Rigaku application note
SCOPE
The measurement of iron in milk powder is demonstrated. The analysis is also used for measuring iron in similar food products such as cocoa powder and flour.
BACKGROUND
Milk is dried by evaporation to form powdered milk as way to preserve the milk, giving it a much longer shelf life without the need for refrigeration. Nutrients may be controlled or added at specific levels, the most important being iron. In the production of powdered milk the iron content is very important and monitored throughout the process to
ensure proper iron content of final product. The measurement is also applicable to other similar food powders such as cocoa powder and flour. Monitoring iron can also be important to ensure no excessive contamination from the milling process. To meet these industry needs the Rigaku NEX QC+ offers technicians a fast and simple means of monitoring the iron composition of milk powder, cocoa powder and flour, and is a tool that can be used for quality hecks throughout the entire production process.
