The correct answer is Zein. Zein is a class of prolamin proteins that are mainly present in maize. All the zein polypeptides are products of different structural genes. In general, maize grain is low in protein content (9. 1%), oil (4. 4%), and ash (1. 4%), but very high in starch content (73. 4%) when considered on a dry matter basis. Zein is usually manufactured as a powder from corn gluten meal. Pure zein is clear, odourless, tasteless, hard, water-insoluble, and edible, and it has a variety of industrial and food uses.
