How to identify yellow croaker, how to choose yellow croaker

One is to look at the appearance, size and shape of the fish.

The body of the authentic yellow croaker is oblong, the head is relatively large, the tail peduncle is slender, the body is yellowish-brown, the ventral surface is golden yellow, the fins are yellow or grayish-yellow, the lips are orange-red, and more than two-thirds of the base of the dorsal and anal fins are covered with small round phosphorus.

And what unscrupulous traders use to pass off as yellow croaker is a fish very similar to it, called meagre. However, the body of the meagre is flattened and slightly curved. The head is small, the tail is slightly shorter, the dorsal part of the body is light gray, the sides are light yellow, the thorax, abdomen and the base of the anal fin are slightly red or orange-yellow, and there are many black-brown wavy fine lines obliquely anteriorly.

The second is to look at the color.

At present, most of the fake yellow croaker on the market is directly coated with pigment, and the yellow color of real yellow croaker is lighter and softer, while the color of domestic yellow croaker is generally heavier.

The third is to rub by hand.

For dyed fish, wipe the body of the fish with white toilet paper, which will generally leave a distinct yellow color on the paper; Colored fish that are frozen into large lumps (lumps) will also have a yellow color on the ice. Soak the false yellow croaker in the water for about 5 minutes, and the water may turn beer-colored.

The fourth is to look at **.

It is understood that the production of yellow croaker in China's sea area is very small, so it is more expensive. If you see a few dollars a pound of yellow croaker in the market, it will be more than one eye, and it is likely to be a dyed fake yellow croaker.

1.In fact, it is not complicated to distinguish whether to dye yellow croaker: the yellow on the belly of the real yellow croaker is naturally light yellow, and the belly and fins are darker and will not fade; The color of the dyed color is easy to fade, and it is even more obvious after the fish is thawed.

2.Yellow croaker and yellow croaker are similar in appearance, the biggest difference is that yellow croaker has a distinct yellow color, while yellow croaker is blue-gray.

You can tell it by the color.

Real yellow croaker, the color of the belly is not very yellow, it is a light light yellow, the color of the fins and abdomen is darker, when buying, you can gently wipe it with a paper towel, if there is a fading phenomenon, it must be shoddy yellow croaker, or it is a fake yellow croaker at all.

It can be distinguished by the body shape.

The mouth shape of the real yellow croaker is round, and it is very plump, and the body shape is relatively wide, although the false yellow croaker is relatively similar in size and color, but the mouth shape is pointed.

It can also be distinguished by the shape of the scales.

When buying yellow croaker, you can scrape off a piece of fish scales with a knife, real yellow croaker scales are round, while fake yellow croaker scales are oval.

What is the difference between fresh yellow croaker and frozen and thawed yellow croaker, and stale yellow croaker?

1. First of all, look at the gills of the yellow croaker, the gills of the stale yellow croaker are gray and black, and the gills of the fresh yellow croaker are bright red.

2. The eye mask of fresh yellow croaker is full, clear and bright, and the eyeball is dull after freezing or stale yellow croaker.

3. The meat of fresh yellow croaker is elastic, when choosing to buy, the fingers can rebound immediately after gently pressing to prove that it is relatively fresh, and the fish meat has collapsed after pressing, and it is definitely not fresh if it cannot rebound immediately.

4. Fresh and high-quality yellow croaker, the thickness of the belly will not be thicker than the back of the fish, otherwise it will definitely be an illegal business.

Yellow croaker that has been soaked or filled with water.

Yellow croaker is known for its yellow color, which is more pronounced on the abdomen, while healthy fish are almost white around the mouth and gills. Therefore, if the color of the mouth and gills of the fish is abnormal, it is a dyed fish. You can also peel open the mouth of the fish, if it is stained, there may be residual yellow water in the mouth.

To distinguish the authenticity of yellow croaker, one is to look at the appearance size and shape of the fish, the second is to look at the color, the third is to rub by hand, the fourth is to look at the **, the fifth is the time to market, and the sixth is to look at the scales and see the mucus.

Appearance size and shape:True yellow croaker with small round scales on the dorsal and anal fins at the base of the fin bars 2 3 or above.

The scales are uniform in color, natural yellow, no scars on the body, the body is oblong, the head is relatively large, the tail peduncle is slender, the upper body is yellowish-brown, the abdomen is golden-yellow, the fins are yellow or gray-yellow, and the lips are orange-red. Fish that are too yellow may be dyed.

Color:The yellow color of the true yellow croaker is lighter, golden yellow, and softer; Most of the counterfeit yellow croaker is directly coated with pigment, and the coloring is more red and yellow. Soak the false yellow croaker in the water for about 5 minutes, the water may turn beer-colored, and the yellow color will all fade; The real yellow croaker still retains its original body color.

Hand rubbing:For dyed fish, rubbing it with white toilet paper generally leaves a noticeable yellow color.

**：The medicinal value of large yellow croaker is very high, so it is more expensive. And the white croaker ** is lower, if you see a few dollars a pound of big yellow croaker in the market, it is necessary to have more eyes, it is likely that it is a dyed fake big yellow croaker.

Long-term consumption of dyed large yellow croaker is harmful to the body. According to experts, the pigment used to color the fake large yellow croaker is the synthetic pigment in the food coloring, which may be "sunset yellow" from its color.

Although "Sunset Yellow" is allowed to be used within the specified range, it is a synthetic pigment after all, and the aluminum color ingots in it contain aluminum elements. Long-term consumption of such fish can have a certain effect on the brain, especially for sensitive groups such as pregnant women and infants.

The yellow croaker before spawning is the tastiest and has the most nutrients in the body. During this period, the fish return to freshwater to spawn, which we call the fish flood season. In China, the flood season of large yellow croaker is around the Dragon Boat Festival, while the flood season of small yellow croaker is in the Qingming season.

If you want to eat the freshest yellow croaker, shoot at these two points in time. Of course, frozen fish will be frozen all year round**, and the longer it is frozen, the worse the nutrition and taste will be.

Look at the scales, look at the mucus:Fresh yellow croaker has clear eyes, neat and tight scales, and transparent mucus. Some spoiled yellow croakers have cloudy eyes, scales that fall off, mucus that is like a white mist, opaque, and may also emit a peculiar smell.

Yellow croaker is also known as yellow croaker. Born in the East China Sea, there are two hard stones in the head of the fish, called the fish brain stone, so it is also called the totoaba fish.
