Embodiment 1

[0031] A deep-sea fish freezing process with a long fresh-keeping time, comprising the following steps: Step 1: manually screen the non-decomposed and odor-free deep-sea fish caught from the ocean and transported back to the shore by ice; Wash the deep-sea fish in cold water to remove impurities and scales; step 3: wash the deep-sea fish with scales removed in cold water again, cut the deep-sea fish into regular pieces with a slicer after rinsing, and put the deep-sea fish pieces in Put it into the cleaning tank filled with distilled water, add citric acid and potassium phosphate in the distilled water, and then rinse the deep-sea fish pieces; step 4: take out the deep-sea fish pieces after washing, place them in cold water, add salt in the cold water Soaking; step 5: take out the soaked deep-sea fish pieces, and freeze the deep-sea fish pieces through a freezer; step 6: lay pre-made ice in the food packaging bag, and then use a vacuum packaging machine to freeze the deep-sea f...

Abstract

The invention discloses a deep-sea fish freezing process capable of prolonging preservation time. The process comprises the steps as follows: step 1, artificially screening deep-sea fishes which are caught from seas, preserved by ice cubes, transported to shores and not rot and odorless; step 2, placing deep-sea fishes which are qualified through artificial screening in cold water for washing to remove impurities and scales; step 3, washing the deep-sea fishes with scales removed by cold water again, slicing the washed deep-sea fishes into regular slices, placing the deep-sea fishes in a cleaning tank containing distilled water, and adding citric acid and potassium phosphate to distilled water. The citric acid and potassium phosphate components have the preservation effect and can keep original nutrients and taste of the frozen deep-sea fishes during thawing and use when applied to the deep-sea fish freezing process, meanwhile, by vacuum freezing packaging, the freezing effect is enhanced, the preservation time of deep-sea fishes is prolonged, and people can use the deep-sea fishes conveniently.

Description

technical field [0001] The invention relates to the technical field of deep-sea fish freezing, in particular to a deep-sea fish freezing process with a long preservation time. Background technique [0002] Deep-sea fish belong to more than ten families. They are characterized by large mouths and large eyes, and light emitters on one or more parts of their bodies. They are found in teleost fish in the depths of the ocean. The light emitters are used not only to trap prey, but also to To attract mates, deep-sea fish formed these special habits in order to adapt to the extremely stressful, extremely cold and dark living environment during the evolution process. The habitat of deep-sea fish is the most special in the world, because the competition in the deep sea is not as good as that on the shore or So intense in the shallow sea that many primitive groups survive to this day. [0003] Deep-sea fish live in the deep-sea area below 100 meters, so the fishing method can only be ...
