文摘

Pressurized CO2 extraction of remaining fat from fish meal has been carried out.

Extraction may be controlled by the solubility of the oil in CO2 in the first stage.

The lowest fat content in the fish meal was 0.7% at 39.5 MPa and 40 °C.

Production of fish protein concentrates at low operating T is beneficial.

Fish meal after SC-CO2 extraction presents lighter colour than the original fish meal.
