초록

이 연구에서는 식빵의 표준 묘사분석 절차를 확립하였으며, 그 결과, 식빵에서 23가지의 특성 묘사 용어를 선정하고 개발하였으며 평가 절차를 확립하였다. 개발된 표준 묘사분석 방법을 이용하여 숙성온도와 배합비가 다른 4종류의 식빵에 대해 관능적 특성을 평가한 결과, 4종류의 식빵 간에는 23개의 관능적 특성에서 모두 유의전인 차이(p<0.05)가 있었다. 따라서 이 실험에서 개발된 식빵의 특성 용어와 그 정의 및 평가 기술이 종류가 다른 식빵의 관능적 특성의 차이를 잘 설명탈 수 있음을 알 수 있었다. 앞으로 이와 같은 연구 결과가 식빵의 품질향상에 기여할 수 있으려면, 원료와 제조 방법에 따른 식빵의 품질평가에 묘사 분석이 적용되고, 이 결과와 소비자 기호도 검사 또는 기계적 측정 결과와의 상관관계를 분석하는 연구가 지속적으로 이루어져야겠다.

This study was conducted to develop the descriptive analysis procedures for evaluating the sensory characteristics of yeast leavened breads. Eleven highly trained panelists identified the following 23 sensory attributes in the bread and defined the terminology for each attribute; yellowness of crumb, roughness of surface, uniformity of cell, density of cell, brownness of crust for appearance characteristics, yeast fermented, chemical, roasted flour, buttery, milky, boiled flour, sweet, and salty for flavor characteristics, springiness, ease to tear, moistness on surface, adhesiveness to lip, hardness, stickiness, cohesiveness of mass, moisture absorption, chewiness, and loose particles for textural characteristics. Reference samples for the flavor attributes were determined. There were significant differences in all of the 23 sensory attributes of commercial bread samples. The principal component analysis (PCA) was performed to summarize the sensory data. The first two principal components explained 89% of the variation of the original variables indicating reliability of procedure developed in this study.
