Abstract: The fresh egg yolk was separated into three components by organic solvent: nonfat components, polar lipids and unpolar lipids. Sensory evaluation and GC-MS were used to study the flavor compounds of the heated three components and the assembled samples. The result showed that the characteristic flavor of egg yolk was produced by the polar lipids and nonfat components. Unpolar lipids in egg yolk has little contribution to the characteristic flavor. The interactional result between the Mallard reaction and the lipids oxidation was the main way that produced the characteristic flavor of egg yolk.

Key words: egg yolk, volatile flavor compounds, GC-MS, sensory evaluation
