Method for making a food or biotechnological product using redox potential regulation

摘要

The invention concerns a method for producing a food or biotechnological productincluding one or more steps, said one or more steps being implemented in a medium,said one or more steps implemented in a medium being a fermentation step, whichconsists in: during at least one of the steps of the method in controlling the redoxpotential of the medium of the step concerned. Said method is characterized inthat it consists in carrying out the process as follows: regulating at a predeterminedsetpoint level the redox potential of the medium of the step whereof the redoxpotential is controlled by controlled additions of a process gas into the mediumconcerned; and proceeding to the step following the step concerned in the processwhen said setpoint value is reached so as to carry out at least one of said stepsof the process in reducing condition and at least one of said steps of the processin oxidizing condition.
