A comprehensive overview of the principles and advances in electronic noses for the detection of alcoholic beverages

Abstract

Background

The rapid expansion of the alcoholic beverage market has emphasized the critical importance of ensuring product quality and safety. While traditional methods for alcohol detection are accurate, they often entail time-consuming procedures and require specialized equipment. In contrast, electronic nose (E-nose) technology has emerged as an effective mechanical olfaction system, offering advantages in terms of speed, sensitivity, and operational simplicity for assessing alcoholic beverages.

Scope and approach

This review begins with a comprehensive introduction to the history, architecture, and detection principle of the E-nose, followed by an enumeration of various E-nose systems used in alcoholic beverage detection. Subsequently, contemporary applications of E-nose technology in the detection of specific alcoholic beverages are examined, emphasizing its efficacy in identifying aromatic compounds and its integration with complementary technologies. By employing appropriate gas sensors, the E-nose can accurately replicate the human olfactory system, facilitating real-time classifying samples of alcoholic beverages into different groups.

Key findings and conclusions

The implementation of E-noses technology not only aids producers in controlling the quality of alcoholic beverage products but also enhances consumer safety in beverage selection. Moreover, the advancement of E-nose technology has contributed to the standardization and normalization within the alcohol industry. Finally, while the prospects for E-nose applications in alcohol detection are promising, several challenges persist, and the concluding section addresses future research for E-nose technology.
