Abstract

The purpose of this study was to investigate the quality characteristics of cookies prepared with dropwort powder(0, 2, 4, 6, and 8%) for flour. The bulk density of cookie dough of groups with dropwort powder shows significantly differences when compared to the control group. The pH of cookie dough and cookies were decreased by addition of dropwort powder. The moisture content of the groups with dropwort powder was higher than that of the control group. The weight and width of the groups with dropwort powder was lower than those of the control group. The spread ratio of the groups with dropwort powder was lower but the loss rate of cookies was higher than those of the control group. In color, the L, a, and b value was decreased significantly by addition of dropwort powder. The hardness of the groups with 2% and 4% dropwort powder was higher than that of the control group. DPPH radical scavenging activity of the control group was 20.62%, whereas the groups with dropwort powder ranged from 32.11~65.10%. Sensory evaluation scores in terms of appearance, flavor, taste, texture, and overall preference of groups with 2% and 4% of dropwort powder did not show any significantly differences when compared to the control group. Based on the above results, using less than 4% of the dropwort powder would be proper to make cookies.

본 연구는 미나리의 활용방안을 증진시킬 목적으로 미나리 분말을 첨가하여 쿠키를 제조한 후 항산화 및 품질특성을 평가하였다. 미나리분말 첨가 쿠키 반죽의 밀도는 대조군이 미나리 분말 첨가군보다 높았고 쿠키 반죽의 pH는 미나리 분말 첨가군이 대조군보다 낮았다. 쿠키의 수분함량은 미나리 분말 첨가량이 많을수록 증가하였고 쿠키의 pH는 미나리 분말 첨가량이 많을수록 감소하였다. 쿠키의 중량과 직경은 미나리 분말 첨가군이 대조군보다 더 낮았다. 쿠키의 두께는 대조군과 미나리 분말 첨가군 사이에 유의적인 차이는 없었다. 쿠키의 퍼짐성은 미나리 분말을 첨가할수록 낮아지는 경향을 보였고 손실율은 미나리 분말 첨가군이 대조군보다 유의적으로 높게 나타났다. 미나리 분말 첨가 쿠키의 색도에서 명도 L값, 적색도 a값과 황색도 b값은 대조군이 미나리 분말 첨가군보다 더 높게 나타났다. 쿠키의 경도는 대조군보다 미나리 분말 2%와 4% 첨가군이 유의적으로 높게 나타났다(p<0.01). 쿠키의 DPPH 라디칼 소거능에 대한 결과, 대조군은 20.62%였으며, 미나리 분말 첨가군은 32.11~65.10%로 대조군보다 높게 나타났다(p<0.001). 쿠키의 기호도 검사에서 외관, 향, 질감, 맛과 전반적인 기호도는 대조군과 미나리 분말 2%와 4% 첨가군 사이에 유의한 차이가 없었다. 이상의 결과 쿠키제조 시 미나리 분말 첨가는 4% 이내로 첨가하는 것이 바람직할 것으로 판단되었다.
