Abstract
|
|
|
|
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.
