The invention relates to a method for rapidly tenderizing meat. The method includes the steps of soaking the meat in a sodium bicarbonate solution for 60-70 minutes, adding an ultrasonic processor toconduct ultrasonic treatment on the meat in the sodium bicarbonate solution, putting the ultrasonically-treated meat in tenderizing treatment liquid again to be ultrasonically treated for 2-5 minutes,evenly spraying a vitamin C solution on the surface of the meat, and quick-freezing the meat from -28 DEG C to -40 DEG C. The treatment method is simple, the steps are easy to operate, and the treatment cost is low; through the mode of processing the meat through the combination of sodium bicarbonate and ultrasonic waves, and the tenderizing time can be shortened, the quality of the meat is improved; by quick-freezing the meat after spraying the vitamin C solution, the delicious taste of the meat can be kept to the maximum extent, the taste of the meat is improved, and the sales volume of themeat can be greatly increased.
