Alpha- and β-chitosan (CS) Maillard reaction products (MRPs) nanoparticles (NPs) were prepared.
Thermal stability and structural properties of α- and β-CS MRPs NPs were analyzed.
Solubility of α- and β-CS MRPs NPs was significantly higher than that of α- and β-CS.
Alpha- and β-CS MRPs and α- and β-CS MRPs NPs all had low toxicology.
