Exclusivement utilis\u00e9es comme engrais dans l\u2019Antiquit\u00e9, puis incorpor\u00e9es sous forme de cendres dans la fabrication du verre au XVIe si\u00e8cle, les algues sont aujourd\u2019hui produites \u00e0 97 % \u00e0 des fins alimentaires. Sur environ 30 000 esp\u00e8ces d\u2019algues connues dans le monde, seules quelques dizaines sont exploit\u00e9es commercialement. Parmi elles, les algues carragh\u00e9nophytes, \u00e9galement appel\u00e9es chondrus ou lichens d\u2019Irlande, sont utilis\u00e9es comme g\u00e9lifiants, \u00e9paississants ou stabilisants par les industries agro-alimentaire, pharmaceutique et cosm\u00e9tique. La production de ces algues rouges, avec 5,2 millions de tonnes en 2008, repr\u00e9sente un peu plus d\u2019un quart de la culture et de la collecte des algues dans le monde. En Extr\u00eame-Orient, la culture de ce type d\u2019algues repr\u00e9sente une source de revenus int\u00e9ressante pour les populations c\u00f4ti\u00e8res. Les boutures d\u2019algues sont fix\u00e9es sur des cordages immerg\u00e9s, tendus entre des pieux, suivant le courant principal. Toutes esp\u00e8ces d\u2019algues confondues (vertes, rouges et brunes), l\u2019Indon\u00e9sie avec 13,7 % de la production mondiale en 2008 se place au deuxi\u00e8me rang des producteurs, un march\u00e9 domin\u00e9 par la Chine (62,8 % de la production mondiale), devant les Philippines (10,6 %), la Cor\u00e9e du Sud (5,9 %) et le Japon (2,9 %). En revanche, en chiffre d\u2019affaires, le Japon reste au second rang mondial derri\u00e8re la Chine, \u00e0 cause de sa production de Nori (Porphyra spp.), une algue de grande valeur qui entre dans la composition des makizushi, ces rouleaux d\u2019algues s\u00e9ch\u00e9es entourant du riz et farcis de poisson cru.<\/p>\n","protected":false},"excerpt":{"rendered":"
