Aboard ship processed with the complete krill in 1~2h after capture.
Existing krill processing technology is mainly to have used for reference the Processing Technology Development of fish meal.But fish meal and shrimp
Powder is having larger difference in terms of property of raw material and product performance.As fish meal raw material fish protein composition with krill have compared with
Big difference；Fat requires as far as possible low in fish meal process, and as far as possible more reservation fat is required in shrimp med process；Fish meal
It is not present pigment problem in process, there are the pigments such as degradable astaxanthin in shrimp med process.On the whole, shrimp med
The technical issues that need to address are far more than fish meal in process.
At present, krill shrimp med boat-carrying processing mainly using krill as raw material, continental rise processing mainly with
Freezing krill is raw material, is transported to by conveyer belt in digester, and digester heats for steam jacket, generally will be warm in pot

It heated denaturalization and then can not solidify completely, usually entered and boiled by the separation of solid and liquid of separation equipment with boil liquid
Among liquid, although there is also the muscle protein of fish forms, fish larger with krill difference to this process in fish meal processing
The content of myosinogen is relatively low in class muscle, and loss in this process is smaller, yield is impacted smaller.But the South Pole
In krill shrimp med process, the phosphatide that the loss of this Partial Protein is usually associated with emulsification is entered in boil liquid at the same time.
And existing digesting apparatus is when temperature control is more than 90 DEG C, krill begins to warm to temperature from into digester
Reach 90 DEG C take the dish out of the pot during, have substantial amounts of water-solubility protein dissolution into boil liquid.And substantial amounts of water-solubility protein is in pot
