摘要： There is described a process for obtaining a target chemical species, in particular alginate, from seaweed. The process comprises the steps of: (i) providing a seaweed portion comprising a stipe; (ii) removing at least a portion of an outwardly facing surface of the stipe; (iii) dividing the stipe into a plurality of portions; and (iv) extracting the target chemical species from the plurality of stipe portions. The outwardly facing surface of the stipe may be removed by peeling or abrading and the stipe may be divided into a plurality of portions by milling. Also described is alginate, alginic acid or an alginate derivate, or a salt thereof obtained by the process.

摘要： There is described a process for obtaining a target chemical species, in particular alginate and/or cellulose, from seaweed. The process comprises the steps of: (i) providing a seaweed portion; (ii) bleaching the seaweed portion; and (iii) extracting the target chemical species from the seaweed portion; wherein the bleaching comprises a neutral or alkaline bleaching step, the neutral or alkaline bleaching step comprising using a bleaching composition under neutral or alkaline conditions. The neutral or alkaline bleaching step may precede the extraction step. Also described is alginate, an alginate salt, alginic acid, an alginic acid salt, an alginate derivative, an alginate derivative salt, cellulose, and/or a cellulose derivative obtained by the process.
