VITAMIN B2 (RIBOFLAVIN)
Chemical Formula: C17H20N4O6 Molecular Weight: 376.37 CAS No.: 83-88-5
Function:
VB2 is mainly made by the raw materials of glucose and peptone through biological fermentation, membrane filtration, crystalization and spraying&drying. It is a free flowing particle and nutrititional additive for domestic animals to speed growth and prevent the illness. It can be easily dissolved in slightly alkalescent liquors but hardly in water and ethanol. The dry product has a good stabilization in oxidant and acid substance or in high heat condition. It will be quickly break down in alkalescent liquors or underUV light. so it must be preserved in enveloped and non-light ray conditions. At the same time, it better not be mixed with alkalescent substances.
