Chemical Properties Zein is a prolamin obtained from corn (Zea mays Linne' (Fam. Gramineae)). It occurs as a granular, straw- to pale yellow-colored amorphous powder or fine flakes and has a characteristic odor and bland taste.
Uses Paper coating, grease-resistant coating, label varnishes, laminated board, solid-color prints, printing inks, food coatings, microencapsulation, fibers.
Uses Zein is a corn protein produced from corn gluten meal. it lacks the amino acids, lysine and tryptophan, so it is not suitable as a sole source of dietary protein. it is insoluble in water and alcohols but is soluble in aqueous alcohols, glycols, and glycol ethers. it functions as a film and coating to provide a moisture barrier for nuts and grain products. it also functions as a coating for confections and a glaze for panned goods.
Production Methods Zein is extracted from corn gluten meal with dilute propan-2-ol.
Pharmaceutical Applications Zein is used as a tablet binder in wet-granulation processes or as a tablet-coating agent mainly as a replacement for shellac. It is used primarily as an enteric-coating agent or in extended-release oral tablet formulations and other delivery systems. Zein is also used in food applications as a coating agent.
Safety Profile When heated to decomposition it emits acrid smoke and irritating fumes.
Safety Zein is used in oral pharmaceutical formulations and food products, and is generally regarded as an essentially nontoxic and nonirritant material at the levels employed as an excipient. However, it may be harmful if ingested in large quantities.
storage Zein should be stored in an airtight container, in a cool, dry place. It has not been reported to polymerize.
Incompatibilities Incompatible with oxidizing agents.
Regulatory Status GRAS listed. Included in the FDA Inactive Ingredients Database (oral tablets). Included in nonparenteral medicines licensed in the UK. Included in the Canadian List of Acceptable Non-medicinal Ingredients.
