Research advance on stable mechanism of endophytic fungi to red wine colour during the aging

Based on the fact that persistent mutation of vinous color was not conducive to the stabilization of vinous quality during the aging, research advance on the stable mechanism of endophytic fungi to colour of red wine during the aging, including investigative status and developmental dynamic at home and abroad, endophytes and pigment of materials in wine, including effect of endophyte on vinaceous color, and even the application of tracer method in wine was summarized, respectively. The relationship between diversity of community the endophytic fungi and the main pigment material in wine was existent objectively, also included the response mechanism on colony dynamic of endophytic fungi to the various pigment as well as substance related to color, which laid the foundation for exploring the relationships between endophytic fungi and wine color, and the variational mechanism of the color under endophytic fungi during the aging period of wine. Color as an important reference index of wine quality influenced not only the sensory evaluation of consumer, but also the quality of wine because of the self-aggregation or combination of phenolic composition with other substances under the endophytic fungi during the storage. Only steady wine in the color could guarantee the security of quality.
