The minimum information needed to validate many published simulations would be the spatial Swelling quantiﬁcation of the solute material with time. In this study we develop a simple methodology to quantify the Protein quantiﬁcation protein content in heat induced protein hydrogels using a commercial Coherent anti-Stokes Raman Spectroscopy CARS (CARS) microscope. The system is used to quantify the whey protein isolate (WPI) concentration in hydrogels Microscopy undergoing dissolution at alkaline pH. Quantitative measurements were performed in hydrogels up to depths of ∼600 µm, with an average accuracy of ∼1 wt%. Results show that the protein concentration within the swollen layer is constant with time, conﬁrming the existence of steady state conditions during dissolution.
