There is a difference in nutritional value. Bird's nest has a higher protein content than silverbeet, especially in the amino acids it contains than silverbeet.
The main nutrient in bird's nest is protein, of which there is one essential amino acid (lysine). Bird's nest is rich in amino acids, including phenylalanine, valine, leucine, tyrosine, arginine, etc. The hydrolyzed amino acid content of bird's nest is also rich in lysine. The hydrolyzed amino acid content of bird's nest is 42.272%, and the essential amino acid content accounts for 42% of the total amino acid content.
Meanwhile, the amino acids characteristic of fresh flavor (aspartic acid and glutamic acid) and the amino acids characteristic of aromatic flavor (tyrosine and phenylalanine) were in high content, indicating that bird's nests have a delicious flavor.
The nutritional value of food mainly depends on the type, quantity and proportion of amino acids contained. The Food and Agriculture Organization of the United Nations (FAO) and the World Health Organization (WHO) have proposed a reference pattern spectrum of essential amino acids in food, which stipulates that the mass ratio of essential amino acids to total amino acids as well as the mass ratio of essential amino acids to non-essential amino acids are 40% and 60% respectively.
The chemical composition of silver fungus is more complex, preliminary analysis proved that the silver fungus contains protein 6.7%-10%, 65%-71.2% carbohydrates, 0.6%-12.8% fat, 2.4%-2.75% crude fiber, inorganic salts, 4.0%-5.4%, 15.2%-18.76% water and a small amount of vitamin B.
The protein of ginkgo contains leucine, isoleucine, phenylalanine, amino acid, serine, glutamic acid, fetuidine, proline, arginine, lysine, alanine, threonine, aspartic acid, tyrosine, cystine, histidine, methionine and other 17 kinds of amino acids, of which the largest content is proline. Inorganic salts mainly contain sulfur, iron, magnesium, calcium, potassium and other ions.
Extended information
Specific role of silver fungus:
1, white fungus contains protein, fat and a variety of amino acids, minerals and liver sugar. Silver fungus protein contains 17 kinds of amino acids, the body's essential amino acids in the 3/4 silver fungus can provide. Silver fungus also contains a variety of minerals, such as calcium, phosphorus, iron, potassium, sodium, magnesium, sulfur, etc., of which calcium and iron content is very high, in each 100 grams of silver fungus, containing calcium 643 mg, iron 30.4 mg.
In addition, the silver fungus also contains alginate, polypentose, mannitol and other liver sugar, high nutritional value, with the role of supporting the strong, is a senior nourishing tonic.
2, white fungus can improve liver detoxification capacity, liver role; silver fungus on the elderly chronic bronchitis, pulmonary heart disease has a certain effect.
3, white fungus is rich in vitamin D, can prevent the loss of calcium, very beneficial to growth and development; because rich in selenium and other trace elements, it can enhance the body's anti-tumor immunity.
4, white fungus can also enhance the tolerance of tumor patients to radiotherapy, chemotherapy.
5. White fungus is rich in natural plant-based gelatin, which has a good protective effect on the skin.
6, white fungus in the dietary fiber can help gastrointestinal peristalsis, reduce fat absorption, so as to achieve the effect of weight loss.
7, white fungus in the active ingredient acidic polysaccharides.
8, white fungus has a strong essence, tonic kidney, lubricate the intestine, benefit the stomach, tonic gas, and blood, strong heart, strong body, brain, refreshing, beauty, rejuvenation, prolonging the efficacy of life.
9, because the white fungus contains a lot of water, after absorbing water volume expanded ten times, has a good laxative effect.
