Provided is a method for producing a composition containing plasmalogen derived from a plasmalogen-containing animal tissue, the method being without significantly decreasing an amount of plasmalogen derived the plasmalogen-containing animal tissue. A method for producing a composition containing plasmalogen derived from an animal tissue, the method comprising: (A) concentrating an alcohol extract of a plasmalogen-containing animal tissue, and (B) after diluting a concentrated product obtained by (A), allowing to stand under refrigeration.

A method for extracting naturally occurring oil bodies (oleosomes) from a material containing naturally occurring oil bodies (oleosomes) includes the steps of dispersing the material containing oleosomes in an aqueous composition to thereby obtain an aqueous dispersion of material containing oleosomes, extracting oleosomes from the aqueous dispersion of material containing oleosomes to thereby obtain a crude oleosome extract and isolating crude oleosomes from the extract by drying the crude oleosome extract. The dried oleosome powder may be used with a personal care product, a pharmaceutical product or a food product.
