The assessment of peroxides in food products plays a critical role in determining their oxidative deterioration and overall quality. Conventional methods for peroxide detection often involve intricate and time-consuming procedures, prompting a growing interest in developing efficient and rapid techniques for detecting peroxides in food. An emerging approach in this endeavor involves the use of heteroaromatic dyes within peroxide detection systems. Heteroaromatic dyes exhibit inherent reactivity towards peroxides, resulting in noticeable color changes or fluorescence signals, making them widely applicable in biosensors. This review article explores recent advancements in harnessing heteroaromatic dyes for biosensors tailored to peroxide detection in food. It examines the fundamental principles governing the interaction between heteroaromatic dyes and peroxides, emphasizing factors that influence sensitivity and selectivity. Furthermore, the review critically evaluates the advantages and limitations of utilizing these dyes for peroxide detection. Lastly, the article contemplates future prospects and potential research directions within this evolving domain.
