Food Grade Riboflavin Vitamin B2 CAS 83-88-5 Nutritional Fortifier & Colorant

Riboflavin (Vitamin B2, Lactoflavin, CAS:83-88-5,EINECS:201-507-1, HS Code:2936230000, molecular formula C₁₇H₂₀N₄O₆, MW:376.36) is an orange-yellow crystalline powder with a slight odor and bitter taste, produced via advanced microbial fermentation or chemical synthesis processes followed by multi-stage purification and crystallization. Our food grade riboflavin strictly complies with GB 14752-2010, FCC, USP and EU food safety standards, with purity ranging from 98.0% to 102.0%. It is slightly soluble in water, forming a yellow-green fluorescent solution, and insoluble in ethanol and ether. As an essential water-soluble B vitamin, it plays a critical role in energy metabolism, cell respiration and antioxidant defense systems. It also serves as a natural yellow food colorant (INS 101), providing both nutritional value and appealing color to food products.
