Abstract:In order to obtain the correlation between the weight loss rate and the texture characteristics of blueberries and to provide reference for preservation theory，the appearance quality and physical properties of the blueberries were determined and the blueberry cells were studied.And the weight loss rate and texture properties including hardness，longitudinal stress，chewiness，elasticity of blueberries were investigated at 4，10 ℃and 20℃.The linear regression，binomial and exponential functions were fitted to the weight loss rate of blueberries at different temperatures with time.Besides，the fitting curve and the degree of correlation were obtained.The relationship between the weight loss rate and texture characteristics of blueberries was explored，and the results showed that the loss of blueberries had a significant effect on its texture.
