으며 미강 첨가 파운드의 제조 시에는 관능 기호도와 물성이 뛰어난 것으로 평가된 10%~20%의 미강을 첨가하는 것이 가장 적합할 것으로 생각된다.
