Undaria pinnatifida is a kind of large seaweed with rich nutrition and delicious taste, and its iodine content is second only to kelp. According to research, the edible part of Undaria pinnatifida contains protein 65438±05g, alginic acid 28.8g, fat 3.2g, sugar 35.3g, crude fiber 2.7g, ash 30.8g, water 65438±03g and mannitol 65438±00.9g. Undaria pinnatifida is a kind of temperate algae, which contains alginic acid, dietary fiber, various physiologically active substances, trace elements such as iodine, potassium and calcium, and various vitamins, including vitamin A53.6 mg, vitamin B 1-0.28 mg, vitamin B2- 1.32 mg, and all amino acids necessary for human body, including arginine, leucine and vitamin C. Undaria pinnatifida is easy to digest because its fiber content is only 2.7%. In addition, Undaria pinnatifida also contains a variety of unsaturated fatty acids, among which the contents of triene and hexaene unsaturated fatty acids are the highest, reaching per gram 10 microgram, glycyrrhetinic acid 1800 IU, fucoidan 25.4 mg, alginate 6.9 mg, nicotinic acid 8 mg, and other natural nutrients needed by human body.
The content of carotene in Undaria pinnatifida is quite high. Vitamin A decomposed from carotene is a low molecular weight organic compound necessary for maintaining health, which can promote the synthesis of protein in vivo, accelerate the growth and development, participate in the synthesis or regeneration of rhodopsin in eyeball, maintain normal vision and play an important role in preventing cancer. In addition, carotene itself has a good effect on cancer prevention. If Undaria pinnatifida is eaten with oil, the absorption rate of carotene in human body can be increased by 3 times.
Undaria pinnatifida is also rich in trace elements, including calcium 65438 0300 mg, phosphorus 400 mg, iron 7 mg, sodium 665438 000 mg, potassium 5500 mg, copper 340 mg, manganese 950 mg, nickel 460 mg, zinc 9.5 mg and cobalt 65438 06 mg. Copper is an effective component of many oxidases and blood in the body; Zinc has the functions of antioxidation, anti-aging and participation in the growth and metabolism of the body.
