Abstract

Development of chocolate products to improve the quality and functional properties with Bifidobacterium-fermented isoflavone powder (BFIP) was attempted. Effects of BFIP on sensory value, isoflavone contents, and microbiological characteristics of chocolate products during storage at room temperature $(24{\pm}0.5^{\circ})$ for 90 day were studied. Five different BFIP concentrations of 0, 1, 2, 3, and 4% (w/w) were added and blended into the chocolate products. Results of sensory evaluation showed that the scores for softness and bitter taste decreased as the BFIP contents increased. In sweet and sour taste, the highest score was shown at 1% BFIP treatment. In overall acceptability, 1% treatment was the most favored, followed by 2% treatment. Contents of isoflavone in chocolate products were stably maintained during 90 storage days. The viable cell numbers of Bifidobacterium remained relatively stable until 70 day, followed by a slow decrease thereafter in all treatments.

Bifidobacterium을 이용하여 이소플라본을 비배당체로 전환시킨 Bifidobacterium-fermented isoflavone powder(BFIP)를 실생활에서 쉽게 이용할 수 있도록 기능성 쵸코렛 제품을 개발하고자 BFIP의 첨가량을 0, 1, 2, 3, 4%(w/w)의 5가지 실험처리구로 달리하여 쵸코렛을 제조한 후 실온$(24{\pm}0.5^{\circ}C)$에서 90일 동안 저장하면서 관능적, 화학적 및 미생물학적 특성을 보았다. 관능평가 결과 BFIP가 많을수록 부드러운 정도가 좋지 않은 것으로 나타났고, 쓴맛을 많이 나타내어 낮은 점수를 받았다. 단맛과 신맛은 1% 처리구가 높은 점수를 받았고, 전반적인 기호도 결과 BFIP 1% 처리구를 가장 선호하였고, 그 다음으로 2% 처리구를 좋아하는 것으로 나타났다. 이소플라본 분석결과 처리구별로 저장 90일 동안 이소플라본 함량을 거의 유지하였다. 쵸코렛에 첨가된 Bifidobacterium 균수의 생존율을 경시적으로 조사한 결과 쵸코렛 제조후 첨가구별 Bifidobacterium 균수가 저장 70일까지 거의 유지되었고, 저장 80일과 90일에 모든 첨가구에서 약간씩 감소하였다. 연구결과 기능성 쵸코렛의 제조는 쵸코렛의 본래의 기호를 유지시킬 수 있는 BFIP 1% 처리구가 바람직한 것으로 나타났고, 기능성과 기호성을 생각한다면 2% 처리구까지 가능한 것으로 보였다.
