A roast duck costs dozens or even hundreds of dollars in the store. Can you buy the cheap roast duck on the street that costs 18 yuan per person? Is this duck dead if it is sick?
In fact, everyone does not have to worry about the price. At present, we mainly have 3 varieties of edible duck meat.
The first type of is a regular hotel or hotel that uses Beijing duck (large roast duck blank). The growth cycle is about 40 days, and the feeding cost is about 30 yuan. This breed is usually the same as the roast duck in Guangxi and Guangdong.
The second type of is a large white duck . The growth cycle is also about 40 days, and the feeding cost is about 20 yuan. Generally, the salted duck, sauced duck, braised duck and frozen duck in supermarkets sold in the market are mostly this variety.
The third type of is a small white duck with a relatively short growth cycle, about 30 days, from feeding to slaughter, the cost is about 15-16 yuan. Most of the low-priced roast ducks on the street are this variety. Although
is cheaper than the other two, the cost of raising small white ducks is not low. Why can they be sold for 18 yuan per person?
This is mainly because, just like pork trotters, tenderloin, ribs, buttocks, small white ducks will be sold separately after slaughter. When selling, they are usually divided into the main body (including body, neck, head, etc.) and duck down , duck gizzards, duck feet, duck intestines, duck blood, etc.
In this way, the main cost used to make roast duck can be controlled within 10 yuan. Even after processing, it is profitable to sell it for another 18 yuan.
Therefore, low-priced roast duck on the street does not mean that it is a dead duck. If it can ensure that the ingredients are fresh and clean, it can still be eaten.
Dietary Guidelines generally recommend that adults eat 40-75 grams (raw heavy) of poultry and livestock meat every day. Duck meat is a type of poultry meat, rich in protein , and we recommend regular consumption. Duck meat is a top dish on the dining table and an excellent food for people tonic.
First of all, the duck meat has a better fat composition. The fat in duck oil is different from butter or lard. The proportion of saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids is better. More than half of the skinned duck meat are unsaturated fatty acids.
Secondly, duck meat is rich in B vitamins. Many B vitamins in duck meat are very high. For example, duck meat is rich in niacin . Intake of a certain amount of niacin every day is beneficial for maintaining many important organs and tissues, including the myocardium. Although roast duck is good, you should not eat
. There are many ways to cook duck. Among them, roast duck is very popular, delicious and nutritious. However, it should be noted that the oil of roast duck is roasted from the duck meat at high temperature, which contains trace carcinogens and peroxide that is harmful to the cardiovascular system. It is recommended not to use it again.
In addition, those duck skin that are roasted are relatively crispy, also contain some carcinogenic ingredients such as polycyclic aromatic hydrocarbon , and have a high fat content. Just eat some occasionally in small amounts. Don’t eat them often. Generally speaking, eating once a month is enough.
