Zeine is a term that refers to a biopolymer derived from zein, a prolamin protein found in corn. It is considered one of the major storage proteins found in corn kernels and is commonly used in various industrial applications. Zeine possesses unique properties, such as its ability to form films and coatings, and has gained attention as an alternative to synthetic polymers.
In terms of its composition, zeine is primarily composed of amino acids, specifically proline, glutamine, and cysteine, which contribute to its distinctive properties. It is insoluble in water, making it suitable for applications where moisture resistance is desired. Additionally, zeine is biodegradable, making it an eco-friendly option compared to petroleum-based polymers.
One of the main applications of zeine is as a coating material for food and pharmaceutical products. Its ability to form thin films on surfaces provides a protective barrier against moisture, oxygen, and other environmental factors, thus extending the shelf life of the coated products. Zeine coatings are commonly used on candies, pills, and other confectionery or pharmaceutical products.
Furthermore, zeine has also found applications in the fields of adhesives, personal care products, and textiles. Its film-forming and adhesive properties make it suitable for use as a sizing agent in textile processing and as an ingredient in various adhesive formulations. In personal care products, zeine can be used to enhance the texture and stability of formulations, acting as a film-forming agent.
Overall, zeine is a versatile biopolymer derived from corn, possessing unique properties that make it suitable for a range of industrial applications, particularly as a coating material and adhesive.
