Description
Technical field
The invention belongs to the field of aquatic food protein raw materials exploitation, and in particular to a kind of krill shrimp of enrichment phosphatide
Rotten and production method.
Background technology
, averagely containing 4% or so fat, the ratio of wherein phosphatide especially DHA- phosphatide is higher for krill.Correlation is ground
Study carefully show DHA- phosphatide nervous system growth especially infant's brain development, safeguard cardiovascular health, antitumor activity
In terms of regulation with immunologic function, with good effect, and the absorption efficiency in human body is higher.Meanwhile, krill contains
There is the protein of 11.9-15.4%, containing whole essential amino acids, its biological value is higher than milk protein and
As meat protein.In conventional krill processing, lipid and protein generally can not realize efficient output simultaneously,
Cause resource waste and the energy it is poorly efficient.As krill contains 80% or so moisture, lipid is realized effectively to be enriched with
Meaning in positive processing is made it have.And the operation of some lipid-rich is due to method and improper, the gained product of parameter
Thing contains substantial amounts of free fatty, causes the low value of product, and increased the difficulty of later use.
Krill is the maximum single living resources of quantity on the earth, and biological total amount is about hundred million tons of 6.5-10, is referred to as
, there are huge industrial raw materials and medicines and health protection exploitation prospect in animal protein storehouse last on the earth.Krill has excellent
Different protein and lipid, and due to physiological metabolism feature, substantial amounts of fluorine in shrimp shell, is enriched, in defrosting or decay process,
Can be migrated to muscle, be caused the exceeded of fluorine in end-product.Therefore, on the basis of removing fluorine, how to realize that lipid is enriched with
Protein product exploitation and industrialization, become promote krill higher value application main thought.
The content of the invention
To solve the above problems, the invention provides a kind of krill shrimp is rotten, lipid is realized in krill albumen
The especially enrichment of phosphatide, while it is preferably minimized the content of free fatty, while realizing krill albumen and lipid
Prepare and efficient utilization, and be capable of achieving on land and processing on ship.
For achieving the above object, the invention provides a kind of rotten preparation method of krill shrimp, basic step is：Adopt
Meat；Add water crushing；Adjust pH value and temperature；Protease hydrolytic；Centrifugal dehydration；PH is adjusted after adding water neutral；Centrifugation, collects precipitation
The krill shrimp for being as enriched with phosphatide is rotten.
The krill shrimp of the present invention is rotten, and lipid content is 40-50/100g butts, and wherein phosphatide accounting reaches 38-
45%, the enrichment of lipid can be effectively realized, with higher nutritive value.In aliphatic acid DHA and EPA accountings reach 32% with
