れ大変多い。このように、南極えびは食糧資源としての
価値が極めて高い。(Prior Art) Antarctic shrimp that live in the Southern Ocean have a high protein content and are excellent as nutritious foods. In addition, its abundant resources are abundant, and it is estimated to be 1 billion to 2 billion tons, although it varies depending on the calculation method and investigator. And
The annual catchable amount is estimated to be 50 to 70 million tons, which is very large. In this way, Antarctic shrimp are extremely valuable as food resources.
（発明が解決しようとする課題） しかしながら、この南極えびはふっ素の含有量が多い。

のに問題があった。(Problems to be Solved by the Invention) However, this Antarctic shrimp has a large content of fluorine.
Its content is much higher than the tolerance limits set by the US Food and Drug Administration (FDA) for food safety. In this respect, Antarctic shrimp had a problem in utilizing it as a food resource.
南極えびに含有されたふっ素は、主に穀部位に集積され

ている。しかし、この方法では脱穀の際に、穀が小さな
破片に破砕されて肉部位に混入する。このため、肉部位
のふっ素含有量が増加してしまう。The fluorine contained in the Antarctic shrimp is mainly accumulated in the grain part. Therefore, a mechanical threshing method has been developed as a method for reducing the amount of fluorine contained in the Antarctic shrimp. However, in this method, during threshing, the grains are crushed into small pieces and mixed in the meat portion. Therefore, the fluorine content in the meat portion increases.

有量が増加してしまう。したがって、南極えびが食品加
工用原料として不適当となってしまう。The caught Antarctic shrimp are frozen, transported, and processed. During this transportation and storage, the fluorine contained in the grain portion moves to the meat portion. Therefore, the content of fluorine in the meat portion increases. Therefore, Antarctic shrimp becomes unsuitable as a raw material for food processing.
それゆえに、この発明の主たる目的は、南極えびに含有
されたふっ素を、電気化学的特性を利用して減量する方
法を提供することである。Therefore, a main object of the present invention is to provide a method for reducing the amount of fluorine contained in Antarctic shrimp by utilizing its electrochemical characteristics.

3 AlF 6 etc. are combined and removed.
（発明の効果） この発明によれば、南極えび中のふっ素含有量を、簡単
な方法で減量することができる。(Effect of the Invention) According to the present invention, the fluorine content in the Antarctic shrimp can be reduced by a simple method.
この発明の上述の目的，その他の目的，特徴および利点

水準の電流を流す。(Example) The meat portion from which the Antarctic shrimp grain was roughly removed and water were mixed at a constant ratio and crushed. Then, the aluminum electrode plate is placed in an electrolysis tank in which the aluminum electrode plate is installed, and an appropriate level of electric current is applied to the aluminum electrode plate.
すると、南極えび中のふっ素がAlF6 -3およびNa3AlF6な
