Description
Technical field
The present invention relates to krill to shell the processing of shrimp med, more particularly, relate to the drying means of the shrimp that shells.
Background technology
Along with continuing to increase of population and falling sharply of ploughing, marine fishery resources has become the valuable source that people depend on for existence.Data display in " world fisheries and aquaculture situation 2012 " that FAO (Food and Agriculture Organization of the United Nation) issues, within 2011, global fishery total output is 1.54 hundred million tons, and wherein 1.31 hundred million tons eat for the mankind.Have 16.6% from aquatic products in world population animal protein intakes in 2009, visible, aquatic livestock albumen has become the important food proteins source of the mankind.But in recent years because overfishing causes fishery resources deficient, the whole world is fished for fishery production and fluctuated for years, open up new fishing ground, develop the only way that new fishery resources have become China and even whole world deep-sea fishing sustainable development.
Krill belongs to crustacean, has 85 kinds of krills in the world and lives among the ocean in the whole world.Nearly 7,8 kind of krill lives in marine site, the South Pole, and they are generally distributed in the marine site, the ring South Pole on the south 50 degree, south latitude, are therefore called as krill.The krill as fished species that usual people say refers to Antarctic krill (Euphausia superb), it is under the jurisdiction of Arthropoda (Arthropoda), Crustachia (Crustacea), Euphausiacea (Euphausiacea), krill section (Euphausiidae), krill genus (Euphausia), average life span 3 ~ 5 years, shrimp body length is become to be generally 5.5 ~ 6.0cm, weight at about 2g, the transparent shape of health.
Krill is the single living resources that on the earth, quantity is maximum.According to the data of FAO (Food and Agriculture Organization of the United Nation) 1985 estimation, the total biomass of krill about 1.25 ~ 7.25 hundred million tons, year can amount of fishing about 0.13 ~ 100,000,000 ton; And according to English, moral, U.S., add four countries researcher in 2009 estimation data, the biomass of krill is 3.79 hundred million tons.Although be difficult to provide numeral accurately, the biomass that krill is huge has made it to become the most important potential fishery resources of world's ocean-going fishing industry.
Krill is described as the protein resource treasure-house of the mankind, and protein content is up to more than 40% of dry weight, and high nutritive value.The amino acid comprehensive nutrient value ratio of krill, prawn, cow's milk and beef was once comparatively marked by the World Health Organization, result krill gets a mark of 100,96 points, beef, 91 points, cow's milk, prawn 71 points.According to detection, necessary 8 seed amino acids of human body, all have in krill, and account for more than 40% of protein content altogether.Visible, krill is the edible protein resources bank with great DEVELOPMENT PROSPECT.
Develop krill protein resource, note following problem: first, the South Pole is far away, and krill utilizes, about its transport preservation cost just accounts for the nearly half of raw material totle drilling cost from salvaging land of going on board.In krill, moisture is more than 80%, if can transport after the krill drying aboard ship after fishing for, can save a large amount of costs of transportation again.Secondly, the krill amount of being rich in is high, it is reported, take whole euphausia superba as the full powder of krill that raw material is produced, and Oil repellent, all higher than 1200mg/kg, seriously constrains the scope of its application.But the fluorine of krill is mainly distributed in crust and head, but in muscle, Oil repellent is lower, is generally only about 1/5 of head and crust.Research shows, in the transport and storage of krill, the fluorine in crust can move to shrimp, pollutes shrimp.Therefore, fresh krill of fishing for first is shelled again dry, low fluorine euphausia superba powder can be obtained.Again, be rich in grease in krill meat, transport under wet basis condition, easily there is hydrolysis and become sour in grease, affects krill product quality.By preservation transport again after krill drying, also contribute to the stability improving grease in shrimp med, and then improve the quality of shrimp med.
In sum, krill prepared by ship and to shell shrimp med, no matter from actual production aspect or economic benefit aspect, all tool is of great significance.But, to prepare with fresh krill of fishing for the shrimp med that shells aboard ship, should be noted following problem: 1, gentle drying condition: in krill meat, fat content is higher, is rich in phosphatide type polyunsaturated fatty acid in grease, very easily oxidative rancidity, therefore drying condition needs gentleness; 2, shorter drying time: narrow space on ship, be difficult to relatively large production equipment is installed, only have the compression drying time, just can enhance productivity; 3, prevent wall sticking phenomenon to occur: with krill meat for raw material drying powder process, to lose the support of shrimp shell, shrimp very easily glues wall and fouling in dry run.In view of the special operation condition on ship, the cleaning of drying equipment is comparatively difficult, therefore will overcome the generation of sticky wall scale formation in technical matters.
In view of the foregoing, the present invention utilizes low-temperature vacuum drying technology to prepare low fluorine krill aboard ship and to shell shrimp med, mild condition and production efficiency is high.In addition, adopt the drying receptacle with teflon coatings can overcome the generation of wall sticking phenomenon, be applicable to very much the special operation condition on ship.
