Description
Additional Information
English Name: Casein; β-Casein
Other Names: Cheese protein; Casein; Casein protein; Casein powder; Casein glue; Casein acid
CAS Number: 9000-71-9
Molecular Weight: Approximately 57,000–375,000
Grade: BR
Content (N basis): ≥14.0%
Moisture: ≤10.0%
Soluble Matter: ≤0.5%
Specific Gravity: 1.25–1.31
Fat: ≤0.4%
Residue on Ignition: ≤2.0%
Properties: White or light yellow amorphous powder or granules. A phosphorus-containing complex protein. Odorless. Tasteless. Hygroscopic. Stable when dry, deteriorates easily when moist. Soluble in alkaline aqueous solutions, soluble in concentrated hydrochloric acid with a light purple color, almost insoluble in water and non-polar organic solvents. Rapidly swells when immersed in water, but particles do not aggregate. Relative density 1.25–1.31. Isoelectric point pI 4.7.
Uses: Biochemical research. Raw material for culture media. A versatile additive in light industry, used as an adhesive and gloss enhancer in the paper and stationery industries, as a polishing paste and pigment paste material in the leather industry, as a hydrolyzed protein material and medical glove material in the pharmaceutical industry, as a glazing agent material in the printing industry, and widely applied in furniture manufacturing, food, precision electronics, bioplastics, protein cellulose, high-end artwork, and other fields.
Storage: RT, shelf life 3 years
