Danger of melamine is that melamine would react with cyanuric acid to form melamine cyanurate crystals. These crystals form kidney stones in children causing kidney failure. Several children in China had died due to melamine-contaminated milk.
Melamine addition to food product would cause protein testing to indicate a higher level of protein. This is because the popular protein testing relies on testing of N (nitrogen). Melamin has a high of 66% of nitrogen.
Can you see the point?
Melamine is an organic base and a trimer of cyanamide, with a 1,3,5-triazine skeleton. Like cyanamide, it contains 66% nitrogen by mass and, if mixed with resins, has fire retardant properties due to its release of nitrogen gas when burned or charred, and has several other industrial uses. Melamine is also a metabolite of cyromazine, a pesticide.
Melamine is formed in the body of mammals who have ingested cyromazine. It has been reported that cyromazine can also be converted to melamine in plants.
Melamine combines with cyanuric acid to form melamine cyanurate, which has been implicated in the Chinese protein export contaminations.
