Device and method for controlling analyzing and managing phases of conservation and/or processing of food in a mobile or fixed closed space comprising a user interface with elements for data entry (1) a master control unit with memory and software (2) a management means system of the physical parameters of the food and/or of the space in which said food itself (6) is inserted integrated means for controlling and measuring the pH means for controlling physical parameters of food and/or of the space in which said food (6) is inserted characterized by the fact that the master unit has a software program which has in memory of one or more foods to be conserved or transformed and for each food the succession of variations of the Physical parameters for each phase of conserving and/or processing which has for each phase a safety interval of pH where said software manages for each value of the pH measured outside the safety interval of each phase a management program of physical parameters of food and/or the space in which said food (6) is inserted to bring the pH value within the safety interval of pH that said integrated means for controlling and measuring the pH is provided with a calibration system of the means for controlling and measuring the pH (10).
