More Details: ObjectiveTo establish a fast, sensitive, and accurate method for detecting carmine.MethodsUsing Folium Nelumbinis; as the carbon source, carbon dots (FN-CDs) were prepared using a solvent thermal method, and the preparation conditions were optimized using a single factor test. Study the factors that affect the fluorescence intensity of FN-CDs, the effects of coexisting substances on the detection system, and optimize the measurement conditions; Using FN-CDs for the determination of carmine content in food and exploring its mechanism of action.ResultsUsing 0.6 g of Folium Nelumbinis, 0.25 g of citric acid and 45 mL of formamide were reacted at 240 ℃ for 4 hours, and the fluorescence value of FN-CDs was the strongest. Rouge had a good linear relationship within the concentration range of 0~70 µg/mL, with an R2 of 0.996 4 and a detection limit of 0.57 µg/mL. The spiked recovery rates of grapefruit juice beverage and canned arbutu were 88.09%~102.49% and 97.73%~112.47%, respectively.ConclusionThis detection method has the characteristics of high sensitivity, good selectivity and high accuracy, and can be applied to the rapid detection of carmine in food.
