Application

Zein has been used as a biopolymer in electrospinning technique.[1][2] It has also been used to blend starch involved in the manufacture of thermoplastic material.[3]

Biochem/physiol Actions

Zein is used in the manufacture of fiber, adhesive, coating, ceramic, ink, cosmetic, textile, chewing gum and biodegradable plastics.[4] This protein is a biodegradable and sustainable agropolymer. Thus, it is a great potential replacement for traditional oil-based plastics.[1]

General description

Zein is a prolamine and an alcohol soluble protein present in maize endosperm cells.[4][5] Zein is a 20kDa structural protein and is encoded by the gene mapped on the short arm of maize chromosome 7.[5] This protein lacks essential amino acids, such as lysine and tryptophan. Therefore, it has a poor nutritional value.[4]
