      Objective To explore the stability kinetics model of juice soysour soup beverage and establish rapid prediction method on stability for juice soysour soup beverage. Methods Based on the basic principles of chemical reaction kinetics and thermodynamics, the juice soysour soup beverage was used as the research object, and the accelerated precipitation method was used to detect the physical index including centrifugal sedimentation rate, particle size, absorbance and sensory evaluation value during the storage period of the juice soysour soup beverage. Results Regression equations between the Gibbs free energy and the centrifugal sediment rate (r2=0.9743), the regression equation between the sensory value and the centrifugal sedimentation rate (r2=0.9846), and the kinetic model between the sensory value and the centrifugal sedimentation rate and temperature were established. The average model error coefficient CV of the prediction model was 12.40%, which was less than 15%. Conclusion The model can accurately predict the stability of the product, providing a scientific and rapid method for predicting the stability of the juice soysour soup beverage.
