Hydrolytic efficiency and isomerization during de-esterification of natural astaxanthin esters by saponification and enzymolysis
Electron. j. biotechnol; 34 (), 2018
Background: Astaxanthin from natural sources is typically esterified with fatty acids; hence, it must be hydrolyzed to remove esters before identification and quantification by conventional HPLC. Alkaline-catalyzed saponification and enzyme-catalyzed enzymolysis are the most commonly used de-esterificati...
