Summary

Starch is either used as extracted from the plant and is called “native starch,” or it undergoes one or more chemical modifications to reach specific properties and is called “modified starch.” The preparation of starch nanocrystals (SNCs) is based on native starches. Starch nanoparticles (SNPs) can schematically be divided into two kinds: (i) those exploiting the semicrystalline property of starch, such as SNC; and (ii) those exploiting the gelatinizing/melting property of starch referred to as colloidal or regenerated SNP (rSNP). They can further be categorized by their production process. SNCs are mainly prepared by hydrolysis, while SNPs are prepared by “regeneration” (chemical treatment or solubilization/precipitation) or mechanical treatment. Current applications for SNC and rSNPs are mainly focused on nanocomposites or paper coating, showing the importance of the thermal stability of these nanoparticles.
