Zein, identified by the CAS number 9010-66-6, is a prolamine protein derived from corn. It is a yellowish - white to brownish - yellow powder with a faint odor. Zein is insoluble in water but soluble in aqueous alcohol solutions. Its molecular weight typically ranges from 20,000 to 45,000 Daltons, which gives it unique physical and chemical properties.
The purity of our factory - supplied zein is high, meeting strict quality control standards. The moisture content is usually less than 8%, ensuring its stability during storage. It has excellent film - forming properties, which make it suitable for a variety of applications.
1. **Food Industry**: Zein is widely used as a coating material for food products. It can be applied to nuts, candies, and pills to protect them from moisture, oxidation, and physical damage. Additionally, it can be used as a fat replacer in some low - fat food products, improving the texture and mouthfeel.
2. **Pharmaceutical Industry**: In the pharmaceutical field, zein can be used to prepare controlled - release drug delivery systems. Its biocompatibility and slow - release properties make it an ideal material for ensuring the sustained release of drugs in the body, enhancing the therapeutic effect and reducing side effects.
3. **Cosmetics Industry**: Zein is used in cosmetics as a film - forming agent. It can be added to hairsprays, nail polishes, and skin creams to improve the adhesion and durability of the product on the surface of the skin or hair.
For using zein as a coating material in the food industry, first, prepare a zein solution by dissolving zein in an appropriate aqueous alcohol solution (usually 70 - 95% ethanol). The concentration of the solution depends on the specific application requirements, typically ranging from 5% to 20%. Then, use a spraying or dipping method to apply the solution to the food products. After application, allow the coated products to dry at room temperature or under mild heating conditions.
In the pharmaceutical industry, when preparing controlled - release drug delivery systems, zein can be mixed with drugs and other excipients. The mixture can be processed into microspheres, tablets, or capsules using various techniques such as spray - drying, extrusion, or compression.
In the cosmetics industry, zein can be added directly to the formulation during the manufacturing process. Stir the mixture well to ensure uniform dispersion of zein in the cosmetic product.
**Food Industry Case**: A nut company used our zein as a coating material for its almonds. Before using zein, the almonds were prone to rancidity and had a short shelf - life. After coating the almonds with a 10% zein solution dissolved in 80% ethanol, the almonds showed a significant improvement in shelf - life. The zein coating effectively prevented moisture and oxygen from entering the almonds, reducing the oxidation rate of the nuts. As a result, the company was able to extend the product's shelf - life from 3 months to 6 months, leading to a reduction in product waste and an increase in customer satisfaction.
**Pharmaceutical Industry Case**: A pharmaceutical company developed a new controlled - release tablet using zein for a pain - relieving drug. By encapsulating the drug in a zein matrix, the drug was released slowly in the body over a period of 12 hours. This compared favorably to the traditional immediate - release tablets, which required multiple doses per day. The new controlled - release formulation reduced the frequency of dosing, improved patient compliance, and enhanced the overall therapeutic effect of the drug.
