Description
Detection principle
The most obvious chemical activity of VC is that reduce Fe3+ to Fe2+, then promote iron absorption in the intestine, promote the storage and utilization of iron. Fe3+ react immediately with reducing ascorbic acid to form Fe2+. then Fe2+ react with phenanthroline and the color developing reaction occurs. The content of vitamin C in sample can be determined. Measure the OD value and calculate the VC content indirectly.

Dilution of sample
It is recommended to take 2~3 samples with expected large difference to do pre-experiment before formal experiment and dilute the sample according to the result of the pre-experiment and the detection range (0.31-20 μg/mL).
The recommended dilution factor for different samples is as follows (for reference only):
