NANOPARTICULES DE GLYCOGÈNE ET DE PHYTOGLYCOGÈNE MONODISPERSÉES ET UTILISATION DE CES NANOPARTICULES EN TANT QU'ADDITIFS DANS DES PRODUITS COSMÉTIQUES, PHARMACEUTIQUES ET ALIMENTAIRES
A composition of phytoglycogen nanoparticles purified from a phytoglycogen-containing plant material is provided. The composition of phytoglycogen nanoparticles is monodisperse. A method of isolating the composition from phytoglycogen-containing plant materials is provided that includes steps of microfiltration and ultrafiltration, but avoids the use of chemical, enzymatic or thermo treatments that degrade the phytoglycogen material.
