Sudan dyes were detected in the eggs of the duck with red hearts

On both sides of the Yehe River in Pingshan County, Shijiazhuang City, there are some duck farms. The reporter found that almost all the ducks here produce "red heart" duck eggs. A duck farmer said that as long as the "red medicine" is added to the feed, the duck can lay "red heart" duck eggs, and the more "red medicine" is added, the more red the eggs will be laid by the duck.

The reporter found in the surrounding area of Shijiazhuang City that in addition to more than a dozen duck farms in Pingshan County, a duck breeding base in Jingcheng County is also using this "red medicine" to feed ducks. The reporter took some samples of "red medicine" and sent them to the Food Safety Research Institute of the Chinese Academy of Inspection and Quarantine for testing. The results showed that the "red medicine" contained 46 5 of the industrial dye Sudan dyes.

So, where does Sudan dyes, the industrial dye that duck farmers add to their feed, come from?

A few days later, the reporter met Zhu Laiyong, who provided "red medicine" to the base, at the Sunzhuang duck breeding base in Jingcheng County. According to Zhu Laiyong, "red medicine" is not mysterious, and it can be bought in some chemical stores in Baoding City and other places.

The reporter then found this "red medicine" in a large-scale chemical store in Baoding City. The person in charge of the store said that this dye is called "oil-soluble red", and it is not sold anywhere, but they have it here, and it can sell several tons a month.

Sudan dyes are mixed with feed and you feed them.

Sudan reds"The scientific name is Sudan, azo series chemical synthetics. It is mainly used for dyeing with oil paint, gasoline and other products. It is divided into four categories, and duck eggs are used in the fourth category, although less toxic, but the International Agency for Cancer Cancer classifies it as a group three carcinogens.

Metabolites are classified as Class II carcinogens.

Here's how to tell if an egg has Sudan dyes:

1. The color of the egg, carefully observe the color of the egg, if the shell is very bright and bright, it means that the egg is dyed with Sudan dye.

2. Shake the egg, gently shake the egg with your hand, and then listen carefully to the sound, if there is a liquid impact, then the egg is Sudan red egg.

3. The color of the egg yolk, open the egg, and then observe the color of the egg yolk, if the color is darker than the general egg, it means that the egg is Sudan red egg.

4. Sticky, open the egg, and then touch it to see if the egg is sticky, if it is very sticky, it means that it is a good egg, otherwise it means that it is a Sudan red egg.

Multi-yolk eggs and soft-shelled eggs:

Double yolk eggs, three yolk eggs are mainly the follicles in the hen ovary mature time is too close or mature at the same time, the mature eggs are constantly discharged to the fallopian tube, so that two or three eggs meet in the fallopian tube, and are wrapped together by the egg white or egg shell membrane, that is, two or three egg yolks are wrapped in the same egg shell, becoming a double yolk egg or three yolk eggs, and the formation period is mostly the chicken that has just laid eggs.

The eggshell is very thin, or even no eggshell at all, and it is called a soft-shelled egg. The main component of the eggshell is calcium carbonate, in the hen's food, it needs to contain a lot of calcium, if the food is lacking in calcium or vitamin D, or due to the reaction after the injection of chicken plague vaccine, or because the chicken is frightened after the peristalsis of the fallopian tubes is strengthened, the egg shell does not have time to form and is produced, etc.

In the absence of instruments, we can only judge from experience, first of all, why use Sudan dyes, that is, because the foreign chickens that want to feed the feed and do not feed the same egg yolk color as the stupid chickens, from the root point of view, it is also driven by interests, if you add Sudan dyes, I don't believe that no one will add, the interest is to use foreign eggs to pretend to be stupid eggs, know these are easy to do, if the egg yolk is very red or even blood red and other characteristics do not match the stupid eggs (see the identification of stupid eggs for details) that is Sudan red eggs, In addition, the egg yolk containing Sudan dyes will change from red to yellow and white when boiled.

2. Gently shake the egg with your hand, and then listen carefully to the sound, if there is a liquid impact, then the egg is Sudan red egg.

3. Open the egg, and then observe the color of the egg yolk, if the color is darker than the average egg, it means that the egg is Sudan red egg.

4. Open the eggs, and then touch them to see if the eggs are sticky, if they are very sticky, they are good eggs, otherwise they are Sudan red eggs.

In the absence of instruments, we can only judge from experience, first of all, why use Sudan dyes, that is, because the foreign chickens that want to feed the feed and do not feed the same egg yolk color as the stupid chickens, from the root point of view, it is also driven by interests, if you add Sudan dyes, I don't believe that no one will add, the interest is to use foreign eggs to pretend to be stupid eggs, know these are easy to do, if the egg yolk is very red or even blood red and other characteristics do not match the stupid eggs (see the identification of stupid eggs for details) that is Sudan red eggs, In addition, the egg yolk containing Sudan dyes will change from red to yellow and white when boiled.

Identifying Sudan Red Eggs:

At first glance, the fake eggshell is more bright;

Second, fake eggs are easy to yellow after shaking, while real eggs will not;

Three-identified, real eggs are more viscous after opening; Four-shake, fake eggs shake up to have a sense of shaking inside, while fresh real eggs do not, and older eggs may also have this problem;

Five observations, observe that real eggs have a thin film between the eggshell and the egg white;

6. Boiled and boiled fake eggs, the yolk elasticity is relatively large.

1 There is a simple and easy way to preliminarily eliminate "Sudan dyes", if you have doubts, you can see whether the food colorant is soluble in water, "Sudan dyes" is insoluble in water, soluble in organic solvents such as chloroform, etc. 2 The color of the pepper noodles without Sudan red is natural, golden yellow. After adding Sudan dyes, the color is very bright and unnatural.

The color of natural paprika will slowly fade as the storage time is extended, or it will slowly fade when we are exposed to the sun; The paprika with Sudan red is bright in color and will not change color after being stored for a year. The public can take a container, take a little chili powder and put it in, and then add a little cooking oil to stir, after a few hours the color of the oil is very red, it may be added Sudan dyes, if the color changes little, it means that Sudan dyes.

1. There are several identification methods: good quietly.

In summer, the food ** decreases, and the red color of the egg yolk becomes lighter. In autumn, ducks eat rice as their staple food, and the egg yolk is yellowish in color. In winter, the egg yolk is light yellow, and the duck eats the feed with Sudan dyes, and the egg yolk color is not different from the four seasons.

3. When boiling eggs: because the artificially added pigment is easier to separate, it will float on the surface of the water or dissolve in the water when placed in water.

4. When cutting eggs: In fact, duck eggs with natural red egg yolk have "red and yellow" egg yolks, and after cutting, you can clearly see that there is red oil flowing out, which is delicious. The yolk of the eggs laid by the ducks who have eaten the "red" feed is bright red, and the salted duck eggs made from it can smell the smell of cornmeal after being cut, and the yolk is hard and dry.

According to relevant experts, first look at the color of the egg yolk. The yolk of a red-hearted duck egg is very red, while the yolk of a regular duck egg is yellow. Secondly, the red duck eggs contaminated with Sudan Red No. 4 are not easy to cook.

Beat the eggs into a pot and boil, the yolks are hard to cook for 10 minutes. Normal duck eggs (including natural red duck eggs) will definitely be cooked in 10 minutes, and the yolk will be powdered.

Color identification: The Sultan Red Duck Egg is an egg laid by free-range ducks, and the color of the yolk will change with the seasons.

Distinguish when boiling eggs: Sudan red duck eggs will not fade, and artificially added pigments are easier to separate, and will float on the surface of the water or dissolve in water when placed in water, so when boiling eggs, if you find that the color of the water has changed, it means that it may be artificially added pigments and is not edible.

Distinguish when cutting eggs: The yolk of Sudan Red Duck Egg is naturally red, and after cutting, you can clearly see that there is red oil flowing out, which is delicious. The yolk of the eggs laid by the ducks that eat the red feed is bright red, and the salted duck eggs made from it can smell like cornmeal after being cut, and the yolk is hard and dry.
