Abstract
The present invention aims to provide extracts available for use in acidic beverage production and containing 2,5-piperazinedione,3,6-bis(phenylmethyl)-,(3S,6S)-, which is a useful substance with an improving effect on learning motivation. When an acid treatment step is included in the production of extracts containing 2,5-piperazinedione,3,6-bis(phenylmethyl)-,(3S,6S)-, it is possible to obtain acidic extracts which cause no sedimentation even when added to beverages. The extracts of the present invention can be added to beverages and so on without impairing the taste inherent to foods and beverages, and can be used for production of acidic beverages preferred by most consumers.
