Principle of Starch Particle Size Distribution Determination
The determination of starch particle size distribution is based on the interaction between particles and light or fluid motion and can be achieved through the following methods:
1. Laser Diffraction
A laser beam passes through dispersed starch particles, and the scattering angle of the light is inversely proportional to particle diameter. By analyzing the intensity distribution of the scattered light and applying the Mie scattering model, parameters such as D10, D50, D90, and the overall particle size distribution can be calculated.
2. Dynamic Light Scattering (DLS)
This method is based on the Brownian motion of particles in solution. By detecting temporal fluctuations in scattered light intensity, the diffusion coefficient is calculated and converted into particle size using the Stokes–Einstein equation. It is suitable for measuring nanoscale starch particles.
3. Microscopic Image Analysis
Using optical or scanning electron microscopy (SEM), starch particle morphology, surface structure, and distribution characteristics are observed. Combined with image analysis, particle morphology and size can be quantitatively evaluated.
MtoZ Biolabs integrates multiple analytical methods to ensure accuracy and representativeness of the data.
