Key Points

This research aims to investigate the effects of acid hydrolysis on the properties of corn starch nanoparticles.
Utilized 2.2 N HCl for acid hydrolysis at 35 °C over 120 hours.
Analyzed changes in amylose content, swelling power, solubility, moisture, and protein/fat contents.
Employed FTIR and SEM to assess structural changes and morphological characteristics.
Used DLS to evaluate particle size distribution.
Acid hydrolysis reduced amylose from 14.78% to 13.61% and swelling power from 17.86 to 16.58.
Solubility decreased from 19.95% to 14.69% and moisture content from 10.95% to 8.91%.
Morphological changes included transformation from smooth granules to rough, aggregated particles.
FTIR results indicated increased order without new chemistry, suggesting stronger hydrogen bonding.
