Quality monitoring and cooperative regulation and control method for 3D printing of easily oxidized fruit and vegetable gel system

The invention discloses a quality monitoring and cooperative regulation and control method for 3D printing of an easily oxidized fruit and vegetable gel system, and belongs to the technical field of food processing. The method mainly comprises the following steps: preparing a printable gel system of the easily oxidized fruits and vegetables, preparing a printable edible film material, carrying out ultrasonic pretreatment, creating an internal environment of a modified atmosphere 3D printer with inert gas atmosphere, low temperature and ultraviolet irradiation, carrying out double-nozzle 3D printing operation under the specific environment condition, and in the printing process, carrying out 3D printing on the fruits and the vegetables. The oxidation degree of a product is monitored regularly through a machine vision technology, and the internal environment of the controlled atmosphere 3D printer is regulated and controlled on the basis. The easy-to-oxidize fruit and vegetable gel system is printed under contr
