<strong>Abstract</strong><br>
Starch Nanocrystals have excellent properties as compared with native starch. These properties are required in
different applications. In this work, Starch Nanocrystals (SNC) was prepared by acid hydrolysis of native Corn Starch using
1 L of 3.16 M H2SO4 solution and placed at ambient temperature (19-25 oC) for 3 weeks. The FTIR results revealed that of
SNC indicated that there are no significant changes in the results before and after acid hydrolysis due to the stable structure
of the glucose units. The SEM observing of native starch granules showed spherical and oval morphology and the granular
sizes were between 16.04 μm and 4.23 μm. The average size and morphology of SNC were studied using TEM. The
morphology of SNC is polygonal structures and the sizes of SNC are measured with the aid of TEM which its size was 25-
62 nm. It is assumed that acid hydrolysis of native starch will help to produce high performance SNC which can be use as
reinforced in polymer composites for slow release fertilizes and other industrial applications.
