Development and characterization of starch nanoparticles by gamma radiation: Potential application as starch matrix filler

•Gamma radiation is an effective technique for obtain starch nanoparticles (SNP).•Nanoparticles of 20 and 30nm can be obtain from cassava and waxy starch, respectively.•Addition of 2.5wt.% waxy SNP leads to increases of 102% in cassava storage modulus. Gamma radiation arises as an advantageous alter...
