In order to give useful information for the appropriate packaging conditions, respiration characteristics of fresh cut purple cabbage was clarified. The respiratory rate were determined by using closed system method. The changes of headspace gas concentrations in tank was determined, and the respiration rate model was established with no competitive inhibition Michaelis enzyme kinetics equation. The results showed that the respiratory rate of fresh cut purple cabbage was positively correlated with temperature. The lowest R~2 of the mathematical models of respiratory rate about fresh cut celery were 0.84 which indicating that the model has a very good fitting. It can predict the change of respiratory rate from the model. It will give useful theoretical and technical support for gas packaging design of fresh cut purple cabbage.
