DESCRIPTION

Kelp occurs as a dark green to olive brown, dry substance. It is the dehydrated seaweed obtained from the class Phaeophyceae (brown algae) of the genera Macrocystis (including M. pyrifera and related species) and Laminaria (including L. digitata, L. cloustoni, and L. saccharina). The seaweed may be chopped to provide coarse particles and/or it may be ground to provide a fine powder.
