Abstract

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.

Description

technical field [0001] The invention relates to the technical field of seafood processing and fresh-keeping, in particular to a polyphenol composite coating solution for cold-keeping and fresh-keeping of abalone, a preparation method and an application method thereof. Background technique [0002] The meat of abalone is tender, the taste is smooth, the taste is delicious, and it has a very high edible value. It is regarded as the "crown of seafood treasures". However, the transportation and storage conditions of fresh and live abalone are high, the transportation cost is high, and the environmental changes in the transportation process can easily lead to problems such as low survival rate of abalone, decreased meat weight, and quality deterioration. The development of convenient, efficient and safe abalone preservation technology has great practical significance for expanding abalone series products and promoting the development of abalone processing industry. At present, a...
