Zein, the major prolamin in Corn, is the perfect coating agent by its excellent film-forming capability, low hydrophilicity and high oxygen barrier property. Zein is presently used in foods and pharmaceutical ingredients for quality preservation, fresh-keeping and glazing.

Historically, zein has been used in the manufacture of a wide variety of commercial products, including coatings for paper cups, soda bottle cap linings, clothing fabric, ^{[ 4 ]}   buttons, adhesives, coatings and binders. The dominant historical use of zein was in the textile fibers market where it was produced under the name "Vicara". ^{[ 2 ] [ 5 ]}   With the development of synthetic alternatives, the use of zein in this market eventually disappeared. By usingelectrospinning, zein fibers have again been produced in the lab, where additional research will be performed to re-enter the fiber market. ^{[ 6 ] [ 7 ]}

Zein's properties make it valuable in processed foods and pharmaceuticals, in competition with insect   shellac. It is now used as a coating for candy, nuts, fruit, pills, and other encapsulated foods and drugs. In the United States, it may be labeled as "confectioner's glaze" (which may also refer to shellac-based glazes) and used as a coating on bakery products ^{[ 8 ]}   or as "vegetable protein." It is classified as Generally Recognized as Safe (GRAS) by the U.S. Food and Drug Administration.

Zein can be further processed into   resins   and other bioplastic   polymers, which can be extruded or rolled into a variety of plastic products. ^{[ 9 ] [ 10 ]}   With increasing environmental concerns about synthetic coatings (such as   PFOA) and the current higher prices of hydrocarbon-based petrochemicals, there is increased focus on zein as a raw material for a variety of nontoxic and renewable polymer applications, particularly in the paper industry. ^{[ 11 ] [ 12 ]}   Other reasons for a renewed interest in zein include concern about the landfill costs of plastics, and consumer interest in natural substances. There are also a number of potential new food industry applications.
