Hybrid Modeling and Optimization of Yogurt Starter Culture Continuous Fermentation
نویسندگان
چکیده
Abstract: The present paper presents a hybrid model of yogurt starter mixed culture fermentation. The main nonlinearities within a classical structure of continuous process model are replaced by neural networks. The new hybrid model accounts for the dependence of the two microorganisms’ kinetics from the on-line measured characteristics of the culture medium – pH. Then the model was used further for calculation of the optimal time profile of pH. The obtained results are with agreement with the experimental once.
