Figure 2. — (A) Comparison of DSC thermograms of pristine apigenin (AP), lyophilized WPI after the pH-cycle treatment (pH-treated WPI), and lyophilized powder of the nanodispersion prepared with 10.0 mg/mL WPI and 2.0 mg/mL AP using the pH-cycle (nanocapsules); (B) XRD patterns and (C) FTIR spectra of (a) pristine AP, (b) unprocessed WPI, (c) pH-treated WPI, (d) the nanocapsules, and (e) a physical mixture of pristine apigenin and unprocessed WPI.
