The ratio of egg whites to yolks in eggs, which protein is higher in egg yolk or egg white?

Nutrition of egg yolks and egg whites.

Eggs from chickens, ducks, geese and other poultry are roughly the same in terms of nutritional composition, mainly composed of egg yolks, egg whites (i.e. egg whites) and egg shells. Eggs weigh about a certain amount each.

40-50 grams, duck eggs 50-60 grams, of which the yolk accounts for 32%, the egg white accounts for 57%, and the remaining 11% is the eggshell. Egg whites contain protein in addition to about 70% water.

Egg protein is extremely rich in essential amino acids.

And the composition ratio is very suitable for the needs of the human body, and this protein is the most utilized in the human body. Most of the fat in eggs is in the yolk and is dispersed into fine particles, which are easily absorbed. Fat and cholesterol in egg yolks.

The content is relatively high, and inorganic salts and vitamins are mainly concentrated in the egg yolk. Inorganic salts, calcium, phosphorus and iron are abundant, so egg yolk is a good iron for infants**. Vitamins are vitamin A

Vitamin D and riboflavin.

More. In general, the nutritional value of egg yolk is higher than that of egg white, but for children over 6 months old, eating whole eggs is naturally more nutritious.

Egg yolk is higher in protein than egg white. The protein content of egg yolk is, and the protein content of egg whites is 12%.

Egg yolk contains fat, calcium, phosphorus, iron and other minerals, and is also rich in protein, vitamin A, vitamin D, vitamin B.

Protein contains protein, fat, carbohydrate, ash, calcium, phosphorus, iron, riboflavin, niacin, vitamins A and C, etc.

Nutritional value of egg yolk:

The fat in egg yolk is dominated by monounsaturated fatty acids, more than half of which is the main ingredient in olive oil, oleic acid, which is beneficial for preventing heart disease.

Vitamins are also mostly concentrated in egg yolks. Egg yolks contain valuable vitamins A and D, as well as vitamin E and K, which are "fat-soluble vitamins". The water-soluble B vitamins are also mostly found in egg yolks.

The reason why the egg yolk is light yellow is because it contains riboflavin, which is vitamin B2, which can prevent rotten corners of the mouth, glossitis, cleft lips, etc.

Various trace elements are also concentrated in the egg yolk. Egg yolk has a lot of phosphorus and a lot of iron, and all the lecithin in eggs comes from the yolk, and lecithin can provide choline to help synthesize an important neurotransmitter - acetylcholine.

Therefore, the first complementary food for babies is often egg yolk. Egg yolk is good for iron supplementation in children, and it is also good for children's brain development. The lutein and zeaxanthin contained in egg yolk can also help the eyes filter harmful ultraviolet rays, delay eye aging, and prevent eye diseases such as macular degeneration and cataracts.

The protein content in eggs is about. Eating an egg is about enough protein to replenish the body.

Eating eggs in a moderate amount of daily life can supplement a certain amount of protein for the body, provide rich raw materials for the synthesis of immune substances in the human body, and have a positive effect on improving the body's immunity for people with low resistance and susceptibility to infectious diseases. The protein in eggs can provide rich raw materials for human bone and muscle synthesis, and moderate consumption of eggs is effective in preventing sarcopenia.

Precautions for eating eggs

For every 100 grams of eggs, there are about 13 grams of protein.

Eggs are rich in protein, and the protein contained in eggs is the most complete protein, which is easier to absorb than other meats. And eating more eggs is beneficial to brain development and memory, eggs are rich in choline, especially beneficial to improve memory and reflexes, children in adolescence should eat more.

Eggs are eggs laid by hens. It has a hard shell on the outside and an air cell, egg white and yolk on the inside. Rich in cholesterol and nutritious, an egg weighs 50 grams and contains 6-7 grams of protein and 5-6 grams of fat.

The amino acid ratio of egg protein is very suitable for the physiological needs of the human body, easy to be absorbed by the body, the utilization rate is as high as 98%, the nutritional value is very high, and it is one of the foods commonly eaten by humans.

Egg protein mainly refers to the extraction of nutrients from eggs. The ratio of amino acids in this protein is ideal for absorption by the body. It is mainly divided into two types: ovalbumin and ovoglobulin, which can replenish rich energy for the human body and enhance the body's immunity.

In addition, egg protein can also promote the absorption of minerals, which is conducive to increasing the strength of bones, reducing the probability of osteoporosis, and can also assist in the symptoms of ion disorders, but it is recommended that people with allergic diseases do not eat egg protein, otherwise it may cause aggravation of allergic symptoms.

Eggs are rich in protein and have great benefits:

1. It is conducive to brain development and improves memory.

2. Beauty and beauty, delay aging.

3. Protect eyesight, and also be able to ** cataract and other eye diseases.

4. Reduce cholesterol and prevent the occurrence of major diseases such as cardiovascular disease and heart disease.

The calories of egg white (in 100 g of edible portion) is 60 kcal (251 kJ), the calorie of egg yolk (in 100 g of edible portion) is 328 kcal (1372 kJ), and the calorie of egg yolk is higher than that of egg white.

Egg whites are semi-flowing gelatinous substances in the subshell and skin, making up about 57% of whole eggs by volume 5%。The protein contains about 12% protein, mainly ovalbumin. Protein also contains a certain amount of riboflavin, niacin, biotin, calcium, phosphorus, iron and other substances.

Egg whites are divided into concentrated proteins and dilute proteins. Concentrated egg white: the part of the egg white that is close to the yolk and has a higher concentration. Dilute protein: The part of the protein close to the eggshell, the concentration is dilute.

The egg yolk is mostly located in the egg white**, and is suspended by frenulum at the poles. The volume of egg yolk is about 30% 32% of the whole egg age, and the main component is vitelline phosphoprotein, and the fat content is 282%, the fat mostly belongs to lecithin, which is one of the phospholipid classes.

In terms of human nutrition, egg yolk is rich in vitamin A and vitamin D, and contains high minerals such as iron, phosphine, sulfur and calcium.

The egg white, egg yolk seems to have more fat and cholesterol.

1.Absorb protein, usually pay attention to eating more beef and egg white, it's almost the same.

2.It is recommended that you consume high protein and high fiber foods every day, such as beef and egg whites, in large amounts. 10 egg whites a day, 4 catties of beef, 3 cups of milk.

In eggs, the egg white (i.e. egg white) accounts for about 60, and the yolk accounts for about 30And in an egg yolk, about 32 is fat, and it also contains 3 5 cholesterol, and each egg yolk contains about 200 mg of cholesterol, so egg yolk is a food with high cholesterol content. The protein in eggs contains the best and most complete essential amino acids, and the quality of egg protein is the highest in natural foods (not artificially refined proteins), and a person can meet the body's needs for essential amino acids by eating only two eggs a day.

There is also more calcium, phosphorus and iron in eggs than in meat, and there are more inorganic salts in egg yolks than in egg whites, and the iron content in egg yolks is particularly rich and easily absorbed.

Raw egg whites contain an antitrypsin, which makes raw protein less digestible and absorbed, but when the eggs are cooked, the antitrypsin is destroyed. After boiling, the egg white becomes very flaccid and is easily broken down into amino acids and absorbed by people, so eggs must be cooked and eaten, and it is not good to eat raw eggs.

Eggs are one of the most significant material cells that we can see. The yolk is the nucleus. The main components of egg yolk are protein, fat, about 48% water and 2% minerals, as well as a variety of vitamins.

People often think that the protein of eggs is concentrated in the egg white, but in fact, the protein content of egg white is only about 11. The fat is also mostly concentrated in the yolk part. The fat in egg yolk is dominated by monounsaturated fatty acids, more than half of which is the main ingredient in olive oil - oleic acid, which is beneficial for the prevention of heart disease (excerpted from the encyclopedia), 9, which protein content is high in egg whites and yolks in hard-boiled eggs?
