た。[Means for Solving the Problems] The present inventors have conducted extensive research to utilize unused marine biomass resources as sources thereof in accordance with the demand for feedstocks of highly unsaturated fatty acid compositions for fish feed. As a result, the red alga Fudarac, which has never been known to contain these higher polyunsaturated fatty acids, prevents an abnormal phenomenon in marine fish culture.
It has been discovered that PA exists as a component of a suitable usage form, and it has been elucidated that it is a suitable material.

After removing the protein part and the sugar part by extraction with, the step of removing and extracting saturated fatty acids and hydrocarbons from the product itself by SC-CO 2 extraction can be included. The higher polyunsaturated fatty acid composition obtained by the present invention can remove palmitic acid by about 10% as compared with the organic solvent method itself. As a result, EPA is about 40

The organic solvent extract is dissolved in an organic solvent such as chloroform and an organic solvent and uniformly dispersed in 10-35 mesh sea sand. Coated Extraction and removal conditions are liquefied carbon dioxide with a high-pressure pump and a circulation type extraction tank (100 m
It was sent to l) and made into a supercritical state. The inside of the extraction tank was kept at a constant pressure by a pressure regulator, and the gas flushed under atmospheric pressure was guided to the separation tank to catch the removed substance. The amount of gas used was measured with an integrating flow meter. Pressure: 25.0 MPa, temperature 313K,
CO 2 flow rate: 1.05 to 3.00 dm 3 / min extraction removal time 10 to 30 hours, extracted sample: 10 g. The amount of the substance to be extracted and removed is about 0.1 g / g, which is white. The substance that has been removed has a reduced content of palmitic acid
Higher polyunsaturated fatty acids 38-45
It is a composition composed of a lipid comprising 30 parts by weight of a saturated fatty acid and 30 parts by weight of a saturated fatty acid.
