Isoelectric solubilization/precipitation (ISP) at acidic and basic pH was applied to whole carp, yielding proteins, lipids, insolubles. The objective characterize composition of recovered materials. Crude protein concentrated 89-90% in proteins 94-95% pH. Basic yielded with more (P < 0.05) essential amino acids (EAAs). EAA content met FAO/WHO/UNO requirements. ISP did not affect fatty acid (FA) composition. Lipids contained 88-89% total fat pH, 94-97%. Total low, EPA DHA the highest percentage for 11.5. ISP, particularly effectively removed impurities such as bones scales from carp. This is indicated by 3.8-5.8% ash compared 11.2% carp 5.4% boneless/skinless fillets. less Ca, P, Mg proteins.
