It's the annual 315 party. This year's 315 party is aimed at the egg that we eat almost every day. So is dyed eggs really much better than ordinary eggs? Is dyed eggs harmful to human body?
Before the party, CCTV reporters visited supermarkets all over the country and found that the prices of various kinds of "firewood eggs", "native eggs" and "stupid eggs" were twice as high as those of ordinary bulk eggs.
In the program, the supermarket staff knocked the local eggs on the spot, and sure enough, their yolks were more yellow than ordinary eggs. They claim that:
Pregnant women and children eat best;
It's not modern cage, but natural free range;
It's not synthetic feed, it's grains.
In the 315 evening party, a local egg named "under the acorn tree" was born by the local chicken who was free to feed in the forest and grew under the acorn tree all his life.
Is that really the case?
The reporter followed the address of the manufacturer on the box of these popular local eggs to Zhentang layer breeding Co., Ltd. in Guantao County, Hebei Province, and found that the matter was not simple.
In this farm, the reporter did not see the so-called "acorn tree" free range chicken for a lifetime.
Instead, I saw rows of caged chickens in the farm.
The boxes used to hold eggs in the warehouse were also marked with "native eggs".
So, how do these caged chickens produce redder eggs than ordinary eggs?
The person in charge of the company's cooperative farm told reporters that it was because an additive called "cantharidin yellow" was added to the chicken feed.
According to the No. 2045 regulation on the administration of feeds and feed additives issued by the former Ministry of agriculture, cantharidin yellow can be added to poultry feed as a colorant.
Yun Wuxin, a PhD in food engineering at Purdue University, told clove doctor that cantharidin yellow is an orange red pigment that can be directly used for food color matching.
However, compared with food, it will be more used in feed.
For example, eggs, chicken eat cantharidin yellow feed, can make the color of egg yolk look deeper and more attractive;
Salmon, for example, can make its meat more ruddy if you eat canthaxanthin.
According to the European Union's assessment, people's daily intake of cantharidin yellow dose is not harmful to health.
However, if we regard cage chicken as free range chicken, add colorant to chicken feed, package ordinary eggs into native eggs and sell them at a high price, is there no one to take charge of it?
Reporter investigation found that the original about native eggs, not only the lack of market supervision, businesses are also racking their brains to play routine.
1. There is no corresponding national standard for native eggs
Although there is no real national standard for the sale of eggs, they are not worried about it.
The so-called "egg" is no more than "egg".
Without specific regulations and disciplinary mechanism, it is not difficult to imagine the chaos of the local egg market.
2. Business "Li Gui becomes Li Kui"
In terms of trade names, in order to avoid inspection, businesses from all walks of life also played word games.
When you register a trademark, you only need to register a "native" and add the word "egg" to it. Then you can transform yourself into a native egg.
For example, the fresh and good native eggs exposed in the party are actually fresh and good native eggs, which are not the same as what you think.
Hubei liantian Food Development Co., Ltd. also said in the video: the industrial and commercial department came to find me. I have the registered trademark "fresh soil" egg.
The implication is: I didn't say I was a native egg, but you misunderstood me. My egg is a fresh native egg.
Do you agree with this routine?
There is no national standard, only folk saying, unscrupulous business take the opportunity to exploit loopholes.
When consumers see this, they just don't know how to buy real native eggs.
But then again, do you really think that the high priced local eggs you choose are more nutritious than ordinary eggs?
1. The nutrition of native and foreign eggs is not bad
The contents of protein, carbohydrate, cholesterol, calcium, zinc, copper and manganese in native eggs were slightly higher than those in fat, vitamin A, vitamin B2, niacin and selenium.
However, because of chicken eating, native eggs contain some flavor substances, which taste better.
2. Deeper yolk does not mean better nutrition
Egg yolk color is affected by additives in chicken feed, such as lutein, cantharidin (cantharidin) and so on.
Their effects on the overall nutrition of eggs are generally negligible.
Farmers may add more yellow corn, chili powder, carrots and other lutein rich foods to chicken feed, or directly add lutein, cantharidin (cantharidin yellow) and other colorants.
In this way, the yolk will naturally darken.
However, if one of them fails to control it and individual farmers violate the regulations to add industrial red pigment to the feed, the yolk will be particularly red, which will become the problem of "red heart eggs".
All in all, I would like to remind you that:
The yolk is darker, not necessarily more nutritious, but it will certainly be more expensive, and there may be some safety risks.
3. Is brown shell egg better than white shell egg?
Eggshell color is purely determined by the breed of hen, as for taste and nutrition, there is really no difference.
This year's 315 party also gave us a clear answer:
The nutritional value of native eggs and ordinary eggs is really no different.
If consumers don't believe in local eggs, businesses will have no chance to take advantage of them.
Let's cover our wallets and Buddha will eat the eggs.
