Basic Studies of Corn Proteins for Improved Solubility and Future Utilization: A Physicochemical Approach
1987
AUGUSTINE, MICHAEL E. | Baianu, Ion C.
Carbon‐13 Nuclear Magnetic Resonance (NMR) spectra were recorded for zein corn proteins in a number of organic solvent systems to establish the best solvent for these highly hydrophobic proteins. Carbon‐13 NMR techniques were used to monitor at the molecular level the mobility of the amino acid side chains in solution. Polyacrylamide gel elcctrophoresis (PAGE). and sodium sodium dodecyl sulfate polyacrylamide gel elcctrophoresis (SDS‐PAGE) was performed to identify the major subfractions in zein and to determine the effect that solvents such as ethanol and 2‐propanol have upon the aggregation of zein proteins. It was determined, based on these studies, that pyridine: watcr (I:I. v/v) provided the best dispersibility for zein and the best subunit separation.
