The invention discloses a preparation method for abalone products. The method comprises the following steps: (a) abalone preprocessing; (b) abalone hot processing; (c) ultrasonic first-band reconstitution; (d) ultrasonic first-band reconstitution; (e) ultrasonic third-band reconstitution; (f) shaping; (g) ultrasonic seasoning; (h) cold air drying; (i) packaging; (j) sterilizing. Dried abalones are adopted as raw materials, ultrasonic reconstitution, ultrasonic seasoning and the moderate temperature processing technology are combined, the problems that the reconstitution time is long and seasoning is hard when the dried abalones are adopted as the raw materials to be processed into the abalone products are solved, the temperature is moderate in the processing process, the biological activity of the abalones is maintained in the products, and the nutritional ingredients are more easily absorbed. The abalone is tastier, the soft and tender characteristics of abalone flesh are protected, the delicious smell peculiar to the abalones is maintained, and the abalone products are instant and convenient to carry and eat.
