Abstract

This study was carried out to investigate the influence of black rice powder addition on quality attributes of cookies. The cookies was made with various black rice powder concentration(3%, 6%, and 9%). The specific volume of cookies didn't show significant difference, and the width determined by the water content in the dough was decreased with increasing content of black rice powder. The L value in the cookies was significantly the largest value in the control group. The a and b values were the highest in the 9% substituted sample group. According to the sensory evaluation of cookies, the scores of color, flavor, and texture were raised by the addition of black rice powder. Overall acceptance of 6% cookies showed higher value than that of the 3% and 9%.

흑미분말 소프트 쿠키의 제과 적성을 파악하고자 쿠키 제조시 흑미 분말 첨가량을 3%, 6%, 9% 첨가하여 제조한 후 쿠키의 물리적 관능적 특성을 평가하였다. 흑미 분말 쿠키의 비체적은 대조구와 첨가구 사이에 유의차가 보이지 않았으며 반죽 내 수분함량에 의해 결정되는 퍼짐성은 첨가량이 증가할수록 낮은 값을 나타내었다. 색도 측정결과 첨가량이 증가할수록 L값은 감소하였으며, a값과 b값은 증가하였다. 특히 a값은 시료 간 유의차가 크게 나타났다. 관능검사 결과 쿠키가 맛, 풍미, 색깔, 조직감 등에서 흑미 분말의 첨가량이 증가할수록 높은 값을 나타내었으며 전체적 수용도에서 6% 첨가구에서 가장 높은 선호도를 나타내었다.
