Delicious eggs, enjoy health! Seven questions you want to know about eggs.

Eggs are one of the most used ingredients in daily life.

An egg contains about 7 grams of protein, all 8 essential amino acids needed by human body, and rich lecithin. Moreover, the protein species and amino acid composition ratio of eggs are perfect, second only to breast milk.

In addition, the price is close to the people and the production methods are diverse. Eggs are the cheapest food on earth.

Because it is the most common and commonly used food, there are also the most questions about eggs.

one

Can eggs be eaten raw?

It is not recommended for the elderly to eat eggs raw.

Eating raw eggs is risky.

1. is infected with acute gastrointestinal diseases.

Pathogenic bacteria such as salmonella easily penetrate eggshells and invade eggs; If the eggs are not completely cooked, elderly children or pregnant women with weak resistance may have acute gastroenteritis after eating eggs contaminated by pathogens.

2. Not easy to digest and absorb

Raw eggs contain antitrypsin, which can inhibit the decomposition and absorption of protein by gastrointestinal digestive juice; At the same time, raw eggs are liquid, so they stay in the gastrointestinal tract for a short time and are not easy to digest and absorb.

After the eggs are cooked, the nutrition is not destroyed. On the contrary, due to heating, the digestion and utilization rate of protein is improved.

3. Increase the burden on the liver

Undigested protein, under the action of Escherichia coli in the lower part of the large intestine, produces some toxic substances, some of which will be reabsorbed by the intestine and enter the liver through blood circulation, increasing the burden on the liver.

4. Increase the infection rate of Toxoplasma gondii

The infection rate of Toxoplasma gondii in eggs has been unclear in academic circles. But eating cooked eggs is safer than eating raw eggs.

The US Department of Agriculture has issued relevant reports to remind the public:

If eggs can be kept at a fresh-keeping temperature below 7.2, the diseases caused by them will be reduced by half; Eggs heated above 7 1 can fully kill pathogenic bacteria and should be eaten as soon as possible after being heated to maturity.

In fact, in addition to the common eggnog (beer or white wine with raw eggs) and raw egg dipping sauce (some Japanese hot pot will serve raw eggs directly), there are mayonnaise raw eggs, tiramisu (a dessert) and homemade ice cream, all of which should be paid attention to.

two

Is it better to boil eggs or boiled eggs?

The yolk of cooked eggs is completely solidified and hardened, but the yolk of Lian Xin eggs is not completely solidified.

1. Nutritional value

Whether it is protein, minerals, etc. It's basically the same.

2. Safety and health sector

Cooked eggs dominate. The temperature of 7 1 can fully kill pathogenic bacteria, while the yolk begins to solidify around 68. The yolk of the heart-shaped egg is still semi-liquid, indicating that it has not reached the sterilization temperature completely. If you happen to meet a contaminated egg, you will have to ask for help.

3. Flavor and taste.

Diners have the final say. Just as tofu brain should be sweet or salty, it is subjective and inconclusive in taste.

So, if you like boiled eggs, naturally there is no problem; If you like eggs, you need to weigh between delicious and safe.

Of course, being risky doesn't mean you can't eat it. If the production and management of eggs are good and the eggs themselves are not infected by bacteria, then the eggs are still safe.

It is recommended to buy qualified and well-preserved eggs from large supermarket chains, so that the possibility of bacterial infection is less.

three

Can't eggs be eaten with soy milk?

This statement is widely circulated.

The explanation given is:

There is trypsin inhibitor in soybean milk, which will inhibit the digestion of protein and affect the absorption of nutrients in eggs.

But actually, we all drink boiled soybean milk. Trypsin inhibitor has long lost its activity in the process of boiling soybean milk, and no longer has the effect of inhibiting protein digestion.

So don't worry, when you drink soybean milk for breakfast, please mix it with boiled eggs, tea eggs and poached eggs at will. Don't worry at all.

However, if you like to drink raw eggs in hot soybean milk, because the temperature of hot soybean milk is not enough to cook the eggs, you should consider the food hygiene and safety problems mentioned above.

How many eggs can I eat a day?

Most friends who ask this question are afraid of cholesterol in eggs, and they are afraid that if they eat too much, they will exceed the standard.

It is generally believed that the more cholesterol you eat, the higher the cholesterol content in your blood, and the higher the risk of coronary heart disease.

However, many studies have found that it is undeniable that "eating eggs leads to hypercholesterolemia"

Blood cholesterol level has little to do with daily total cholesterol intake, but has a great relationship with fat intake and activity intensity.

Therefore, for healthy adults, if they like to eat eggs, eating two or three eggs a day is not a big problem.

Of course, because too much protein will increase the burden of liver and kidney. Therefore, if there is a problem with liver and kidney function, you should consult a doctor first and then have a big meal.

five

Are earth eggs better?

1. Nutrients

Breeds, feeding methods, etc. It may have a certain effect on the nutritional composition of eggs.

By analyzing the composition of local eggs and foreign eggs, we can always find some differences in indicators. However, this difference may also occur between different local eggs or different foreign eggs.

In addition, compared with nutrients (protein, fat, vitamins, minerals, etc.). ).) The whole egg is provided, and these differences are insignificant, which is not enough to judge which one is "better in nutrition".

2. Taste and flavor

There is a difference. When native chickens eat insects and chicken food in the environment, some fat-soluble flavor components will be transferred to eggs, making them have different flavors.

But which tastes better is actually subjective.

Under different cooking methods, most people may not eat these substances that affect the taste and flavor.

If you think the earth eggs taste better, you are willing to buy them. It doesn't matter.

3. Safety and health sector

It should be emphasized that native chickens are more susceptible to infection than native chickens raised in regular modern breeding factories, and the risk of soil eggs being infected by environmental pollutants is relatively higher. This needs the attention of readers and friends.

In addition, it is difficult for inexperienced consumers to tell the difference between unearthed eggs and ordinary eggs. You need to keep your eyes open when you buy it, and don't waste money.

Does hairy egg have health care function?

Hairy eggs are fertilized eggs that are not fully hatched.

One is that in the process of chicken hatching, due to improper temperature, pollution and other reasons, the embryo stops developing and becomes a "dead egg";

The other is to artificially terminate the eggs hatched 14-2 1 day to make food.

When raw eggs are heated and cooked, there will be some soup, solidified protein and some shaped chicken organs.

The popularity of hairy eggs is largely due to people's "belief" that it is more nutritious and even has some "special effects".

However, the study found that raw eggs do not have more or more special nutrients than ordinary eggs, and the so-called "efficacy" is not reliable!

If it's for "nutrition" or the legendary "efficacy", then don't bother. Eating normal eggs is safe and reliable;

If it is for "delicious" or "curious", it is understandable to try it.

Moreover, the source and processing of raw eggs need to be hygienic to avoid potential safety hazards.

How to avoid buying fake egg?

A video posted on the Internet shows that the cooked egg yolk can bounce on the table, just like table tennis.

"Rubber eggs!" Fake egg!' The audience was very angry.

First of all, let's talk about the causes of rubber eggs. There are two main reasons.

1. The storage time at low temperature is too long.

Real eggs are kept at low temperature for too long, even frozen, so the yolk will become hard and elastic when cooked.

2. The gossypol content in chicken feed is too high.

Cottonseed cake is the residue of cottonseed oil, which is rich in protein and cheap. It is often used as a protein source of chicken feed.

If the content of gossypol and acrylic acid in cottonseed cake is too high, it may lead to the appearance of "rubber eggs"

But "rubber eggs" are real eggs, but they are harder and more elastic, and their taste and flavor may not be so good.

The test results of the relevant departments all say that this is a real egg without exception.

What the hell is going on here? Does fake egg really exist?

No matter from the technical point of view or from the point of view of making money, we can say that it is unrealistic to produce fake egg.

Technically, it is widely rumored that fake egg protein is sodium alginate and egg yolk is sodium alginate with pigment and alkali. But the eggs made in this way only have appearance (not so similar), and will show their original shape after heating. And eggshell making is a technical job. Some reporters pay to be undercover and never learn.

From the profit point of view, fraud is to make more money. The fake way of online communication is too expensive, time-consuming and laborious. The price of the egg itself is not high, and it is really not worthwhile to fake it.

As for those weird eggs, most of them are abnormal or unqualified eggs caused by abnormal feed and hen body, not artificial eggs.

If you really encounter such an abnormality, it is recommended not to eat it and ask the merchant about the situation.
