Zein protein (CAS 9010-66-6) stands out as a remarkable biopolymer with diverse industrial applications, particularly in the food and pharmaceutical sectors. As a leading Zein manufacturer, we are dedicated to providing in-depth insights into its chemical and physical properties, enabling formulators and buyers to leverage its full potential. Understanding these characteristics is crucial for effective product development and procurement.

Chemically, Zein is a class of alcohol-soluble proteins, or prolamines, derived from corn. It is notable for its amino acid composition, being rich in proline and glutamate, yet notably lacking tryptophan and lysine, which impacts its nutritional value when considered as a sole protein source. Physically, Zein typically appears as a yellow powder. Its key functional properties include excellent film-forming capabilities, good extensibility, and strong adhesion. Importantly, it exhibits resistance to water, heat, and fat, making it an ideal choice for protective coatings and natural preservatives.

The solubility profile of Zein is also a significant factor. While insoluble in water, it readily dissolves in aqueous alcohol solutions (typically 70%-80% acetone or 80%-92% alcohol) and alkaline solutions with a pH above 11.2. This solubility is instrumental in its application as a coating agent, allowing for controlled application and film formation.

For companies looking to buy Zein protein, sourcing from a reputable Zein manufacturer is essential. Our production processes are optimized to yield Zein with high purity (88%-96% assay) and consistent physical properties. We ensure that our Zein meets stringent quality controls, providing buyers with the reliability needed for sensitive applications like tablet coatings and food preservation.

We encourage R&D scientists and procurement managers to explore the capabilities of Zein protein. Whether you require it for advanced pharmaceutical formulations or innovative food products, partnering with a trusted Zein supplier like ourselves ensures access to premium material and expert support.
