I am working in a company who produces vitamin-mineral premixes:
In our laboratory we have HPLC to batch control of vitamins...
Somehow we noticed that Ferrous Fumarate or Ferrous Sulphate (premix also contains iron) mask or decrease folic acid around 60%.
Does anyone familiar with this problem? Is it a masking or is it a decreasing?
Thanks in advance.
