Which parts of the chicken can't eat the tip of the wing or the bottom of the chicken
4hw.org: chicken is one of the most common meat on our table. It's cheap and delicious. But there are many rumors about chicken, such as the tip of the wing can't be eaten. Let's see which parts of the chicken can't be eaten.
Chicken is a kind of meat with good quality and low price, which is very popular. But compared with the big meat of pigs, cows and sheep, chicken gives people a feeling that there are too many parts. Sometimes when eating a large plate of chicken, they will encounter a very complicated problem -- which part of the chicken can you eat? At the same time, there are also rumors that some parts of various chicken can't be eaten: some say that the tip of the wing can't be eaten, because the chicken is injected at the tip of the wing, it will gather toxins; some say that the neck of the chicken Son can't eat because there are a lot of lymph on it. It's also said that chicken has a part called bursa of Fabricius, which has a lot of lymph and can't eat it.
Which of these statements is true or false?
'wingtip' & ne; 'wingtip'
There is a saying that the "wing tip" part of a chicken is the part where the chicken is injected and the lymph is located. It accumulates toxic and harmful substances and cannot be eaten. This confuses two concepts. First, there are two parts of a chicken's' tip wing 'and' tip wing '. The tail bones of chickens degenerate. The tail bones at the end are more and more integrated into a tail heald. The meat in this part is smooth and tender, which is called "sharp wing", commonly known as chicken tip, chicken triangle, chicken butt, etc., which is different from the sharp wing of chickens.
Second, the subcutaneous injection site of chicken is mostly in the place where subcutaneous tissue is rich, that is, the skin is more 'loose'. For injection near the wing, it is generally selected under the wing rather than at the wing tip, such as the subcutaneous prick of the vaccine. There are other injection sites on the chicken, not all of which can't be eaten. After all, antibiotics are to follow the circulatory system to swim the whole body. It's one-sided to only grasp the "residual injection site". Moreover, many antibiotics are given through drinking water. If the breeders operate in strict accordance with the relevant regulations, the residue of antibiotics will not affect the health of the consumers.
There are two structures that should be removed in the buttocks of chickens called 'sharp wings':' caudal fat glands' and 'bursa on the cavity'. These two parts are also easy to be confused.
The tail fat gland is the only fat gland on the chicken. There are two glands in total, which are symmetrically distributed on the dorsal side of the bottom of the chicken. Chickens use their beaks to peck the fat secreted by the tail fat glands to 'oil' their feathers, so as to isolate and protect them. In the standardized slaughtering of poultry industry, the tail fat glands are to be removed because their presence will pollute the quality of meat [1]. If it is slaughtered by itself, the live chicken is directly open to the external environment, and it is pecked by the chicken, which is easy to cause gland blockage or inflammation of the chicken, so it is better to remove it when eating.
gland
The bursa is located in the upper part of the rectum, which is the central lymphoid organ of humoral immunity. It is not only for chickens, but also for large lymphoid organs (such as thymus and spleen) of all animals, which often contain a large number of pathogens, cell debris, metabolic waste and other foreign matters that are not coming or decomposing. Even if cooked at high temperature, some thermophiles may not be killed.
The supraluminal sac was first discovered by Fabricius, an Italian anatomist, so it is also called Fabricius' sac. Bursitis of Fabricius has always been a high incidence in birds, so veterinarians often use the term "bursa of Fabricius" to prove that this part is prone to pathological changes. Once pathological changes occur, more pathogens and harmful substances will be accumulated.
In mammals, there is no bursa, but the appendix is similar to it. With the growth and development of chicken, bursa of Fabricius will gradually shrink and degenerate, leaving little remains. Due to the short date of coming out of the market, most of the broilers have been on the market before they degenerate; the layer has a long time to wait for it to disappear. For broilers slaughtered by standardized process [2], the sebaceous glands and bursa on the cavity are removed, so it is unnecessary to reprocess.
Other inedible glands in chickens
In addition to the two parts on the bottom of the chicken, other glands need to be removed during slaughter:
Ducks, geese and other waterfowls have a pair of lymph nodes in the neck, chest and waist, but there is no formed lymph node in the body of chickens, but whether it has a membrane covered lymph node aggregation. The lymph nodes around the intestine have been generally disposed of during slaughter and processing, and there are some obvious small lymph nodes under the neck epidermis. The lymphoid tissue is all over the animal body and cannot be removed completely. If these small lymphoid tissues do not have pathological changes, eating them will not do harm to health. If you like to eat chicken neck, but you are not safe, you can peel the chicken skin off your neck and eat it again.
Thyroid gland and parathyroid gland contain more hormones. For chickens, thymus gland, thyroid gland and parathyroid gland will be removed together with the remaining trachea when they are slaughtered in standardization, and they can be removed when they are slaughtering chickens.
What should we do about chicken offal?
Although the chicken's internal organs are small, they can also be delicious. In these organs, the spleen is the peripheral lymphoid organ which needs to be removed; the lungs and trachea are prone to contain pathogenic bacteria which also need to be discarded. Of course, not many people would like to eat these things. The Chinese call "chicken giblets" generally include liver, kidney, gizzard (muscle stomach), chicken intestines, etc., while some countries will include the chicken neck for soup.
The liver has metabolism, detoxification and other functions, while the kidney is responsible for excreting harmful substances, while the stomach and muscles grind food. These three viscera are directly related to the metabolism of some harmful substances, which may remain here; the heart has no such problem. Therefore, chicken liver, chicken kidney, chicken gizzard and Chicken Intestines should not be eaten frequently and in large quantities, but it is not necessary to worry about occasionally.
In standardized slaughtering, chicken offal is usually packaged and refrigerated separately from chicken. There are also some processes that pack the chicken offal after it is cleaned up and filled into the chicken belly, which can effectively reduce the pollution of meat and make eating chicken more reassuring.
