Instrumental analysis revealed differences in aroma components of Chinese steamed breads made with traditional sourdoughs from different origins. However, studies on the flavor characteristics of these breads using human olfactory perception are lacking. This study collected eleven Chinese steamed breads made with different traditional sourdoughs to develop a lexicon and a quantitative descriptive analysis (QDA) method for sensory evaluation. The QDA method accurately evaluated the intensities of flavor attributes, and cluster analysis categorized the breads into four groups based on their flavor characteristics.
Instrumental analysis showed that steamed breads made with Chinese traditional sourdoughs from different origins had different aroma components. However, the analysis of flavor characteristics of Chinese steamed breads (CSBs) using human olfactory perception was rarely reported. In this study, eleven CSBs made of different Chinese traditional sourdoughs were collected to develop a lexicon and a quantitative descriptive analysis (QDA) method suitable for the sensory evaluation of CSBs. A terminology lexicon consisting of 14 flavor attributes (the odors of cellar, sweet, alkaline, sour aromatic, butyric acid, sourdough, overripe and yeasty; the tastes of sweet, sour and acetic acid; the after-tastes of bitter, sweet and sour) was developed by 11 trained panelists. The QDA method was conducted to evaluate the intensities of CSB flavor attributes. Cluster analysis indicated that eight CSBs were divided into four categories: CSBs made of Shangqiu, Tanghe and Xi'an sourdoughs had a unique property of sour, CSBs fermented by Heze and Zhenping sourdoughs had rich sensory attributes, CSBs made with Minqin, Taian, Zhumadian, Weinan and Nanyang sourdoughs had bland flavor, and CSB fermented by Angel yeast had a prominent characteristic of sweet. QDA method was accurate and applicable for analyzing flavor characteristics of CSB.
