What is it to sell such high-priced and rare yellow croaker?
Yellow croaker is divided into large yellow croaker and small yellow croaker, which are one of the four major marine species in China. Pseudosciaena crocea was once one of the important economic fish in China, and it is endemic to China. It is widely distributed from the south of the Yellow Sea in the north, through the East China Sea and Taiwan Province Strait, and to the east of Leizhou Peninsula in the South China Sea in the south.
Yellow croaker is rich in protein, minerals and vitamins, which has a good tonic effect on human body. For the weak and middle-aged and elderly people, eating yellow croaker will receive a good therapeutic effect.
Yellow croaker is rich in trace element selenium, which can remove free radicals produced by human metabolism, delay aging and prevent and treat various cancers. Yellow croaker has antibacterial effect and will stay fresh for a longer time than other fish.
Yellow croaker is delicious and can stimulate appetite. In addition, the white pheasant of yellow croaker can be fried and refined into glue, and then baked as yellow as beads, which is called swim bladder glue beads. It has the effects of replenishing essence and regulating qi and blood, and has good curative effects on digestive tract ulcer, pulmonary tuberculosis, renal tuberculosis, aplastic anemia and vasculitis.
As a valuable economic fish, Pseudosciaena crocea has long been favored by consumers. However, due to overfishing, the resources are seriously damaged.
Nowadays, there are too many inferior or fake yellow croaker dyed with other fish on the market. How should we choose when shopping?
1. The eyes are pale, the price is lower than the normal price, and it may be deteriorated.
2. Fish that are too yellow may be dyed.
3. Wipe the fish with white toilet paper, which will leave obvious yellow. It must be dyed with other fish to pretend.
4. The mouth and gills are also yellow. Those with residual yellow water in the mouth must be dyed.
A good yellow croaker has full and prominent eyeballs, transparent corneas and black and bright eyes. There is no scar on the body. The fish is oblong, with a large head and a slender tail handle. The upper body is yellowish brown, the abdomen is golden yellow, the fins are yellow or grayish yellow, the lips are orange, the meat is firm, elastic and the gills are clear. No peculiar smell.
In recent years, due to overfishing, resources have been seriously damaged. There are more and more cultured yellow croaker, and frozen yellow croaker is gradually appearing on people's dining tables. After rapid freezing, the nutrition of yellow croaker will not be lost, and the water is still sufficient. Liquid nitrogen is a mature refrigerant in recent years, and the liquid nitrogen quick freezing machine is also mature. The liquid nitrogen freezer uses-196 liquid nitrogen refrigerant. When it comes into contact with food, it can take away heat more quickly. This ultra-low temperature and high heat exchange rate realize real rapid freezing. It is precisely because of this rapid freezing that the ice crystals produced are minimized, which helps to maintain the texture of food, prevent the loss of water, almost achieve no loss, and maintain the original color, original flavor and original quality of food to the greatest extent.
Wild yellow croaker migrates and overwinters, but now most of the yellow croaker we eat are cultured in cages. I hope that with the efforts of human beings, wild yellow croaker can reproduce its former output.
