Recently, hairy crabs have entered the best tasting period. The crab meat is full, the paste is yellow and oily, and the price is half as low as the initial stage of its listing. At present, the price of 2.5 Yangcheng Lake female crabs and 3.5 Yangcheng Lake male crabs are around 30 yuan/piece, while the price of 30 yuan/piece of female crabs and 40 yuan/piece of male crabs are around 50 yuan/piece, and the price of the rest of the production areas is even cheaper.
However, various misunderstandings related to crab eating have appeared on the Internet again. What should you pay attention to when picking crabs? What should you pay attention to when eating hairy crabs?
hairy crabs don’t have to just stare at “ Yangcheng Lake ”
Every year when hairy crabs are on the market, there is a saying “ bath crab ”. Some consumers do not eat " Yangcheng Lake hairy crab ", and some are worried that some hairy crabs are not produced in Yangcheng Lake, but "bathing crabs" that grow from outside the country and finally soak in Yangcheng Lake.
Little do you know that Yangcheng Lake hairy crab is no longer the only choice for delicious hairy crabs . Whether it is other production areas in Jiangsu Province, local Shanghai, and even Xinjiang and Northeast China, there are many delicious hairy crabs, which are cost-effective.
The famous Yangcheng Lake hairy crabs are produced in Jiangsu, but the relevant person in charge of Jiangsu Provincial Supply and Marketing Cooperative said that in addition to Yangcheng Lake in Suzhou, Jiangsu also has Nanjing Gucheng Lake, Changzhou Changdang Lake, Suqian Hongze Lake and Luoma Lake , Xinghua Ecological Wetland. The crabs produced each have their own characteristics, so consumers don’t have to keep a close eye on Yangcheng Lake.
For example, Nanjing Gucheng Lake is one of the natural lakes with the best water quality in Jiangsu Province. The water quality is clean and pollution-free, and it is a local backup water source. The crabs in Gucheng Lake eat "three meats, three vegetables and one soup": "three meats" include small fish, shrimps, and snails; "three vegetarian food" is soybeans, corn, and aquatic plants; "one soup" refers to the high-quality water source of Gucheng Lake. Overall, the crabs bred from Gucheng Lake have firm meat and high nutritional value.
Changzhou Changdang Lake is a larger shallow-type, aquatic and grass-type freshwater lake, and it belongs to a "guest water" type lake, commonly known as "live water", which can better nourish the hairy crab family, thus creating the fertility of Changdang Lake hairy crab . Among them, the honey crabs in Changdang Lake are a unique local area.
Suqian has Hongze Lake and Luomahu Shuanghu production areas. Compared with other waters, Suqian hairy crabs have the external characteristics of "large shells, blue-burned back, white belly, and strong golden claws", as well as the inherent characteristics of "red fat, fat paste, fresh meat, and slightly sweet", commonly known as "king crab".
As for Xinghua hairy crab , the biggest feature is that it is raised in ecological wetlands, with thin shells, large claws, and golden claws. The cream is yellow and full, winning the reputation of " Red Crab ".
At present, in order to facilitate Shanghai citizens to select special hairy crabs from different production areas, Jiangsu Province has selected some special products to cooperate with the Shanghai Supply and Marketing Cooperative to sell them through online and offline platforms such as "Supply and Marketing E-Home" and "Xianfenghui".
As for local crabs in Shanghai, the quality is getting higher and higher . For example, Chongming crab is no longer a "black crab". It is large in size and tight in flesh, and has a new font size of " Chongming Qingshui Crab ". Today, "Chongming Qingshui Crab" is still building an advantageous zone for agricultural products with Chinese characteristics. Songjiang , Pudong , etc. have also raised many local high-quality crabs. Some cooperative products have become the "Oscars" of the national river crab industry - the Grand Slam contestant of the "Best Germplasm Award", "Best Taste Award" and "Golden Crab Award" in the National River Crab Competition
Agricultural experts recommend that consumers should not "only origin theory" when purchasing, but can choose fat crabs based on the fullness of the crab belly button, the cleanliness of the crab cheeks, and the flexibility of the crab.
Pregnant women and postpartum women cannot eat hairy crabs?
Since ancient times, there has been a saying that "crabs are cold in nature". This is true. People with weak spleen and stomach should not eat too much crabs.
However, due to the "crab's cold nature", there are also many rumors. The most typical example is that "pregnant and breastfeeding women cannot eat crabs." Rumors say that pregnant women will have miscarriage after eating crabs, and that pregnant women will have a crabs that affect the quality of breast milk. The child will spit bubbles in his mouth and walk sideways.
Shanghai First Maternity and Infant Health Hospital Chief physician of obstetrics Duan Tao said that pregnant women and breastfeeding women can eat crabs, but it is not recommended to eat more . As for the statement of "eating crabs and spitting bubbles", it is even more nonsense. Duan Tao said, if it is true as the rumors say, wouldn’t it be like a child born with mushrooms when he was born with mushrooms? If he eats durian, he would be like a child born with mushrooms? "Please ask the rumor makers and disseminators to think and draw strange conclusions with their heels."
So, how many crabs are eaten belong to "don't eat too much"? You can refer to the "Diet Guide for Chinese Residents 2022". The guide recommends that adults consume 40 grams to 75 grams of aquatic products per day (based on the edible part), while the edible part of a 3-two hairy crab is about 60 grams. In other words, is not a lot for each person to eat about 4 taels of hairy crab every day.
But it should be noted that the crab heart, crab stomach, crab cheeks, and crab intestines of hairy crabs are not edible, so must be removed. Among them, the hexagonal flake-shaped crab heart is a great cold thing; the "bone triangular bag" crab stomach contains toxins and crab excrement; the two rows of white soft and loose substances on the abdomen are crab cheeks, which are the respiratory organs of crabs, and are prone to parasites inside; a black line from the crab stomach to the navel is the crab intestine, which contains crab excrement.
Will eating hairy crabs with these foods be poisoned?
hairy crabs have also become the protagonist of "food restraint". Some people say that hairy crabs cannot be eaten equally with persimmons, which are prone to poisoning.
says "poisoning" is exaggerated. It is mainly because crabs are high-protein foods. Eating them with these foods can easily cause gastrointestinal discomfort, but they are not "poisoning".
The human body consumes a large amount of high-protein food, which will create a huge demand for protease in the digestive tract, increase the burden on the digestive system, and cause discomfort symptoms. For those who eat less protein foods, eating too much crab can easily cause stomach upset.
As for persimmons, because they are rich in tannin , and they are combined with proteins, they will affect intestinal absorption, hinder gastrointestinal movement, and thus cause indigestion. Fruits similar to persimmons and contain tannic acid include pomegranates, hawthorns, etc.
If you want to avoid discomfort after eating crabs, you should also be careful not to eat with tea and pears.
Tea is rich in tannin . It combines with protein in crabs and is easy to coagulate, affecting intestinal absorption, slowing intestinal peristalsis, and causing constipation. Pears are cold in nature and eating them with hairy crabs is equivalent to "adding cold to cold", which can easily damage the spleen and stomach and cause indigestion.
It should be noted that there is a situation in that may be poisoned after eating hairy crabs - eating dead crabs or dying "support crabs" .
After the crab is about to die or die, the group oxyacid in the body will decompose and produce histamine . Histamine is a toxic substance. The longer the death time, the more histamine accumulated in the crab, the higher the toxins, and will not be destroyed by high temperatures. Eating this type of crab can easily lead to food poisoning.
