How to store oysters overnight without dying? What is the black mass inside the oysters?

Oysters are one of the most resistant aquatic animals. The changing environment of the intertidal zone over the past 200 million years has trained oysters to have strong resistance to temperature, salinity, air exposure and common pathogens in the sea. So how can oysters be stored overnight without dying? What is the black mass inside the oyster? Let's take a look at the introduction of Encyclopedia Knowledge Network!

How to store oysters overnight without dying

If you want to keep oysters alive overnight, you can place them in a clean basin, cover them with a wet towel, and then place them in the refrigerator. Alternatively, you can place the oysters in a basin and pour clean water into the basin to submerge the bottom of the oysters. When selecting oysters, you can listen to the sound. The varieties with dull sounds have full meat.

1. Refrigerator

If you want to keep oysters alive overnight, you can refrigerate them. After cleaning the oysters, put them in a clean basin, then cover the top of the oysters with a large wet cloth to maintain humidity, and finally put the basin in the refrigerator.

2. Soak in clean water

If you want to keep oysters alive overnight, you can soak them in clean water. After cleaning the shells of the oysters, pile them evenly in a basin, then pour clean water into the basin to cover half of the oysters, and then place them in a ventilated and shaded environment.

3. Selection method

When selecting oysters, you should look at the appearance and listen to the sound. Oysters of better quality will make a dull sound when knocked, and their shells are deeper and thicker, with tighter joints. Oysters of poorer quality will make a hollow sound when knocked, and their shells are shallower and thinner, with looser joints.

What is the black stuff inside the oyster?

The black stuff inside the oyster is the oyster's metabolites and mud. It is recommended to soak the oysters in salt water for about 1-2 hours before eating to drain out as much mud as possible. The stuff that is drained out is the seabed plants and natural seaweed that the oysters feed on.

How to choose oysters

When choosing oysters, you should observe the appearance, listen to the sound, and check the quality of the meat. If the shell is tightly connected, deep and thick, and makes a dull and low sound when knocked, and the meat is plump and saturated, then it is of good quality and relatively fresh. If the shell is loosely connected, makes a hollow sound when knocked, and the meat is less elastic, then the oyster is of poor quality.

1. Look at the appearance

When choosing oysters, you need to observe their appearance. Oysters of better quality have tighter shells without openings, and their shells are thicker and deeper. Oysters of lower quality have loose shells, indicating poor freshness. In addition, their shells are shallow and thin, indicating less oyster meat.

2. Listen to the sound

When choosing oysters, you need to listen to the sound. You can choose two oysters, hold one in each hand, and then knock them against each other. If the sound is dull and low, it means the oysters are of good quality and have more meat. If the sound is hollow and crisp, it means the oyster meat is dry.

3. Check the meat quality

The most intuitive way to choose oysters is to ask the merchant to randomly open an oyster and observe the texture of the meat. Fresh oysters have plump texture, while oysters that have been stored for too long will have shriveled texture.
