The method extracts an extract containing sea cucumber saponins. The extract is separated from sea cucumber meat exclusively by a specific heat treatment without conducting any chemical treatment with the use of an enzyme, ethanol, etc. The method includes: a step for heating sea cumbers from a starting temperature to a target heating temperature by a first temperature gradient; and a step for decreasing the temperature by a second temperature gradient that is gentler than the first temperature gradient to thereby extract the sea cucumber extract. The sea cucumber extract is stored as a sea cucumber extract material in the form of a liquid concentrate, etc. Then an appropriate amount of the sea cucumber extract material is added to, for example, another sea cucumber extract material having been separated and extracted from sea cucumbers with a lower saponin content.

[Problem] To provide a food or a preparation which contains sea cucumber saponins at a constant ratio even in the case where saponin contents in sea cucumbers largely vary depending on sea cucumber individuals, catch areas, fishery seasons, etc. [Solution] A method for extracting an extract containing sea cucumber saponins, whereby the extract is separated from sea cucumber meat exclusively by a specific heat treatment without conducting any chemical treatment with the use of an enzyme, ethanol, etc., comprises: a temperature increase step for heating sea cumbers from a starting temperature to a target heating temperature by a first temperature gradient; and a temperature decrease step for, after heating the sea cucumbers to the target temperature, decreasing the temperature by a second temperature gradient that is gentler than the first temperature gradient to thereby extract the sea cucumber extract. The obtained sea cucumber extract, which has been separated from the sea cucumbers with a higher saponin content by the aforesaid method, is stored as a sea cucumber extract material in the form of a liquid concentrate, a dry powder, etc. Then an appropriate amount of the sea cucumber extract material is added to, for example, another sea cucumber extract material having been separated and extracted from sea cucumbers with a lower saponin content so that a sea cucumber material, a sea cucumber extract material, and foods, etc. using these materials, wherein the saponin content is maintained at a constant level, are provided.

The purpose of the present invention is to provide a method for efficiently separating selenoneine from a starting material, which contains selenoneine, without using an organic solvent. The present invention relates to a method for separating selenoneine, which comprises a process wherein an aqueous solvent extract of a starting material that contains selenoneine is subjected to a reverse osmosis membrane treatment.
