Method for detecting rheological properties of food

The invention belongs to the technical field of food detection, and particularly relates to a method for detecting rheological properties of food. The method comprises the following steps: a food sample to be tested is placed on a tray, after sequential pressure regulating by a pressure regulating valve and two-stage air filtering of air compressed by an air compressor, the air is adjusted to a specific pressure by an electric proportional valve, then the air enters a solenoid valve, finally enters an air chamber, and is ejected by a nozzle, and the ejected air acts on the surface of the foodsample to be tested to generate compression deformation. A laser displacement sensor collects deformation information of the food sample to be tested, an electromagnetic force balance sensor collectspressure information on the surface of the food sample to be tested, and the deformation information and the pressure information are fed back to an embedded microprocessor for processing, and finallythe rheological property i
