Abstract:
The invention relates to a process for the purification of riboflavin comprising the steps of (a) precipitating a first crystalline form of riboflavin, (b) isolating the first crystalline form of riboflavin, (c) transforming the first crystalline form of riboflavin into a second crystalline form of riboflavin under conditions that decompose diluted DNA, and (d) isolating the second crystalline form of riboflavin, provided that at ambient temperature the first crystalline form of riboflavin is thermodynamically less stable than the second crystalline form of riboflavin.
