Zein (/ ˈ z iː ɪ n / ZEE-in) is a class of prolamine protein found in maize. It is usually manufactured as a powder from corn gluten meal. Zein is one of the best understood plant proteins. [1] Pure zein is clear, odorless, tasteless, hard, water-insoluble, and edible, and it has a variety of industrial and food uses. [2] [3]

2024年12月1日 · This study explored the rheological and structural properties of the corn prolamin zein under varying temperature and pH conditions and compared its rheological behavior to the barley prolamin hordein. Zein showed plasticization when heated, with plasticization temperatures ranging from 41.3 °C at pH 4 to 46.7 °C at pH 6.

Zein is a natural water-insoluble protein that contains over 50% nonpolar amino acids in its molecular structure. The hydrophobic region of zein can be polymerized into micro-/nanoparticles, making it the most widely utilized protein in Pickering emulsion ( Cui, McClements, et al., 2023 ).

2012年8月31日 · Zein is an alcohol-soluble, naturally occurring protein polymer obtained from corn. It is classified into four classes (α, β, γ and δ) according to solubility and α -zein is the most abundant. The α -zein has large amounts of hydrophobic residues such as leucine, proline, alanine, and phenylalanine that contribute to its hydrophobic properties.

2022年4月16日 · In this study, we employed five methods to extract zein from commercial maize protein powder, analyzing amino acid composition, morphology, molecular weight, zein yield, denaturation rate and solubility.

two maize zein proteins (apparent molecular weights of 19,000 and 22,000), a structural model is proposed for their molecular conformation. The circular dichroic spectrum taken in the 190-240 nm range for a zein protein mixture in methanol solution showed the zein secondary structure to be largely helical. The polar,

2025年2月5日 · Zein (Figure 1), the main prolamin in corn, was first discovered by Gorham in 1821 in the product zea. It was classified by Osborne as a prolamin and shown to be extractable in aqueous alcohol such as ethanol. As production of zein was commercialized in 1939, many potential uses for zein were identified. [1] Composition of Zein

2024年11月15日 · This research article presents a comprehensive investigation into the three-dimensional structure, physicochemical characteristics and conformational stability of the Zein protein. Machine learning (ML) based homology modeling approach, was employed to predict the 3D structure of Zein protein.

2005年12月27日 · SAXS and light-scattering experiments suggest that in alcohol/water mixtures α-zein exists as an oblong structure with an axial ratio of ∼6:1. Furthermore, ultracentifugation, birefringence, dielectric, and viscosity studies indicate that α-zein behaves as an asymmetric particle with an axial ratio of from 7:1 to 28:1.

2021年5月1日 · Zein, a class of alcohol-soluble prolamines in maize endosperm, is mainly composed of α-zein, β-zein, and γ-zein. It has been recognized as a structural protein for various gluten-free systems since it can form gluten-like viscoelastic network.
