description The invention belongs to the technical field of aquatic product quality assurance, and in particular relates to a quick-frozen packaging quality assurance method for frozen shrimps. The method includes the following steps: step 1, removing impurities; step 2, performing flexible package: putting the shrimps obtained in the step 1 on a thin sponge, wherein the shrimp bodies are in a spread state; step 3, performing refrigeration: spraying liquid nitrogen by using a liquid nitrogen spraying device to quickly freeze the shrimps obtained in the step 2; step 4, performing weighing: weighing the shrimps obtained in the step 3, measuring the sizes, and wrapping the shrimps tightly by using a thin sponge, wherein the shells and legs of the shrimps are in a constricted and contracted state; step 5,removing spines; step 6, performing vacuum packaging; step 7, performing straightening; and step 8, performing sealing. The packaging quality assurance method provided by the invention has a completesystem and a reasonable p
