Problems solved by technology

However, because the high fluorine content of Antarctic krill is harmful to human health, it brings certain difficulties to the direct utilization of this biological resource.
Some researches try to deshell and process fresh shrimp on board immediately after fishing, but the yield of protein is low and the waste of resources is large. Now some countries transport it back after fishing to be processed into oil, and the mixture of shrimp shell and protein is used as Feed, etc.

Description

Technical field [0001] The invention relates to a process for preparing Antarctic krill and shrimp oil with low fluorine content. Background technique [0002] As one of the few trace elements with dual-threshold properties, fluorine plays an irreplaceable role in the construction of biological hard tissues and promoting the growth and development of biological organisms within an appropriate range. On the contrary, too high or too low are detrimental to the growth of organisms. The average concentration of fluorine in the world's oceans is 1.30 mg / kg. The fluorine content in marine animals is higher than that in terrestrial animals. However, despite this, the fluorine content in most marine organisms is still not high, with an average of n×10 -4 %. But Antarctic krill has a high fluoride content, reaching n×10 -1 %. [0003] Although the fluorine-rich organisms in the ocean are not limited to Antarctic krill, Antarctic krill, as the largest marine biological resource in the Sou...
