Abstract
The invention discloses a producing method of quick-frozen and flavored cod fillets and mainly solves problems that existing cod products have the poor flavor and short shelf lives. According to the producing method, fresh cod which is frozen and unfrozen by saline water is taken as a raw material, scales are removed, two sides of cod bodies are sliced along vertebras, and internal organs and belly bones are removed; the cod bodies are washed with running water and then placed in clear water again for ultra-high pressure processing; after processing, the cod bodies are subjected to primary quick-freeze processing, skins of frozen cod bodies are removed, and the frozen cod bodies are cut into fillets; then the fillets are sequentially immersed in a flavoring liquid to be impregnated to be tasty, immersed in a trehalose antifreeze solution for antifreeze impregnation processing, drained fillets are subjected to cold sterilization by the aid of an electron beam, quick-frozen, packaged and detected to be qualified, and the quick-frozen and flavored cod fillets are produced. The producing method adopts the advanced and reasonable process and is high in operability and high in production efficiency. The fillets produced with the method have the stable quality, the long shelf life, the fresh and mellow taste, the palatable sweetness and saline taste as well as the unique flavor.
Description
Technical field
The present invention relates to the preparation of aquatic food goods, the preparation method of the true cod fillet of especially a kind of quick-frozen seasoning.
Background technology
True cod English name cod, main marine site, place of production U.S. Alaska and Bering, be not only rich in nutrition, more famous without (lacking) bone with fine and tender taste, has very high edibility.True cod meat is delicate, high resilience, good taste; and there is the features such as low fat, low cholesterol, high protein; nucleoprotein containing globulin, albumin and phosphorus in its fish tallow; the nutrients such as vitamin A, vitamin D, calcium, magnesium, selenium; its magnesium elements contained has good protective effect to cardiovascular system; be conducive to the angiocardiopathy such as preventing hypertension, myocardial infarction, also having the necessary each seed amino acid of child development, is all-ages nutraceutical.
At present, the body of true cod goods fresh-cut on market and fish block, although maintain original taste, there is weak flavor, shelf-life short deficiency in it.
Summary of the invention
There is weak flavor, shelf-life short deficiency to overcome existing true cod body and fish block, the invention provides that a kind of technique is advanced, operation rationally, the preparation method of the true cod fillet of quick-frozen seasoning of strong operability.Adopt the true cod fillet of seasoning not only stay in grade, the long shelf-life that the method makes, and mouthfeel is fresh and tender, the fresh perfume (or spice) of taste, unique flavor.
The technical solution adopted for the present invention to solve the technical problems is: the preparation method of the true cod fillet of a kind of quick-frozen seasoning, it is characterized in that: it chooses freezing and the fresh true cod of thawing is raw material, scale, along vertebra, both sides fish body piece opened, gill, abdomen spur; Again be placed in clear water after being cleaned by fish body flowing water and carry out ultra high pressure treatment; After process, fish body is carried out a fast frozen, the fish body after freezing is removed the peel, cuts into fillet; Fillet being immersed successively baste, to carry out dipping tasty again, and immerse trehalose antifreeze solution and carry out freeze proof impregnation process, the fillet after drop liquid are through electron beam cold sterilization, and quick-frozen, packaging, detects qualified forming.
