Acrylamide is a hazardous chemical mainly synthesized during the thermal processing of foods representing significant concern within broader issue food contaminants and their impact on public health. can be absorbed by human body through dietary intake, respiration, dermal contact, mucosa. The metabolic conversion acrylamide into mercapturic acid metabolites glycidamide results in several adverse toxic effects. Therefore, this review explores formation, toxicity, metabolism acrylamide. Hence, it crucial to detect ensure product quality via risk evaluation. Traditional analytical techniques for detection often require expensive instrumentation complex sample preparation, prompting exploration alternative, cost‐effective, sustainable methods. Here, we propose utilization carbon quantum dots (CQDs) green approaches as novel solution. CQDs display immense potential diverse applications due valuable properties such biocompatibility, photocatalysis, strong fluorescence. This highlights distinct fluorescence probe detecting acrylamide, showcasing efficacy addressing safety concerns. In addition, various extraction purification QuEChERS, solid phase extraction, Carrez clarification, dispersive liquid‐liquid microextraction are comprehensively reviewed. QuEChERS regarded most promising technique owing its rapid, higher recovery rates.

The synthesis of carbon quantum dots from high molecular weight biomass-derived precursors poses a significant challenge due to the complex structures and low conversion efficiency. This work demonstrates green, rapid, sustainable continuous hydrothermal flow (CHFS) approach for synthesising nitrogen-doped (NCQDs) various precursors, including polymeric sources like chitosan, lignin, humic acid. We find that precursor structure significantly impacts size fabricated NCQDs their optical properties. Citric acid, precursor, yields with excitation-independent emission, higher yields, non-radiative losses, while derived exhibit excitation-dependent, red-shifted, lower efficiency emission. Theoretical calculations, performed understand configuration distribution nitrogen dopants within NCQD structure, showed pyridinic graphitic atoms exhibited strong preference aggregate near centre edge not in vertices nor core, thus affecting HOMO LUMO, bandgap, light absorption emission wavelengths. life cycle assessment highlights green scalable advantages CHFS process, making it large-scale precursors.
