Porphyra and egg soup is a kind of instant soup, which is a traditional after-dinner soup in Sichuan. Its main ingredients, laver and eggs, have high nutritional value and are widely loved because of their simple preparation and rich nutrition.
Protein, iron, phosphorus, calcium, riboflavin, carotene, etc. It is the edible part of laver.
Laver egg flower soup ranks first among all kinds of vegetables, so laver has the reputation of "nutritional treasure house".
(1) The bioactive substances in protein and amino acid laver are very important to the life activities of plants. Generally, the protein content of edible laver is 24%-28%, which is much higher than that of ordinary vegetables, and there are many essential amino acids. Porphyra protein contains many neutral and acidic amino acids, such as alanine, aspartic acid, glutamic acid, glycine, proline and so on, which are characteristics that all terrestrial vegetables and plants do not have.
(2) Compared with terrestrial plants, the fat content of laver is lower, mostly below 65438 0%, and palmitic acid accounts for the vast majority of saturated fatty acids, about 20%; The contents of onion acid and stearic acid in beans are less, accounting for 2% respectively; Unsaturated fats-linoleic acid, linolenic acid or octadecatetraenoic acid, which have a good health care effect on human body, contain a large amount of 10%-30%, and highly unsaturated fatty acids above C20 also contain a certain amount. Even better, the content of eicosapentaenoic acid in laver, which is known as "brain gold", is as high as 30%.
(3) Vitamins Porphyra contains a variety of vitamins, and the content of B vitamins is not inferior to that of vegetables. The content of B vitamins in laver is very high, especially vitamin B 12, which hardly exists in terrestrial plants. In terms of dry matter, the content of vitamin B 12 is similar to that of fish, and the content of vitamin C is also very high. Vitamin B 12 has the functions of activating cranial nerves, preventing aging and memory decline, and improving depression.
(4) Inorganic substances: Seawater is extremely rich in inorganic substances, and laver can absorb and accumulate inorganic substances in seawater, because some lavers are extremely rich in inorganic substances.
