Snail, crayfish and flower beetle are three swordsmen in summer night market, but no matter how delicious they are, they must be fresh, so they must not be dead when choosing. How to tell if the snail is dead or alive? Let's have a look with Xiaobian.
Can snail eat when it is dead
Can't eat. The main component of snail meat is protein. After the snail dies, the protein will deteriorate and produce toxin. It is not edible. The snails themselves live with parasites in their bodies, let alone die. Besides, conch, conch and other shells are not fresh and will have peculiar smell. Besides, if you die, don't eat. I'm sure you can't eat them.
How to distinguish the living from the dead
1. See if it can reach out. What can reach out is alive.
2. Click the cover at the snail's mouth. If you press it, it will spring up to be a living snail. If you don't, it will be a dead snail.
3. The dead snail doesn't move in the water, and it will float up, and its body will be light. Because it's dead, so the muscle can't hold the film to protect itself (it's growing with the meat to block the opening of the shell). At this time, some of the film and the meat will fall out together.
4. Smell. If the whole bag of snails stinks, many of them must be dead. Of course, some of them survived.
5. The cover of the dead snail's mouth is obviously concave.
How can snail survive
1. Clean the snail mud, moss, etc. Find out the dead snail and leave the living snail in the water. Note that the water level should not be too high. It's ok if it doesn't pass the snail.
2. Place in a cool place. The living environment temperature of the snail should not be too high or too low. The optimum growth temperature is about 20 ~ 25 ℃. When the water temperature is below 15 ℃ and above 30 ℃, the feeding activity will stop. Because when the temperature is below 10 ℃, it will enter the hibernation state.
3. During the period, pay attention to changing water frequently, and pick out the dead screws to prevent the water from stinking.
4. During the period of feeding, put some vegetables, potatoes and so on, the time of keeping snails will be longer.
5. If you put it in the water for too long, the snail will die. If it needs to be preserved for a long time, you can pick out the snail meat and put it in the fresh-keeping room. Put the snail meat in a plastic bag into the fresh-keeping room of the refrigerator. It needs to be frozen for a longer time. Take it out at any time when you need it.
