Structural parameters of amylopectin clusters and semi-crystalline growth rings in wheat starches with different amylose content

SAXS and SEM were used to investigate the internal structure of granules from wheat starches with differing amylose content. Small-angle X-ray scattering (SAXS) and scanning electron microscopy (SEM) were used to investigate the internal structure of wheat starch granules with different amylose cont...

Description
Summary:SAXS and SEM were used to investigate the internal structure of granules from wheat starches with differing amylose content. Small-angle X-ray scattering (SAXS) and scanning electron microscopy (SEM) were used to investigate the internal structure of wheat starch granules with different amylose content. Different approaches were used for treatment (interpretation) of SAXS data to assess the values of structural parameters of amylopectin clusters and the size of crystalline and amorphous lamella in different wheat starches. The average values of the semi-crystalline growth rings thickness in starches have been determined and the relationship between structural characteristics and thermodynamic melting parameters is discussed.
