Zein CAS 9010-66-6 Corn Alcohol

As an industrial polymer, zein alcohol has received extensive attention and has been used in drug delivery systems, such as microsphere structures and membrane structures, for the delivery of anticancer drugs, anticoagulants, and parasites. showed better compatibility. During the dissolution process of the tablet, zein forms a gel-like coating and a network structure to prevent the tablet from breaking. As the coating of the tablet, zein is compact and brittle, and the solvent penetrates into the drug to dissolve the drug. Through the formation of zein The porous structure of the osmotic system slowly releases the drug.

Zein alcohol nanoparticles can protect therapeutic proteins and enable catalase and superoxide dismutase to fully exert their drug effects. Folate-catalase or superoxide dismutase can scavenge reactive oxygen species produced by macrophages in vitro under the protection of zein alcohol nanoparticles. As a substitute for pharmaceutical film-forming agents such as cellulose or polyacrylate derivatives, zein films have been made into microspheres for transporting insulin, heparin, ivermectin, and lactobacillus. The zein granules protect most of the lycopene from being released in the stomach.

Due to the existence of environmental problems, the development of edible and degradable packaging materials from natural polymers is an important research object at present. Using phenolic compounds such as catechin, gallic acid, p-hydroxybenzoic acid, and ferulic acid to change the fragility of zein film, a zein film with antibacterial and antioxidant properties can be used as a bioactive packaging material. Differential scanning calorimetry and Fourier transform infrared spectroscopy showed that the electrospinning of zeanol containing phase change materials could be used as an effective packaging material.

The surface area of zein electrospun fibers is huge, and the positioning of gallic acid on the surface allows zein to be used as an edible coating for dry food, or as a part of a multilayer structure, and has certain antibacterial properties. Biomaterials hold great promise in the food industry. An ultrafine zein polymer fiber was developed by electrospinning technology, which can be used as edible antibacterial food packaging. Confocal Raman imaging spectroscopy was used to find that β-carotene was distributed in a uniform state in the fiber , so that beta-carotene can be extracted from this fiber, and at the same time the packaging has strong antioxidant properties even under UV rays. Adding antibacterial substances to packaging materials can prolong the shelf life of food, and the combination of zein alcohol and active compounds, thymol, and natural fibers is of great significance for the development of new packaging materials.

In recent years, the demand for plastic packaging has been increasing. Based on environmental considerations, the development of degradable film packaging is of great significance to the ecological environment. Edible and biodegradable films and coatings can not only control the transmission of moisture, oxygen, and carbon dioxide , retain flavor components, prevent quality deterioration and increase shelf life of food. The interaction between zein alcohol and polysaccharides, lipids and other proteins can change its functionality. Both whey protein and zein alcohol, which are industrial by-products, have good film-forming properties. Using whey protein and zein alcohol to make a single-layer film and Laminated film, compared with pure whey protein film, the ultimate tensile strength of the film is increased, and the hydrophobicity is enhanced.

The zein film containing lysozyme can inhibit the production of Listeria monocytogenes in cheese at 4 ℃, the zein film containing gallic acid and catechin can make the cheese have a certain antioxidant activity, and the corn with natural antibacterial compounds Protein film active packaging can not only increase the safety of fresh cheese, but also improve the quality of cheese.

Lysozyme is one of the most commonly used antibacterial substances, and it often appears in paper packaging materials. The distribution and release of lysozyme can be controlled by using corn alcohol. Lysozyme, albumin, and disodium EDTA are added to corn alcohol to develop a A functional food with antibacterial, antioxidant and free radical scavenging properties, in which albumin can change the distribution of purified lysozyme in the protein film, and at the same time reduce the solubility of lysozyme in the film in distilled water. The surface of zein alcohol is hydrophobic, and it can be used as an oil analogue to replace part of the cream in ice cream and salad oil to make mayonnaise. Compared with ordinary oil, it contains less calories and can effectively prevent obesity caused by high-calorie diets. High blood pressure and diabetes, in line with the requirements of a healthy diet.
