Zein-based nanoparticles for drug delivery applications
Zein’s protein origin and hydrophobicity has raised concerns about its potential use as a delivery system in humans. To overcome this issue, it has been hypothesised that conjugating zein with polyethylene glycol (PEG) could provide steric shielding to the delivery system, thus preventing its …

Zein films as substrates for cell attachment
… high glutamine content. A main example is corn zein. Zein has been reported to support cell attachment. The main hypothesis in this work was that zein is able to support attachment of cancer (HeLa) cells. In this work, HeLa cells were grown on glass slides coated with zein films. It was reported …

Purification of Zein and Xanthophylls From Corn by Process Chromatography
"A preliminary process design and economic analysis of the process suggested good economic returns by combining SEC and AC. About 80% of the capital cost and 85% of the operating cost of the process, as it stands now, is due only to the stationary phase. Our studies on the characteristics of the …

Preparation of Zein-Based Biodegradable Materials and Investigation of Their Physical Properties
Plasticization was improved by dissolving zein and fatty acids in warm aqueous alcohol solutions. Resins were obtained through precipitation and kneading treatments. Inclusion of palmitic and stearic acid in the formulation resulted in harder resins that were suited for rolling into sheets; whereas …
