Title:
METHOD FOR PRODUCING LEARNING EFFECTIVENESS-IMPROVING AGENT AND LEARNING EFFECTIVENESS-IMPROVING FOOD PRODUCT COMPOSITION, AND TECHNOLOGY PERTAINING THERETO
Document Type and Number:
WIPO Patent Application WO/2018/181135
Kind Code:
A1
Abstract:
Provided are: a method for producing a learning effectiveness-improving agent and a learning effectiveness-improving food product composition which are capable of improving learning effectiveness in normal situations where physical or psychological stress is not a substantial burden; a learning effectiveness-improving agent and a learning effectiveness-improving food product composition; a use for the hot water extract of the root of Eleutherococcus senticosus in the production of the learning effectiveness-improving agent; and a method for improving learning effectiveness. This learning effectiveness-improving agent or learning effectiveness-improving food product composition to be used to improve operant learning effectiveness via visual pattern recognition in situations where there is substantially no physical or psychological stress burden is formulated from a dried powder obtained by pulverizing the root of Eleutherococcus senticosus and forming strips therefrom, obtaining a hot water extract from the strips, vacuum concentrating the liquid extract to a certain concentration, and obtaining a dried powder of the extract by spray drying, using a spray dryer, the concentrated liquid extract from which the ethanol-insoluble matter has been removed.
