Method of manufacturing compositions with high ganglioside content

摘要

A composition with a high ganglioside content is manufactured by a method characterized in that milk or milk-derived material containing ganglioside is dispersed in an ethanol solution so that the concentration of ethanol becomes 60~95%; after removing the precipitate which is generated by heating the solution to a temperature higher than 50° C., the obtained supernatant is cooled to a temperature lower than 0° C; and the obtained precipitate is recovered. The obtained composition with a high ganglioside content is used advantageously as a material for foods and drinks, medicines, chemical products, etc.
