Near-infrared spectroscopy as a process analytical technology tool for monitoring performance of membrane filtration in a whey protein fractionation process. Open
A successful transition from a laboratory proof-of-principle to a functioning industrial Process Analytical Technology (PAT) application of spectroscopy and chemometrics is still an active area of research and development. A comprehensive …

UV spectroscopy as a quantitative monitoring tool in a dairy side-stream fractionation process Open
In this work, we investigate the feasibility of multi-wavelength ultra-violet spectroscopy for the quantification of β-lactoglobulin and α-lactalbumin in ultrafiltration permeates from protein fractionation processes. Spectra from solution…

Cage of covariance in calibration modeling: Regressing multiple and strongly correlated response variables onto a low rank subspace of explanatory variables Open
In analytical chemistry, multivariate calibration is applied when substituting a time-consuming reference measurement (based on e.g. chromatography) with a high-throughput measurement (based on e.g. vibrational spectroscopy). An average er…

Prediction of α-Lactalbumin and β-Lactoglobulin Composition of Aqueous Whey Solutions Using Fourier Transform Mid-Infrared Spectroscopy and Near-Infrared Spectroscopy Open
Characterization and quantification of individual whey proteins are of crucial importance to many industrial dairy processes. Labor intensive wet-chemical methods are still being used for this purpose, but a rapid quantification method for…

Chemical characterization by gas chromatography-mass spectrometry and inductively coupled plasma-optical emission spectroscopy of membrane permeates from an industrial dairy ingredient production used as process water Open
Reusing reverse osmosis (RO) membrane permeate instead of potable water in the dairy industry is a very appealing tactic. However, to ensure safe use, the quality of reclaimed water must be guaranteed. To do this, qualitative and quantitat…
