Abstract In order to enrich the experiment of real problem situations from real life, four common foods (Nestle coffee mate, white rabbit toffee, Dove white chocolate and household vegetable oil) were used as substrates. The common functional groups were analyzed through the ingredient list of each substance, and the corresponding groups were tested by the reactions of newly produced copper hydroxide, alkaline hydrolysis and iodine addition. Experiments show that the inspection phenomenon is obvious, the inspection time of each functional group is less than 1 min, the dosage is small, and the process is safe and controllable.
