METHOD FOR EXTRACTING CERAMIDE-CONTAINING MATERIAL OR CERAMIDE FROM WHOLE APPLES AND/OR APPLE JUICE EXTRACTION RESIDUE, AND COMPOSITION INCLUDING SAID CERAMIDE

摘要

[Problem] A method for extracting a ceramide-containing material or ceramide from whole apples and/or apple juice extraction residue. Furthermore, to ensure utility as a food, especially a functional food, or a raw material for a cosmetic or medicine, that includes the ceramide-containing material. [Solution] In the present invention, an adsorbent is added to an ethanol treatment solution of whole apples and/or apple juice extraction residue, the mixture is stirred and subjected to solid-liquid separation, and solid material precipitated from the solution is separated, after which water is added to the resultant concentrate and the temperature thereof is maintained, whereby the resultant settled component is recovered and dried to obtain a ceramide-containing material or ceramide. Using the ceramide obtained from whole apples and/or apple juice extraction residue, there are formed a composition for promoting production of hyaluronic acid and/or type II collagen, and a composition for promoting improvement of memory impairment and/or enhancement of the level of phosphorylation of extracellular signal-related kinases (ERK1/2).
