溶解性：Agar is strongly hydrophilic and can slowly absorb about 20 times its weight of cold water, swelling in the process.1 Sigma tests the solubility of agar powder in water at 1 mg/ml with boiling, and obtains a clear,
colorless solution. Agar is not soluble in alcohol.

琼脂粉应用说明：Agar is used in microbiology and bacteriology to make solid culture media for microorganisms; as an antistaling agent in bakery products, confectionery, meats and poultry; as a gelling agent is cosmetics,
desserts and beverages; as a corrosion inhibitor; in sizing for paper and silks; in adhesives; in the dyeing and printing of textiles and fabrics; and as a protective colloid in ice cream, pet foods, health foods,
laxatives, pharmaceuticals, dental impressions, lab reagents and photographic emulsions.
