Mechano-chemical effects on arachin in the process of high pressure microfluidization (HPM)
were studied. The micro-morphology, subunits, surface hydrophobicity and the thermal stability of homogenized
arachin were analyzed by scanning electron microscopy (SEM), SDS-PAGE, fluorescence spectra
(FLU) and differential scanning calorimetry (DSC). The results showed that the subunits and the molecular
weight of arachin were not affected by HPM. The particle size and the thermal stability of arachin decreased
with the pressure increasing, and the minima were observed at 80 and 120 MPa, respectively. The surface
hydrophobicity of arachin increased with the pressure increasing, and the maximum was observed at 160
MPa. The mechano-chemical effects of HPM can change the micro-morphology and three dimensional
structure of arachin, and decrease the thermal stability of arachin.

Key words: mechano-chemical effect, high pressure microfluidization, arachin, microstructure, thermal stability
