Chromatographic, spectroscopic, and thermal analytical methods were employed to characterize the novel butylglyceryl pectins (P-OX4) obtained, prior to their formulation into nanoparticles via nanoprecipitation.  Nuclear magnetic resonance (NMR) and Fourier transform infrared (FT-IR) spectroscopy confirmed a degree of modification in these materials in the range 10.4-13.6%, and thermal stability studies indicated an increase in both the thermal decomposition onset and glass transition temperature values (compared to those of the original pectin).
