  • Recovery of compounds using a natural adsorbent
    Patent number: 7052721
    Abstract: The invention provides a method for recovery of compounds by adsorption fish scales. The method can be used for natural and synthetic compounds such as various natural pigments including astaxanthin in an esterified or not and synthetic astaxanthin in free form, or other carotenoid compounds. Fish scales with an adsorbed compound may be used as a source of the compound both for human and animal consumption. In particular, fish scales with adsorbed astaxanthin provide a calcium-rich nutritional supplement with beneficial anti-oxidant properties.
