Problems solved by technology

[0005] Invention patent 200610029553.5 A preparation method of natural fish flavor, discloses a method of using fish meat as raw material, adopting single-enzyme hydrolysis or multiple enzymes to hydrolyze in sequence to prepare the precursor of natural flavor flavor, and then adding sugar substances, amino acids and thiamine The method of preparing fish essence by heating reaction of vegetables, but a large amount of by-products such as fish heads and fish bones have not been rationally utilized
[0007] Obviously, the current technical processing products are single, and the advantages of freshwater fish resources have not been rationally utilized. Fish heads and fish bones are rich in flavor substances, and a large amount of collagen, unsaturated fat, phospholipids and calcium have not been fully utilized.
Fish scales, fish skin, and fish fat contain a lot of high-quality collagen, and they are not properly utilized, while fish gills and fish intestines are not suitable for direct food raw materials

Embodiment Construction

[0037] Specific implementation examples of the present invention, take grass carp as an example:

[0038] 1. Grass carp is divided and processed according to the structure of the fish body as follows:

[0039] 2. Grass carp fillet processing: Grass carp is processed into 2-5 mm thick grass carp fillets, which are sold frozen, or seasoned with salt, pepper, chili, and cooking wine, fried or baked, packaged, and sterilized, and sold as ready-to-eat fish fillets .

[0040] 3. Grass carp surimi products: According to the classic surimi processing method, the meat is minced and added with appropriate amount of starch, salt, egg white, crushed and shaped. Processed into fish balls, fish fillets, fish cakes, fish sausages, fish ham, canned fish, etc.

[0041] 4. After the grass carp takes out the fish oil, the oil is squeezed out by a press machine, and then heated, refined, dehydrated, and filtered to remove impurities to obtain refined fish oil.

[0042] 5. Collagen and gelatin:...

Abstract

The invention discloses a clean manufacturing technique to fully use a freshwater fish. The key point of the invention is to dismember the alive fish according to the fish body organ structure, and process and make full use of the fish; the fish can be processed into fillets, surimi products, fish oil, collagen protein, glutin, crisp fish bone, fish condiment and series of pellet feed. The invention has the outstanding advantages that the manufacturing technique produces no solid waste, makes full and reasonable use of the material, saves resources and has no environment pollution.

Description

technical field [0001] This patent relates to the technical field of food processing, specifically, to the technical field of freshwater fish processing and comprehensive utilization. technical background [0002] my country is the world's largest freshwater fish production and consumption country. Freshwater fish processing has a long history. There are more than 30 kinds of freshwater fish processed products. Processing technology achievements and patents are constantly being introduced, but the technology integration is not high. In terms of comprehensive utilization and The added value of processing is not enough, the efficiency of freshwater fish processing enterprises is not high, and a large amount of waste is generated. The freshwater fish industry urgently needs technologies with high technology integration, advanced technology, marketable products, high raw material utilization rate, and good comprehensive benefits. [0003] As we all know, in the processing of fres...
