Problems solved by technology

[0002] Mantis shrimp Squilla belongs to Crustacea, Stomatopoda, and Squilliaceae. It is rich in nutrients and high in protein content. However, except for the large and fresh mantis shrimps that are used for human consumption, most of them are used to make tertiary fish meal. Due to the high content of carapace in this kind of fishmeal, the processing technology is rough, the loss of nutrients is relatively large, and its due value has not been fully utilized.

Embodiment Construction

[0011] As shown in the accompanying drawings, the production process of the mantis shrimp protein slurry of the present invention is to wash the raw material of the mantis shrimp with clean water, remove the sediment and dirt, send it into the meat harvester for pulp extraction, and complete the separation process of the carapace and the slurry. The obtained carapace can be used to extract chitin, chitosan, etc.; the slurry is sent into the reaction kettle, and hydrolyzed with enzymes. During hydrolysis, the concentration of the slurry is controlled to be 15-20%, the temperature is 45-55°C, and the pH is 6.5-7.2. Add animal protease to hydrolyze for one hour, then add flavor enzymes, hydrolyze for another 3-4 hours, then increase the temperature to above 80°C to kill enzymes for 10 minutes; separate the reactants, and the filter residue can be used as feed; the thin slurry is concentrated to water When the rate is 36%, flavoring agent is added to eliminate the bitterness produc...

Abstract

The mantis shrimp protein milk is used as phagostimulant for compounding aquatic animal feed and is brown or dark red slurry with shrimp and crab scent. It contains crude protein not less than 38 wt%, crude fat not more than 10 wt% and amino acids not less than 33 wt%, as well as rich taurine, alanine and glycine. The production process includes preparing mantis shrimp milk, separate shell and milk, hydrolysis of the milk with animal proteinase and flavor enzyme, separation and concentration of the reaction product, adding seasoning to eliminate bitter, steam to sterilize, and hermetically packing. It may be further produced into powder. It has excellent phagostimulant effect for aquatic animal, can raise feed efficiency and has rich nutrients.

Description

technical field [0001] The invention relates to the technical field of protein preparation by using an enzyme method, in particular to a production process for extracting mantis shrimp protein slurry from mantis shrimp. Background technique [0002] Mantis shrimp Squilla belongs to Crustacea, Stomatopoda, and Squilliaceae. It is rich in nutrients and high in protein content. However, except for the large and fresh mantis shrimps that are used for human consumption, most of them are used to make tertiary fish meal. Due to the high carapace content of this type of fishmeal, the rough processing technology and large loss of nutrients, it has not fully exerted its due value. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a mantis shrimp protein slurry and a production process for preparing the mantis shrimp protein slurry by enzymatic hydrolysis. [0004] To achieve the above object, the tec...
