The World Health Organization (WHO) said melamine may be found "in a variety of milk and milk products at varying levels, from low ppb to ppm ranges". [20] One academic suggested cyromazine, a melamine derivative pesticide commonly used in China for a long time, is absorbed into plants as melamine; it may therefore have long been present in products such as poultry, eggs, fish, and dairy products.
Protein adulteration in China. In China, the adulteration and contamination of several food and feed ingredients with inexpensive melamine and other compounds, such as cyanuric acid, ammeline and ammelide, are common practice. These adulterants can be used to inflate the apparent protein content of products, so that inexpensive ingredients can ...
Melamine / ˈmɛləmiːn / ⓘ is an organic compound with the formula C 3 H 6 N 6. This white solid is a trimer of cyanamide, with a 1,3,5-triazine skeleton. Like cyanamide, it contains 66% nitrogen by mass, and its derivatives have fire-retardant properties due to its release of nitrogen gas when burned or charred.
The most common derivative of 1,3,5-triazine is 1,3,5-triazine-2,4,6-triamine, commonly known as melamine or cyanuramide. Another important derivative is 1,3,5-triazine-2,4,6-triol better known as cyanuric acid. Cyanuric chloride (2,4,6-trichloro-1,3,5-triazine) is the starting point for the manufacture of many herbicides such as Simazine and ...
Cyanamide is an organic compound with the formula C N 2 H 2. This white solid is widely used in agriculture and the production of pharmaceuticals and other organic compounds. It is also used as an alcohol-deterrent drug. The molecule features a nitrile group attached to an amino group.
Urea is Neo-Latin, from French urée, from Ancient Greek οὖρον (oûron) 'urine', itself from Proto-Indo-European *h₂worsom . It is a colorless, odorless solid, highly soluble in water, and practically non-toxic ( LD 50 is 15 g/kg for rats). [ 7] Dissolved in water, it is neither acidic nor alkaline.
Melamine contamination is confirmed after a sample was sent to a laboratory at University of California at Davis. Human food tests positive for melamine May 22, 2007. United States Department of Health and Human Services (DHHS) officials announce that melamine was detected in catfish imported to Arkansas from Asia for human food. The fish were ...
A well known triazine is melamine (2,4,6-triamino-1,3,5-triazine). With three amino substituents, melamine is a precursor to commercial resins. Guanamines are closely related to melamine, except with one amino substituent replaced by an organic group.
