In daily life, we may see two kinds of shark fin, namely dried shark fin and shark fin, and their two preservation methods are also different. For dried shark fin, it is very important for us to protect it from moisture, and another point is to prevent insects or other impurities from polluting shark fin. So if we buy dried shark fin in our daily life, we can put it in some cool, dry and ventilated places, and then let it be exposed to the sun for a period of time.

If you buy wet shark fin in your daily life, the preservation method of this shark fin is simpler than that of dry shark fin. When we store the shark fin, we just need to wrap it in plastic wrap and put it in the freezer. It's best not to put it in the freezer, because the shark's fin will soften after freezing and taste particularly bad, or we will mix the soaked shark's fin with a little water and store it in the refrigerator, but we must remember to change the water frequently. If we preserve dried shark fin in our daily life, we only need to keep it in a cool, dry and ventilated place, or it will not rot for a very long time. But for wet shark's fin, we should check it in time when storing it, because it may stink or go bad, and the storage time is short.
