Abstract

Arabian deep-sea red shrimp Aristeus alcocki is considered to be an ideal source of pigments, especially astaxanthin, and its analogs. Extraction of pigments from exoskeleton discards of A. alcocki was analyzed by using organic solvents, namely, n-hexane, acetone, ethyl acetate, methanol, and ethanol under cold and hot conditions. A significantly greater pigments yield was obtained using acetone: methanol (1:1 v/v) (10.4-10.9%) and ethanol (9.3-9.7%) extractions compared with conventional acetone extract (7.4-8.1%) (p < 0.05). Chromatographic experiments with the pigment extracts showed the presence of free astaxanthin, astaxanthin mono-ester, and astaxanthin di-ester.
