Porphyra is nutritious and delicious, and it is rich in protein, inorganic compounds, unsaturated fatty acids, vitamins and minerals, among which protein is as high as 25%~50%, which has broad prospects in the fields of food and medicine. ?

Porphyra polysaccharide and phycobiliprotein have anti-aging, anticoagulant and hypolipidemic effects. Porphyra has a strong ability to absorb nitrogen, phosphorus and fix carbon, and its culture also plays an important role in the repair and improvement of eutrophication in shallow sea.

The contents of calcium, sodium, potassium, magnesium and phosphorus in laver are very high. From the point of view of nutrition, it is significant that the ratio of Na/K in laver is less than 1.2.

Extended data:

Porphyra species are distributed in cold, temperate, subtropical and tropical waters, but the species diversity in subtropical to temperate waters is rich.

The geographical distribution of laver in China also follows this law, mainly distributed in the intertidal zone from the Yellow Sea and Bohai Sea to the southeast coast. In addition, a few species of laver are distributed in the coastal areas of Taiwan Province Province and Hainan Island, and their distribution has regional characteristics.

Porphyra species naturally distributed in the Yellow Sea and Bohai Sea include Porphyra yezoensis, Porphyra yezoensis and Porphyra hemiphylla. Porphyra yezoensis, Porphyra rugosa and Porphyra yezoensis are mainly distributed in the southeast coast.
