The present invention discloses a polyphenol compound coating liquid for refrigeration and preservation of abalones. The compound coating liquid comprises: sodium alginate, glycerol, tea polyphenols, a rosemary extract, a bamboo leaf antioxidant and water. The present invention also provides a preparation method of the polyphenol compound coating liquid. The preparation method comprises sodium alginate solution preparing, polyphenol solution preparing and polyphenol compound coating liquid preparing. The present invention also provides a use method of the polyphenol compound coating liquid. The method comprises the following steps: abalone pleopod is taken, the taken abalone pleopod is placed into the polyphenol compound coating liquid to be soaked; the soaked abalone pleopod is taken out to be drained, and the drained abalone pleopod is placed into a pre-cooled calcium chloride solution to be soaked; the soaked abalone pleopod is leached with cold water and the leached abalone pleopod is drained; and the drained abalone pleopod is put into a sterile preservation bag to be sealed and refrigerated. The method combines the coating technology, compound preservation agent and low-temperature storage together, which play a synergistic effect. The used method is simple in operation technology, less in device investment, small in operation space, low in cost consumption, low in energy consumption, and suitable for industrialized mass production.
