Melamine is commonly used in the form of white powder. It is an essential intermediate product of the organic chemical industry. When it is over 99.8%, it can be dissolved in methanol, formaldehyde, acetic acid, glycerin, etc. If consumed for a long time, it will cause damage to the reproductive and urinary system, and bladder and kidney stones can further induce bladder cancer. It belongs as an industrial raw material and an essential organic chemical product. It is also a slightly toxic substance soluble in water and is not allowed to be added to food.
In the test in 2008, the highest melamine content in Sanlu brand infant formula milk powder was 2563 mg/kg, and this chemical raw material that can not appear in food is the culprit causing infants to suffer from kidney and urinary system stones.
So, what exactly is melamine? English melamine, the molecular formula is C3H6N6, also known as, 2,4,6-tri amino-1,3,5-triazine. The appearance and physical properties of melamine are pure white monoclinic prism crystal, white and tasteless, which is similar to the appearance of protein powder. Melting point 345 Degrees (decomposition), density 1.573 grams / cubic meter (16 degrees). Slightly soluble in water and ethanol, and can form salts with sulfuric acid, nitric acid, acetic acid, oxalic acid, etc.
In neutral or slightly alkaline conditions, It is condensed with formaldehyde to form various hydroxymethyl melamine. Still, in slightly acidic conditions (pH value 5.5-6.5), it is polycondensation with methyl derivatives to create green resin products. When it is hydrolyzed in a strongly alkaline aqueous solution, the amine group is gradually replaced by the hydroxyl group to form cyanuric acid diamide, further hydrolyzed to form cyanuric acid monoamide, and finally forms it.
this is only a pure chemical substance and raw material which has nothing to do with food. Therefore, if people eat by mistake, their health will be significantly damaged.
it can cause not only kidney stones but also to have a severe impact on human health. The main symptoms of kidney stones are pain and hematuria. The pain can be dull pain or severe colic. Symptoms depend heavily on the size and location of the rock, the degree of obstruction and infection. A few stones without obstruction or mild obstruction without disease are primarily asymptomatic and have caused renal function damage without feeling. It was found only when doing B-ultrasound, abdominal X-ray or CT examination. The harm of stones to the kidney mainly lies in blocking the urethra and directly damaging the urethral mucosa, resulting in renal dysfunction.
Melamine has caused many children to suffer from major diseases and brought incurable wounds to many families in our country. Children are the future flowers of the motherland. We are unwilling to bring this disaster to others. Therefore, melamine is firmly not allowed to be used in any food substances.
