Predictions of beta‐carotene losses were made with model systems stored under conditions simulating storage of dry foodstuff powders. The mathematical model utilized kinetic data collected under static conditions of water activity and oxygen concentration and was extended for the prediction of beta‐cartone retention under dynamic conditions. Results showed an excellent agreement between actual and predicted retention of beta‐carotene stored under dynamic conditions once the proper correction factor was used. The correction factor was required to compensate for different geometries which affected diffusion limiting reactions.
