Recently it was found that an organic compound melamine which consists of about 66% nitrogen by mass has been added to the milk products (milk, baby milk, baby milk mixtures, yogurts, etc) of certain unfair manufacturers. Seemingly it was done to artificially inflate the readings of protein level. Added in significant amounts melamine was appeared to be toxic, especially for babies, and caused acute kidney failure with several fatalities. Several thousands of babies in China are now seriously ill. Milk products, contaminated with melamine were also found on the markets of Singapore, New Zeeland and in S. Korea. To provide an express analysis of this contaminant, LUMEX has recently developed a method of melamine determination in milk and milk products by capillary zone electrophoresis on CAPEL®-105/105M instrument. |
