Research advance of stability mechanism on physicochemical, biochemical and microorganism trait of wine

Abstract

The stability of wine is an important feature during the wine aging, which is mainly reflected in the balance of color, taste and aroma during the wine aging. During the wine fermentation, the role of microbes and enzymes including the interaction between them caused the mutual penetration, combination, decomposition and transformation among the substances in connection with color, aroma and taste in wine, which led to the instability of wine. After the fermentation of wine, the long aging period could just stabilize the wine. Still, the quality of wine had changed a lot. Based on the indicative changes in wine, such as microbiological interactions, biochemical reactions as well as interactions between the microorganism and biochemical reactions, the impact of changes of the basic biochemical and physicochemical indices on the stability of red wine were reviewed, and developmental suggestions in the future were also put forward in this paper, in order to reveal the mechanism of instability through the effect of dynamic change on the stability of red wine and analyze the unstable root of the red wine, which could lay a foundation for further research, and provide help for actual production.
