An Aromatic Lexicon Development for Soymilks

The aim of this work was to develop an aromatic lexicon for evaluating different soymilks with two descriptive methods and an instrumental assistance. A list of 20 terms was generated by eight trained panelists through gas chromatography olfactometry and mass spectrum with free choice profiling for three different soymilk samples. During this phase, panelists randomly used words they were familiar with to evaluate the aroma they experienced and then make an agreement on these terms. Data were analyzed via generalized procrustes analysis, two-way ANOVA, and high-frequency analysis to select the most suitable terms. Based on the above list, 14 panelists evaluated the three soymilk samples with citation frequency profiling. The panelists chose the terms from the list that they considered as the most appropriate way to describe the samples. The data were analyzed by corresponding analysis to verify the performance of the panel and chi-square (χ2) analysis to determine the discriminate descriptors, including m...
