NAVIA, DIANA PAOLA; VILLADA, HÉCTOR SAMUEL  e  TORRES, GERARDO ANDRÉS. FLOUR MORPHOLOGICAL CHARACTERIZATION OF SEVEN CASSAVA VARIETIES AND FIQUE DUST BY HIGH RESOLUTION LIGHT MICROSCOPY-HRLM-. Rev.Bio.Agro [online]. 2010, vol.8, n.2, pp.79-85. ISSN 1692-3561.

Morphological characteristics of seven varieties of native cassava flour and fique dust were evaluated. The samples were dispersed in egg albumen, then spread on glass plates and stained with toluidine blue for observation under the microscope. High Resolution Light Microscopy technique (HRLM) was used, with differential interference contrast (DIC) to observe the samples and characterize the image. Spherical and hemispherical starch granules, truncated and some with fibrous structures in different ways, were found in flour. In fique dust longitudinal microfibrils were observed in the form of tapes, cells and spirals. This study allowed to characteríze the morphology of the raw materials studied, whose information is the starting point for its continued use in the field of biodegradable materials.
