RIBOFLAVIN DC GRADE - Introduction
Vitamin B2 is an easily absorbed micronutrient, which plays a key role in maintaining the health of people and other animals. Riboflavin is a key component of the redox cofactor flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN). FAD and FMN are required for various flavin oxidoreductase, dehydrogenase, decarboxylase and electron transport.

RIBOFLAVIN DC GRADE - Application
Open Data Verified Data
vitamin B2 is a vitamin that promotes the growth and development of the body. It can participate in many redox reactions in the body and promote the growth by promoting the oxidative decomposition of carbohydrates, lipids and proteins. Lack of vitamin B2, will lead to the decline of tissue respiration, the body's metabolic process disorders. Susceptible to conjunctivitis, mouth fire, glossitis and other symptoms. China's provisions can be used for salt, the use of 100 ~ 150mg/kg; The maximum use of 10 ~ 13mg/kg in solid beverages; The use of 4 ~ 8mg/kg in baby food; the amount used is 3.0~5.0 mg/kg in cereal and its products, and 1~2 mg/kg in drink and milk drink. Also available as a yellow colorant.
