Description

Zein CAS NO 9010-66-6 is a natural, biodegradable protein derived from corn (maize), specifically the prolamin fraction of corn gluten. This unique biopolymer is valued for its excellent film-forming, binding, and coating properties, offering a sustainable alternative to synthetic materials. It is essential for manufacturers in the food, pharmaceutical, and specialty chemical industries seeking natural, functional ingredients for encapsulation, edible films, and controlled-release applications.

Application

• Edible Films & Coatings: Used to create water-resistant, glossy coatings for nuts, confectionery, and pharmaceutical tablets to improve shelf life and appearance.
• Microencapsulation: Acts as a natural wall material for encapsulating flavors, colors, vitamins, and active pharmaceutical ingredients (APIs) for controlled release and protection.
• Food Texture & Adhesion: Functions as a binder and texturizer in processed foods, cereal coatings, and seasoning blends.
• Biodegradable Packaging: A key component in the development of compostable films and packaging materials as part of bio-based polymer blends.
• Pharmaceutical & Nutraceutical Tableting: Serves as a sustained-release agent and binder in tablet formulations.
• Personal Care & Cosmetics: Utilized in hair sprays, nail polish, and other cosmetic products for its film-forming and fixative properties.
• Adhesives & Inks: Employed in specialty industrial applications, including remoistenable adhesives and printing inks.
