A method of preparing ganglioside

摘要

A method of preparing Ganglioside GM3 which comprises converting Ganglioside GD3 included in a raw material containing lipids into Ganglioside GM3 in situ is disclosed. The conversion of Ganglioside GD3 into Ganglioside GM3 is preferably carried out by thermal treating the raw material at a neutral pH zone ranging from 6 to 8 and at a temperature ranging from 60 DEG C to 140 DEG C. The raw material containing lipids preferably contains 10 wt% or more per solids of lipids.
