Background:

Traditional starch nanoparticle (StNP) synthesis involves harsh conditions, long processing times, and low yields.
Existing methods often result in uncontrolled particle sizes and limited efficiency.

Purpose of the Study:

To develop a novel, efficient, and eco-friendly technique for synthesizing starch nanoparticles (StNPs).
To investigate the impact of sodium hydroxide, glycerol, and homogenization on starch structure and nanoparticle formation.

Main Methods:

Synthesis of StNPs using a combination of sodium hydroxide and glycerol in an aqueous medium.
Precipitation of StNPs under homogenization at ambient conditions.
Characterization of native starch (NS), StNPs1, and StNPs2 using FTIR, XRD, TGA, and Transmission Electron Microscopy (TEM).

Main Results:

TEM analysis revealed well-defined, uniformly distributed round StNPs (StNPs1) with an average size of approximately 62.5 nm.
Starch nanoparticles synthesized via the second method (StNPs2) exhibited non-specific shapes.
The new technique utilizes eco-friendly chemicals and combines mechanical and chemical processes for ease of use.

Conclusions:

The developed method provides an accessible, environmentally friendly approach for producing starch nanoparticles.
The combination of chemical treatment (NaOH, glycerol) and mechanical processing (homogenization) influences StNP characteristics.
This technique represents a significant improvement over conventional StNP synthesis methods.
