Near infrared Spectroscopy (NIR) is a tool that has been continuously developed and used in PAT for bioprocess monitoring. Therefore, we evaluated the feasibility of using near-infrared spectroscopy (NIR) as an analytical method to monitor in-line process parameters for C. tetani bioprocess monitoring and the Maillard reaction. Critical process parameters were evaluated from C. tetani  bioprocess samples from various fermentations, and multivariate models were created and compared between off-line and in-line measurements. Furthermore, in-line analysis was further tested to evaluate variation in heat-treated media to assess Maillard browning. Therefore, the results of the study help highlight a potential application of using NIR to evaluate critical process parameters involved in the C. tetani  bioprocess and Maillard browning.
