Embodiment 1

[0034] A kind of frozen processing method of marine fish, comprises the following steps:

[0035] S1. Selection of raw materials: select sea fish that are caught from the sea, transported on ice, free from decay, odor, and impurities;

[0036] S2. Cleaning and sectioning: the sea fish selected in step S1 is placed in ice water with a temperature of 0° C. for cleaning, descaling, and sectioning;

[0037] S3, fresh-keeping treatment: soak the fish fillets obtained after sectioning with a fresh-keeping agent for 0.5 min;

[0038] S4, grading and draining: grade the fish fillets after fresh-keeping treatment, pass through the cleaning tank again, place them on stainless steel racks to drain, and the draining time is 3 minutes;

[0039] S5, soaking in refrigerant: soak the drained fish fillets in refrigerant for 5 minutes;

[0040] S6. Quick-freezing: pre-cool the single-freezer to -45°C, and then place the fish fillets soaked in refrigerant evenly on the single-freezer plate. Th...

Abstract

The invention discloses a freezing processing method for marine fishes. The method comprises the following steps of: selecting raw materials, cleaning, slicing, carrying out preservation processing, draining according to grades, dipping in refrigerant, carrying out quick-freezing, and packaging in vacuum. Through the method disclosed by the invention, quick-freezing time is greatly shortened, in addition, unfrozen marine fishes can keep a fresh taste like the taste obtained when the marine fishes are just caught from the sea, and nutrition zero loss is realized.

Description

technical field [0001] The invention relates to the field of frozen aquatic products, in particular to a sea fish freezing processing method capable of maintaining the fresh taste of sea fish and having a short freezing time. Background technique [0002] Fish is rich in animal protein, calcium, phosphorus, vitamins A, D, B1, B2 and other substances, and is easily digested and absorbed by the human body. Fish muscle fibers are thinner, with a large amount of soluble gelatinous substances, and the structure is soft. The taste, taste and nutritional value of sea fish are more favored by consumers. Most of the market sales of fish are fresh, and most of them are sold in the form of fresh fish near the place of production. However, for inland consumers, because they are far away from the sea fish production area, they cannot easily obtain fresh sea fish, so they usually buy frozen and processed sea fish. So far, the freezing liquid used for freezing fish fillets is mainly a mi...
