The recent “melamine†milk powder incident has made food safety a focus of attention. On the first day of the “6·18†campaign, the “Melamine Rapid Detection Reagent Card†independently developed by the School of Biological Science and Engineering of Fuzhou University in Hall A of Jinshan Exhibition City attracted a lot of people.
The reagent card is small and light, with only one chewing gum size, with the words C, T, S and so on. C stands for Control (control line), T stands for Test, and S stands for Sample. Each letter has a corresponding groove on its side. Just drop 3 drops of milk into S and drop the diluted droplets into it. The answer will be given at T. If milk does not contain melamine, a red line will be displayed at T, whereas if milk contains a large amount of melamine, the red line at T is not displayed. The entire test process takes less than 5 minutes and is simple and easy to operate. It is understood that the reagent card is a one-time product and the current market price is 18 yuan.
