Synthesis of Fluorescent Carbon Dots from Glucose and Calcium Carbonate and Their Application in the Beverage

In this text, glucose and calcium carbonate are used as raw materials to prepare carbon dots using electric thermostatic drying oven. The synthesized carbon dots solution is used for pineapple beverage. The single factor experiment and orthogonal experiment are used to determine the optimum proportion of the beverage. The results showed that for pineapple beverage the optimum proportion is that white sugar is 6%, citric acid is 0.1%, and pineapple juice is 40%, and carbon dots solution is 2.5%. Under this condition, the best flavor of beverage was obtained. It is hoped that this study could provide some suggestions for the further application of carbon dots.
