citric acid 
and 
boric acid 
are not dangerous to use, however they have their 
own drawbacks (Simkovic I, 2009).
In this study, after reducing hydrophilicity and swelling power of TPS by 
applying suitable cross-linking method, a noticeable improvement is 
observed, however, there is still a need to reinforce mechanical characteristics 
of starch using specific additives. Several substances have been analyzed 
and according to these investigations TiO
2
is one of the most efficient fillers. 
Blending TPS with TiO
2
has improved the tensile strength and toughness of 
material obviously. According to a study blending of TPS/TiO
2
with 1% TiO
2
had the best results for advanced mechanical properties. Adding TiO
2
at low 
concentrations (0-3%) has changed the rheological characteristics and 
crystalline behavior (Oleyaei S. A., 2016). As a consequence of this reinfor-
cement operation, the tolerance of TPS has been increased considerably and 
application areas were expanded.
