Abstract

Pysicochemical and sensory characteristics of cookies with various levels of functional rice flour were investigated in this study. Dough pH of 10% substituted group and Spreadability of 20 and 30% substituted group had significantly higher values than that of control group. Density of Dough had significantly the largest value of 1.27 with 10% substituted sample group. The L value of brightness in control group had significantly the largest value of 69.31. The b value of 20% substituted sample group had significantly the largest value of 35.60. Results of sensory characteristics showed significantly higher savory aroma, savory flavor, hardness and brownness with 10% substituted sample group. Acceptance test of cookies with 20% substituted sample group showed higher overall acceptability than those of others. Quality caracteristics of 10 to 30% subsituted sample groups indicated significantly similar or higher values compared to those of control showing the possibilities of developments in health concerned funtional rice coopkies.

본 연구에서는 기능성 쌀을 이용한 쿠키를 개발하여 이화학적 관능적 품질 특성을 조사하였다. 반죽의 pH는 기능성 쌀가루를 10% 대체한 반죽이 대조군 보다 유의적으로 높은 pH를 나타내었다. 쿠키의 퍼짐성에서는 20%와 30% 대체한 시료군이 대조군 보다 유의적으로 높은 퍼짐성을 보였다. 시료군의 L값은 대조군이 69.31으로 가장 높았으며, b값은 20%대조 시료군이 35.60의 값으로 가장 높았다. 기능성 쌀가루를 다양한 수준으로 대체한 쿠키의 관능검사를 실시한 결과 기능성 쌀가루를 10% 대체한 시료군이 고소한 냄새, 고소한 맛, 경도, 색의 갈색정도에서 유의적으로 특성이 강하게 평가되었다. 쿠키의 기호도 검사 결과 쿠키의 전반적인 기호도에서 기능성 쌀가루를 20%와 30% 대체한 시료가 대조군과 함께 유의적으로 높은 기호도를 나타내었다. 따라서 기능성 쌀가루로 대체된 쿠키는 모든 대체비에서 대조구와 비교하였을 때 유의적인 차이가 없거나 유의적으로 높은 기호도를 나타내어 기능성 쌀쿠키 개발의 가능성을 보여주었다.
