Product Introduction

Riboflavin is a water-soluble B vitamin, named from the Latin word "flavus" (yellow) due to the deep yellow color of its pure crystals. It consists of an isoalloxazine ring and a ribityl side chain, appearing as yellow needle-like crystals with a bitter taste. The human body cannot synthesize it and must obtain it from food.

Riboflavin is widely found in both animal and plant foods. The richest natural sources include:
Animal sources: Liver (beef, lamb, chicken), kidney, heart, eggs, dairy products, lean meats
Plant sources: Green leafy vegetables, mushrooms, almonds, wheat germ and bran
Others: Yeast (the richest natural source)

Currently, riboflavin is mainly produced through the following methods:
Biological fermentation: Using Eremothecium ashbyii, Ashbya gossypii, Clostridium acetobutylicum, or genetically engineered strains (e.g., Bacillus subtilis) for submerged fermentation.
Chemical synthesis: Using D-ribose and 3,4-dimethylaniline as starting materials.
