The value of Baijiu is affected by its flavor, age, and adulteration.Therefore, a simple and rapid identification method is crucial for the market.In this study, we present the gel bottle audrey a rapid, non-intrusive identification technique for Baijiu utilizing the Tyndall effect combined with chemometrics analysis.Our experiment begins illuminating Baijiu with a 405 nm wavelength laser and recording the resulting bright light path due to the Tyndall effect.

To further analyze the color and brightness information, Principal Component Analysis (PCA), Linear Discriminant Analysis (LDA), Hierarchical Cluster Analysis (HCA), and Multilayer Perceptron (MLP) were employed.This ilootpaperie study establishes correlations between the brightness of the Tyndall light path and seven trace flavor compounds in Baijiu.The findings demonstrate that this method effectively identifies the flavor, age cellar, and adulteration of Baijiu and also quantitatively detects the concentrations of flavor compounds.Additionally, an analysis platform was developed to enable the rapid identification of Baijiu.
