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

Mantis shrimp protein milk and production technology thereof

Technical field

The present invention relates to use the method for enzyme to prepare the protein technical field, especially relate to the production technology of from mantis shrimp, extracting Mantis shrimp protein milk.

Background technology

Mantis shrimp Squilla belongs to Crustachia, Stomatopoda, Squillidae, it is nutritious, the protein content height, but present utilization except that big, the fresh and alive mantis shrimp of individuality do human edible, major part is used to make three grades of fish meal, because the crust content height of this type of fish meal, processing technology is coarse, and the nutritional labeling loss is bigger, does not give full play to its due value.

Summary of the invention

The objective of the invention is provides a kind of Mantis shrimp protein milk in order to overcome the deficiency of prior art, and adopts enzymatic isolation method to produce the production technology of Mantis shrimp protein milk.

For achieving the above object, technical scheme of the present invention is: a kind of Mantis shrimp protein milk, and its production comprises following process:

With mantis shrimp raw material clean water wash clean, remove the silt dirt, send into and adopt slurry in the flesh separator, finish the separation circuit of crust and slurries, the gained crust can be used for chitin extraction, shitosan etc.; Slurries are sent in the reactor, add animal protease and food flavor enzyme hydrolysis, and reactant separates concentrated, and add flavor enhancement to eliminate the bitter taste that produces in the enzymolysis process, again through cooking disinfection, and the finally sealed packing; Also can further make pulvis.

The pulpous state object that prepared Mantis shrimp protein milk outward appearance is brown or maroon has shrimp, crab fragrance; Its predominant quantity percentage is: crude protein 〉=38%; Crude fat≤10%; Amino acid 〉=33%;

The percentage by weight of main component in Mantis shrimp protein milk during amino acid is formed comprises following composition: lysine 3.10%; Leucine 3.13%; Arginine 3.39%; Glutamic acid 6.62%; Glycine 3.11%; Ox semi-annular jade pendant acid 2.19%; Alanine 2.54%.

Owing to adopted technique scheme, a kind of Mantis shrimp protein milk of the present invention has strong shrimp, crab fragrance, be rich in the acid of ox semi-annular jade pendant, alanine, glycine, has significant food calling effect for aquatic livestock, improve the digestibility of feed, and nutritious, the feeding aquatic livestock, growth is fast, individual healthy and strong; The enzymolysis process that adopts, Mantis shrimp protein milk finished product yield can reach 18.5%, but the shell chitin extraction is made full use of; Animal protease and food flavor enzyme all are homemade, and market is on sale, technical maturity, and it is convenient to implement.

Description of drawings

Below in conjunction with drawings and Examples the present invention is described in detail.

Accompanying drawing is a process chart of the present invention.

The specific embodiment

Shown in accompanying drawing, Mantis shrimp protein milk production technology of the present invention is with mantis shrimp raw material clean water wash clean, remove the silt dirt, send into and adopt slurry in the flesh separator, finish the separation circuit of crust and slurries, the gained crust can be used for chitin extraction, shitosan etc.; Slurries are sent in the reactor, add enzyme hydrolysis, and the concentration of hydrolysis time control slurrying liquid is 15-20%, temperature is 45-55 ℃, and PH6.5-7.2 added animal prolease hydrolysis one hour earlier, the back adds food flavor enzyme, hydrolysis 3-4 hour again, then temperature is brought up to more than 80 ℃ and is killed enzyme 10 minutes; Reactant is separated, and filter residue can be used as feed; Dilute slurry is 36% o'clock adding flavor enhancement through being concentrated into moisture content, and to eliminate the bitter taste that produces in the enzymolysis process, again through 110 ℃ of boilings sterilization in 15 minutes, the finally sealed packing is the Mantis shrimp protein milk finished product; Underflow also can further be made pulvis after drying;

By the Mantis shrimp protein milk that above-mentioned technology makes, outward appearance is the pulpous state object of brown or maroon, has shrimp, crab fragrance; Its predominant quantity percentage is: crude protein 〉=38%; Crude fat≤10%; Amino acid 〉=33%;

Claims
