  text: Near infrared spectroscopy in combination with a transflection probe was investigated
    as inline measurement in a continuous flash pasteurizer system with a sugar-water
    model solution. Robustness and reproducibility of fluctuations of recorded spectra
    as well as trueness of the chemometric analysis were compared under different
    process parameter settings. Variable parameters were the flow rate (from laminar
    flow at 30 L/h to turbulent flow at 90 L/h), temperature (20 to 100 degrees C)
    and the path length of the transflection probe (2 and 4 mm) while the pressure
    was kept constant at 2.5 bar. Temperature and path length were identified as the
    most affecting parameters, in case of homogenous test medium. In case of particle
    containing systems, the flow rate could have an impact as well. However, the application
    of a PLS model, which includes a broad temperature range, and the correction of
    prediction results by applying a polynomial regression function for prediction
    errors, was able to compensate these effects. Also, a path length of 2 mm leads
    to a higher accuracy. The applied strategy shows that by the identification of
    relevant process parameters and settings as well as the establishment of a compensation
    strategy, near infrared spectroscopy is a powerful process analytical tool for
    continuous flash pasteurization systems.
