Jellyfish is a commonly used seafood product. The water content in the body of the freshly salvaged jellyfish is too high, the skin is firm, and there are a small amount of toxins in the body. Therefore, fishermen in coastal cities will soak it in water solution after successfully salvaging it. The main components of the solution are edible salt and minggong salt, which are constantly soaked and cleaned, and finally it will be dried. That can get rid of the toxins rich in jellyfish. After the successful solution, the skin color of jellyfish should be light red, and some jellyfish will be light yellow. And after drying, the epidermis is well-proportioned, so it is not suitable for rupture with hand lashen. At this moment, the "stale" jellyfish can enter the sales market for sale. There are some tourists or relatives and friends in the central region because they don't know the professional knowledge in this field. It is very likely that you will buy "fresh" untreated harmful jellyfish. At this moment, you must remind him that jellyfish must eat "stale".
Many families in northern areas like to pickle all kinds of radish and pickles early in summer to improve their meals when fresh fruits are scarce in winter. Pickled sauerkraut is also a kind of food that can't be just "fresh". Fresh fruit will produce a chemical called phosphate in the body during its growth, which is not harmful to the body itself. However, when vegetables and fruits are pickled, these substances will be transformed into nitrate through a series of reactions, and even nitrite will be formed as a carcinogen.
Generally, the proportion of toxic substances reaches the peak at fifteen days after pickling. If the pickling time exceeds thirty days, the harmful substances will be greatly reduced, and the pickled sauerkraut at this moment can be used for taking. Therefore, pickled sauerkraut must not be fresh, and freshly pickled vegetables and fruits cannot be eaten. However, although long-term pickling will reduce carcinogens in it, it will still leave a part in radish pickles. Nowadays, agriculture and animal husbandry have the technology of greenhouse vegetables, and we can buy fresh vegetables and fruits all year round. It is better to eat less such non-nutritious food.

And there will continue to be some parasitic eggs in pig blood, which will cause illness after entering the body.
