In this study, 2D fluorescence spectroscopy in combination with three different extrinsic fluorescence dyes were evaluated, in order to establish a process control tool which enables real-time product control during USP. Antibiotic residues in animal-derived foods pose risk to human health including chemical poisoning and antimicrobial resistance, and therefore, constant monitoring throughout the food supply chain is important. Here we briefly outline the approach for experiments in the UV. 2015. Two‐dimensional fluorescence spectroscopy is presented as a new method for bioprocess monitoring.
