Little did they know that these salted duck eggs had been tampered with by unscrupulous profiteers and contained a strong carcinogen, Sudan Red No.4..
The secret lies in adding an additive called "red medicine" to the duck feed of duck factory, which can be called "oil-soluble red" or something more attractive and pleasant to listen to, and all the eggs laid by ducks who eat this feed are red hearts. Then the duck eggs can be salted, cleaned and packaged before they can be put on the market.
CCTV reporters made an unannounced visit to this, and sent this sample of red duck eggs to the National Quality Inspection and Quarantine Center. After inspection, it was found that all the red salted duck eggs sent for inspection contained Sudan Red No.4.. Uncovering the Falsification of Red Heart Duck Eggs Drinking a bowl of porridge and eating a salted duck egg for breakfast is a pleasant thing for people who are used to Chinese breakfast. However, when you eat salted duck eggs with red oil, have you ever thought that red may be terrible Sudan red? At the beginning of 2006, a batch of Chili sauce from Heinz (China) was found to contain the carcinogen Sudan Red No.1. Since then, the name of Sudan Red has been known to everyone. Under the severe blow, Sudan Red, a ghost, withdrew from Chili sauce and Chili oil and quietly hid in the bright red hearts of duck eggs and eggs. Sudan Red reappeared as the more toxic Sudan Red No.4.. In 2006 1 1 month, CCTV's Weekly Quality Report revealed that some duck farms in Shijiazhuang, Hebei Province mixed Sudan Red No.4 into feed for ducks, making the yolk of duck eggs appear red. After curing, these inedible "red heart" duck eggs were called Baiyangdian specialty (it was later found that the duck eggs were stolen from the name of Baiyangdian and actually came from the surrounding areas of Shijiazhuang), and they were sold to consumers everywhere through factory outlets, wholesale markets and supermarkets. According to the survey, tons of salted duck eggs polluted by Sudan red flow into the Beijing market every day, most of which are sold in supermarkets and are widely welcomed by consumers. This salted duck egg sells well because consumers listen to the false propaganda of the merchants. The distributor of "Red Heart" duck eggs told consumers that the ducks in Baiyangdian lake prey on small fish, shrimp, water worms and aquatic plants, so the eggs laid are red hearts, and the nutritional value of this duck egg is much higher than that of the ducks fed with feed. However, the reporter's on-the-spot investigation found that these "red heart" duck eggs came from duck farms around Shijiazhuang. They were not free-range, nor were they born with red heart eggs, but they only produced red heart eggs after eating the feed with "Red Medicine" (containing 46.5% industrial dye Sudan Red No.4). Sudan Red No.4 is listed as a Class III carcinogen in the world. Compared with Sudan Red No.1, Sudan Red No.4 is not only brighter in color, but also more toxic. After the inspection of the red-heart duck eggs laid by ducks who ate "red medicine", the relevant departments found that in addition to salted duck eggs, fresh duck eggs were also polluted, which was extremely harmful to human body. A stone stirs up a thousand waves, and the "red heart duck egg" in Hebei has made all parts of the country start to strictly investigate local duck eggs, and the result is worrying. Farmers said: it is an open secret to add pigment to poultry feed, which is very popular in the industry. The red heart duck egg disclosed by CCTV is just the tip of the iceberg. When investigating Sudan red duck eggs, people also found Sudan red eggs. From this, we can't help but wonder: Will there be Sudan red quail eggs and Sudan red pigeon eggs ... to stay away from the problem eggs? (1) Distinguish the red-related fresh duck eggs. After the ducks have eaten the feed with Sudan red and other pigments, the yolk color of duck eggs is very uniform, and there is no difference. However, the yolk color of eggs laid by ducks will change with the seasons. In spring, the water level in lakes and rivers is shallow, the aquatic life is rich, the food source is rich, the nutrition is sufficient, the quality of duck eggs is very good and the yolk is red; In summer, there is more rain, higher water level, less food sources and lighter redness of egg yolk. In autumn, ducks feed on rice, and the color of yolk is yellow at this time; In winter, it is all fed by feed, and the yolk is light yellow. In addition, due to individual differences, the egg yolk color of the same batch of ducks will be different. This identification method is also applicable to other eggs. (2) Distinguishing that the salted duck eggs involved in red are harmless. After the "red heart duck eggs" are cooked, the yolk and egg white are yellow and white, and the yolk is orange, layered and sandy. After cutting, there is oil oozing out, and the taste is fragrant, not salty or light. Harmful "red heart duck eggs" have indistinct yolk and egg white, bright red yolk, unnatural color, no hierarchy, no sand, and hard taste. In addition, cut the problem "red heart" duck egg into two halves. After 20 minutes, the yolk will fade, and the middle core will change from red to yellow.
