A novel phosphorus-containing product extracted from rice bran, a rice production by-product from the Far Eastern selection, was isolated. Its composition and structure were determined by chemical methods and IR (Infrared), NMR (Nuclear Magnetic Resonance) (1H, 13C, 31P) spectroscopy, and X-ray phase analysis. Physicochemical characteristics such as moisture, bulk density, pH of the aqueous suspension, and water solubility under different conditions of the phosphorus-containing product were obtained.
