A few days ago, the reporter learned from the School of Chemistry and Chemical Engineering of Lanzhou University that after the three professors of the college united in scientific research to solve the problems, it was able to quickly detect whether or not the food contained toxic and harmful substances--trimerization.
The cyanamide chemical reagents were developed.
According to reports, after repeated experiments, members of the research team added a chemical reagent that was developed to milk and other foods. Through food color changes, they can quickly determine whether the food contains
Poisonous and harmful melamine material.
[At the same time] Professor and Ph.D. supervisor Chen Baohua of the College of Chemistry and Chemical Engineering of Lanzhou University: ...If there is no melamine milk, it does not have this color reaction. ... This kind of detection
It takes about 20 minutes before.
[Explanation] It is understood that the research group will further improve the chemical reagents for rapid detection of melamine to achieve the requirements for the qualitative and quantitative requirements for the substances to be tested.
Easy to carry kits.
