비트 분말을 첨가한 스폰지 케이크의 품질특성 및 저장 기간에 따른 노화 억제 효과

Abstract

Purpose: This study investigated quality characteristics and retarding retrogradation of sponge cake added beetroot powder. Methods: Sponge cakes were prepared using 0%, 2%, 4%, 6%, and 8% of beetroot powder. The specific capacity, baking loss, and dough yield were calculated. Moisture content and pH were also measured. Color values were assessed using a color measurement spectrophotometer. The retarding retrogradation was calculated employing the Avrami equation. Results: The specific capacity increased in parallel to the addition of beetroot powder’s elevation, but baking loss significantly decreased. The dough yield was high in 6% and 8% additions however moisture content did not differ. The pH was increased in 0-4% additions. L and b-values significantly decreased according to the level of beetroot powder. For retarding retrogradation, a 4% addition had the effect of delaying the sponge cake’s staling. Conclusion: These results suggested that the beetroot can be considered a good material to improve the quality characteristics, sensory properties, and after the addition of 4% of beetroot powder was able to delay staling. Therefore, so it is assumed to improve the sponge cake shelf life.
