The accurate measurement of milk protein is an important part of the dairy industry. Traditionally this has been achieved using wet chemistry analytical techniques such as Kjeldahl. This method remains the most accurate but can take hours thus not suitable for today’s high volume, high speed processing requirements. Current spectroscopic instruments can provide accurate data in minutes (laboratory benchtop) or seconds (inline process).
There has been extensive study into the spectroscopic analysis of dairy products but not for inline applications where the process conditions (temperature, pressure, turbidity) are always fluctuating.
The goal of this research is to better understand the effect of temperature on spectroscopic analysis. This can then be applied to a control system to compensate for those effects.
