Insects have large numbers of individuals, short generations, good breeding ability, and short breeding periods. Because of small body size, it is not necessary to take much of the space and labor for breeding. Therefore environmentally friendly cultivation and mass production are possible. Insects can synthesize and decompose chitin continuously during the life cycle. Because insects have low level of inorganic materials, the acidic treatment used for extracting procedure from insects are moderate in general. Instead of cultivated insect, even insects which can be harmful in agriculture and traffic in urban life might be utilized as an alternative chitin source for application of valuable scope. All insect-derived chitin studied was the most stable structure, α-chitin, and the characteristics related to solubility, molecular weight, degree of deacetylation, ash content, and moisture content were more suitable for various application. Insect-derived chitosan showed high antibacterial, antioxidant and antitumor activities and exhibited biological properties such as the effect of accelerating wound healing and inhibiting the growth of fungi. Therefore, this review article intends to suggest the possibility that insect - derived polysaccharides can be used as a valuable natural resource to replace chitin and chitosan derived from crustaceans.
