What are the differences in appearance between oysters and oysters

Both oysters and raw mussels are nutritious foods that are beneficial to the human body. They are similar in appearance and are both seafood, so people may confuse the two. Oysters and raw mussels are common at barbecue stalls. They are rich in protein, as well as calcium, iron, zinc and other trace elements that are beneficial to the human body. When we eat them, we need to distinguish them. The most intuitive difference is the appearance. Here we will introduce the difference in appearance between the two.

Oysters have been cultured for food since BC; pearls can be produced in the mantle of pearl oysters. The two shells of the oyster are different in shape, with a rough, dark gray surface; the upper shell is raised in the middle; the lower shell is attached to other objects, is larger, quite flat, and has smoother edges; the insides of both shells are white and smooth. The two shells are connected at the narrower end by an elastic ligament. There is a strong adductor muscle in the middle of the shell to counteract the tension of the ligament. When the shell is slightly open, the wave-like movement of the cilia draws water into the shell (up to 2 to 3 gallons of water flow per hour) to filter out tiny organisms. Most oysters are dioecious, but there are also hermaphrodites. (Edible oyster Ostrea edulis) Oysters breed in the summer. In some species, the eggs are released into the water for fertilization, while in others, fertilization occurs inside the female's body. The hatched larvae are spherical and have cilia. After swimming for a few days, they permanently attach to other objects and are harvested after 3 to 5 years.

Oysters: Oysters are in the shape of two shells, with a rough dark gray surface. There is a bulge in the middle part of the upper shell, and the lower shell is attached to other objects. The inside of the two shells is white and smooth, and there is a strong adductor muscle in the middle part. If a foreign object gets into the shell of an oyster, the oyster will secrete nacre to wrap the foreign object and turn it into a pearl. This is why people who often eat oysters can eat pearls.

Oysters contain a variety of nutrients that are beneficial to the human body, including zinc, taurine, calcium, vitamins, amino acids and so on. From these nutrients, you can see how high the nutritional value of oysters is. Let’s take a closer look below!

1. Every 100g of oysters contains up to 9.39mg of zinc. Men can meet the body's zinc needs by eating one oyster a day.

2. The taurine rich in oysters has obvious liver-protecting and choleretic effects, and it is also a good medicine for preventing and treating intrahepatic cholestasis during pregnancy.

3. Oysters are rich in trace elements and glycogen, which are beneficial for promoting fetal growth and development, correcting anemia in pregnant women, and restoring physical strength in pregnant women.

4. Oysters contain calcium, phosphorus, etc. Oysters are the best food for calcium supplementation. They are rich in phosphorus, which is beneficial for calcium absorption because calcium needs the help of phosphorus when being absorbed by the body.

5. The diamond element of vitamin B12 contained in oysters is an indispensable substance for preventing pernicious anemia, so oysters also have the function of activating hematopoietic function.
