NC-AFM (non contact atomic force microscopy) was used to observe the surface of triticale starch granules. The method allows to obtain micro-images of high resolution with no sample pretreatment. Surface structures and protrusions or pores found on the surface of triticale starch granules had a broad range of diameters. The existence of flat, smooth regions on the starch granules, with no visible structures, pores or protrusions, was confirmed.

nr 4

Absorption, transmission and scattering of visible light by potato starch granules were studied using simultaneously crossed polarised and non- -polarised light or red laser beam microscopy (CLBM). Novel optical phenomena were discovered. In our paper they are called the lens, light guide, internal cross, and hedgehog effects. They contribute to the knowledge about interaction of visible light with internal structure of starch granules. These kind of observation might be useful in estimation of the granular starch quality and influence of physical, chemical, and enzymatic processing on the internal organisation of granules. The method is non-destructive.
