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.
