Abstract
The invention discloses ultrasonic-assisted heating pretreatment equipment for fresh sliced meat and an ultrasonic-assisted hot pot rinsing method. The equipment comprises an ultrasonic cleaning machine and a constant-temperature water bath kettle, the frequency of the ultrasonic cleaning machine is 40 KHz, and the power of the ultrasonic cleaning machine is 200 W; the temperature adjustment rangeof the constant-temperature water bath kettle is 85-95 DEG C; the temperature is 90 DEG C; the ultrasonic-assisted hot pot rinsing method comprises the following steps: adding water or a starchaqueous solution with the concentration of less than 5% into a water tank of the ultrasonic cleaning machine, and carrying out ultrasonic treatment on sliced meat in the water tank for 12 seconds; puttingthe sliced meat subjected to ultrasonic treatment into the constant-temperature water bath kettle for water bath for 12 seconds; performing instant eating or low-temperature preservation; and puttingthe sliced meat into a hot pot, and slightly rinsing the sliced meat for instant eating; wherein the hot pot is clear in soup and tender in meat.
Description
technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to equipment and a pretreatment method for ultrasonic-assisted heating and pretreatment of fresh meat slices. Background technique [0002] Shabu-shabu (hot pot) is currently a very popular delicacy. Cut frozen or fresh meat into slices, put the meat slices into boiling water, rinse until it turns white, and eat with seasonings. Rinse the sliced fresh meat and eat it with the rinse. The main meats are mutton and beef. Mutton has a strong fishy smell, and beef is more popular. [0003] Shabu-shabu has the following disadvantages: [0004] 1. During the processing of fresh meat, due to the cross-contamination of the fresh meat by the microorganisms on the surface of the slaughtered animals, the microorganisms on the surface of the fresh meat. Due to the short boiling time, microorganisms cannot be effectively killed. Shabu-shabu is not safe. [0005] 2. When...
