Description
Chitin is a naturally occurring nitrogen-containing polysaccharide polymer, primarily obtained from the shells of crustaceans such as shrimp and crab, as well as fungal cell walls. As the second most abundant organic polymer on Earth—after cellulose—chitin boasts an estimated annual natural synthesis exceeding one billion tons. With its inherent strength, biocompatibility, and biodegradability, chitin serves as a vital raw material for producing chitosan, glucosamine, and related biopolymers. Our purified technical-grade chitin retains high structural integrity and molecular consistency, making it suitable for research, manufacturing, and a wide range of industrial applications.
