Advances in zein- based hybrid bio-nanocomposite: a short review
This paper contains synthetic approach and characterization study of bio-hybrid material based on zein. A novel zein is found as a mixture of protein complexes whose molecular size, solubility and charge depend on the corn variety and the separation method used for extraction. Zein is soluble in various primary, binary and ternary solvent systems, mainly determined by the balance between the polar/nonpolar groups in those systems. Because of the large proportion of hydrophobic residues in zein, this protein is not soluble in pure water.
