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.
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
