Description

The increasing use of food colorants to improve the visual appeal of food products presents challenges in maintaining their safety and quality. While there are numerous safe, natural, and synthetic colorants available, the food industry frequently resorts to using banned dyes to cut costs and boost profits. Consequently, detecting food adulteration involving prohibited dyes is vital. This research presents a quick and effective fluorescence sensor designed to identify metanil yellow dye in water and real samples. A simple microwave-assisted hydrothermal technique was employed to produce carbon dots (CDs) using the leaf extract of Simarouba glauca, which detected metanil yellow dye within a concentration range from 100nM to 70 M. The fluorescence sensor developed displayed a linear response at lower concentrations, with a detection limit of 7.14nM. Additionally, the CDs identified metanil yellow dye in two popular Indian sweets, Mysore Pak and Laddu, achieving a recovery rate of 97.23%108.33% and 90.00%104.17%, respectively. Moreover, the CDs successfully detected metanil yellow dye in two brands of turmeric powder available in the market, achieving recoveries ranging from 94.44%110.00%. These results highlight the potential uses of these CDs in environmental monitoring and various sectors, including food and confectionery, utilizing metanil yellow dye. 2025 Wiley-VCH GmbH.
