The difference between oysters and oysters, is oysters the same as oysters

Although many times and many places also refer to "oysters" as oysters, or strictly speaking, oysters belong to a type of oyster. However, in terms of zinc content, the difference between the two is striking: according to Yang Yuexin's Chinese Food Composition List (published by Peking University Medical Press in 2002), oysters contain zinc per 100g (code 12-4-109, excluding shell weight, water content), while oysters of the same weight (code 12-4-108, excluding shell weight, 82% water) contain only as much zinc as oysters, which is twice that of ordinary oysters.

In terms of zinc content, especially given its higher water content, oysters are definitely the best of the best, far ahead of other natural foods, and no other food can match it.

As a result, the oysters with the highest zinc content have long been recommended by nutrition science are "oysters", not ordinary oysters, which can be bought everywhere on the streets of Dalian.

Oysters are also known as oyster clams, oyster clams, oyster yellow, sea oysters, oysters, etc. There are many oyster species living in different sea areas, the oyster in Dalian area is "Dalian Bay oyster", which is triangular, the dorsal and ventral margin is figure-eight, the right shell is pale yellow on the outside, with loose concentric scales, the scales are undulating into waves, and the inner surface is white.

Oysters are one of the larger oyster species, and the large one with the shell can be more than a catty, and it is generally grown or cultivated in the place where the river and the sea meet, in the shallow sea of the brackish and half-light inner bay. Due to the limitation of suitable growing conditions, it is less abundant than other varieties, so its economic price is generally higher. The large oysters in the hotel, much larger than the ordinary oysters bought on the street, may be this oyster.

According to the Liangguang coastal theory, oysters and oysters are two completely different things, oysters are smaller, grow on the reef or other hard objects on the seaside, and have to be dug up with a small hoe to get their flesh, and their flesh is mostly pale blue; The oyster is generally called "big oyster," its flesh is white, there are wild and artificially farmed, its shell and meat are large, can be boiled, fried or roasted, the common roasted oyster is this thing.

Da Hao is also a kind of seafood, the scientific name is Omi oyster, is one of the four precious seafood in Qinzhou, the meat can be eaten fresh, can also be processed into oyster sauce, oyster sauce. With a protein content of more than 40 percent, oyster meat is nutritious and delicious, known as the "milk of the sea", and can also be used in medicine. Maowei Sea in Qinzhou Bay is the largest natural breeding area for oysters in China, and the quality of the seedlings is excellent, which is incomparable with other sea areas.

What is the difference between oysters and oysters?

When people at the beach say oysters, they mean oysters.

There is a dish that many people are obsessed with in the barbecue stall is grilled oysters, which makes many friends addicted to oysters, so they choose to buy some oysters to eat back, which is more economical. And when buying oysters, we often see an ingredient called oysters. So what's the difference between oysters and oysters?

In fact, the main differences are as follows: 1. In terms of size, oysters are larger and oysters are smaller. 2. In terms of meat quality, the meat quality of oysters is more fatty, fresh and tender, while the oysters are a little worse.

3. On the surface, oysters are higher, and oysters are cheaper. 4. In terms of eating methods, oysters can be eaten raw, while oysters cannot.

There is no difference. In essence, the two are the same, just different names for the same species.

As for whether it is called oysters or oysters, it mainly depends on the region of origin and people's habits. The north likes to call oysters, the south calls clams, as for oysters, it is somewhat introduced, especially after French oysters are introduced into the Chinese market as a high-end ingredient, high-end restaurants are willing to call oysters. Australian oysters are also very popular in the market right now.

Oysters are not the same as oystersOysters and oysters are two completely different creatures, but many people can't tell the difference due to their similar appearance, and the differences between the two are as follows

1. Variety differences:

Sea oysters generally refer to folded oysters, which belong to the genus Oysters of the class Flap Gill and belong to the genus molluscs, while oysters generally refer to oysters, which belong to the genus of bivalve oysters molluscs, and the two species are different.

2. Appearance difference:

The surface of oysters is generally wrinkled, the color is black, and the flesh is mostly light cyan, while the surface wrinkles of oysters are also obvious, but the color is black and white, and the flesh is mostly white.

3. Size difference:

Oysters are generally smaller and less fleshy, requiring a sharp knife to break through the shell, while oysters are generally larger and have more fleshy flesh, and can be broken directly when steamed.

4. Difference in growth environment:

Sea oysters generally grow on reefs near the sea, while oysters generally grow at the confluence of rivers and the sea, and attach to reefs with a depth of no more than 10 meters.

Oysters are the same as oysters.

Oysters (Latin name: Ostrea Gigas Thunberg) is a common name for the oyster family of the order Oysters of the Mollusk phylum Bivalves. Also known as sea oysters.

There are many types of oysters. According to statistics, there are more than 100 species found in the world, distributed in the tropics and temperate zones, China's coastal areas, oysters are widely distributed, and there are about 20 species in the Bohai Sea, the Yellow Sea and the Nansha Islands.

Oysters, also known as oysters or oysters (oysters), oysters, are shellfish, pure males and no females, so they get the name (oyster means male). Fresh oysters are the fattest after the winter solstice and before Qingming in the following year, and Lao Xing honorifics is the best time to eat fresh oysters.

Oyster fried: Oyster fried is a famous snack in southern Fujian, also known as oyster fried, in Hokkien dialect is oyster fried, the taste is fragrant and delicate. Main ingredients: fresh oysters, eggs, chopped green onions, a little sweet potato powder.

It is rumored that in 1661 A.D., the Dutch occupied Tainan, Zheng Chenggong led the troops from Luermen to attack, intending to recover the lost land, Zheng army defeated the Dutch army like a bamboo, the Dutch army in a rage, all the rice and grain were hidden, Zheng Jun was in a hurry to make wisdom in the lack of food, simply took local materials to mix Taiwan's special oysters, sweet potato flour with water and a and fried cakes to eat, unexpectedly passed down to future generations, became a popular snack in the province.

Oysters are oysters.

Oysters are a type of oyster that looks much the same, they are all common shellfish in the ocean, and they also have the same nutritional value. Due to the different sizes, the place of growth and the breeding time are different, so there are local name differences.

Northern oysters are called oysters, and southern oysters are called oysters. Shape: Oysters have two shells, the shell is triangular, the dorsal and ventral margin is figure-eight, and the right shell is pale yellow on the outside and white on the inside.

The surface of the oyster shell is uneven and large, and one with a shell can be more than a catty.

Morphological characteristics of oysters:

The shell can be divided into three layers in cross-section; The outermost layer is a thin and transparent stratum corneum, the thickest middle layer is a columnar structure composed of calcium carbonate called prismatic layer, and the inner layer is a sheet structure of calcium carbonate, called nacre. The shell is formed by secretion of the mantle underneath, which extends from the top of the shell to the ventral margin, and is a two-layer epithelial cell.

There is a membrane formed by connective tissue in the middle, and there are muscle fibers in the membrane to make it attach to the inner surface of the shell, and the edge of the mantle is thickened to form three folds, and there are radiating muscles and annular muscles in the inner fold to make the edges close to the shell. There are a large number of sensory cells or sensory organs on the middle fold, which have functions such as touch and vision. The outer fold has a strong secretory function.

It is called "oyster" in the north, "oyster" in the south, "oyster" or "oyster" in Guangdong and Fujian, "oyster yellow" in Jiangsu and Zhejiang, and "oyster" or "oyster" in the north of Shandong.

There is still a big misunderstanding about the name of oysters in the market.

Myth: Oysters are those that can be eaten raw.

It's not just oysters that are eaten raw that are "oysters", and there is no scientific basis for this claim.

Oysters are called "oysters" because of the way oysters are eaten raw from France, and the same charcoal-grilled method is called "grilled oysters". The name "oyster" is like a nickname, because it is relatively tall and easy to remember.

In the process of publicity, some merchants deliberately use "oysters" to attack "oysters" to beautify their products, so the saying that only those that can be eaten raw is called "oysters" has begun to circulate in the market.

But in fact, whether it is "oysters" or "oysters", whether they can be eaten raw depends on the conditions of the water where they are cultivated and the purification process. Under the condition that it has not undergone strict process purification, it is not recommended for consumers to eat it raw.

Myth: Oysters have a higher nutritional value.

Some people say that oysters have a higher nutritional value, such as 6 times more zinc than regular oysters, but this is wrong.

Oysters in different regions will have different nutritional values due to different water areas, different baits, and different species genes. However, in general, except for specific cultivated species, the nutritional value of oysters is about the same, and there will be no big differences.

Myth: Oysters are a type of oyster with large heads.

"Oysters" and "oysters" are the same type of creatures, and they can be called "oysters" or "oysters" regardless of their size.

The size of the oyster depends on the culture cycle and the genetics of the species. But in general, the longer the culture cycle, the larger the size of the oyster, the longer the culture cycle, the more likely it will be.

The existence of these names is mostly due to the problem of business propaganda and regional common names, which leads to the existence of some ambiguities. But we can say with absolute certainty that they are all the same kind of organism, and their scientific names are "oysters".

Oysters are not the same as oystersAlthough oysters are called oysters in many places, oysters should be a type of oyster, oysters are a kind of mollusks, triangular shape, and the color of the shell is pale yellow, while oysters are a relatively large variety of oysters, generally growing at the intersection of rivers and seas.

The value of oysters:

Oysters have both calcium and phosphorus, the combination of these two elements can be said to be very perfect, calcium is a substance that our body can not leave in the process of growth and life, because calcium constitutes our bones and teeth, and once a person lacks calcium in the body.

In the north, oysters are called oysters, and because they grow in different regions, they will have different appearances. In the south, whether raw or cooked, it is called oysters, and there are also called "oyster yellow" or "oysters", such as the famous snack "fried oysters" in southern Fujian.

The best time to eat oysters is in autumn or early spring, as the meat is tender and nutritious, and can be eaten raw. In some coastal cities, oysters are often found as an ingredient.

The differences between oysters and oysters include different variety attributes, different growth environments, different nutrient content, different tastes, and different appearances.

1. The attribution of varieties is different.

Although oysters and oysters both belong to the mollusk oyster family, strictly speaking, oysters are only one of the oysters, and in terms of appearance alone, oysters are one of the largest oysters and can grow to more than a catty. And the small oysters are not oysters at all, they belong to ordinary oysters.

2. The growth environment is different.

Oysters are relatively harsh on the living environment compared to ordinary oysters, and generally grow at the confluence of rivers and seawater, that is, the shallow sea environment that is half brackish and half light. Ordinary oysters, on the other hand, do not have such high requirements for the living environment, and can survive on ordinary seaside reefs. Therefore, the living environment of oysters is more complicated than that of ordinary oysters.

3. The content of nutrients is different.

Oysters are not only larger than oysters, but also have much higher nutritional value than ordinary oysters. Oysters contain several times more zinc than oysters.

4. The taste is different.

Oysters are larger than oysters, so they have more meat than oysters and are more nutritious than oysters, so oysters are delicious whether they are steamed or charcoal-grilled.

5. The appearance is different.

The size of the oyster is relatively small, the shell is rough, and the flesh of the oyster is mostly pale green, and the meat is relatively small; Oysters are larger, the shell is smoother than oysters, the oyster meat is mostly white, and there is a lot of sediment, there is more meat, the meat is full, and the weight is much heavier than ordinary oysters.
