ABSTRACT: Channel catfish muscle was subjected to 2 novel protein extraction and precipitation techniques using acid (pH 2.5) or alkaline 11) pH compared with surimi processing (3 wash cycles). Solubility of proteins found be highest at 2.5 11, these levels, viscosity low enough cause separation from insoluble materials via centrifugation. Both the acid-aided alkali-aided processes led higher recoveries (P < 0.05) larger reduction in lipids processing. The recovery could increased even more...
