Vitamins In Foods: Analysis, Bioavailability, and Stability
17.9 Vitamin C An effective means of extracting vitamin C from foods is
homogenization with a solution of 3% (w/v) metaphosphoric acid dissolved in 8%
glacial acetic acid [70]. This extracting solution denatures and precipitates
proteins ...

It is effective for copper chelation in metaphosphoric acid and trichloroacetic acid,
but ineffective for oxalic acid chelation. All extraction procedures should be
completed rapidly in subdued light to limit light- catalyzed oxidative reactions.

Extracts containing vitamin C are thus prepared in metaphosphoric acid or glacial
acetic acid, which inactivates the enzyme ascorbic acid oxidase naturally present
in food stuffs, hence preventing the atmospheric oxidation of ascorbic acid.
