Mantis shrimp protein milk and its producing process

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...

[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.
