Sc-CO2 extraction of fish and fish by-products in the production of fish oil and enzyme

open access: yesBioresources and Bioprocessing, 2022
AbstractSupercritical carbon dioxide (Sc-CO2) is an alternative tool to extract lipid for the production of fish oil and enzyme from fish by-products (FBPs). In the application of Sc-CO2, this review covers sample preparation, lipid extraction operation, and characterization of fish oil and enzyme as final products.
