▪ seaweed product
also called  Agar-agar,  

      gelatin-like product made primarily from the algae Gelidium and Gracilaria (red seaweeds). Best known as a solidifying component of bacteriological culture media, it is used also in canning meat, fish, and poultry; in cosmetics, medicines, and dentistry; as a clarifying agent in brewing and wine making; as a thickening agent in ice cream, pastries, desserts, and salad dressings; and as a wire-drawing lubricant. Agar is isolated from the algae as an amorphous and translucent product sold as powder, flakes, or bricks. It is produced chiefly in Japan, New Zealand, Australia, the United States, and Russia. Although agar is insoluble in cold water, it absorbs as much as 20 times its own weight. It dissolves readily in boiling water; a dilute solution is still liquid at 42° C (108° F) but solidifies at 37° C into a firm gel. In the natural state, agar occurs as a complex cell-wall constituent containing a complex carbohydrate (polysaccharide) with sulfate and calcium.
