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.

it has been suggested that the sourness of citrus fruit id dependent on its citric acid content. using lime,orange and grapefruit how do i go about proving this to be true or not? i would greatly appreciate the help

i am not very sure but how does light make a difference is it a photochemical reaction or is it that the temperature change results in the differrence

ok so how is it that your suggestion relate to measuring the content of ascorbic acid in each citrus?

All citrus fruits contain ascorbic acid, also called vitamin C, and are considered acidic fruit. The higher the ascorbic acid content, the better the taste and quality of the fruit. Oranges, lemons, limes, grapefruit and other citrus fruits are among the most detoxifying foods and also contain other important nutrients such as vitamin A. Citrus fruits also contain citric acid and pantothenic acid, which is a B vitamin that helps to oxidize fats, carbohydrates and some amino acids.
