Biophysical characterization of α-glucan nanoparticles encapsulating feruloylated soy glycerides (FSG)

•Alpha-glucan polysaccharides encapsulates feruloyl soy glycerides (FSG) to form novel nanoparticles via high-pressure homogenization.•Alpha-glucan-FSG nanoparticles are 1.7- and 1.1-times larger than alpha-glucan nanoparticles and FSG nanoparticles, respectively.•Thermal analysis demonstrates that alpha-glucan-FSG nanoparticles are stable up to about 66 °C.
