Than the rotation: - 135 DHS (c = 5, 0.05 M NaOH) The refractive index: - 135 ° C = 0.5, JP Method) Storage conditions: 2-8 ° C Water solubility: 0.07 g/L (20 DHS C) Chemical properties Yellow to orange, crystalline powder, slight odor, taste bitter.Melting point 280 ℃ (decomposition).Soluble in alkaline solution and sodium chloride solution, slightly soluble in water, slightly soluble in ethanol, insoluble in ether and chloroform.Aqueous solution is yellow-green, saturated aqueous solution is neutral.Good heat resistance, acid resistance, or the ultraviolet irradiation in the alkaline solution is vulnerable to damage, the reducing agent is unstable.By intraperitoneal injection of rat LD50560mg/kg, ADI 0 ~ 0.5 mg/kg (FAO/WHO, 1994). use Vitamin B2 is to promote the body growth and development of the vitamin, play an important role in the process of human metabolism.Lacking, susceptible to conjunctivitis, angular stomatitis, glossitis, etc.Rules can be used in the salt in our country, the use of 100 ~ 150 mg/kg;In the solid beverage maximum usage of 10 ~ 13 mg/kg;In infant food usage of 4 ~ 8 mg/kg;In grains and their products usage is 3.0 ~ 5.0 mg/kg;In the drink liquid, beverage usage is 1 ~ 2 mg/kg.Also can be used as a yellow stain. use Used in the treatment of riboflavin deficiency, conjunctivitis, alimentary ulcer, general nutritional disorders and other diseases use Biochemical studies, used in the polymerization of acrylamide gel photocatalyst, nutrients, clinical medicine belongs to the vitamin B group, participates in the metabolism of sugar, fat, protein and maintain normal visual function, promote growth.Clinical treatment for angular stomatitis, glossitis, caused by a lack of vitamin B2 and so on. use Riboflavin is green vegetables, beans, rice, wheat, yeast, liver, heart and milk class, riboflavin in vivo distribution in each organization, in vivo alternates hydrogenated system are composed of the coenzyme, involved in REDOX reaction and transfer the role of the hydrogen atom.When riboflavin lack, can affect biological oxidation, and make the metabolic disorder, caused by the disease develops in mouth, eyes, genitals, such as deficiency, cheilitis, conjunctivitis, scrotal phlogistic etc.Riboflavin is mainly used as pharmaceutical, food additives and feed additives, in terms of medicinal, used in compound vitamin or vitamin B2, also used as a sugar pill and capsules yellow stain.When used as a food additive, on the one hand, has the effect of strengthening nutrition, on the other hand also as yellow stain.By intraperitoneal injection of rats LD50 to 560 mg/kg. use Comparing with vitamin B2 use Usage and feature: for yellow enzymes in the body part of prosthetic group (yellow enzymes play a role of hydrogen in the biological oxidation reduction), when a lack of will affect the body's biological oxidation, the metabolic disorder.
