“…Chen et al [77] have employed chemometrics and IR spectroscopy integrated with information from digital labelling to develop a means of rapidly detecting fraudulent liquors, for the presence of methanol, which is the most important and difficult adulterant to detect with accuracy. The spectral bands of methanol were labelled using iterative discrete wavelet transform for classification, and PCA and PLS analysis were then applied to discriminate problematic samples using the iterative discrete wavelet transform filtered signals.…”

Food fraud and adulteration is a major concern in terms of economic and public health. Multivariate methods combined with spectroscopic techniques have shown promise as a novel analytical strategy for addressing issues related to food fraud that cannot be solved by the analysis of one variable, particularly in complex matrices such distilled beverages. This review describes and discusses different aspects of whisky production, and recent developments of laboratory, in field and high throughput analysis. In particular, recent applications detailing the use of vibrational spectroscopy techniques combined with data analytical methods used to not only distinguish between brand and origin of whisky but to also detect adulteration are presented.

“…Nowadays, the global alcohol market is fast-growing; however, liquor counterfeit has also developed into one of the global economic criminal activities. e counterfeit liquor not only disturbs the order of the normal market management but also infringes the rights and interests of the regular manufacturers and consumers [1]. According to a survey on counterfeit liquor released by Chinese liquor industry media, a large number of consumers have bought counterfeit liquor (https://www.sohu.com/a/ 455700115_120133372).…”

In this paper, a handheld liquor authenticity detection system is demonstrated based on the laser spectroscopy technique, which consists of a handheld laser spectrometer and a mobile phone display terminal. In this system, the semiconductor laser is integrated into the spectrometer and the laser beam is further angled to the optical axis of the spectrometer to avoid interference of the fluorescence generated by the bottle wall. During the system operation, the laser excites the tested liquor to generate fluorescence and Raman spectroscopy signals, which are digitized and wirelessly transmitted by Wi-Fi to the Android mobile terminal. After the image processing by the mobile phone APP, the tested liquor spectrum curve is obtained. At the same time, based on the standard liquor spectrum curve stored in the database, the Pearson correlation coefficient is calculated and the matching similarity is given. In addition, this paper proposes a calibration method based on pure water Raman intensity to achieve accurate measurement of fluorescence intensity and minimize the influence of fluorescence intensity saturation on the measurement results. In the experiment, we measured the similarity of 12 brands of Chinese liquor by using our self-developed handheld laser spectrometer. Their authenticity of liquor could be given accurately and effectively.
