Chitin is one of the critical components which are mainly existing in insect exoskeleton, crustacean shells (crab, shrimp and krill) and even fungi cell wall. Researchers in the world have intensively investigated on chitin and chitosan due to its potential value to develop diverse products ranging from biofertilizers for plant growth to therapeutic agents optimized for human and animal health improvement. In case of Korea, it has been reported that chitin and chitosan have been isolated and biochemically characterized from Musca domestica, Periplaneta americana, Gryllus bimaculatus and Tenebrio molitor. In addition, the technology that chitin monomer (N-acetyl-glucosamine) can be generated from mealworm chitin by using chitinase derived from microorganism has been established and thus will be useful for future application in insect industry in Korea. In other countries, various insects including grasshopper, silkworm, fly and beetle have been used as resources for producing chitin. The chitosan obtained after deacetylation of chitin has been tested for biomedical application with therapeutic purposes in other countries. In conclusion, insect-based chitin research and development for producing diverse products will be essential for activating insect industry and its related pet industry in Korea.
