Chitin distribution (1) arthropod mainly crustaceans, such as shrimp, crab, etc., contain chitin up to 58% to 85%; followed Insecta (such as locusts, butterflies, mosquitoes, flies, silkworm pupae containing shells and other crustaceans Su 20% to 60%), Myriapoda (such as millipedes, centipedes, etc.), arachnids (such as spiders, scorpions, ticks, mites, chitin content of 4% to 22%); (2) the main molluscs including dual nerve classes (such as chitons), gastropods (such as abalone, snails), Tusk shell (eg angle shellfish), Lamellibranchia (such as oysters), cephalopods (such as squid, parrot) and other chitin chitin content of 3% to 26%; (3) including the original ring worm annelid classes (such as insect nest angle), hairy feet Gang (such as Nereis, earthworms) and Hirudinea (such as leeches) three bonds chitin market, some with little chitin, while others are as high as 20% to 38%; the role of chitin in the indoor air governance extracted substances in shellfish chitin polymer chitin pictures of natural materials, chitin rich in amino rich, but there will only be after deacetylation presented. Concentration deacetylation through healthy nest after deacetylation unique process, the decomposition of organic amino showing adsorption of harmful gases powerful role.
