Karakteristik glukosamin hidroklorida (HCl GlcN) dari kitin dan kepiting Chitosan Biru Kolam (Portunus pelagicus)
ABSTRACT: Shell of blue
swimming crabs is an potential source of glucosamine as their producttion is
abundant and not yet economically utilized. In tis study glucosamin was
extracted from chitin and chitosan of blue swimming crabs shells by HCl of
various concentrations (33%, 35%, 37%), and the products obtained were
evaluated for rendement, quality characteristics. The results indicated that
the highest glucosamine rendement was obtained from chitin extracted with 33%
HCl, but the best purity, Lod and melting point was produced from chitosan
extracted by 35% HCl. Compared to standar, glucosamin purity, Lod and melting
point extracted from t kitosan was slightly lower. The purity, moisture, Lod
and melting point of glucosamin extracted from chitosan of blue swimming crabs
shell as well as standart was 65,543%; 5,208%, 0,856%; 186°C; and 95%; 5,194%;
0,767; 190°C respectively.
