Synthetic astaxanthin has better effects than natural astaxanthins on growth performance, body color and n-3 PUFA deposition in black tiger prawn (Penaeus monodon)

Aquaculture Reports, 2023
Astaxanthin is an efficient nutrition strategy to relieve oxidative stress and enhance crustacean body color. Because of technological and economic benefits, synthetic astaxanthin is favored by the aquatic feed industry.

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

Electronic Journal of Biotechnology, 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.

Prediction of Elution Profiles in Countercurrent Chromatography With a Linear Loss of Stationary Phase. [PDF]

J Sep Sci
A common challenge in reliably predicting elution profiles in countercurrent chromatography using the ProMISE2 software is a persistent loss of stationary phase (i.e., bleeding). This drawback can be overcome by a simple calibration method in the case of linear bleeding.
