| Abstract: | In the present study, the static and dynamic adsorption capacities of AB-8 macroporous resins for astaxanthin
from Antarctic krill shells were evaluated. The results showed that the maximum quantity of astaxanthin adsorbed was
476.2 μg per gram of dry AB-8. Ethyl acetate was selected as the elution solvent with a desorption rate of 98.7%. The
dynamic adsorption conditions were optimized as 2 μg/mL and 4 BV/h for astaxanthin concentration and flow rate,
respectively. Under the optimal condition, the astaxanthin in saponification solution was purified with recovery rate of
78.9% and purity of 92.4%. |
