Features
- Hydrophobic and Amphiphilic: Exhibits distinct hydrophobic and hydrophilic domains, enabling self-assembly into nanoparticles, films, and nanostructures in solvents like ethanol.
- Solubility Profile: Insoluble in water but highly soluble in 70-90% aqueous alcohol solutions, with low solubility in neutral pH environments.
- Biodegradable and Biocompatible: Naturally breaks down without toxicity, recognized as safe by the FDA for oral and biomedical applications, with low immunogenicity.
- Physical Properties: Appears as a clear, hard, odorless, and tasteless powder or film at room temperature, with a high α-helical secondary structure.
- Thermal Stability: Resistant to moderate heat, suitable for processing into coatings and fibers.
- Amino Acid Composition: High in glutamine (21%), leucine (19%), and proline (9%), but lacks tryptophan and is low in lysine, limiting nutritional value.
Applications
- Food and Packaging: Used as a confectioner’s glaze for coating candies, nuts, fruits, and pills, providing a moisture barrier; also in edible films and bakery coatings.
- Pharmaceuticals and Drug Delivery: Serves as an excipient for controlled-release matrices, nanoparticles for encapsulating drugs, and protective coatings for tablets due to its biocompatibility.
- Biomedical and Tissue Engineering: Employed in scaffolds for tissue regeneration, wound dressings, and as a carrier for bioactive compounds like anticancer peptides.
- Industrial Coatings and Adhesives: Applied in paper coatings for cups, bottle cap linings, inks, and water-resistant barriers; also as a shellac substitute in varnishes.
- Textiles and Plastics: Incorporated into biodegradable fibers, plastics, buttons, and laminated boards as a renewable alternative to synthetic polymers.
- Cosmetics and Other: Utilized in chewing gum bases, cosmetics, and as a binder in solid color printing films.
