Variations of gas concentration of rocket pulp was eliminated or significantly decreased (p < 0.05), verifying our initial hypothesis. Both growth models were validated against various fresh‒cut vegetables of high respiration rate, modified atmosphere packaging, and packaging films, under isothermal and dynamic temperature conditions. Growth of pseudomonads and lactic acid bacteria (LAB) was primary modelled by Baranyi model, while growth rate was further modeled as a function of storage temperature and % CO 2 by a polynomial model. Model development was based on study of rocket pulp stored under 0–20% O 2: 20-0% CO 2: 80% N 2 at 0–15 ☌. The objective of this study was to develop a model system for the prediction of the impact of temperature and in-package % CO 2 on the microbial spoilage of fresh‒cut vegetables with high respiration rate independent of packaging characteristics and post-harvest physiology.
