CHARACTERIZATION OF CHITOSAN EXTRACTED FROM DIFFERENT ROMANIAN BLACK SEA CRUSTACEANS

Chitosan from different types of crabs collected from the Romanian Black Sea Coast was extracted and characterized. The obtained chitosan powders were analysed and compared in terms of ash content, hygroscopicity and infrared spectroscopy. The purpose of this study is to evaluate which species are more suitable to extract a chitosan with good qualities. The obtained results showed that the marine source influences the chitosan properties. The extracted chitosan can find various uses in different industrial applications.
