…among the most nutritious seaweeds, with a protein content of 30–50 percent, and about 75 percent of that is digestible. The addition of nori to a meat system increases protein content, as well as the levels of some amino acids such as serine, glycine, alanine, valine, tyrosine, phenylalanine and arginine.

Sugars are low (0.1 percent), and the vitamin content very high, with significant amounts of Vitamins A, B1, B2, B6, B12, C, niacin and folic acid, but the shelf life of vitamin C can be short in the dried product. The sulfated polysaccharides from the marine algae Porphyra haitanesis (Zhang et al., 2003), Ulva pertusa (Qi et al., 2005), Fucus vesiculosus (Rupérez et al., 2002), Laminaria japonica (Xue et al., 2004) and Ecklonia kurome (Hu et al., 2001) have been demonstrated to possess antioxidant activity and to protect from photooxidative stress induced by ultraviolet radiation (Aguilera et al., 2002). 0000028701 00000 n Nets may be routinely harvested 6–8 times during the growing season (every 15–20 days), with yields of more than 3300 standard sheets (approximately 20 cm × 20 cm) per year.

The Pen-ts’ao recommended all the medicinal algae in goiter therapy (Laminaria digitata, Laminaria saccharina, Fucus vesiculosus, Sargassum).

In addition, the seaweed is rich in vitamins A, C, and B12. However, to date one of the most important traditional Chinese medicine claims for Sargassum, treating thyroid-related diseases (eg, goiter), has not been sufficiently researched (Liu et al., 2012). The incorporation of nori produced a considerable increase in the Fe content of the meat system (López-López et al., 2009a). F.J. Sánchez-Muniz, ... J.
