There are those items for the further processing of fish products

According to the type of fish and the requirements of the product, it can be roughly divided into four categories: raw dried products, boiled dried products, dried salt products and seasoned dried products.

1. Raw and dried products: products whose raw materials are directly dried without salting, seasoning or cooking. The main advantages of raw and dried products are that there are few changes in the composition and structural properties of raw materials, good rehydration, less loss of water-soluble nutrients, basically maintaining the good flavor of the original varieties, and having better color.

2. Boiled dry products: products that are dried after being cooked with fresh raw materials occupy an important position in the dry processing of southern China. The product has good taste and color, is easy to eat, and can be stored for a long time.

3. Dried salt products: products that are dried after salting. Generally, it is used for the processing of large and medium-sized fish that are not suitable for raw and boiled dry and the processing of small trash fish that is too late to be boiled and dried.

The advantage is that the processing operation is relatively simple, suitable for processing in high temperature and rainy season, and the shelf life of the product is longer. There are two kinds of salt-dried products, one is fish products that are salted and dried directly in the sun, and the other is salted and then bleached and then dried.

4. Seasoned dry products: products that are dried after the raw materials are mixed or impregnated with seasonings, or the raw materials can be dried to semi-dry and then soaked in seasonings and then dried. Seasoned dried products have a certain preservation performance, most of the products can be used directly, easy to carry, is a cheap and nutritious product.

1.Whole fish can be made into preserved fish or canned food.

2.Some of the waste from edible fish processing is used to make fishmeal and fish oil.

3.After cutting, you can make surimi, fish balls, and cheese fish sausages.

4.Scraps can be used as pet feed, up to cat and dog feed, down to fish feed.

Lack of canned Gongbao fish fillet, crispy dried fish, red yeast fish fillet, spicy fish pieces, fish meal, fish skin.

Hello dear and happy to answer for you. Found for you: What are the products of fish scale deep processing:

1. The calcium component of fish bones and fish scales is mainly calcium phosphate, the content varies according to the type of fish, about 58%-62%, its composition is very close to human bones, and it is one of the raw materials for the preparation of food-grade calcium hydrogen phosphate. When the raw materials of fish bones and fish scales are insufficient, it is also advisable to supplement with poultry, pigs, cattle and bones. Food-grade phosphate is one of the most used additives in the world, with an annual consumption of hundreds of thousands of tons, of which dicalcium phosphate accounts for 30% of the total.

China's food additives industry started late, the production capacity is insufficient, a large number of imports every year, and the market prospect is broad. Method: Bone residue leaching method for finch cracking.

Process control points: rinse, hammer and grind to 80-120 mesh fineness; deoiling, low boiling point solvent extraction, boiling range -37—8; Acid leaching, at a temperature of 0-15, continuous acid leaching is carried out in series with an acid-resistant tank, and the concentration of dilute hydrochloric acid is 2-3%; Sophora sophora sylvestris pH, enzymatic hydrolysis, Bacillus subtilis neutral protease, temperature 50, 6 hours; membrane filtration; The filtrate is concentrated to 18% water content and molded; Drying, 60 hot air drying to 12% water content out of the mold; Vacuum-packed. Sensory indicators:

Light white to light yellow colloid, used as food industry adhesive, emulsifier, stabilizer. Nutrients: protein, a variety of trace elements, amino acids, etc.

Inspection: According to the Ministry of Health's "Food Safety Toxicology Evaluation Procedures". 2. The by-product dilute hydrochloric acid impregnating solution is rich in monocalcium phosphate and calcium chloride, which can be used as raw materials for the preparation of food-grade, toothpaste-grade and pharmaceutical-grade dicalcium phosphate.

The key points of the process are as follows: acid leaching solution purification; In addition to fluoride, defluorination with white carbon black and sodium chloride, toothpaste grade requires fluoride, food grade requires fluoride; Neutralization, the acid extract after fluoride removal is neutralized with lime milk, and the pH is controlled to 3-5;membrane filtration; Wash to neutral, centrifugal separation; airflow drying; crushing filtration; Wrap. I hope mine can help you and have a great day

For fish meat, fish heads, fish bones, fish scales, etc., biochemical methods can be used to extract high-efficiency bioactive ingredients and process and produce health care products. For example, fish bones are cleaned, minced, cooked, and treated with chemicals to obtain fish bone meal, which is a kind of calcium supplementation active agent; Fish scales are processed by collagen extraction process and fish scale fermentation solution preparation to obtain collagen, which is a tonic or food added ingredient; The fish head can be cooked, enzymatically hydrolyzed, reacted, filtered and other processes to obtain special flavor substances and condiments.

China is rich in crustacean aquatic resources such as shrimp and crab, and its processing and comprehensive utilization have high economic benefits. More valuable advanced nutrients and pharmaceutical products can be extracted from the "cephalothorax" and internal organs of shrimp, and chitin and other substances can be extracted from shrimp and crab shells. The seaweed industry has a promising future, and iodine, gum, alcohol, etc., such as alginate and mannitol, can be extracted from kelp.
