Riboflavin (vitamin B2) is an essential water-soluble vitamin used as a yellow food colorant (E101). It naturally occurs in meat, fish, dairy, eggs, and leafy greens. Commercial riboflavin for food use is produced by bacterial fermentation (primarily using Ashbya gossypii or Bacillus subtilis). It provides a yellow-to-green-yellow color in foods.
Provides a natural yellow color in cheeses, pasta, vitamin-enriched products, and energy drinks; also functions as a nutritional supplement (vitamin B2).
Riboflavin is one of the safest food additives. It is an essential nutrient with no established upper tolerable intake limit due to its extremely low toxicity — excess riboflavin is simply excreted in urine (which turns bright yellow). No carcinogenicity, teratogenicity, or mutagenicity has been identified.
