floc can't be eaten.

It is not recommended to eat the black floc inside the sea rainbow, because this part is mainly a polymer of sand and soil, which will not only affect the taste, but even contain arsenic. If it is combined with vitamin C, it may also produce toxic substances such as trivalent arsenic or pentavalent arsenic, and then a poisoning reaction will occur. Therefore, this part should be removed when eating the sea rainbow. 2 how to clean the sea rainbow

The sea rainbow shell is usually dirty, so the sea rainbow shell should be cleaned with a brush, and if there are any missing feet, it should also be cleaned. First, grab the sea rainbow shell with one hand, and pull it out with the other hand, not too strong, so as not to break it, and then use scissors to lose the foot silk.

Drop a few drops of sesame oil into the clear water where the sea rainbow is stored, so that the sea rainbow will spit out the sediment by itself. After about 3 hours, just rinse it with clear water. Finally, pry open the sea rainbow shell and remove the black things in the middle. 3 is it true that the sea rainbow is toxic

The sea rainbow itself is not toxic, but it will eat some toxic algae. When it is ingested too much, the toxin will accumulate in the sea rainbow. Although this toxin is not too harmful to the sea rainbow, the symptoms of poisoning will appear after eating it.

Moreover, the toxin changes in the sea rainbow have certain regularity. Generally, in March each year, when the temperature rises and algae flourish, the toxin accumulation in the sea rainbow will also increase, and then it will gradually decrease in June, and the harm to human body will also be reduced. Therefore, the risk of eating sea rainbow is high from March to June, and it is not recommended to eat sea rainbow during this period. 4 symptoms of poisoning caused by eating sea rainbow
