Hydrolytic efficiency and isomerization during de-esterification of natural astaxanthin esters by saponification and enzymolysis

Conclusion Compared with saponification, enzymolysis with cholesterol esterase was recommended as a more accurate method for de-esterification of natural astaxanthin esters for further qualitative and quantitative HPLC analysis.
