Agar Agar Powder

Agar consists mainly of high molecular weight polysaccharides extracted from Gracilaria seaweed,agar is a very popular food material,but its uses are not limited to the food industry,but also expanded to applications on biotechnical and medical science,healthcare and nutritional industry,manufacture of cosmetic products as well as agriculture,agagr contains more dietary fibers than 80%compared with any other foods.In Food Industry, Agar has the following characteristics: Stable and coagulating, can be widely used in producing drink, icecream, sugar, canned food, meat products etc, as coagulant, densifying agent, emulsifyingagent, keeping fresh agent, stabilizing agent, floation agent. In chemical Industry and Medicine & Science Research, Agar is used as ointment-base and cultivate-base and so on.Apperance white to yellowish-white or pale yellow powderLoss on drying ≤22%(105°C,5h) Ash ≤6.5%(on the anhydrous basis determined at 550°C) Acid-insoluble ash ≤0.5%(insoluble in approximately 3N Hydrochloric,550°C) Water-insoluble matter ≤1%(in hot water) Starch Not detectable by the following method: to a 1 in 10 solution of the sample add a few drops of iodine solution.
