Agar-agar is sold as flakes, powder, bars, and strands. The seaweed is typically boiled into a gel, pressed, dried, and how to desulphate a battery crushed to form agar flakes, blended into a powder, freeze-dried into bars, or made into strands.

Best known as a solidifying component of bacteriological culture media, it is also used 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.
Although agar is insoluble in cold water, it absorbs as much as 20 times its own weight. In its natural state, agar occurs as a complex cell-wall constituent containing the polysaccharide agarose with sulfate and calcium. Additional Info. More About Contributors Article History.
