A method for removal of nematodes from fish liver comprises the steps of treating said fish liver with steam for a period of time sufficient to allow for the connective tissue membrane to contract, thereby pulling out said nematodes from respective depressions, and further treating said fish liver with steam for a period of time sufficient to allow for said connective tissue membrane to be released from the liver meat. A method for reducing the oil content of fish liver comprises the steps of at least partly detaching a tissue membrane from liver meat, and treating said fish liver with humid air of high relative moisture content for a period of time between 5 and 30 minutes, said humid air having a relative air humidity of 80 to 100%, and a temperature of 32 to 70°C. Apparatus for carrying out said methods are also disclosed. |
