The ‘Hass’ avocado had been tested by DMA to study the stress relaxation properties under different storage temperatures. The Maxwell model and kinetics model were also used to build the shelf life prediction model. The results showed that there were no significant changes of stress relaxation property in 7 days when stored under 5℃, while it softened quickly after 5 days at 8℃. The stress relaxation properties changed significantly in 3 days at 25℃. The shelf life prediction models had been built by extracting the equilibrium modulus of elasticity(E₀), the main relaxation time(τ₁) and the viscous coefficient(η) of samples, respectively. Among them, the model based on the main relaxation time,with the relative prediction error of 8.57%, could predict the shelf life more accurately than the others. This conclusion is expected to be potential applications for shelf life prediction of ‘Hass’ avocado during the cold chain transportation and storage.
