In reference to granules fragmentation, previous works have revealed that at sufficiently long amylolysis periods some gran-ules became split open revealing their internal layered structure(Li, Vasanthan, & Bressler, 2012; Miao et al., 2011). Kim et al.(2008), hypothesized that the erosion of the amorphous regions of the granules induced their fragmentation. With the increase of hydrolysis time, the fraction of fragmented particles here in observed increased, exposing the interior of a higher fraction of granules with the described hydrolyzed/non-hydrolyzed layered pattern (Fig. 2(g)). Granules fragmentation was also evidenced by the progressive reduction of the average granules diameter. Size distributions found in this contribution for increasing hydrolysis time showed average diameters that reduced from 11 m to 7.7 min 24 h of hydrolysis. At reaction times higher than 48 h, SEM images suggested partial gelatinization of starch which is illustrated by partially hydrolyzed starch granules which appeared “covered” by an amorphous gel (Fig. 2(h)). Partial gelatinization could have been caused by extensive shear during long periods with magnetic stir-ring.
