Abstract
In this study, freshwater crab (Potamon
potamios, Olivier 1804), economically unevaluated, was used to obtain
chitin-chitosan. Chitin-chitosan was extracted with standardized modified
chemical method. Chitosan was extracted with demineralization, deproteinization,
decoloration (chitin) and deacetylation (chitosan). Grinded shell was obtained
as 60% after boiling, drying and grinding processes. Chitosan yield of crab
shell was determined as 4.65% from grinded crab shell after demineralization
(yield is 34.32%), deproteinization (yield is 7.25%), decoloration (yield is
6.83%) and deacetylation processes. Moreover, freshwater crab stock was
estimated with catch per unit effort (CPUE) data in
Eğirdir Lake for calculation of quantity of
chitosan. Population size was estimated between 12.85±11.88 and 23.86±25.39
tones and freshwater crab was determined as an appropriate crustacean to obtain
chitin-chitosan.
