Content of Ascorbic acid in lime fruit

[marilu]

What are the effects of light and dark storage on ascorbic acid content of lime fruit? Do you expect the contents to be very different and why???

Ascorbic acid gets easily oxydised by oxygen and the oxydation process is accelerated by placing it in open air together with direct sunlight...

I don't think ascorbic content will be too different, lime fruit is not so sensitive to light.

Oh, for testing the quantity of ascorbic acid (to differ it from citric acid), you can use ascorbic acid's reductor potential.
You can react it (sample that contains the mixture of ascorbic acid and another compounds) with Triiodide ion.
