Producing High-quality Chitin by Integrity Principle
Chitin is a natural linear polymer polysaccharide consisting of N-acetyl-D-glucosamine linked by a β-1,4-glycosidic bond. It is widely found in Marine Animals such as crustacean shells, arthropods, and mollusks. Chitin is a rich and diverse class of Marine Carbohydrates and it is the second most abundant natural polymer after cellulose.

Results: In the present study, efficient microwave-assisted extraction of chitin derived from Caribena versicolor was used. The researchers further used advanced tools like XRD, ESI-MS, FTIR and Raman spectroscopy, NMR spectroscopy, etc. to identify and characterize the chitin. It was found that the main biomaterial within the stratum corneum is α-chitin. It can be rapidly isolated and extracted from tissues in a short time.

Applications
- Chitin can be used to develop novel bacteriostatic agents. It not only inhibits common pathogenic bacteria, but also Streptococcus haematobium, Salmonella bacteria, Staphylococcus epidermidis, and Bacillus subtilis.
- Chitin helps drive the development of novel drug delivery systems and marine drugs.
- Chitin can be used to prepare sugar-based nanobiofilms.
- Chitin can be used as an ingredient in the development of dietary food formulations.
- Chitin can be added to foods as an additive, such as a tissue builder, thickener, and soybean coagulant.

Frequently Asked Questions
What are the components of DES?
DES is a two- or three-component low fusion mixture of hydrogen bond acceptors (e.g., quaternary ammonium salts) and hydrogen bond donors (e.g., compounds such as amides, carboxylic acids, polyols, etc.) in specific molar ratios and under specific conditions.
What is the difference between the three crystalline structures of chitin?
- α-Chitin: α-Chitin is the most abundant and structurally stable crystalline form in nature, found mainly in crustacean shells, fish, and invertebrates. Its molecular chains are arranged in reverse parallel and its structure is compact, forming a stable crystalline form. α-Chitin has strong intramolecular and intermolecular hydrogen bonds and is not soluble in water, dilute acids, dilute bases, and general organic solvents.
- β-Chitin: β-chitin is less common in nature and is found mainly in the cartilage of squid. β-chitin molecular chains are arranged in parallel, with low interlayer hydrogen bonding and loosely arranged structures.
- γ-Chitin: γ-Chitin consists of three molecular chains, two in the same direction and one in the opposite direction. It is also found mainly in flexible structures.
