Food analysis is significantly important in monitoring food quality and safety for human health. Traditional methods for food detection mainly rely on benchtop instruments and require a certain amount of analysis time, which promotes the development of portable sensors. Portable sensing methods own many advantages over traditional techniques such as flexibility and accessibility in diverse environments, real‐time monitoring, cost‐effectiveness, and rapid deployment. This review focuses on the portable approaches based on carbon dots (CDs) for food analysis. CDs are zero‐dimensional carbon‐based material with a size of less than 10 nm. In the manner of sensing, CDs exhibit rich functional groups, low biotoxicity, good biocompatibility, and excellent optical properties. Furthermore, there are many methods for the synthesis of CDs using various precursor materials. The incorporation of CDs into food science and engineering for enhancing food safety control and risk assessment shows promising prospects.

“…Fluorescent sensors for amine detection are popular due their high sensitivity, low cost, and ease of operation when compared to electrochemical based sensors. [79][80][81][82][83][84][85][86][87][88][89][90][91][92][93] However, these sensors rely on either illumination with specific wavelengths of light (generally UV) to determine a color change in emission by eye or camera or via analysis with equipment, such as a fluorimeter, that can measure the emission profile of the sensing material to determine the response status. It is unlikely that a fluorimeter will be a common piece of equipment in households, however, it could be that the common household would adopt UV-light flashlights that can illuminate such fluorescent sensors to obtain a reading.…”

“…Toloza and co-researchers prepared amino-functionalized carbon dots capable of detecting histamine in tuna fish under Fe 3+ mediation [33]. The pH-responsive carbon dots from N-acetyl-L-cysteine and citric acid were also reported combined with Rhodamine B to detect histamine and monitor food spoilage [34]. Considering the many sources to make CDs for detecting agent, however, the utilization of copper doping on CDs sourced from hyaluronic acid for the fluorescence detection of histamine has never been explored.…”

Determination of the histamine in food is a crucial aspect regarding its safety issue. The present study reported the preparation of copper-doped carbon dots (Cu-CDs) through the pyrolysis method and further applied them for sensitive histamine detection via UV-Vis absorption and photoluminescence (PL) techniques. Several characterizations, including X-ray diffraction, Raman, Infrared, and photoluminescence spectra, confirmed this nanomaterial's well-formed Cu-CDs and all-optical properties. While Photoluminescence spectra perform regular degradation of Cu-CDs emission, the absorption spectra also showed increasing peaks at 270 nm following the enhancement of histamine concentration introduced to Cu-CDs. The analytical method parameters were next used to evaluate histamine detection performance, where the Cu-CDs showed good accuracy and selectivity for detecting histamine with LOD and LOQ values as low as 19.20 and 64 mg/L, respectively. It also possessed a valuable recovery rate ranging from 89-106%. Even though UV-Vis Spectrophotometry successfully detected histamine, Cu-CDs maintained their photoluminescence properties, offering more distinct advantages, including low cost, simplicity, high sensitivity, and selectivity properties.
