Commercial Spirulina powder differs in the carotenoid composition from preparation to prepazation. In order to elucidate the reason we analyzed carotenoids in Spirulina maxima spray-dried at 80°C(Sml) and 200°C (SmII). The contents of carotenoids in SmI and SmII were 648 and 6.0 mg/100g, respectively. The main components identified in SmI were zeaxanthin (25%), myxoxanthophyll (13-17%), β-carotene (15%), . and echinenone (11-13%), and a rare carotenoid, 3'-hydroxyechinenone, was also detected at 7-11%. In SmII, only two carotenoids, zeaxanthinand β-cryptoxanthin were detected as major components, and presumably decomposed products were observed in appreciable proportions. Thus the marked discrepancies in the composition of carotenoids of dried Spirulina preparations are most probably due to their thermolability.
