Method for concentrating lipids

Solids containing lipid components or a dried product thereof,

• wherein 50% or more by weight of the lipid components is phospholipid, and
• wherein the solids containing lipid components are prepared by
• heating a squeezed liquid at a temperature of not lower than 50° C., the squeezed liquid being prepared by squeezing a whole crustacean or a part thereof in an unheated state so as to break down tissue of the whole crustacean or a part thereof and to obtain the squeezed liquid, and
• separating the heated squeezed liquid into solids containing lipid components and liquid containing water-soluble components,
• wherein the solids containing lipid components and liquid containing water-soluble components are separated by filtration and/or centrifugal separation.

Solids obtained by washing solids containing lipid components or a dried product thereof with water, or a dried product thereof,

• wherein 50% or more of the lipid components are phospholipids, and
• wherein the solids containing lipid components are obtained by
• heating a squeezed liquid at a temperature of not lower than 50° C., the squeezed liquid being prepared by squeezing a whole crustacean or a part thereof in an unheated state so as to break down tissue of the whole crustacean or a part thereof and to obtain the squeezed liquid, and
• separating the heated squeezed liquid into solids containing lipid components and liquid containing water-soluble components,
• wherein the solids containing lipid components and liquid containing water-soluble components are separated by filtration and/or centrifugal separation.
