The formation and dissipation of foams in Baijiu is a complex dynamic change process of liquid.Among them,the statistical size distribution and dissipation time of Baijiu foams are the most intuitive physical characteristics in this process,which are directly related to other physical characteristics of Baijiu as a liquid.The relationship between the visual characteristics of Baijiu foams and the physical characteristics of Baijiu,such as component proportion,surface tension,concentration and viscosity,was analyzed by experimental analysis of the statistical size distribution and dissipation time of Baijiu foams under different concentrations and components.The experiment found that the higher the concentration of Baijiu,the greater the surface tension coefficient,and the more 3-10mm diameter foam produced.The higher the concentration of Baijiu,the greater the viscosity,and the lower the surface tension coefficient,the longer the dissipation time of Baijiu foams.
