Zein (also known as maize alcohol-soluble protein or maize gluten) is an alcohol-soluble gluten extracted from maize endosperm and constitutes the primary protein component of maize protein powder. Its molecular structure is rich in non-polar amino acids (glutamine, leucine, proline, alanine, etc.) and lacks basic and acidic amino acids, which gives it unique alcohol-solubility, hydrophobicity and film-forming properties.
