The aim of present work consists in synthesis of the novel protein-based superabsorbent from<br />
pure ovalbumin (egg white albumin) and zygomycetes proteins. Thereby the chemical<br />
modification of one lysyl residue of AP and IZP with one molecule of EDTAD was investigated.<br />
The result is the integration of three carboxyl groups for each lysyl residue in the protein<br />
molecules which lead to unfolding of polypeptide chains because of electrostatic repulsion force<br />
[15] . The glutaraldehyde (GLA) as a crosslinking agent was added in order to provide protein<br />
superabsorbent hydrogels. As a continuation of our research objectives on AP and IZP<br />
superabsorbents were to improve the rate of swelling and swelling capacity of superabsorbent<br />
hydrogels by optimization amounts of EDTAD and GLA. Moreover the effects of various<br />
conditions such as normal saline, synthetic urine, pH sensitivity and compressive load on the<br />
swelling properties of the AP and IZP superabsorbent hydrogels were investigated in detail.<br />
An additional objective of this work was the attempt to reduce the excessive petroleum resource<br />
consumption and destruction of the environment by synthesis of a biodegradable protein<br />
superabsorbent hydrogel from low cost protein sources, such as animal, plant and fungal proteins<br />
as well as waste protein from food industries. ……………………………………………<br />
