MEDINA, Jorge Alberto  and  SALAS, Juan Camilo. Morphological Characterization of Native Starch Granule: Appearance, Shape, Size and its Distribution. rev.ing. [online]. 2008, n.27, pp.56-62. ISSN 0121-4993.

Size and nature of native starch granules influence in its processability as thermoplastic. These characteristics depend upon culture practices and world location. Through light microscopy, the native national corn, cassava and potato starch granule was morphologically characterized. There were significant differences in size, shape and surface. It was concluded that hilum is preferentially located in the center of granule for first and second sources. In the third is located eccentrically. The corn starch median granular size was in agreement with other authors; in potato, it differs. Size distribution in cassava and corn agree with previous experiences.
