Embodiment 1

[0058] The concrete steps of the comprehensive utilization method of aquatic product processing leftovers of the present invention are as follows:

[0059] (1) Production of astaxanthin, fatty acid and hydrolyzed protein products:

[0060] 1.1 Wash the leftovers from aquatic product processing, dry them in a vacuum low-temperature freeze dryer at 40°C until the water content reaches 3%, freeze and crush them to 40 meshes;

[0061] 1.2 To the raw material treated in step 1.1, add water 6 times of the dry weight of the raw material, adjust the pH value to 7, add lipase and papain, the weight ratio of which is 0.2% and 0.4% of the weight of the substrate, hydrolyze for 6h, after hydrolysis After 1 hour, add 0.3% flavor enzyme according to the dry weight ratio of the substrate until the hydrolysis is completed;

[0062] 1.3 After deactivating the product of step 1.2, put it into a decanter centrifuge at 3000 rpm for 15 minutes for solid-liquid separation to obtain a solid phase a...

[0078] The concrete steps of the comprehensive utilization method of aquatic product processing leftovers of the present invention are as follows:

[0079] (1) Production of astaxanthin, fatty acid and hydrolyzed protein products:

[0080] 1.1 Wash the leftovers from aquatic product processing, dry them in a vacuum low-temperature freeze dryer at 50°C until the water content reaches 3%, freeze and crush them to 50 meshes;

[0081] 1.2 To the raw material treated in step 1.1, add water 8 times the dry weight of the raw material, adjust the pH value to 7, add lipase and papain, the weight ratio of which is 0.4% and 0.6% of the weight of the substrate, hydrolyze for 8h, after hydrolysis After 2 hours, add 0.4% flavor enzyme according to the dry weight ratio of the substrate until the hydrolysis is completed;

[0082] 1.3 After deactivating the product of step 1.2, put it into a decanter centrifuge at 3000 rpm for 15 minutes for solid-liquid separation to obtain a solid phase and...

Embodiment 3

[0098] The concrete steps of the comprehensive utilization method of aquatic product processing leftovers of the present invention are as follows:

[0099] (1) Production of astaxanthin, fatty acid and hydrolyzed protein products:

[0100] 1.1 Wash the leftovers from aquatic product processing, dry them in a vacuum low-temperature freeze dryer at 55°C until the water content reaches 3%, freeze and crush them to 60 mesh;

[0101] 1.2 To the raw material treated in step 1.1, add water 10 times the dry weight of the raw material, adjust the pH value to 7, add lipase and papain, the weight ratio of which is 0.4% and 0.5% of the weight of the substrate, hydrolyze for 7 hours, and then After 3 hours, add 0.5% flavor enzyme according to the dry weight ratio of the substrate until the hydrolysis is completed;

[0102] 1.3 After deactivating the product of step 1.2, put it into a decanter centrifuge at 3000 rpm for 15 minutes for solid-liquid separation to obtain a solid phase and a l...

Abstract

The invention discloses a comprehensive aquatic product processing leftover utilization method which comprises the following steps: with processing leftovers of crustacean including fish, shrimp, crab and the like as the raw materials, cleaning, low-temperature drying, cryogenic grinding, complex enzymatic degradation, organic acid extraction, high-speed centrifugal separation, reverse osmosis dehydration, molecule embedding, high-pressure homogenizing, vacuum low-temperature cryogenic drying, pelletizing, tabletting, automatic bottled packaging production line processing and outer packing are carried out, and all high value-added bio-active substances including astaxanthin, protein, organic calcium, chitin and the derivative of the chitin namely chitosan in the aquatic product processing leftovers are extracted, so that resources are comprehensively and effectively utilized without waste discharge. According to the invention, the moderate bio-enzyme degradation technique is adopted, the whole process is carried out under the low-temperature condition, strong acid, strong base and toxic solvents are not used, the technological process is short, the industrial chain is long, and the products are high in bioactivity, various in variety, excellent in quality, safe to eat, wide in application fields, large in potential market, and high in comprehensive economic benefit.

Description

technical field [0001] The invention relates to the field of food biotechnology, in particular to a method for the comprehensive utilization of aquatic product processing leftovers, in particular to the extraction of astaxanthin, protein, organic calcium, chitin and its derivative chitosan from the aquatic product processing leftovers A complete set of production technology and related equipment, and provides energy-saving and environmental protection advanced technology for the recycling of organic sewage in production. Background technique [0002] my country's coastal and inland aquatic resources are abundant. With the increasing social demand, the aquatic product processing industry has developed rapidly. According to China Business Intelligence, during the "Twelfth Five-Year Plan" period, the key tasks of my country's aquatic product processing industry are to actively develop intensive processing, tap marine product resources, and increase the development and utilizati...
