387 Irish moss Chondrus crispus Chondrus crispus ? commonly called Irish moss or carrageen moss (Irish carraigín, "little rock") ? is a species of red algae which grows abundantly along the rocky parts of the Atlantic coast of Europe and North America. In its fresh condition this protist is soft and cartilaginous, varying in color from a greenish-yellow, through red, to a dark purple or purplish-brown. The principal constituent is a mucilaginous body, made of the polysaccharide carrageenan which comprises about 55% by weight. The organism also consists of nearly 10% protein and about 15% mineral matter, and is rich in iodine and sulfur. When softened in water it has a sea-like odour and because of the abundant cell wall polysaccharides it will form a jelly when boiled, containing from 20 to 100 times its weight of water. 12092 Chondrus_crispus 387.jpg image/jpeg 150815 2012-04-20T09:41:13Z 414 Aquatic foods Seaweed Type 1 2011-02-09T00:37:38Z 2019-05-14T18:05:24Z false specific 2769 true FOOD00382
