Dear all,
I'm looking for informations about vitamins stability (both water&fat soluble).
I've done several HPLC analysis in different kind of dietary supplements (tablets, powder, liquid, ..) and I've found that, for example, Folic Acid is less stable in liquids than in powder (at same storage conditions). I'd like to know if, in your opinion, this is a common behaviour for this vitamin.
I'm also looking for the paper "A study of folic acid stability in solutions of the B complex vitamins" by Alfred R. Biamonte,George H. Schneller or similar.
Thank you!
Antonella
Having works on stability on products used for humanitarian food aid, we found through accelerated shelf-life studies that Vit A persists in lipid-based products extremely well, but vit C and other water solubles disappeared almost completely within 6 months when packaging was ineffectively protecting from light, moisture and heat. So much depends on the packaging, not only on the matrix of the supplement or food itself.
Vitamins are of great help in growth of fishes. I have worked in formulating fish feed and have added vitamins after the protocol of heating, boiling etc, so that vitamins are not denatured in the process and are available to fish through formulated feed
