Biogenic amine sensors and its building materials: A review

In an overpopulated world, food transportation and distribution must be continuously improved to avoid food waste. Between production and consumption, there is a period of handling, transport and storage, which can directly influence the final product quality. The spoilage processes generate food waste, which increases the demand for more production. The use of sensors is a crucial factor to improve food quality control. In this review, whose time period covered by the review is from 2015 to 2022, the relevance of the determinations of amines is presented, with emphasis on biogenic amines (BA), present in food and beverages mainly as a result of deterioration by the decarboxylation of amino acids. BAs, when ingested in high concentrations can cause several harmful effects on human health. Thus, the evaluation of maximum permitted concentrations is extremely important. Due to its importance in terms of food quality and safety, examples of sensors and their molecular mechanisms responsible for generating response are discussed. In addition, the use of polymeric materials for the construction of sensors will also be discussed, which play an important role and show promise in the field of sensor science and technology.
