Characterization of the main sources of chitin in cuba

Abstract

The chemical composition and thermal behaviour of crab, shrimp and lobster shells were studied. The lobster cephalothorax and its main parts also constitute important sources of both polymers. Their chitin and protein content are 20 and 40 %, respectively (dry base) while in these cases the proteins are less associated to the matrix than in the carapace. The chitin level in the chitinous concentrates isolated from different sources is over 80 % in all cases but the polymer characteristics change in dependence on the raw material.

Zusammenfassung

Es wurde die chemische Zusammensetzung und das thermische Verhalten von Krabben-, Garnelen- und Hummerpanzern untersucht. Der Hummer cephalothorax und auch seine Hauptteile bilden wichtige Quellen für beide Polymere. Der Chitin- und Proteingehalt beträgt 20 bzw. 40% (bezogen auf Trockensubstanz), während in diesem Falle die Proteine weniger an der Matrix assoziiert sind als im Panzer. Der Chitingehalt in aus verschiedenen Quellen gewonnenen Chitinauszügen liegt in allen Fällen über 80%, die Eigenschaften der Polymere schwanken jedoch in Abhängigkeit vom Ausgangsmaterial.
