AI Article Synopsis
- Monitoring oil-in-water emulsions using FTIR spectroscopy faces challenges because the technique primarily interacts with the continuous phase, making it hard to analyze the dispersed phase.
- Enzymatic hydrolysis of sunflower oil was conducted within this emulsion, and a new μ-membrane module was used to separate the oil phase for analysis.
- By applying a chemometric model, specifically the partial least squares (PLS) algorithm, the study enabled real-time tracking of free fatty acid concentrations in the separated oil phase through FTIR spectra.
Article Abstract
Monitoring the dispersed phase of an oil-in-water (O-W) emulsion by means of Fourier transform infrared (FTIR) spectroscopy is a challenging task, restricted to the continuous phase that is in contact with the FTIR probe. Nonetheless, real-time measurement and kinetic analysis by FTIR, including analysis of the dispersed, often non-polar phase containing substrates and/or products, is desirable. Enzymatic hydrolysis of sunflower oil was performed in an O-W emulsion. After separation of the oil phase by use of a newly developed μ-membrane module, infrared spectra were collected using an attenuated total reflectance (ATR) cell. Different chemometric models were calibrated using the partial least squares (PLS) algorithm. Online application of a chemometric model based on the FTIR spectra enabled real-time monitoring of free fatty acid concentrations in the oil phase.
